Description

The invention relates to a triggering element, in particular an emergency button, for unlocking at least one door lock, in particular for securing escape routes, the triggering element comprising lighting means for displaying a locked and/or unlocked state of a door lock. The invention also relates to a safety system with a triggering element according to the invention, in particular an emergency button.

Emergency buttons and safety systems for securing escape routes are known. The emergency button includes at least light sources with which a locked state and an unlocked state of a door lock can be visualized. The lamps light up green when unlocked and red when locked. The user receives information from the light source as to whether the door is unlocked and the user can escape through the door. By flashing the lamps, it can be signaled that the door is only open for a certain period of time. The disadvantage here is that only these states are displayed to the user by the lighting means. Other statuses of the security system are not indicated by the lamps.

It is therefore the object of the invention to provide a triggering element, in particular an emergency button, and a safety system which at least reduces the disadvantage mentioned above. In particular, it is the object of the invention to provide a triggering element, in particular an emergency button, which indicates at least one further state of the safety system in a simple design.

This object is achieved by a triggering element, in particular an emergency button, according to independent claim 1. Advantageous developments of the triggering element are specified in the dependent claims, the description and in the figures. A safety system with a triggering element according to the invention is also protected. Advantageous developments of the security system are specified in the dependent claims, the description and in the figures. Features and details that are described in connection with the triggering element according to the invention also apply in connection with the safety system according to the invention and vice versa. The features mentioned in the description and in the claims can each be essential to the invention individually or in combination.

Based on the triggering element described at the outset, the previously derived and presented object is achieved in that the lighting means can each be controlled in at least two groups. Because the light sources can be controlled in at least two groups, each group can light in a different way emit. It is thus conceivable that not all groups of lighting devices emit light at the same time, emit light of the same color and/or flash at the same frequency. By controlling each group individually, the number of options for displaying at least one additional status of the security system to the user through the lighting means can be increased immensely.

The total number of light sources of the triggering element is denoted by n. A group can contain 1 to n-1 lamps in such a way that the number of lamps in the groups add up to n. In particular, at least one of the light sources can be controlled individually. A group of light sources can therefore also include only one light source. At least several of the light sources can preferably be controlled individually. Each light source can particularly preferably be controlled individually. In this case, the triggering element includes n groups of light sources, each group including only one of the light sources.

The lamps, which are already used to indicate the locked and/or unlocked state, can be controlled in groups, in particular individually. As a result, the lighting means can also be used to display the at least one further state of the security system. The triggering element according to the invention can therefore be produced without using additional components, in particular additional lighting means. A triggering element that indicates at least one further state of the safety system in a particularly simple manner is thus made available. At least the locked or the unlocked state of the door lock is preferably displayed by all the lamps. This can be z. B. be the locked state of the door lock. In particular, the unlocked state and the locked state can be displayed by all light sources.

The triggering element can comprise an actuating element. The actuating element can be actuated by a user in such a way that an actuating signal for actuating the door lock can be generated by actuating the actuating element. During actuation, the actuation element can move, in particular, from an initial position into an actuation position.

A restoring means can be used to move the actuating element back into the starting position after actuation. The restoring means particularly preferably moves the actuating element back into the starting position without manual action. Thus, the actuating element can return to the starting position immediately after the actuation. The restoring means can be designed as a spring.

The actuator may include a front surface facing the user.

The triggering element is preferably an emergency button. In this case, the actuating element corresponds to the actuating element of the emergency button. Alternatively, the triggering element can be designed as a panic bar assembly. In this case, the actuating element is designed as a panic bar. The triggering element can be designed as a fitting assembly. In this case, the actuator z. B. designed as a door handle.

Provision is preferably made for the light sources to be in the form of multiple color light sources. This means that the lamps can emit light of different colors. The lighting means can in particular be in the form of multi-color LEDs. In this case, each illuminant has a number of individual LEDs. The light sources are particularly preferably designed as RGB LEDs. The different colors can be generated in part by the simultaneous light emission of the individual LEDs of the multi-color LED. In this case, different colors can be generated by different light components of the individual LEDs.

It is conceivable that the lighting means can be controlled in such a way that light can be emitted by the lighting means in at least two, preferably in at least three, particularly preferably in at least four different colors. For example, the light sources can emit red, green, yellow and blue light. Due to the different colors, different statuses of the security system can be displayed particularly well.

The triggering element, in particular the emergency button, preferably comprises at least one triggering element processing unit, in particular an emergency button processing unit. The lighting means can particularly preferably be controlled by the triggering element processing unit. The triggering element processing unit, in particular the emergency button processing unit, can be designed digitally and/or electronically. The trigger element processing unit may include a processor. The trigger element processing unit may include at least one non-volatile memory. For example, the trigger element processing unit may be a microprocessor or microcontroller.

The lighting means can be connected to a bus, in particular a ring bus. The triggering element processing unit can control the lighting means by means of the bus, in particular the ring bus.

The lamps can be arranged in a circle. In particular, the lighting means can be arranged in a circle around the actuating element.

It is conceivable that the lighting means can be controlled in such a way that at the same time at least one lighting means lights up light in one color and another lighting means lights up in a different color emitted. So e.g. B. a bulb emit yellow light and another bulb red or green light at the same time. This can result in light patterns that are significantly perceptible to the user. In addition or as an alternative, the lighting means can be controlled in such a way that at least one lighting means periodically alternately emits light of different colors. A light source can e.g. B. flashing red and yellow alternately. This can also result in significantly perceptible patterns for the user. It is also possible for at least one lamp to continuously emit light in a time interval while at least one other lamp is flashing.

As a special example, the impression of a "circular color window" can arise in that neighboring lamps in each case assume one color one after the other, while other lamps in particular otherwise light up in a different color or not at all.

Several other states can be indicated by the lamps. If several further states are indicated by the lamps, the further states are preferably indicated in a different way by the lamps. As a result, the user receives feedback as to which status the security system is aware of.

The lighting means are preferably controlled in order to indicate the presence of a fire alarm signal. The further state of the security system, which is indicated by the lighting means that can be controlled in groups, can therefore be the state of a security system in which a fire alarm signal is present. For this purpose, a fire detector can transmit a fire alarm signal to the security system.

The lighting means can be controlled when the actuating element has been actuated, in particular in order to unlock the door lock. The further state of the security system, which is indicated by the lighting means that can be controlled in groups, can therefore be the state of a security system in which an actuating element has been actuated. The presence of a fire alarm signal and the presence of a completed actuation of the actuating element are preferably displayed in different ways by the lighting means.

The lamps can be controlled if a central emergency button of the security system has been pressed to unlock the door lock. The actuation of the central emergency button is preferably displayed in a different way than the presence of the fire alarm signal and/or the presence of a successful actuation of the actuating element by the lighting means.

The triggering element can be brought into a deactivated state. If the triggering element is actuated in the deactivated state, the triggering element does not cause unlocking of the door lock. The deactivated state can be caused by the lamps are displayed. The further state of the security system, which is indicated by the lighting means that can be controlled in groups, can therefore be the deactivated state. It is conceivable that a parameterization program can be used to set the lighting means not to display the deactivated state. This is particularly advantageous in a psychiatric ward.

The illuminants may serve to indicate a time progression duration. Specifically, the time progression duration is a countdown. The countdown can be determined using a timer, in particular using a timer of the triggering element.

The time progress duration can be e.g. B. be a predetermined period of time, after which a re-locking of the door lock is automatically initiated. This is particularly possible if there is no dangerous situation. The further state of the security system, which is indicated by the lighting means that can be controlled in groups, can thus be the time span from unlocking to automatic relocking. With regard to the time period, a distinction can be made between a predetermined short time period and a predetermined long time period. The actuation of the illuminants for the short period of time can differ from the actuation of the illuminants for the long period of time.

The time progress period can also be a predetermined period of time in which the automatic relocking has failed and an alarm is therefore issued in this predetermined period of time. Thus, the further state of the security system, which is displayed by the lighting means that can be controlled in groups, can be the period of time of the failed re-locking, in which an alarm is output. The alarm can be a pre-alarm and/or a main alarm. The lighting means can be controlled differently in the case of a pre-alarm than in the case of a main alarm.

It is conceivable that when the triggering element is actuated, the door lock is transferred from the locked to the unlocked state with a time delay. The lighting means can be controlled in such a way that the progression of the time delay is indicated by the lighting means. The further state of the security system, which is indicated by the lighting means that can be controlled in groups, can therefore be the state of a security system with time-delayed unlocking. The length of the time delay is called the delay time. Thus, the time advance duration can correspond to the delay duration.

In the delay period, both a first delay period that must elapse before the door lock is converted to the unlocked state and/or a second delay period that must elapse before the door lock is converted to the unlocked state can be visually displayed by the lighting means . As a result of an actuation of the trigger element, the actuation of a locking mechanism of the door lock for unlocking can be delayed by a first delay period. A delay action by an operator, in particular the operation of a delay element, within the first delay time period can cause the delay in activation of the locking mechanism to be lengthened by a second delay time period. The delaying action can be carried out in particular at a central escape route control. The delay element can be part of the central escape route control of the security system.

For example, as the time progression duration progresses, in particular the predetermined time period, the predetermined time period and/or the first and/or second delay time period, an increasing or decreasing number of lamps can light up in a first color. The remaining light sources can, in particular, light up in a second color or not. The glow may be continuous light emission or blinking.

In the event that as the duration of the progression of time progresses, in particular the predetermined period of time, the predetermined period of time and/or the first and/or second delay period, a decreasing number of lamps light up in a first color, it is conceivable that the lamps are controlled in such a way that at the end of the time progression period, the last illuminant still emitting the first color stops emitting light or switches to the second color.

In the event that an increasing number of lamps light up in a first color as the time progresses, it is conceivable that the lamps are controlled in such a way that at the end of the time progression the last lamp not yet emitting the first color begins to emit light in the first color or switched to light emission of the first color.

It may be the case that during the time progression period, in particular the predetermined period of time, the predetermined period of time, the first and/or second delay period, each illuminant is activated exactly once in order to start light emission in the first color or to start light emission in the first color until to end at the end of the time progression duration. In the event that a decreasing number of illuminants light up as the time progress duration progresses, each illuminant can in particular be activated exactly once in order to end light emission in the first color by the end of the time progress duration. In the event that an increasing number of illuminants light up in the first color as the time delay progresses, each illuminant can in particular be activated exactly once in order to start light emission in the first color. The duration of the progression of time thus corresponds to a one-time passage through the illuminants. In the case of a circular arrangement of the lamps, the duration of the progression of time corresponds exactly to one revolution of the lamps. The user receives feedback as to how far the time progression has progressed. It is conceivable that each light source is activated at a different point in time for this purpose. As a result, a time segment of the duration of the progression of time is represented by each individual light source. The one-time activation during the time progress period to start or end the emission in the first color does not preclude that each lamp can be activated multiple times in order to emit light of the first color, be it that the lamp emits light of the first color flashing or that the illuminants are activated in rapid succession for the short-term interruption of light emission. In the second case, the impression of a downcounter arises at least once, preferably several times, during the time progression period, in that the lamps are briefly switched off one after the other and then switched on again. Thus, the visual representation of the time progress duration may be repeatedly interrupted by a pattern symbolizing a passage of time.

As an alternative to lighting up an increasing or decreasing number of lamps, the duration of the progression of time can be represented by lighting up lamps in the first color one after the other. In particular, one lamp in each case lights up in the first color, while the other lamps light up in a second color or not at all. In a particularly preferred manner, each illuminant only lights up in the first color during a single time segment of the duration of the progression of time. The duration of the progression of time thus corresponds to a one-time passage through the illuminants. In the case of a circular arrangement of the lamps, the duration of the progression of time corresponds exactly to one revolution of the lamps. The user receives feedback as to how far the time progression has progressed.

The lighting means are preferably activated during the progression of time, in particular the predetermined time period, the predetermined time period, the first and/or second delay time period, in particular at regular time intervals. Thus, the time progress duration is displayed in a linear manner.

The predetermined time period, the predetermined time period, the first and/or second delay time period can each be represented differently. So u. a. the first color can be chosen differently for different time advance durations.

The time advance duration, in particular the predetermined time span, the predetermined time duration, the first and/or second delay time duration, can preferably be set by an operator. In particular, the operator can set the time advance duration through the parameterization program. The activation of the lighting means is preferably adapted to the set time progression duration. In particular, the time intervals at which the lamps are activated are adapted to the set time advance duration. The adaptation is particularly preferably carried out in such a way that at the end of the time progression period, the last illuminant not yet emitting the first light begins to emit light in the first color or the last illuminant still emitting the first light stops emitting light in the first color. The adaptation can take place in such a way that during the time progression period each luminous means is driven exactly once in order to start light emission in the first color or to end it for the time progression period. The adaptation can take place in such a way that the lighting means are activated at regular time intervals in particular.

In particular, provision is made for the lighting means to be activated in order to indicate an error in the security system. The further state of the safety system, which is indicated by the lighting means that can be controlled in groups, can therefore be the state of a safety system that is faulty.

The error may be that a component of the security system is inoperable, defective, failed, intentionally turned off, or removed. At least one of these errors for at least one component of the security system can be indicated by the light source. The component of the safety system may be a control device, a door lock or a part of the control device, the door lock and/or the triggering element, e.g. the trigger element processing unit. Additionally or alternatively, the error can be that the security system has a signal that a component connected to the security system, e.g. B. an alarm system is not operational, defective, failed, deliberately switched off or removed. At least one of these errors for at least one component connected to the security system can be indicated by the lighting means. A number of the faults mentioned can preferably be displayed by the lighting means. Different types of activation of the lighting means are preferably provided for different faults. Thus, different errors are displayed in different ways by the lighting means. The mistake or mistakes can in different ways to indicate a dangerous situation, e.g. B. the presence of a fire alarm signal or the actuation of the trigger element.

It may be that the triggering element, in particular the emergency button, comprises at least three triggering element processing units, in particular emergency button processing units. A first trigger element processing unit can be embodied as a first emergency button processing unit. A second triggering element processing unit can be designed as a second emergency button processing unit. A third triggering element processing unit can be designed as a third emergency button processing unit. The first, second and third trigger element processing units may each comprise a processor. The first and second trigger element processing units may each include at least one non-volatile memory. The third trigger element processing unit may include non-volatile memory and/or have access to non-volatile memory. For example, each of the first, second, and third trigger processing units may be a microprocessor or microcontroller.

The first and the second trigger element processing units can be used to detect the actuation signal. At least two actuating signals are preferably generated by actuating the actuating element. For this z. B. at least two circuits open. The first and the second trigger element processing unit can each independently detect an actuation signal. In this case, the first triggering element processing unit detects a first actuation signal and the second triggering element processing unit detects a second actuation signal. The first and the second trigger element processing unit can thereupon in each case independently trigger the activation of a door locking mechanism for unlocking. The first and the second trigger element processing unit each independently detect an actuation signal. Because the first and the second trigger element processing units detect the actuation signal independently of one another, there is redundancy with regard to the unlocking of the door after the trigger element has been actuated.

It is conceivable that the triggering element includes an acoustic alarm. The acoustic alarm can, for. B. serve to issue an alarm if the trigger element was actuated and / or after receiving a fire alarm signal.

It is possible that the activation of the acoustic alarm device and/or the lamps is redundant. It is conceivable that the third trigger element processing unit controls the acoustic alarm and/or the lighting means.

Provision can be made for the brightness of the lighting means to be adjustable to the ambient brightness. In particular, the brightness of the lamps can decrease when the ambient brightness decreases. This can prevent the user from being bothered by excessive brightness. In particular, a brightness sensor can be provided to adapt to the ambient brightness in order to detect the ambient brightness. Depending on the detection of the ambient brightness, the brightness of the lamps can be adjusted. Alternatively or additionally, predetermined periods of time and brightnesses correlated therewith for the lighting means can be stored in a non-volatile memory of the security system. The brightness for different times of the day and night can be specified by the specified periods of time.

The triggering element, in particular the emergency button, preferably comprises a light guide. The light guide can serve to guide the light emitted by the lighting means in the direction of the surface of the triggering element that is visible to the user. The light emitted by illuminants can be made visible to the user in a particularly pleasing way by means of the light guide.

The light guide is preferably designed in such a way that the different activation of the at least two groups of light sources is visible to the user. For this purpose in particular, the light guide can have light guide areas that are assigned to each group of light sources. If lighting means can be controlled individually, a light guide area can be assigned to each lighting means that can be controlled individually. Each light source can particularly preferably be controlled individually and each light source is assigned a light guide area.

Provision can be made for light beams emitted by one of the lighting means to be guided essentially only in the light guide area assigned to the respective lighting means. The surface of the light guide that is visible to the user can be perceived at least divided into luminous areas. Each light guide area can include a luminous area. Emission of light from a lighting means preferably results essentially only in the lighting of the associated lighting area. The lighting means are located in the center below the lighting areas, in particular in the direction of the surface of the triggering element.

It is conceivable that all luminous areas have the same surface area. The luminous areas can be mentally divided by a straight line. This allows the light areas z. B. beam-like shine.

Additionally or alternatively, the surface of the light guide that is visible to the user can be designed, for example, as a circular ring. The luminous areas can, in particular, each correspond to a sector of the circular ring.

It is conceivable that gaps are provided between the light guide areas. The cutouts in the light guide are provided so that the light sources, which can be controlled differently, cannot be routed from one light guide area to the other. The recesses are located between the groups of light sources, in particular the individual light sources. The light guide areas are located in the direction of the surface of the triggering element above the lighting means.

Preferably, the light guide areas each include a spreading section. The expanding section can be used to spread the light emitted by the associated illuminant. As a result, the emitted light can be distributed over the associated lighting area. The spreading section can in a projection z. B. in the shape of a trapezoid, in particular in the shape of an isosceles trapezium.

Additionally or alternatively, the expanding section can expand in a longitudinal section. As a result, the lighting area can be widened.

The area of the spread-apart end of the spread-apart section corresponds in particular to the luminous area in terms of size and/or shape. As a result, the emitted light can be distributed particularly well over the associated lighting area.

The expanding section is preferably arranged in the direction of the surface of the triggering element above the lighting means. As a result, the light emitted by the lamps reaches the light guide particularly well.

Provision is preferably made for the light guide area to have a transmission section for light transmission, with the light from the lighting means being able to be conducted through the transmission section to the spreading section. The forwarding section is thus arranged between the expanding section and the associated illuminant. The forwarding section serves to forward the light emitted by the illuminant to the spreading section. The forwarding section can spread at least less than the spreading section. The forwarding section can thus have edges that are parallel to one another in the direction of the light guide. The forwarding section may be provided when the light guide is a plate, e.g. B. the mounting plate or a circuit board, protrudes. Since the spreading section begins near the lighting area due to the forwarding section, the light guide can have a small space requirement at the height of the plate to be projected through. Thus, the stability of the plate can be guaranteed.

The light guide is preferably designed in one piece. The light guide can also be made of the same material. The light guide is particularly preferably designed as a monolith. The light guide is made in particular from translucent material.

The light guide area can have a connection section. The connecting section can be used to connect the light guide areas to one another. In particular, the connection areas of the light guide areas merge into one another in one piece, particularly preferably monolithically. The light from the lighting means can preferably be guided through the expanding section to the connecting section. In this way, the connecting section can join the expanding section in the direction of the light guide. The connection portion may include the luminous area. The connection areas together can comprise the surface facing the user.

The connecting section can have a depth of 2 mm to 6 mm, preferably 3 mm to 5 mm, particularly preferably 3.5 mm to 4.5 mm. As a result, the recesses are designed to be particularly deep, so that the light guide areas are separated to a particularly large extent. Thus essentially only the lighting area is illuminated by the associated lighting means. The depth of the connecting section nevertheless enables a mechanically stable, one-piece light guide.

The surface of the light guide that is visible to the user can be flat. Alternatively, the surface of the light guide that is visible to the user can be concave.

It is conceivable that the light guide surrounds the actuating element. For example, the light guide and the actuating element can be arranged concentrically with one another. The light guide, the actuator z. B. ring-shaped.

Alternatively, the light guide may be partially located within the actuator and/or the front face of the actuator may cover the light guide from the user's perspective. In this case, the front surface of the actuating element is preferably transparent or translucent where the light guide is covered.

Provision is preferably made for the light guide to have a contact surface for the actuating element. The contact surface can hold the actuating element in a form-fitting manner, in particular against an actuating direction. It may be that the restoring means presses the actuating element against the contact surface. The triggering element can have a cover.

The light guide can be fixed within the trigger element. In particular, the light guide can be attached to a mounting plate. The mounting plate can be used to attach the release element to a flush-mounted socket and/or a surface-mounted housing.

The light guide can have a flange with which the light guide is fixed within the trigger element. For example, the flange can be attached to the mounting plate. Due to the fact that the light guide itself is fastened within the triggering element, the light guide can reliably hold the actuating element against the direction of actuation with the contact surface. In particular, the hold is retained even when the cover of the triggering element is removed. The fastening means, which are used to fasten the flange to the mounting plate, can particularly preferably include at least one further component, e.g. B. connect a circuit board to the mounting plate.

An illuminating area is preferably formed in the center of the front surface of the operating member. The illuminating area is translucent and can be illuminated by a light source located behind it.

Provision can be made for the front surface of the actuating element to be partially conical. A crest of the front surface can be formed as the light-transmitting illuminating area. Due to the conical design, the illuminating area of the actuating element can be clearly visible from all sides. This applies in particular if the light-transmitting illuminating area protrudes beyond the cover. The overhang occurs in the opposite direction to the direction of actuation. The illuminating area is illuminated by a light source. It is conceivable that a front surface of the actuating element, in particular the illuminating area, protrudes at most 10 mm, preferably at most 7 mm, particularly preferably at most 5 mm above the light guide. As a result, the light guide is also clearly visible to users standing at an angle in front of the triggering element.

The front surface of the operating member may be partially concave. In particular, the front face can be conical around the illuminating area. On the other hand, an area of the front surface that covers the light guide can be concave.

The lighting means can preferably be controlled in such a way that lighting means lying opposite one another emit the same optical signal. As a result, users who are standing at an angle in front of the triggering element and for whom part of the lighting areas are covered by the actuating element can also see the lighting pattern. Opposite lighting means are understood to mean, in particular, lighting means which can be connected to one another by a straight line passing through a center of symmetry of the lighting means arrangement. The same optical signal is understood to mean, in particular, the emission of the same color and/or the same frequency when the lamp is flashing.

Additionally or alternatively, illuminants arranged in a mirror-inverted manner can emit the same optical signal. The mirror plane is preferably placed through the center of symmetry. The emission of the same optical signal for lamps located opposite one another and/or mirror-symmetrical lamps is conceivable for at least one further state of the security system, in particular for states other than the predetermined time period, the predetermined time period and/or the first and/or the second delay period. For example, it can be the presence of a fire alarm signal and/or a previously performed actuation of the actuating element and/or sabotage of the triggering element.

The triggering element can have an at least partially transparent covering means. The covering means can cover the actuating element, so that the actuating element can be actuated via the covering means.

The actuating element can preferably only be actuated via the covering means. For this purpose, the covering means can be arranged in particular in a non-removable manner in the triggering element. For example, the covering means can be permanently connected to the actuating element. The covering means can additionally or alternatively be mounted in a non-removable manner in the triggering element or in a housing in which the triggering element is arranged, or on a fastening plate to which the triggering element is fastened.

The covering means eliminates the need to adapt the actuating element to the haptic needs of the user. Thus, the actuator z. B. be adapted by the conical shape of the best perception possibility of the light emitted over the Illuminierbereich. The actuating element does not have to protrude far beyond the cover and/or the light guide. This can take over the covering means.

It may be that an actuation surface of the covering means is formed at a distance from the front surface of the actuation element that faces the actuation surface. Thus, an actuating surface spaced apart from the front surface, e.g. B. to a larger operating path, i.e. to a larger distance between the starting position and the operating position of the operating element and / or contribute to an operation with a flat hand.

In the starting position, the actuating surface of the covering means can protrude beyond the cover of the triggering element in such a way that the distance between the starting position and the actuating position in the direction of actuation corresponds at most to the distance between the actuating surface, in particular an elevation of the actuating surface, and the cover. As a result, the triggering element can be actuated with the palm of your hand.

It is conceivable that the covering means is shaped and transparent in such a way that the light guide is visible through the covering means. The light guide can thus be visible through the covering means spaced apart from the front surface, in particular when viewed from the front or at an angle.

The light guide preferably closes essentially flat with the cover. Thus the light guide can deviate from a planar termination with the cover by a maximum of ±3 mm, preferably a maximum of ±2 mm, particularly preferably a maximum of ±1 mm.

The object is also achieved by a safety system with a triggering element according to the invention. The triggering element according to the invention, in particular the emergency button according to the invention, can be designed as described in the description, the drawings and/or the claims.

The security system is used in particular to secure escape routes. The safety system thus serves to release the escape route. i.e. actuation of the actuating element leads to unlocking without authentication of the user. Unlocking can be immediate or delayed. A user can be anyone who uses the security system. For example, a user can B. be a guest who wants to escape through the door secured by the security system.

The security system may include door locking. The door latch may include a latch mechanism.

The locking mechanism can e.g. B. be formed electromechanically or purely electromagnetically. The locking mechanism includes z. B. at least one coil. Activation of the locking mechanism for locking or unlocking can be implemented in particular by switching an electrical power supply on or off. The electrical power supply can be used to supply the coil with electrical current.

An electromagnetic locking mechanism is exemplified in US Pat DE100 50 111 C1 described. In the unlocked state z. B. no magnetic forces on the door. In the locked state z. B. magnetic forces on a door.

An electromechanical locking mechanism has a mechanical connection to the door when locked. In the unlocked state, the mechanical connection can be canceled or canceled.

So the electromechanical locking mechanism z. B. have a locking element, ie a bolt or a door latch, which is in the unlocked state of the door lock in a retracted position. In the withdrawn Position is the locking element disengaged from the door. In the locked state, the latch member is engaged with the door. In a further alternative of an electromechanical locking mechanism, the locking mechanism is constructed in the manner of a door opener. i.e. the locking mechanism includes a latch member. In the locked state of the door lock, a door latch of the door is engaged with the locking mechanism. In the unlocked state, the latch element releases the door latch in such a way that the door latch, in particular by pressure on the door, can disengage from the locking mechanism.

Switching off the electrical power supply preferably leads to an unlocked state of the door lock. The locking mechanism for unlocking the door lock is thus activated by switching off the electrical power supply. Switching on the electrical power supply preferably leads to a locked state of the door lock. Thus, the control of the locking mechanism for locking is implemented by switching on the electrical power supply.

Alternatively, the safety system can be designed without the locking mechanism. In this case, the safety system only controls the locking mechanism. For example, the security system turns on or off the electrical power supply to the locking mechanism, or causes the electrical power supply to be turned on or off.

An "actuation for locking or unlocking" also occurs when the security system receives feedback on the status of the locking mechanism. "Triggering to lock or unlock" also occurs when, as detected by the feedback, the locking mechanism does not conform to the target state and therefore an alarm is issued and/or another attempt is made to reach the target state .

The security system may include a door lock controller. If a door locking control is provided, the door locking control preferably controls the locking mechanism. To do this, the door lock controller can switch the electrical power supply for the locking mechanism on and off.

The door lock may include the door lock controller.

As an alternative to the security system including the door latch, the security system may include the door latch controller but not the latch mechanism. In this case, the door locking control is designed as a door locking adapter. The door lock adapter is used to use the security system according to the invention with locking mechanisms that have already been installed.

The door locking controller and the triggering element are preferably connected to a first bus system. A connection to a bus system is understood below to mean a direct connection, so that a component connected to the bus system is to be regarded as a bus system participant with its own bus address. The door locking controller and the triggering element are connected to one another via the first bus system.

The triggering element can directly control the locking mechanism for unlocking. Alternatively and particularly preferably, the triggering element triggers activation of the locking mechanism for unlocking. Initiating a control is in particular sending a message, e.g. B. on the first bus system, understood that contains information and / or a command that causes the direct or indirect recipient of the message to make the control. The sender of the message initiates the activation. Initiating a triggering is thus understood to mean an indirect triggering. So e.g. B. send the triggering element a message via the first bus system to the door lock controller, whereupon the door lock controller controls the locking mechanism for unlocking. The triggering element can in particular cause the unlocking of the locking mechanism with a time delay.

The security system can be designed in such a way that, in addition to the unlocked and/or locked state of the door lock, if there is a further state of the security system, the lamps can be controlled to display the further state, with the further state being selectable by an operator of the security system. It is thus conceivable that not only the manner in which the lighting means are activated, but also the state in which the lighting means are activated can be set by the operator. In particular, a color to be emitted by the lighting means and/or a color pattern can be reserved for the setting. For example, the emission of green and red light by all light sources for the locked and the unlocked state can be permanently specified. However, the operator can choose in which state of the safety system at least some of the lamps emit blue light. For example, the operator can set that in the deactivated state of the triggering element, the lighting means of the relevant triggering element emit blue light. In particular, the setting can be made via the mobile communication device, in particular a cell phone. The mobile communication device can communicate with a radio module of the triggering element.

It is preferably provided that several door locks can be assigned to the trigger element, so that actuation of the trigger element triggers a triggering of a number of door locks, it being possible to set in the security system whether the lamps display a locked state until all the door locks assigned to the trigger element are unlocked , or whether the lamps only display a locked state until at least one of the door locks assigned to the triggering element is unlocked. The setting can, for example, via a switch, z. B. via a DIP switch. The door locks can B. each be provided for a stationary and a moving leaf of a door. The door should be able to be unlocked by actuating the release element. For this purpose, the door locks are actuated after actuation of the trigger element. Due to the adjustability, the operator can decide whether the lamps only have an unlocked state, e.g. by emitting a green light, when the full escape route width is available, i. H. the passive and active leaf are unlocked, or whether the lamps indicate an unlocked status when there is already an escape route through a door leaf. This setting option represents an inventive idea in itself, regardless of whether the lighting means can be controlled in at least two groups or not.

In particular with regard to the previous paragraph, it may be that several door locking controls are provided for a door, it being possible in the security system to set whether the door locking control immediately causes a locked state when the door locking control receives a signal to lock, independently of a within the signal received by the security system that at least part of the door is in an open position and the lamps indicate an unlocked state until all door locking controls for the door have established a locked state, or whether the door locking controls only initiate the locked state if there is at least one signal within the security system a fully closed position of the door and the lamps only indicate an unlocked condition if no door lock controls have established a locked condition.

The security system may include a controller. The control device is connected to the first bus system. The control device comprises at least digital processing electronics. The digital processing electronics can include at least one digital processing unit. The digital processing unit may include a processor and non-volatile memory. In particular, the digital processing electronics can comprise a first processing unit, a second processing unit and a third processing unit. The first, second and third processing units may each comprise a processor. The first, the second and the third processing unit can each be in the form of a microprocessor or microcontroller. The first, second and third processing units may each include non-volatile memory. In addition, the third processing unit in particular can have access to a non-volatile memory.

The control device can be integrated in the trigger element or the door lock control. In other words, the trigger element or the door lock control can comprise the control device. Alternatively, the control device can be connected to the triggering element and the door locking controller via a bus system, in particular via a first bus system.

If the control device is integrated in the triggering element, the third triggering element processing unit, in particular, serves at the same time as the third processing unit of the control device. In particular, the first triggering element processing unit can serve as the first processing unit of the control device and the second triggering element processing unit can serve as the second processing unit of the control device.

The change in the status of the door lock is preferably only displayed by the lighting means after the door lock controller has sent a corresponding signal to the triggering element and/or the control device via the bus system.

1. i. um den entriegelten Zustand und den verriegelten Zustand optisch darzustellen,
2. ii. um eine zeitverzögerte Ansteuerung des Türverriegelungsmechanismus, insbesondere zur Entriegelung und insbesondere nach Betätigung des Auslöseelements optisch darzustellen,
3. iii. um einen Alarmzustand insbesondere nach einer Betätigung des Auslöseelements oder nach Empfang eines Brandmeldesignals optisch darzustellen und/oder
4. iv. um einen optischen Alarm auszugeben, falls eine Wiederverriegelung fehlschlägt, insbesondere die Tür geöffnet bleibt, was über eine Türzustandsüberwachungsvorrichtung detektierbar ist,

The control device preferably causes the lighting means to be activated. If the control device and the triggering element are connected to one another via the first bus system, the control device can cause the triggering element to control the lighting means,

1. i. to visually represent the unlocked state and the locked state,
2. ii. to visually display a time-delayed actuation of the door locking mechanism, in particular for unlocking and in particular after actuation of the trigger element,
3. iii. to visually display an alarm condition, in particular after the triggering element has been actuated or after a fire alarm signal has been received, and/or
4. IV. to issue a visual alarm if relocking fails, in particular if the door remains open, which can be detected via a door status monitoring device,

It may be that in at least one of the above cases the control device i. to iv. causes the trigger element to control the lamps. The control device preferably initiates in several, particularly preferably in all, of the above cases i. to iv. the trigger element to control the lamps. For this purpose, parameters are stored in particular in the control device, in which way and way in which case the light sources are to be controlled. The processing electronics, in particular the third processing unit, can communicate with the electronics unit, in particular the third triggering element processing unit, via the first bus system and thus initiate the actuation.

The control device can be connected or can be connected to a second bus system. A control center of the security system, in particular a security device, a central escape route control and/or a multi-door display device, can be connected to the second bus system. The control device is used to route or forward messages to the control center or to receive or forward messages from the control center.

The control device can be designed in particular to initiate non-safety-related locking or unlocking.

Thus, the control device can control the door locking mechanism for unlocking after receiving a positive authentication signal or cause such a control. For this purpose, the control device can be connected or can be connected to an access control system.

The control device can, for. B. control the door locking mechanism for unlocking at a predetermined time or cause such a control. The unlocking at a predetermined time can be provided if z. B. the door should be unlocked in a time window per day.

If there is no danger, i .e. if neither the triggering element was actuated nor is there a fire alarm signal, the control device can activate the door locking mechanism for automatic relocking after the predetermined period of time has elapsed, or can initiate such an activation. In addition, it can be provided that the control device activates the locking mechanism for automatic relocking immediately after receiving a signal about a closed state of the door or initiates such an activation. The closed state of the door can be detected by at least one door state monitoring device.

Particularly preferably, the safety system, in particular the control device, prevents activation of a further door locking mechanism after activation of a first door locking mechanism until a condition is present such that a lock is formed. For example, a first door at an entrance to a Room and a second door can be arranged at an exit of the same room. The security system, in particular the control device, z. B. cause an unlocking of the door lock of the first door in the presence of a positive authentication signal for a door lock of the first door. Even if a positive authentication signal for the door lock of the second door is present to the security system, in particular the control device, the security system, in particular the control device, can prevent the unlocking of the door lock of the second door until a condition is present. If the condition is present, the safety system, in particular the control device, causes the door lock of the second door to be unlocked.

Until the condition is met, the lighting means can indicate that the actuation of the further door locking mechanism is prevented. In this way, the user receives in particular the feedback that the lack of a positive authentication signal does not prevent the unlocking of the second door.

Which functions the security system can perform can depend on a communication module. Depending on the communication module used, more or fewer functions can be executable by the security system. The communication module is arranged in particular in a receptacle of the security system. Functions of the security system can be activated in particular by the arrangement in the receptacle, so that the security system can carry out the functions.

It is conceivable that, in particular when the security system is put into operation, the lighting means display the status of individual components of the security system. It is conceivable that lighting means are permanently assigned to the individual components. The status of the components can be displayed simultaneously. Thus, the operator can quickly get an overview of the commissioning. The components can be the door lock, the door lock controller, the triggering element, the control device or parts of the triggering element or the control device, such as inputs and/or outputs of a processing unit and/or a triggering element processing unit. The inputs and/or outputs can be the connection to the first bus system, to a second bus system, to a bus input via which authentication of an authorized user is communicated, to the input of a key switch and/or the like.

It is conceivable that the security system has a number of triggering elements and/or a number of door locking controls. The multiple triggering elements and/or the multiple door locking controls can be connected to the first bus system.

The lighting means can display the status of the multiple triggering elements and/or multiple door locking controls, in particular at the same time. It is conceivable that at least one lamp is permanently assigned to one of the triggering elements and/or one of the door locking controls. The display can take place in particular when the security system is started up.

It is conceivable that the lighting means can represent which functions the control device can perform. In particular, the communication module used can be displayed by the lighting means. Which functions can be executed can be displayed in particular when the safety system is put into operation.

It may be that when the security system is put into operation, the lamps are activated one after the other in order to display the status of the components or the executable functions of the security system. As a result, each lamp can be assigned several states and/or functions to be displayed. The number of states and/or functions displayed can therefore exceed the number of lamps. For example, the states of the triggering elements and the door locking controls can be displayed first, then the states of the inputs and outputs and then the executable functions by displaying the communication module used. A different sequence can of course also be selected. The activation of the lighting means, which is used to display the status of the components or the executable functions of the control device one after the other, can therefore include at least one further activation of the lighting means, at least in addition to a first activation. The further actuation of the lighting means can take place after a predetermined time lapse or alternatively after a conscious action.

Overall, it may be the case that, particularly when the security system is commissioned, the lighting means can be controlled in such a way that the lighting means indicate the ability to carry out at least one function of the control device and/or the status of a component, in particular the door locking control or the door locking controls and/or the triggering element or the Show trigger elements, in particular lamps are permanently assigned to a door lock control and / or a trigger element.

It is preferably stored in an electronic memory of the security system in an adjustable manner in which way the lighting means are to be controlled as a function of the state of the door lock. The electronic memory can be a non-volatile memory of the triggering element processing unit and/or a act processing unit. The manner of activation can include a flashing frequency, a color selection and/or a color pattern. It can be adjustable whether a predetermined period of time is to be displayed without blinking. In particular, the setting can be made via the mobile communication device, in particular a cell phone. The mobile communication device can communicate with the radio module.

In the following, a distinction is made between a user and an operator. A user can be anyone who uses the security system 1 . For example, a user can B. be a guest who wants to escape through the door secured by the security system 1. An operator is used to operate the security system 1. The operator can z. B. to authenticate against the security system. For example, the operator can B. Be a member of a security guard. The operator can particularly preferably set the safety system 1 .

In the following, the term "actuation of the emergency button" means "actuation of the actuating element of the emergency button".

A connection to a bus system is understood below to mean a direct connection, so that a component connected to the bus system is to be regarded as a bus system participant with its own bus address.

Initiating an activation is understood in particular as meaning the sending of a message via a first and/or second bus system, which message contains information and/or a command which causes the direct or indirect recipient of the message to carry out the activation. The sender of the message initiates the activation. Initiating a triggering is thus understood to mean an indirect triggering. In particular, the message can correspond to a bus telegram.

As a result of an operation means that an operation is the cause, regardless of whether the operation continues or not.

In the figures 1 and 2 a first exemplary embodiment of a security system 1 according to the invention for a door 2 is shown. The door 2 is not part of the safety system 1 according to the invention. The safety system 1 according to the invention comprises a door lock 200 and an emergency button 10. The emergency button 10 comprises a control device 100. A key switch 500 is assigned to the emergency button 10. The security system 1 can include the key switch 500 . Alternatively, the security system 1, in particular the emergency button 10, have a key switch input via which a connection to the key switch 500 can be established.

As in figure 2 shown, the emergency button 10 and the door lock 200 are connected to one another via a first bus system 400 . The key switch 500 is electrically connected or connectable to the emergency button 10 via a connection 402 . The connection 402 is shown as a dashed arrow to show that signals about a position of a key inserted into the key switch 500 are fed to an electronic unit 24 of the emergency switch 10 . As an alternative to the connection 402, the key switch 500 can also be connected to the first bus system 400 (not shown). This alternative applies to all exemplary embodiments.

The emergency button 10 is designed to send a message to the door lock 200 as a result of an actuation of the emergency button 10 via the first bus system 400 and thereby to cause the door lock to be unlocked. The message as a result of pressing the emergency button 10 can be delayed.

The security system 1 according to the invention, in particular the emergency button 10, can also be connectable to a fire alarm (not shown). If a fire alarm signal is present, the security system 1 also causes the door lock 200 to be unlocked.

The control device 100 does not carry out safety-related functions: The control device 100 can thus cause the door lock 200 to be unlocked for authorized persons. For this purpose, the control device 100 can be connected to an access control system (not shown). In particular, the access control system can be connected or can be connected to the first bus system 400 . The control device 100 receives from the access control system, in particular via the bus system 400, a positive authentication signal about the authentication that has taken place. Thereafter, the control device 100 causes an unlocking of the door lock 200. The access control system can, for. B. a reader, a key switch, a keyboard for entering a code or a lock cylinder of a mechanical lock, in particular a self-locking panic lock, include or be designed in such a way.

Likewise, the control device 100 can automatically trigger an unlocking of the door lock 200 at a specified time or after a specified period of time, e.g. B. if the door should be unlocked in a time window per day.

If there is no danger, i .e. If neither the emergency button 10 has been actuated nor is there a fire alarm signal, the control device 100 can automatically initiate a re-locking after a predetermined period of time has elapsed. Here, in addition to the positive authentication signal, the control device 100 can also receive an access signal from the access control system and/or measure the length of the positive authentication signal. The control device 100 can adapt the length of the predetermined period of time by means of the access signal or based on the length of the authentication signal. For example, a person can B. hold an ID card in front of the reader for a long time or turn the key for a long time. This signals that the predetermined period of time should correspond to a long period of time previously stored in control device 100 . If the person holds the ID card briefly in front of the reader or if the user turns the key briefly, a signal is given that the predetermined period of time should correspond to a short period of time previously stored in the control device 100 .

A first door status monitor 204 and a second door status monitor 206 detect whether the door 2 is open or closed. The control device 100 receives at least indirectly a signal from the door status monitoring devices 204, 206. If the door lock 200 has been unlocked due to a positive authentication signal, the control device 100 can immediately and automatically cause the door lock 200 to be locked again as soon as the control device 100 with the aid of the door status monitoring devices 204, 206 the information is available that the door is first opened and now closed again.

The emergency button 10 includes an acoustic alarm device 23 and light source 41 (see also figure 13 ). The lamps 41 are used to display the locked or unlocked state of the door lock 200 and thus serve as a display device. The lamps 41 are used for the visual representation of a time-delayed unlocking of the door lock 200 as a result of an actuation of the emergency button 10 and thus serve as a display device. The lamps 41 are used for the visual representation of an alarm condition after receipt of the fire alarm signal or as a result of pressing the emergency button 10 and thus serve as a display. The lamps 41 are used for visual display when a previously described re-locking fails.

The control device 100 controls the acoustic alarm generator 23 in order to emit an acoustic alarm when there is a dangerous situation, ie when a Fire alarm signal received or emergency button 10 pressed. The control device 100 controls the acoustic alarm generator 23 in order to emit an acoustic alarm if re-locking fails.

The control device 100 controls the lamps 41 to display the locking or unlocking status of the door lock 200, to visually display a time-delayed unlocking and/or to emit a visual alarm when a fire alarm signal is received or the emergency button 10 has been actuated, or when relocking fails.

In the unlocked state of the door lock 200, the control device 100 can monitor the opening of the door with the aid of the door state monitoring devices 204, 206. If desired, the control device 100 can have an acoustic alarm emitted if the door 2 was opened while the door lock 200 was in the unlocked state, at least if there is no positive authentication signal. This way it can be monitored when someone opens the door, even if the door is unlocked.

The emergency button 10 can include at least one additional output. The control device 100 can use the output to control other components that can be connected to the security system 1 according to the invention, e.g. B. a room light.

The parameters for executing the named functions of the control device 100 are stored in the control device 100 . So are e.g. B. the predetermined time (s), the predetermined period of time (s), parameters for the audible alarms, e.g. B. in which volume with which frequency an acoustic alarm is to be output, and parameters for the different activations of the light sources 41 for visual representation of the different, above-mentioned states of the security system 1 are stored in the control device 100. The parameters for the light sources can include flashing frequencies, colors to be emitted, color intensities and/or lighting patterns. For parameterization, the control device 100 can communicate with a mobile communication device via a radio module 64 . Alternatively, the parameters can be set using a monitoring device 301 via a second bus system 401 (see Fig. Figures 9 and 10 ). A parameterization program is provided for parameterization, which runs on a communication device, e.g. B. a personal computer, a mobile phone and / or a tablet, executable. The operator can set the parameters using the parameterization program.

In figure 2 the structure of the door lock 200 and the emergency button 10 is shown in more detail.

The emergency button 10 has a first emergency button processing unit 20 , a second emergency button processing unit 21 and a third emergency button processing unit 22 . The first, the second and the third emergency button processing unit 20, 21, 22 are each designed as microprocessors or microcontrollers. The first and the second emergency button processing units 20, 21 comprise a non-volatile memory. The third emergency button processing unit 22 includes a non-volatile memory and/or has access to a non-volatile memory. The first, second and third emergency button processing unit 20, 21, 22 are collectively referred to as the electronic unit 24 of the emergency button 10.

Electronics unit 24 also serves as control device 100. First emergency button processing unit 20 serves as first processing unit 103 of control device 100. Second emergency button processing unit 21 serves as second processing unit 104 of control device 100. Third emergency button processing unit 22 serves as third processing unit 105 of control device 100.

The first and the second emergency button processing unit 20, 21 are used to carry out the safety-related functions of the emergency button. The third emergency button processing unit 22 or processing unit 105 is used to carry out the non-safety-related functions. One of the safety-relevant functions is the initiation of unlocking in the event of danger. The non-safety-related functions include the other functions listed above.

When the emergency button 10 is actuated, an actuating element 11 is moved from a starting position 11.I to an actuating position 11.II, whereby a switch 63 is actuated (see also figures 12 , 13 ). As a result, a first and a second actuation signal are generated. This opens a first and a second circuit (not shown). A first circuit opening signal is detected by the first emergency button processing unit 20 . A signal about the opening of the second circuit is detected by the second emergency button processing unit 21 . The actuation signal is understood to be the signal generated by the user by actuating the actuating element in order to unlock the door lock and release the escape route. The expression "as a result of an actuation of the emergency button 10" is used in particular in the sense of "after generation of the actuation signal", ie regardless of whether the actuation element 11 is still in the actuation position 11.II or has already returned to the starting position 11.I is.

The first emergency button processing unit 20 and the second emergency button processing unit 21 each cause an unlocking of the door lock 200 via the first bus system 400 after detecting the actuation signal. The second Emergency button processing unit 21 thus acts redundantly to the first emergency button processing unit 20.

The door lock 200 includes a door lock controller 201. The door lock controller 201 includes a first processing means 202 and a second processing means 203. The first and second processing means 202, 203 are referred to collectively as the electronic device 207. The first and the second processing means 202, 203 are each designed as a microprocessor or microcontroller. The first and the second processing means 202, 203 can each control a locking mechanism 205 of the door lock 200 for unlocking. In case of danger, i. H. as a result of the actuation of the emergency button 10 or after receiving a fire alarm signal, both the first processing means 202 and the second processing means 203 control the locking mechanism 205 for unlocking. The second processing means 203 is therefore redundant with respect to the first processing means 202. One-fault security is achieved with this structure.

The locking mechanism 205 is designed to be electromechanical. The locking mechanism 205 includes z. B. an electromechanically actuated case element (not shown), which locks a door latch of the door 2 in the locked state of the door lock 200 and in the unlocked state of the door lock 200 releases. When the locking mechanism 205 is activated for locking, the first and the second processing means 202, 203 switch on an electric current for the locking mechanism 205. When the locking mechanism 205 is activated for unlocking, the first and the second processing means 202, 203 switch off an electrical current for the locking mechanism 205. A separate switch is assigned to each processing means 202, 203 for this purpose. Opening just one of the switches will shut off power to the locking mechanism 205.

The door lock controller 201 receives feedback on the state of the lock mechanism 205 via an unillustrated lock mechanism state monitor. Specifically, a position of an armature of a coil of the lock mechanism 205 is monitored. If the status of the door lock 205 does not correspond to the desired status, an alarm is issued. In addition or as an alternative, a renewed attempt can be made in this case to reach the target state.

As a result of the emergency button 10 being actuated, the first and the second emergency button processing unit 20, 21 communicate with the first and the second processing means 202, 203 via the first bus system 400 with the aid of a message. The message can contain a notification of being actuated or a control command for unlocking. The first emergency button processing unit 20 informs the first processing means 202 and the second emergency button processing unit 21 informs the second processing means 203. With the message, the first and the second emergency button processing units 20, 21 cause both the first and the second processing means 202, 203 to activate the locking mechanism 205 trigger for unlocking, i.e. switch off the electric current.

The presence of a fire alarm signal is detected by the first and the second emergency button processing unit 20, 21. The first and the second emergency button processing unit 20, 21 then cause the locking mechanism 205 to be unlocked by the door locking control 201 by sending a message to the first and the second processing means 202, 203. The first emergency button processing unit 20 informs the first processing means 202 and the second emergency button processing unit 21 informs the second processing means 203. With the message, the first and the second emergency button processing units 20, 21 cause both the first and the second processing means 202, 203 to activate the locking mechanism 205 trigger for unlocking, i.e. switch off the electric current.

The actuation of the emergency button 10 or the presence of a fire alarm signal can be sent in a message from one of the two emergency button processing units 20, 21, with the first emergency button processing unit 20 writing a first part of the message and the second emergency button processing unit 21 writing a second part of the message. The first and the second processing means 202, 203 are each responsible for at least part of the message. The emergency button processing units 20, 21, 22 and the first and the second processing means 202, 203 can each receive messages via the first bus system 400. In this case, the electronic unit 24 and the door locking control 201 can each be assigned a bus address.

The first and the second emergency button processing units 20, 21 monitor each other. If an error is detected, the electronics unit 24, in particular the intact emergency button processing unit 20, 21, causes the first and the second processing means 202, 203 to activate the door locking mechanism 205 for unlocking. The first and second processing means 202, 203 monitor each other. If an error is detected, then at least the intact processing means 202, 203 actuates the locking mechanism 205 for unlocking. Likewise, if there is a fault in the bus system 400, the locking mechanism 205 is activated by the door locking controller 201 for unlocking. For this and to review the first and second Emergency button processing unit 20, 21, a sign-of-life signal from the first and second emergency button processing units 20, 21 is regularly sent to the door lock controller 201. If there is no sign-of-life signal, the first and second processing means 202, 203 actuate the locking mechanism 205 for unlocking. The first and the second processing means 202, 203 communicate with one another when the door lock controller 201 has received a message about the actuation of the emergency button 10 and/or the presence of a fire alarm signal. If only the first processing means 202 or the second processing means 203 determines that the emergency button 10 has been actuated or that a fire alarm signal is present, the determining processing means 202, 203 triggers the door locking mechanism 205 to unlock and initiates that the other processing means 202, 203 also release the Door locking mechanism 205 controls for unlocking. An error and a fault always include a failure of the respective component. In the event of a power failure, the locking mechanism 205 automatically switches to the unlocked state. In the processes described in this section, the security system 1 also emits an acoustic and/or visual alarm, in particular by means of the control device 100 .

If the actuation signal has been generated, it is electronically prevented that the door lock 200 is transferred into the locked state without the existence of a cancellation condition. This prevents the door from being locked while a hazardous condition persists. For this purpose, an electronic determination is integrated in the electronic device 207 . As a result of the actuation of the actuation element 11, which is used to release the escape route, the electronic determination is transferred to an actuation state. In the actuated state, the activation of the door lock 200 for locking is prevented.

The electronic statement includes a first program code. The first program code includes a first variable or has access to a first variable. In an initial state of the electronic determination, the first variable is set to an initial value. In the actuation state, the first variable is set to an actuation value which prevents the door lock 200 from being actuated to lock. The first variable can be binary. If the cancellation condition is met, the electronic determination is returned to an initial state. To do this, the value of the first variable is set to the initial value. In the initial state of the electronic determination, activation of the door lock 200 for locking is permitted. The first program code detects the first value of the first variable and allows the door lock 200 to be locked if the value of the first variable corresponds to the initial value, and prevents locking of the door lock 200 when the value of the first variable equals the actuation value.

The electronic determination is stored both in the first processing means 202 and redundantly in the second processing means 203. The first program code is stored in the first processing means 202 for this purpose. The first variable is stored in the non-volatile memory of the first processing means 202 . A second program code with the same functionality as the first program code is stored in the second processing means 203 . The first variable is redundantly stored in the non-volatile memory of the second processing means 203 .

The first variable is additionally stored in the first emergency button processing unit 20 and in the second emergency button processing unit 21 in the non-volatile memories. As a result of the actuation of the emergency button 10, the first variable in the first and in the second emergency button processing unit 20, 21 is converted from the initial value to the actuation value. The changed value of the first variable is transmitted to the electronic device 207 via the bus system 400 . The emergency button 10 repeatedly sends the actuation value of the first variable to the electronic device 207 until a cancellation condition is met. The sending can take place at regular time intervals, in particular together with the sign-of-life signal.

At least when at least one of the door status monitoring devices 204, 206 has detected that the door 2 was opened after the emergency button 10 was actuated, a cancellation action on the emergency button 10 is necessary to achieve the cancellation condition.

The actuating element 11 is non-latching. The actuating element 11 is transferred from the initial position 11.I to the actuating position 11.II when actuated (see Fig. figure 11 ). Immediately after actuation, the actuation element 11 moves back into the starting position 11.I by the force of a return means 12 designed as a spring (see Fig. figure 12 , 13 ). The actuating element 11 is actuated in a translatory manner.

The cancellation action on the emergency button 10 is carried out by actuating the actuating element 11 . This generates an override signal that corresponds to the actuation signal. In order for the control device 100 to be able to recognize whether an actuation of the emergency button 10 is used to unlock the door lock 200 or whether a cancellation action is present, another signal must be generated at the same time in order to achieve the cancellation condition. To do this, an operator authenticates himself. The authentication takes place by inserting and turning a key in the key switch 500. The activation of the activation element 11 and the authentication must overlap in time. i.e. the The operator must hold the key in the turned state while the operating element 11 is in the operating position 11.II. The actuator 11 must return to the home position 11.I while the key is in the turned state. The course of action is sufficient to achieve the cancellation condition.

If the door status monitoring devices 204, 206 have detected that the door 2 has remained permanently closed as a result of the actuation of the emergency button 10, the cancellation condition can be achieved in at least one other way, namely by the elapse of a predetermined time interval. So e.g. B. after 60 seconds after the last generation of the actuation signal, the cancellation condition can be reached if the door 2 has remained closed. In this case, authentication at the key switch 500 and cancellation action at the emergency button 10 are not necessary.

The first and the second door status monitoring devices 204, 206 are provided in order to detect with a one-fault certainty that the door 2 has remained permanently closed as a result of the actuation of the emergency button 10. For this purpose, the door status monitoring devices 204, 206 are preferably designed differently. The first door status monitor 204 may e.g. B. be designed as a door contact. The second door status monitoring device 206 can e.g. B. be designed as a trap contact. Alternatively, e.g. B. at least one of the door status monitors magnetically, z. B. as a reed switch, monitor the status of door 2. The door lock controller 201 receives a signal from the first and second door status monitors 204, 206, respectively, as to whether the door 2 is open or closed. Only if no door opening signal has been sent from either the first door status monitor 204 or the second door status monitor 206 during the predetermined time interval can the cancellation condition be achieved by the elapse of the predetermined time interval.

The door lock controller 201 includes a timer to measure the predetermined time interval. The door locking controller 201 starts the timer as a result of the emergency button 10 being actuated. If the door locking controller 201 receives a signal from the first or the second door status monitoring device 204, 206 during the predetermined time interval that the door has been opened, a cancellation action must be taken at the emergency button 10. In this case, the lapse of the predetermined time interval is not enough. The length of the predetermined time interval is stored in the door lock controller 201 .

The door lock controller 201 checks whether the cancellation condition is allowed to be reached by elapse of the predetermined time interval before the Door lock control 201 controls the locking mechanism 205 to lock. When starting up the security system 1, ie before the start of the operation of the security system 1, an operator can store whether the elapse of the predetermined time interval without opening the door 2 is permissible as a cancellation condition and thus leads to the door 2 being locked again. The deposit can be made in the emergency button 10. A check of the permissibility, an elapse of the predetermined time interval and an absence of a signal from the first and second door status monitors 204, 206 about opening of the door 2 is sufficient for the achievement of the cancellation condition.

Door locking controller 201 communicates the open or closed state of the door to emergency button 10 and/or to control device 100 via bus 400.

The electronics unit 24 includes a timer. A first delay period can be stored in the electronics unit 24 . If the door lock 200 is to be unlocked with a time delay, after the activation signal has been generated, the electronic unit 24 waits for the first delay time before the first and the second emergency button processing unit 20, 21 communicate with the door lock controller 201 via the first bus system 400 in order to initiate unlocking .

The third processing unit 105 causes the to figure 1 and 2 described non-safety unlocking and locking of the door lock 200, z. B. unlocking after receipt of the authentication signal, at a predetermined time or after a predetermined period of time or locking after a predetermined period of time or immediately after closing the door 2. For this purpose, the third processing unit 105 communicates via the first bus system 400 with the door lock controller 201. The communication can e.g. B. contain information or a control command that causes the door lock controller 201 to control the locking mechanism for unlocking or locking. If control device 100 is connected to the second bus system (see 7 ), the third processing unit 105 is used to forward messages from and/or to a central escape route controller 300.

The third emergency button processing unit 22 controls the acoustic alarm device 23 and the lighting means 41 .

If at least one of the processing means 202, 203 indicates that the locking mechanism 205 has assumed the unlocked state, the processing means 202, 203 sends a corresponding signal via the bus 400 to the Electronic unit 24. The electronic device 207 is connected or connectable to the door status monitoring devices 204, 206 and receives signals about an open or closed status of the door from the door status monitoring devices 204, 206.

The functions mentioned, which the control device 100, the door locking control 2021 and/or the emergency button 10 execute, can be executed with the aid of software modules. Program codes are stored in the electronic device 207 and/or the electronic unit 24, with the aid of which the functions can be executed.

figure 3 represents a variant of the in the figures 1 and 2 represented safety system 1. Here, the control device 100 is formed separately from the emergency button 10 and the door lock 200. The control device 100 can e.g. B. in a DIN rail housing (not shown) can be arranged. The control device 100 is not integrated in an emergency button 10 or in a door lock 200 . For example, the control device 100 can be provided for arrangement in a technical room. The first bus system 400 connects the control device 100, the door lock 200 and the emergency button 10 to one another. As in the first exemplary embodiment, the key switch 500 is electrically connected or can be connected to the emergency button 10 via a connection 402 .

Unless otherwise described, the structure and function corresponds to the first embodiment, with the functions belonging to the figures 1 and 2 are described with the aid of the control device 100 or the processing units 103, 104, 105, from the control device 100 of FIG figure 3 are executed and the functions belonging to the figures 1 and 2 are described with the help of the emergency button 10 or the emergency button processing units 20, 21, 22, are executed by the emergency button 10: In particular, the first and the second emergency button processing unit 20, 21 detect the actuation signal, communicate as a result of an actuation of the emergency button 10 with the first and the second processing means 202, 203 via the first bus system 400 and thus cause the locking mechanism 205 to be actuated by the door locking controller 201. The measures for achieving on-fault safety or redundancy are carried out with the aid of the first and the second emergency button processing units 20, 21. The first variable is stored in the first and the second emergency button processing unit 20, 21 and is transmitted from there to the door lock controller 201. The emergency button 10 includes the timer for determining the first delay period. The control device 100 is connected or can be connected to the second bus system 401 . The third processing unit 105 causes the to figure 1 and 2 described non-safety unlocking and locking of the door lock 200, z. B. unlocking after receiving the Authentication signal at a predetermined time or after a predetermined period of time or automatic re-locking after a predetermined period of time or immediately after closing the door 2.

The first, second and third processing units 103, 104, 105 are each designed as a microprocessor or microcontroller. The first, second and third processing units 103, 104, 105 together form processing electronics 101. The first and second processing units 103, 104 have a non-volatile memory. The third processing unit 105 comprises a non-volatile memory and/or has access to a non-volatile memory.

A fire alarm signal can be received both by the control device 100 and by the emergency button 10 . The presence of a fire alarm signal is detected by the first and the second emergency button processing unit 20, 21 for the emergency button 10 or by the first and the second processing unit 103, 104 for the control device 100. Accordingly, both the control device 100 with the aid of the first and the second processing unit 103, 104 and the emergency button 10 with the aid of the first and the second emergency button processing unit 20, 21 can cause the door lock 200 to be unlocked. For this purpose, communication takes place via the first bus system 400 with the door locking controller 201 .

The control device 100 is informed via the first bus system 400 when the emergency button 10 causes the door lock 200 to be unlocked, that is to say as a result of the emergency button 10 being actuated or after a fire alarm signal has been received. The control device 100 is also informed of a time-delayed unlocking of the door lock 200 as a result of the emergency button 10 being actuated. The control device 100 is informed of the locking and unlocking status of the door lock 200 . The control device 100 is informed of the open or closed state of the door 2 .

The control device 100 causes activation of the alarm device 23 and the light source 41 for the figures 1 and 2 described acoustic alarms and visual representations. For this purpose, the control device 100 can communicate with the electronic unit 24, in particular with the third emergency button processing unit 22, via the first bus system 400. The third emergency button processing unit 22 then controls the alarm device 23 or the lighting means 41 . For this purpose, the parameters for the alarm device 23 and the lighting means 41 are stored in the control device 100 .

In the embodiments of Figures 1 to 3 For example, door latch 200 includes door status monitors 204, 206. Alternatively, and not shown the door status monitoring devices 204, 206 can be connected to the first bus system 400 or directly to the emergency button 10 and/or the control device 100.

In the embodiments of Figures 1 to 3 At least one additional emergency button (not shown) can be connected to first bus system 400, which is configured without control device 100. The other emergency button is like the emergency button 10 in figure 3 formed and can cause the unlocking of the door lock 200 upon actuation. The additional emergency button corresponds to the emergency button 10 in terms of structure and functionality figure 3 .

In the embodiments of Figures 1 to 3 at least one further door lock (not shown) can be connected to the first bus system 400 . The further door lock is like the door lock 200 in figure 2 or 3 formed and can also be unlocked when the emergency button 10 is pressed. The other door lock corresponds to the structure and functionality of the door locks 200 of Figures 1 to 3 .

In figure 4 a third exemplary embodiment of a security system 1 according to the invention with a plurality of emergency buttons 10, 1010, 2010, 3010 is shown. The security system 1 includes several door locks 200, 1200, 2200, 3200. Each emergency button 10, 1010, 2010, 3010 is assigned a key switch 500, 1500, 2500, 3500. The security system 1 is used to arrange the emergency buttons 10, 1010, 2010, 3010 and door locks 200, 1200, 2200, 3200 on different doors 2, 2002, 3002. The doors 2, 2002, 3002 are not part of the security system 1 according to the invention. The several Emergency buttons 10, 1010, 2010, 3010 are connected to the first bus system 400 and thus correspond to a number of emergency buttons 10, 1010, 2010, 3010. The door locks 200, 1200, 2200, 3200 are connected to the first bus system 400 and thus correspond to one Number of door locks 200, 1200, 2200, 3200.

In the example of figure 4 the emergency buttons 10, 1010 are assigned to the door locks 200, 1200. The emergency button 2010 is assigned to the door lock 2200. The emergency button 3010 is assigned to the door lock 3200. As a result of an actuation of one of the emergency buttons 10, 1010, the two door locks 200, 1200 are unlocked, but not the door locks 2200, 3200. If the emergency button 2010 is actuated, only the door lock 2200 is unlocked. Accordingly, when the emergency button 3010 is pressed, only the door lock 3200 is unlocked. Thus, in this embodiment, the door latches 200, 1200, 2200, 3200 are selectively unlocked.

For example, the emergency buttons 10, 1010 can be provided for arrangement on a double-leaf door 2. One door lock 200, 1200 is on each door leaf 3, 4 to arrange the door 2. The emergency button 2010 and the door lock 2200 are intended to be arranged on another door 2002 . The emergency button 3020 and the door lock 3200 are to be arranged on a door 3002, as in figure 4 shown.

The security system 1 off figure 4 can also for from figure 4 deviating selective unlocking can be set. At one to figure 4 deviating exemplary setting, only one associated door lock 200, 1200, 2200, 3200 is unlocked when one of the emergency buttons 10,1010, 2010, 3010 is actuated. Thus, only one door lock 200, 1200, 2200, 3200 is assigned to each emergency button 10, 1010, 2010, 3010. In particular, a safety system 1 adjusted in this way is suitable for four single-leaf doors, each with a door lock 200, 1200, 2200, 3200.

In another exemplary setting of the security system 1, not shown, only the two door locks 200, 1200 are unlocked when one of the emergency buttons 10,1010 is actuated, and when one of the emergency buttons 2010, 3010 is actuated, only the other two door locks 2200, 3200 are unlocked. The emergency buttons 10, 1010 are therefore assigned to the door locks 200, 1200 and the emergency buttons 2010, 3010 to the door locks 2200, 3200. In particular, the safety system 1 adjusted in this way is suitable for two double-leaf doors, each with a door lock 200, 1200, 2200, 3200 per door leaf.

The security system 1 can also be set in such a way that when an emergency button 10, 1010, 2010, 3010 is actuated, all door locks 200, 1200, 2200, 3200 are unlocked.

Deviating from the security system 1, which is in figure 4 is shown, a security system 1 according to the invention can include a number of emergency buttons 10, 1010, 2010, 3010, which does not correspond to the number of door locks 200, 1200, 2200, 3200. E.g. can in figure 4 the door 2 can be single-leaf and one of the emergency buttons 10, 1010 or one of the door locks 200, 1200 is missing.

In figure 5 shows that the emergency buttons 10, 1010, 2010, 3010 and the door locks 200, 1200, 2200, 3200 are connected to one another via the first bus system 400. One emergency button 10, 1010, 2010, 3010 is electrically connected or can be connected to a key button 500, 1500, 2500, 3500 assigned to the respective emergency button 10, 1010, 2010, 3010 via a connection 402, 1402, 2402 or 3402. Alternatively, the key buttons 500, 1500, 2500, 3500 are connected to the first bus system 400 (not shown). In the embodiment of figures 4 and 5 if the control device 100 is in one of the emergency buttons 10, 1010, 2010, 3010, e.g. B. the emergency button 10 integrated. The first bus system 400 is only connected to a single control device 100 . Unless in the following described differently, the structure and the functions of the door locks 200, 1200, 2200, 3200 correspond to the structure and the functions of the door lock 200 of FIG figures 2 and 3 , the structure and the functions of the emergency button 10 the structure and the functions of the emergency button 10 of figure 2 and the structure and the functions of the emergency button 1010, 2010, 3010 the structure and the functions of the emergency button 10 of figure 3 . The reference numbers from figures 2 and 3 are used. It is understood that the door locks 200, 1200, 2200, 3200 each have their own door locking mechanism, their own processing means, etc., and the emergency buttons 10, 1010, 2010, 3010 each have their own emergency button processing units, alarm transmitters, lamps, switches and actuating elements.

So that the emergency buttons 10, 1010, 2010, 3010 can be assigned to the door locks 200, 1200, 2200, 3200, the emergency buttons 10, 1010 , 2010, 3010 to the door locks 200, 1200, 2200, 3200. For this purpose, one of the door locks 200, 1200, 2200, 3200 is switched to an assignment mode. Then a conscious action is taken at the emergency buttons 10, 1010, 2010, 3010. The deliberate action can be performed as an actuation of the actuating element 11 of the respective emergency button 10, 1010, 2010, 3010. After all emergency buttons 10, 1010, 2010, 3010 that are to be assigned to that door lock 200, 1200, 2200, 3200 that is in the assignment mode have been actuated, the assignment mode of the door lock 200, 1200, 2200, 3200 is ended. In the embodiment of figure 4 becomes e.g. B. first the door lock 200 transferred to the assignment mode and then the emergency button 10, 1010 is actuated, whereby the assignment of the emergency button 10, 1010 to the door lock 200 takes place. Then, the association mode of the door lock 200 is terminated. Then z. B. the door lock 1200 is transferred to the assignment mode and then the emergency button 10, 1010 is actuated, whereby the assignment of the emergency button 10, 1010 to the door lock 1200 takes place. Then the association mode of the door lock 1200 is terminated. The door lock 2200 is now transferred to the assignment mode and the emergency button 2010 is then actuated, as a result of which the emergency button 2010 is assigned to the door lock 2200. The door lock 2200 pairing mode is exited. The door lock 3200 and the emergency button 3010 can then be used accordingly.

The assignment stores in the respective door locks 200, 1200, 2200, 3200, in particular in the respective door lock controls 201, which emergency button 10, 1010, 2010, 3010 is to be assigned to the respective door lock 200, 1200, 2200, 3200. The assignment is in the control device 100 for all emergency buttons 10, 1010, 2010, 3010 and all door locks 200, 1200, 2200, 3200 of the first Bus system 400 the assignment of the emergency button 10, 1010, 2010, 3010 to the door locks 200, 1200, 2200, 3200 stored. A bus address, in particular an unchangeable bus address, of the respective emergency button 10, 1010, 2010, 3010 is stored for the assignment.

The assignment is stored in the respective door locks 200, 1200, 2200, 3200 in the first digital processing means 202 and redundantly in the second digital processing means 203, in particular in the non-volatile memories of the processing means 202, 203.

If e.g. B. the emergency button 10 is actuated, the emergency button 10 communicates with all door locks 200, 1200, 2200, 3200 of the first bus system 400. The door locks 200, 1200, 2200, 3200 each check on the basis of the deposit whether the respective door lock 200, 1200, 2200, 3200 has been assigned to the activated emergency button 10. The associated door locks 200, 1200 then only activate the respective door locking mechanism 205 if they are assigned.

In the event of a fire alarm signal, the door locks 200, 1200, 2200, 3200, which are assigned to the emergency button 10, 1010, 2010, 3010 receiving the fire alarm signal, are unlocked.

If a door lock 200, 1200, 2200, 3200 is to be unlocked with a time delay as a result of the actuation of an associated emergency button 10, 1010, 2010, 3010, a first delay time period is stored in that emergency button 10, 1010, 2010, 3010. The storage takes place when the safety system 1 is put into operation by the parameterization program. For each emergency button 10, 1010, 2010, 3010, a different first delay time can be stored by the operator. For example, a first delay time that differs from the first delay time that is stored in the emergency button 2010 is stored in the emergency button 10 . The emergency buttons 1010, 3010 are intended to unlock the associated door locks 2200 or 3200 without a time delay, so that the emergency buttons 1010, 3010 do not store a first delay time or a first delay time of 0 s. As an alternative to this, the safety system 1 can be designed in such a way that the emergency buttons 10, 1010, 2010, 3010, which are assigned to the same door lock 200, 1200, 2200, 3200, always have the same first delay time stored. For this purpose, the parameterization program allows the operator only one common setting.

The control device 100 takes over the non-safety-related functions for unlocking and locking all door locks 200, 1200, 2200, 3200, as before figure 1 and 2 described. For this purpose, the control device 100 with the Door locks 200, 1200, 2200, 3200 selectively communicate. It is stored in the control device 100 which door lock 200, 1200, 2200, 3200 is assigned to which access control system, so that in the event of a positive authentication signal from an access control system, only the assigned door lock(s) 200, 1200, 2200, 3200 are unlocked. Also stored in the control device 100 is whether and when, yes, which door lock 200, 1200, 2200, 3200 is to be unlocked at which predetermined time. It can also be stored in the control device 100 after which predetermined period of time or which predetermined periods of time which door lock 200, 1200, 2200, 3200 is to be locked again. Also stored in the control device 100 is whether and, if so, which door locks 200, 1200, 2200, 3200 are to be locked again immediately after the door 2, 2002, 3002 is closed. It can be stored in the control device 100 whether, and if so, for which door lock 200, 1200, 2200, 3200 an acoustic alarm should be triggered when the unlocked door 2, 2002, 3002 is opened without a positive authentication signal being present. It can be stored in the control device 100 whether an acoustic alarm should be triggered if the door 2, 2002, 2003 is not closed again. The deposits can be made differently for each door lock 200, 1200, 2200, 3200 or for the groups of door locks 200, 1200, 2200, 3200 to be arranged on a door 2, 2002, 3002. The storage is done with the help of the parameterization program by the operator during commissioning.

The control device 100 causes an acoustic and visual alarm as a result of the actuation of an emergency button 10, 1010, 2010, 3010 to also be output in the at least one other emergency button 10, 1010, 2010, 3010 of the same door lock 200, 1200, 2200, 3200 as the activated emergency button 10, 1010, 2010, 3010 is assigned. If in the embodiment of figures 4 and 5 e.g. If, for example, the emergency button 10 is actuated, the control device 100, by communicating with the electronic unit 24 of the emergency button 1010, causes the acoustic alarm device 23 and the lighting means 41 of the emergency button 1010 to also emit an acoustic or visual alarm.

If, after an emergency button 10, 1010, 2010, 3010 has been actuated, unlocking is initiated with a time delay, control device 100 causes the first delay period, with which unlocking is initiated, to also occur in the at least one further emergency button 10, 1010, 2010, 3010 is shown, which is associated with the same door lock 200, 1200, 2200, 3200 as the actuated emergency button 10, 1010, 2010, 3010. For this purpose, the control device 100 communicates with the electronics unit 24 of the at least one further emergency button 1010, 2010, 3010 or controls the lighting means 41 of the emergency button 10, in which the control device 100 is integrated.

The control device 100 can use the non-safety-related assignment for selective communication, e.g. B. assign an access control system to a door lock 200, 1200, 2200, 3200 based on a bus address. In this case, the participants of the first bus system 400 each have a setting device for manually setting a bus address. The setting device can include DIP switches. At least the users of the first bus system 400 that have the same setting on the setting device are automatically assigned to one another. In order to be able to assign different bus addresses to users with the same setting, users of the first bus system 400 have different identification numbers, from which different bus addresses are configured using the setting made. The bus address, which is determined with the help of the setting, is for the emergency buttons 10, 1010, 2010, 3010 and for the door locks 200, 1200, 2200, 3200, just another bus address that the emergency buttons 10, 1010, 2010, 3010 and use the door locks 200, 1200, 2200, 3200 in addition to the bus address used in a safety-related communication.

If a door lock 200, 1200, 2200, 3200 has already been unlocked, the control device 100 can prevent unlocking of a further door lock 200, 1200, 2200, 3200 until a condition is met, provided there is no danger. If the condition is met, the control device 100 causes the unlocking of the other door lock 200, 1200, 2200, 3200. In this way, the control device 100 communicates with a plurality of door locks 200, 1200, 2200, 3200 such that a lock is formed. For example, door 2002 may be located at an entrance to a room and door 3002 may be located at an exit of the same room. If a positive authentication signal for the door lock 2200 is present, the control device 100 can cause the door lock 2200 to be unlocked. Even if there is a positive authentication signal for the door lock 3200 of the control device 100, the control device 100 can prevent the unlocking of the door lock 3200 until a condition is present. If the condition is present, the control device 100 causes the door lock 3200 to be unlocked. B. a lock time interval or the achievement of a measured variable such as room temperature, humidity, air purity or number of people in the room. For this purpose, the control device 100 can be connected or can be connected to a measuring device. The condition may include the closing of the first opened door 2002, which is measurable by the door status monitors 204,206. The condition and the door locks 2200 , 3200 involved in the lock can be stored in the control device 100 . The storage can be done by the operator with the help of the parameterization program.

In figure 6 is a variant of the in den figures 4 and 5 shown security system 1 shown. Here, the control device 100 is designed separately from the emergency buttons 10, 1010, 2010, 3010 and the door locks 200, 1200, 2200, 3200. The first bus system 400 connects the control device 100 to the door locks 200, 1200, 2200, 3200 and the emergency buttons 10, 1010, 2010, 3010. The control device 100 of figure 6 corresponds to the structure of the control device 100 of FIG figure 3 . The emergency button 10 der figure 6 Corresponds in structure to the emergency button 10 of figure 3 . For the rest, the structure and the functionalities correspond to the previous ones figure 5 are described, the structure and the functionalities of the security system 1 of figure 6 .

The fact that in the embodiments of Figures 4 to 6 the door locks 200, 1200, 2200, 3200, the emergency buttons 10, 1010, 2010, 3010 and, if applicable, the control device 100 act as participants in a single first bus system 400, only the cables of the bus system 400 are necessary so that the participants can communicate with one another. The security system 1 thus has only a few cables.

The bus system 400 can include at least two cables for communication and at least two cables for power supply. In particular, the bus system 400 has exactly two cables for communication and two cables for the power supply. In each of the exemplary embodiments of the security system 1 according to the invention, a power pack can be integrated as a connection to a power grid at any point in the bus system 400 . Thus, the power pack can be provided as an independent component of the security system 1 outside of the emergency button 10 or the emergency buttons 10, 1010, 2010, 3010 and the door lock 200 or the door locks 200, 1200, 2200, 3200. As a result, the security system 1 is flexible in terms of spatial structure.

If, as in the third and fourth exemplary embodiment, there are several emergency buttons 10, 1010, 2010, 3010 and one of the emergency buttons 10, 1010, 2010, 3010 has been actuated, the electronic detection only prevents the emergency button 10, 1010, 2010, 3010 associated door locks 200, 1200, 2200, 3200 are locked. Reaching the cancellation condition enables the locking of the door lock(s) 200, 1200, 2200, 3200 assigned to the actuated emergency button 10, 1010, 2010, 3010. 1010, 2010, 3010, which was previously actuated, and authentication at the key switch 500, 1500, 2500, 3500 assigned to the actuated emergency button 10, 1010, 2010, 3010. At least this course of action is necessary for the door lock 200, 1200, 2200, 3200 assigned to the activated emergency button 10, 1010, 2010, 3010, in which at least one of the Door status monitoring devices 204, 206 has detected that the door 2 or one of the door leaves 3, 4 was opened after pressing the emergency button 10.

If the door status monitoring devices 204, 206 of the door locks 200, 1200, 2200, 3200 assigned to the activated emergency button 10, 1010, 2010, 3010 have detected that the door 2 has remained permanently closed after the emergency button 10, 1010, 2010, 3010 has been activated, the override condition may be met by the expiration of the predetermined time interval. For example, the cancellation condition can B. after 60 seconds after the last operation of the emergency button 10 can be reached. The permissibility of whether locking should take place after the predetermined time interval has elapsed with door 2, 2002, 3002 remaining closed can be for each door lock 200, 1200, 2200, 3200 or for groups of door locks 200, 1200, 2200, 3200, in particular for door locks , which are intended to be arranged on the same door, can be individually set and stored. The deposit can e.g. B. in the emergency buttons 10, 1010, 2010, 3010. Likewise, for each door lock 200, 1200, 2200, 3200 or for groups of door locks 200, 1200, 2200, 3200, in particular for door locks that are intended to be arranged on the same door, the length of the predetermined time interval can be stored in an individually adjustable manner. Here, a minimum length, z. B. 60 s, be fixed for the predetermined time interval. The storage is carried out by the parameterization program.

In figure 7 a fifth exemplary embodiment of the security system 1 according to the invention is shown. The fifth embodiment includes the security system 1 according to the first embodiment of FIG figures 1 and 2 . This means that the emergency button 10, which includes the control device 100, is connected to the door lock 200 via the bus system 400. The key switch 500 is connected or can be connected to the emergency button 10 via a connection 402 . In the fifth embodiment, additional components 300, 301, 510 are provided compared to the first embodiment.

The security system 1 comprises the central escape route control 300. The central escape route control 300 is intended to be arranged remotely from the door 2. So the central escape route control 300 z. B. together with a guard device 301, which can be designed as a monitor or personal computer, and/or a multi-door display device 350 (see 10 ) to be arranged in a guard room. The guard device 301 is optionally part of the security system 1 according to the invention. Alternatively, the guard device 301 can be connected to the security system 1 according to the invention.

The central escape route control 300 has a modular structure. An emergency module 310 includes a first mounting plate 311. The first mounting plate 311 takes a central Emergency button 302 and an identification device 312 embodied by way of example as a key button. The central emergency button 302 and the identification device 312 are mechanically rigidly connected to one another by means of the first fastening plate 311 . The central emergency button 302 serves to unlock the door lock 200 as a result of the central emergency button 302 being actuated. The door lock 200 can thus be unlocked remotely from the door 2 by the central emergency button 302 . The unlocking as a result of the actuation of the central emergency button 302 takes place with a one-fault security. The actuation of the central emergency button 302 is thus suitable for emergencies.

A deactivation module 320 comprises a first control element 322, embodied as a key switch, and a second control element 323, embodied as a button state transferred. If the emergency button 10 is in a deactivated state, an actuation of the emergency button 10 does not unlock the door lock 200. The second operating element 323 serves to activate the emergency button 10. If the emergency button 10 is in the deactivated state and becomes the second operating element 323 is actuated, the emergency button 10 is switched to an activated state. In the activated state of the emergency button 10, the emergency button 10 causes unlocking of the door lock 200 when the emergency button 10 has been actuated. The deactivation module includes a second mounting plate 321. The second mounting plate 321 serves to accommodate the first and the second control element 322, 323. The second mounting plate 321 mechanically rigidly connects the first and the second control element 322, 323 to one another.

A delay module 330 includes a third mounting plate 331. The third mounting plate 331 accommodates a delay element 332. FIG. The delay element 332 is embodied as a key switch, for example. The delay element 332 serves to further delay the unlocking of the door lock 200 within the first delay period. The delay module 330 includes a termination element 333, which is designed as a button. The terminating member 333 is fixed to the third fixing plate 331 . The termination element 333 is mechanically rigidly connected to the delay element 332 by means of the third fastening plate 331 . By actuating the terminating element 333, the delay in unlocking the door lock 200 can be terminated.

The central escape route control 300 comprises an escape route control housing 340 which is open on one side and in which the emergency module 310, the deactivation module 320 and the delay module 330 are arranged. The deactivation module 320 and the delay module 330 are optional components of the central escape route security system 300. In the escape route control housing 340, if present, the multi-door display device 350 can also be arranged.

The escape route control housing 340 can mechanically attach the emergency module 310 , the deactivation module 320 and the delay module 330 . The emergency module 310, the deactivation module 320 and the delay module 330 are each individually attached to the escape route control housing 340, in particular screwed. The first fastening plate 311 for the emergency module 310, the second fastening plate 321 for the deactivation module 320 and/or the third fastening plate 331 for the delay module 330 are used for fastening to the escape route control housing 340. The escape route control housing 340 and the modules 310, 320, 330 are designed in such a way that different sequences in which the modules 310, 320, 330 can be arranged next to one another are possible. So e.g. B. in a not shown central escape route security 300 z. B. the emergency module 310 between the deactivation module 320 and the delay module 330 can be arranged. In another exemplary central escape route control 300 that is not shown, a free space can be arranged on the left, the delay module 330 can be arranged in the middle, and the emergency module 310 can be arranged on the right. The space is created by the absence of the deactivation module 320 and is covered by a panel. The escape route control housing 340 can have rails for inserting the modules 310, 320, 330. The escape route control housing 340 can have mounting options, e.g. B. perforated strips or slots for variable attachment of the module 310, 320, 330 have.

On the first mounting plate 311, on the second mounting plate 321 and on the third mounting plate 331, a display area 314, 324 or 334, shown purely schematically, is provided in each case. Icons are present on the display area to explain the function of the modules 310, 320, 330. In addition, optical lights for displaying states of the security system 1 can be provided in the display areas 314, 324, 334.

In the embodiment of figure 7 the security system 1 further comprises an audio and video module 510. The audio and video module 510 is intended to be placed in the vicinity of the door 2, which can be locked by the door lock 200. With the audio and video module 510 enabled, an operator in the guard room can speak to the user in front of door 2 and view the room near door 2.

As in figure 8 shown, the central emergency button 302 is constructed similarly to the emergency button 10 . Thus, the central emergency button 302 includes an emergency button electronics unit 308. The emergency button electronics unit 308 includes a first emergency processing unit 303, a second emergency processing unit 304 and a third emergency processing unit 305. The first, second and third emergency processing units 303, 304, 305 are each designed as microprocessors or microcontrollers. The first and the second emergency processing unit 303, 304 have a non-volatile memory. The third emergency processing unit 305 has a non-volatile memory and/or has access to a non-volatile memory. The central emergency button 302 is activated by an emergency button activation element 306 being activated. As a result, an emergency button switch 307 is actuated. This generates a first and a second signal. For this purpose, a first and a second circuit (not shown) are opened. A first circuit opening signal is detected by the first emergency processing unit 303 . A second circuit opening signal is detected by the second emergency processing unit 304 .

The central emergency button 302 is connected to a second bus system 401 . As in figure 9 shown, the control device 100 is also connected to the second bus system 401 . The second bus system 401 is a different type of bus system than the first bus system 400. For example, the second bus system 401 can be in the form of a LON or LAN bus and the first bus system 400 can be in the form of a CAN or DCW bus.

In figure 9 includes the emergency button 10, the control device 100. The emergency button 10 and the door lock 200, in figure 9 are shown correspond to the emergency button 10 and the door lock 200 of figure 2 .

In an alternative, not shown, the control device 100, the emergency button 10 and the door lock 200 according to figure 3 educated. In this alternative, which is not shown, the control device 100, the emergency button 10 and the door lock 200 are connected to one another via the first bus system 400, with the control device 100 being connected to the second bus system 401.

The control device 100 receives messages from the central escape route security system 300 via the second bus system 401. The control device 100 forwards the messages to other participants in the first bus system 400 via the first bus system. In particular, the message can contain information regarding an actuation of the central emergency button 302, the key switch 312, the first control element 322, the second control element 323, the delay element 332 and/or the termination element 333 or a control command as a result of an actuation of one of the aforementioned elements 302 , 312, 322, 323, 332, 333. If the control device 100 is integrated in the emergency button 10, there is no forwarding to the emergency button 10 in which the control device 100 is integrated. For example, according to the figure 9 the control device 100 forwards the message to the door lock 200 . Are Control device 100 and the emergency button 10 are connected via the first bus system 400, the control device 100 forwards the message to the emergency button 10 and/or the door lock 200. The control device 100 adapts the message to the format of the first bus system 400 . Security-related messages are otherwise left untouched.

If the central emergency button 302 has been actuated, the first emergency processing unit 303 and, redundantly, the second emergency processing unit 304 cause the door lock 200 to be unlocked. 203. The first and the second processing means 202, 203 then control the locking mechanism 205. The first and second processing units 103, 104 have previously forwarded the message. Here, the control device 100 has left the content of the message untouched.

The central emergency button 302 has an input for receiving a fire alarm signal. If the fire alarm signal is received, the central emergency button 302 causes the door lock 200 to be unlocked. Like previously described.

A signal about an actuation of the key button 312 of the first module 310 is received by the emergency button electronic unit 308, in particular the third emergency processing unit 305. The emergency button electronics unit 308 sends a message regarding the actuation of the key button 312 via the second bus system 401 to the control device 100. The control device 100 forwards the message to the first bus system 400.

The emergency button actuating element 306 has a non-latching design. The emergency button actuating element 306 is designed identically to the actuating element 11 of the emergency button 10 (see Fig. Figures 13 to 15 ). In this way, the emergency actuating element 306 is transferred from an initial position to an actuating position when it is actuated (analogous to figure 11 ). Immediately after actuation, the emergency actuation element 306 moves back into the starting position by the force of a restoring means designed as a spring (analogous to figure 11 ). The actuation of the emergency actuation element 306 takes place in a translatory manner. If, as a result of the actuation of the central emergency button 302, the door lock 200 is switched to the unlocked state, the electronic device 207 prevents the electronic detection without the presence a cancellation condition, the door lock 200 can be transferred back into the locked state. The cancellation condition after the central emergency button 302 has been actuated can be achieved by actuating the key button 312 . In particular, an actuation of the key switch 312 is sufficient to achieve the override condition.

If the security system 1 includes the central escape route control 300, the cancellation condition can be reached in another way as a result of the emergency button 10 being actuated: if the door status monitoring devices 204, 206 have detected that the door 2 remained closed after the emergency button 10 had been actuated then the override condition may be achieved by elapse of a predetermined time interval and override treatment at the central escape route controller 300 after the predetermined time interval. The cancellation treatment can correspond to an authentication at the central escape route control 300, in particular an actuation of the key switch 312. Through the cancellation treatment, e.g. B. the actuation of the key switch 312, a cancellation signal can be generated. The cancellation signal is forwarded to the door lock controller 201 via the controller 100 . In this case, authentication at the key switch 500 and cancellation action at the emergency button 10 are not necessary.

The door locking controller 201 checks whether the cancellation condition can be reached by the predetermined time interval and authentication at the central escape route controller 300 with the door 2 remaining closed before the door locking controller 201 activates the locking mechanism 205 to lock. Thus, when starting up the security system 1, an operator can store whether the elapse of the predetermined time interval without opening the door 2 and the additional actuation of the key switch 312 is permissible as a cancellation condition and thus leads to the door 2 being locked again. Permissibility checking, elapse of the predetermined time interval, actuation of the key switch 312 after the predetermined time interval, and the fact that neither the first door status monitoring device 204 nor the second door status monitoring device 206 sent a door opening signal during the predetermined time interval , are sufficient to meet the override condition.

This is a variant of achieving an override condition that is part of the figures 1 and 2 was described. This variant can B. be selected by the operator if only the elapse of the predetermined time interval with the door 2 remaining closed does not seem safe enough to the operator. The operator can select and store this variant using the parameterization program.

In particular, if the operator has selected this option, the elapse of the predetermined time interval with the door 2 remaining closed is indicated optically on the central escape route control 300 . In particular, the lighting means 313 are used to indicate that the predetermined time interval has elapsed without a signal about the opening of the door 2 being received within the predetermined time interval. The operator learns from the optical display that the door 2 can be locked by the authentication at the central escape route control 300 .

If the door status monitoring devices 204, 206 have not sent a signal about opening the door while a fire alarm signal is present, the door lock 200 can also be locked by the same actuation of the key switch 312 after the fire alarm signal has ended. The possibility of locking the door lock 200 by actuating the key switch 312 after the fire alarm signal has ended is also indicated optically by the lighting means 313 .

The control device 100 forwards messages from the emergency button 10 and/or the door lock 200 via the second bus system 401 . In this case, the control device 100 adapts the message to the format of the second bus system 401 . Control device 100 sends information about the status of emergency button 10 and/or door lock 200 via second bus system 401.

For example, the central escape route control 300 and the multi-door display device 350 can be connected to a third bus system 403 (see Fig. 10 ). The central emergency button 302, particularly preferably the electronic emergency button unit 308, can preferably be connected to the third bus system 403 (see Fig. 8 ). The multi-door display device 350 can visually display the locked and unlocked status of the door lock 200 . In addition, one of the door locks 200, 200', 1200', 2200' of the security system 1 (see Fig. Fig.10 ) can be unlocked. Unlocking using the multi-door display device 350 is not single-fault-proof. The third bus system 403 can be the same type of bus system as the first bus system 400, e.g. B. a CAN or DCW bus.

The control device 100 forwards via the second bus system 401 to the central escape route control 300 if the emergency button 10 waits a first delay period before the emergency button 10 causes the door locking control 201 to activate the locking mechanism 205 for unlocking.

The first delay period is displayed visually at the central escape route controller 300 . For this purpose, the central emergency button 302 corresponds to the emergency button 10 constructed as it is to the figures 13 , 16, 17 is described. The lighting means 313 of the central emergency button 302 are controlled by the electronic emergency button unit 308 for the visual display of the first delay period. As the first delay period progresses, fewer illuminants 313 light up in the same color. For example, fewer illuminants 313 can illuminate in a first color and an increasing number of illuminants 313 can illuminate in a second color. The lamps 41 of the emergency button 10 are controlled in an identical manner in order to visually represent the first delay period.

During the first delay period, e.g. B. 8 s, the operator can actuate the delay element 332. To do this, the operator turns a key in the key switch, which serves as a delay element 332 . An actuation of the delay element 332 is detected by the emergency button electronics unit 308, in particular the third emergency processing unit 305. A corresponding message is sent via the second bus system 401 and possibly the first bus system 400. The emergency button 10 receives the message. As a result of the actuation of the delay element 332, the emergency button 10 ends the first delay period and begins a second delay period. The second delay period, e.g. B. 180 s, is longer than the first delay period. At the end of the second delay period, the emergency button 10 causes the unlocking of the door lock 200. The second delay period is determined in the emergency button 10 using the same timer that is used to determine the first delay period. During the second delay period, the key of the delay element 322 need not remain turned. Rather, turning the key once is sufficient to start the second delay period.

The second delay period is displayed visually on the central escape route control 300 and on the emergency button 10 . The visual display on the central escape route control 300 is the same as the visual display on the emergency button 10. As the second delay time progresses, fewer lamps 41, 313 light up in the same color. For example, fewer lamps 41, 313 can shine in a first color and an increasing number of lamps 41, 313 can shine in a second color. To represent that the second delay period is long, a timing-associating pattern, e.g. B. a rotating color dot or a rotating color window (see description of Figure 16, 17 ) can be displayed visually.

If the termination element 333 is actuated during the first or second delay period, the emergency electronics unit 308, in particular the third emergency processing unit 305, detects the actuation of the termination element 333 and transmits a message regarding the actuation of the terminating element 333 via the second bus system 401. As a result, the emergency electronics unit 308 causes the emergency button 10 to no longer delay the unlocking, but rather to immediately unlock the door lock 200. The terminating element 333 is non-latching. A single actuation of the termination element 333 is sufficient to terminate the delay in causing unlocking.

The emergency button 10 can be switched to the deactivated state by actuating the first operating element 322 . To do this, the operator turns a key in the key switch that serves as the first operating element 322 . An actuation of the first operating element 322 is detected by the electronic emergency button unit 308 . When the first operating element 322 is actuated, a first and a second deactivation circuit are opened or closed. Opening or closing of the first deactivation circuit is detected by the first emergency processing unit 303 . Opening or closing of the second deactivation circuit is detected by the second emergency processing unit 304 . The first and the second emergency processing unit 303, 304 communicate with the emergency button 10 via the second bus system 401. If the first bus system 400 is located between the emergency button 10 and the central emergency button 302, the control device 100 forwards the message from the first and the second emergency processing unit 303 , 304 further. When redirected, the format is changed, but the content remains unchanged.

In the deactivated state of the emergency button 10, actuation of the emergency button 10 has no effect on the door lock 200.

The activated state and the deactivated state are electronically stored in the emergency button 10 . Because the activated state and the deactivated state are stored in the emergency button 10, the key in the first operating element 322 does not have to remain turned during the deactivated state. Rather, turning the key once is sufficient to deactivate the emergency button 10 .

The deactivation remains until the second control element 323 is actuated. The actuation of the second control element 323 can be detected by the emergency button electronics unit 308, in particular the third emergency processing unit 305. The emergency electronics unit 308 sends a message regarding the actuation of the second operating element 323 via the second bus system 401 and possibly via the first bus system 400 to the emergency button 10, whereupon the emergency button 10 is transferred to the activated state. The second operating element 323 is non-latching. Because the activated and deactivated states are stored in the emergency button 10, a single actuation is sufficient of the second operating element 323 in order to convert the emergency button 10 into the activated state.

The central escape route control 300 includes a bus 341 via which the emergency electronics unit 308, in particular the third emergency processing unit 305, can detect signals from the second control element 323, the delay element 332 and the termination element 333. The emergency electronics unit 308 serves as intelligence for the entire central escape route control 300. Only the emergency electronics unit 308 includes microprocessors. The deactivation module 320 and/or the delay module 322 can be designed to be processor-free. The bus 341 can be designed as an I ² C bus.

A second variable can be stored in the first emergency button processing unit 20 and redundantly in the second emergency button processing unit 21, in particular in the non-volatile memories, to store the activated and the deactivated state. The second variable can be binary. If the emergency button 10 is in the deactivated state, the second variable is set to a deactivation value. If the emergency button 10 is in the activated state, the second variable is set to an activation value. As a result of an actuation of the first operating element 322, the second variable is set to the deactivation value. As a result of an actuation of the second operating element 323, the second variable is set to the activation value. Before the emergency button 10 causes the unlocking of the door lock 200, the emergency button 10 checks the value of the second variable. If the emergency button determines that the emergency button 10 is deactivated, then there is no communication between the emergency button 10 and the door lock controller 201 in order to initiate unlocking 200 .

The first emergency processing unit 303 and the second emergency processing unit 304 monitor each other for errors. If an error is detected, a message is sent via the second bus system 401. The emergency button 10 receives the message and then converts itself to the activated state if the emergency button 10 is in the deactivated state. For this purpose, the emergency button 10 changes the value of the second variable to the activation value.

The first emergency processing unit 303 and the second emergency processing unit 304 repeatedly send, in particular at regular intervals, a sign-of-life signal via the second bus system 401. The emergency button 10 receives the sign-of-life signals. If there is no sign-of-life signal once or several times, the emergency button 10 switches to the activated state if the emergency button 10 is in the deactivated state.

If the security system 1 receives a fire alarm signal, the emergency button 10 changes to the activated state if the emergency button 10 is in the deactivated state.

The actuation of the emergency button 10 in the deactivated state is displayed on the central escape route control 300, on the guard device 301 and/or on the multi-door display device 350. If there is actually a risk, the emergency button 10 can be switched to the activated state by the operator by actuating the second operating element 323, or the operator can directly control the door lock for unlocking. The operator can press the central emergency button 302 for this purpose. Whether there is a risk, the operator z. B. via the audio and video module 510 perceive. This achieves increased security.

The deactivation can e.g. B. be made at night in a department store. Furthermore, it is conceivable to use the deactivatable emergency button 10 in a building in which people with an impaired mental state live. Thus, emergency buttons 10 can also be used on doors to which people with impaired mental status have access, e.g. B. in a psychiatric or dementia ward.

If the emergency button 10 is actuated in the deactivated state and the emergency button 10 is then transferred to the activated state, the actuation of the emergency button 10 which took place in the deactivated state does not lead to an unlocking of the door lock 200 even after the transfer to the activated state deactivated state, pressing the emergency button 10 has no effect. On the one hand, this is due to the fact that the actuating element 11 and the switch 63 are non-latching. On the other hand, the actuation of the emergency button 10 in the deactivated state was not stored in the emergency button 10. The door lock controller 201 does not receive a message regarding the operation of the emergency button 10 in the deactivated state. The electronic determination was therefore not transferred to the actuation state. This ensures that the door lock 100 is not unlocked immediately when the emergency button 10 is activated, e.g. B. because the emergency button 10 was pressed long before. This achieves increased building security.

In order to achieve a particularly high level of security, it can be provided that the audio and video module 510 is switched on during the first and/or the second delay period. In this case, the emergency button 10 enables the audio and video module 510 at the beginning of the first and/or second delay period. The audio and video module 510 is also enabled by the emergency button 10 if the emergency button 10 is actuated in the deactivated state. For this purpose, the emergency button 10 communicates via the second Bus system 401 and possibly via the first bus system 400 with the audio and video module 510.

It may be that the emergency button 10 can only be deactivated if the audio and video module 510 can be unlocked. If the audio and video module 510 is part of the security system 1 according to the invention, deactivation can be omitted if the audio and video module 510 z. B. is not functional and / or the connection to the audio and video module 510 is faulty. This does not apply if the security system 1 does not include an audio and video module 510, but rather a monitoring system that is separate from the security system 1 is provided in the building.

It may be that the emergency button 10 only delays the initiation of the unlocking by the first and/or second delay period if the audio and video module 510 is unlockable. If the audio and video module 510 is part of the security system 1 according to the invention, a delay can be omitted if the audio and video module 510 z. B. is not functional and / or the connection to the audio and video module is faulty. This does not apply if the security system 1 does not include an audio and video module 510, but rather a monitoring system that is separate from the security system 1 is provided in the building.

In figure 10 a further exemplary embodiment of a security system 1 according to the invention is shown. As in the embodiment of Figures 7 to 9 includes the security system 1 a central escape route control 300, according to the figures 7 and 8th is constructed. Key buttons 500, 500', 1500, 1500', 2500 associated with the respective emergency buttons 10, 10', 1010, 1010', 2010 are not shown for the sake of clarity. The central escape route control 300 is connected to the second bus system 401 . A first subsystem 5 and a second subsystem 6 are connected to the second bus system 401 . The two subsystems 5, 6 each include a first bus system 400, 400'. Emergency buttons 10, 1010 or 10', 1010', 2010' and door locks 200 or 200', 1200', 2200' are connected to the respective first bus system 400, 400'. The first bus systems 400, 400' are the same type of bus system, e.g. B. a CAN or a DCW bus. The second bus system 401 is a different type of bus system, e.g. B. a LON or LAN bus.

The security system 1 comprises the multi-door display device 350. The multi-door display device 350 can e.g. B. visually indicate which door lock 200 or 200 ', 1200', 2200 'is in the unlocked state and which door lock is in the unlocked state. An operator can use the multi-door display device 350 to lock and unlock individual door locks 200 or 200′, 1200′, 2200′ of the security system 1 that are not safety-related.

Each subsystem 5, 6 comprises only one control device 100, 100'. In each case the control device 100, 100' of the respective subsystem 5, 6 is connected to the second bus system 401. The control device 100 of the first subsystem 5 is connected to the emergency buttons 10, 1010 and the door lock 200 of the first subsystem 5 via the first bus system 400. The control device 100' of the second subsystem 6, on the other hand, is integrated in an emergency button 10' of the second subsystem 6 and connected to the other emergency buttons 1010', 2010' and the door locks 200', 1200', 2200' of the further first bus system 400'.

A first emergency button 10 and a second emergency button 1010 are provided in the subsystem 5 . If one of the emergency buttons 10, 1010 is actuated, the actuated emergency button 10, 1010 causes the door lock 200 to be unlocked.

A first emergency button 10', a second emergency button 1010' and a third emergency button 2010' are provided in the subsystem 6. The emergency buttons 10', 1010', 2010' selectively cause the door locks 200', 1200', 2200' of the second subsystem 6 to be unlocked. For example, when the first emergency button 10' is actuated, only the first door lock 200' is unlocked. Accordingly, when the second emergency button 1010' is actuated, only the second door lock 1200' is unlocked, and when the third emergency button 2010' is actuated, only the third door lock 2200' is unlocked.

Various deviations are conceivable. Thus, a security system 1 according to the invention z. B. be configured without the first or the second subsystem 5, 6. As a single or additional subsystem z. B. one of the in the Figures 1 to 6 described security systems 1 according to the invention may be provided. The design and the functions of the emergency buttons 10, 10', 1010, 1010', 2010' and the door locks 200, 200', 1200', 2200' are designed in accordance with the previous exemplary embodiments, unless additionally or differently described below.

In each of the door locks 200, 200', 1200', 2200' of the security system 1 it is stored whether the respective door lock 200, 200', 1200', 2200' is unlocked when the central emergency button 302 is actuated. So e.g. B. allow the door locks 200, 200 ', 2200' an unlocking as a result of pressing the central emergency button 302, the door lock 1200 'not. If the central emergency button 302 is actuated, the door lock controls 201 of the door locks 200, 200', 2200' activate the respective locking mechanism 205 for unlocking. On the other hand, there is no such activation in the door lock 1200'.

If the central emergency button 302 is actuated, the control devices 100, 100' receive a corresponding message from the central emergency button 302 via the second bus system 401 and forward the message to all door locks 200 or 200', 1200', 2200' of the respective first bus system 400 , 400' further. The door locks 200, 200 ', 1200', 2200 'decide based on the deposit, which includes the approval of unlocking as a result of pressing the central emergency button 302, whether the respective door lock control 201 of the door locks 200, 200', 1200 ', 2200' the respective locking mechanism 205 controls for unlocking or not.

The storage of whether the door lock 200, 200′, 1200′, 2200′ is unlocked as a result of an actuation of the central emergency button 302 takes place when the security system 1 is put into operation by the operator. The storage is carried out by the parameterization program.

In each of the emergency buttons 10, 1010, 10'. 1010′, 2010′ is stored as to whether, when the first operating element 322 is actuated, the respective emergency button 10, 1010, 10′. 1010', 2010' is allowed or not. This results in selective deactivation by actuating the single first control element 322 of the security system 1. B. the emergency buttons 10, 10 ', 2010' are transferred to the deactivated state as a result of an actuation of the first operating element 322, the emergency buttons 1010, 1010 'but not.

If the first control element 322 is actuated, the control devices 100, 100' receive a corresponding message via the second bus system 401 and forward the message to all emergency buttons 10, 1010, 1010', 2010' of the respective first bus system 400, 400' that are not include the control device 100, further. The emergency buttons 10, 1010, 10'. 1010′, 2010′ of the security system 1 decide based on the deposit of permission for deactivation whether the respective emergency button 10, 1010, 10′, 1010′, 2010′ converts itself to the deactivated state as a result of the actuation of the first control element 322 or Not.

When storing whether a deactivation of the emergency buttons 10, 1010, 10', 1010', 2010' should be permitted, it can be a third variable. The third variable can be binary. The third variable is stored in the non-volatile memory of the respective first and second emergency button processing units 20, 21 of each emergency button 10, 1010, 10', 1010', 2010'. If deactivation is permitted for the respective emergency button 10, 1010, 10', 1010', 2010', then the third variable assumes a first value. If deactivation is prohibited for the respective emergency button 10, 1010, 10', 1010', 2010', the third variable assumes a second value. The emergency button 10, 1010, 10', 1010', 2010' checks the value of the third variable before the emergency button 10, 1010, 10', 1010', 2010' deactivates and deactivates only when the third variable has the first value.

The operator decides whether the emergency button 10, 1010, 10', 1010', 2010' can be deactivated when the safety system 1 is put into operation. This is stored using a parameterization program.

In each of the emergency buttons 10, 1010, 10'. 1010', 2010' it is stored whether, when the delay element 332 is actuated, the respective emergency button 10, 1010, 10'. 1010', 2010' the unlocking of the emergency button 10, 1010, 10'. 1010', 2010' associated door locks 200, 200', 1200', 2200' delayed by a second delay period or not. The second delay period is for the respective emergency buttons 10, 1010, 10'. 1010', 2010' of different lengths and stored in the security system 1, in particular in the emergency buttons 10, 1010, 10', 1010', 2010'. Alternatively, the delay by the second delay period and possibly the length of the second delay period can only be permitted for groups of emergency buttons 10, 1010, 10'. be individually adjustable. The setting and storage is carried out by the operator with the help of the parameterization program.

So e.g. For example, the emergency button 10, 2010' further delays the unlocking of the door locks 200 or 2200' as a result of an actuation of the delay element 332, whereas the emergency button 1010, 10', 1010' does not. The length of the second delay time for the emergency button 10 is selected to be different from the length of the second delay time for the emergency button 2010′. If the emergency button 10 is actuated and the delay element 332 is actuated within the first delay period stored for the emergency button 10, the emergency button 10 delays unlocking from the moment the delay element 332 is actuated by the second delay period stored in the emergency button 10 . If the emergency button 2010' is actuated and the delay element 332 is actuated within the first delay period that is stored for the emergency button 2010', the emergency button 2010' delays unlocking from the actuation of the delay element 332 by the second delay time that is stored in the emergency button 2010' is stored and which differs from the second delay time for the emergency button 10. If the emergency button 1010 is actuated, the emergency button 1010 delays unlocking by the first delay period that is stored for the emergency button 1010 . If the delay element 332 is actuated during the first delay period of the emergency button 1010, unlocking is not delayed by a second delay period since this delay is not permitted for the emergency button 1010, but the emergency button 1010 is activated after the first delay period immediately cause unlocking of the door lock 200. The emergency buttons 10', 1010' do not delay the unlocking of the associated door lock 200' or 1200' at all. Neither a first delay nor a second delay is permitted for the emergency buttons 10', 1010'. Instead of not allowing a delay by the first and/or the second delay period, a period of 0 s can also be stored. Actuation of the termination element 333 terminates any delay in unlocking.

If the delay element 332 is actuated, the control devices 100, 100' receive a corresponding message via the second bus system 401 and forward the message to the emergency buttons 10, 1010, 1010', 2010' of the respective first bus system 400, 400', which do not Control device 100 include further. The emergency buttons 10, 1010, 10'. 1010', 2010' of the security system 1 use the deposit to decide how to proceed.

The deposit as to whether the emergency button 10, 1010, 10', 1010', 2010' allows the delay by the second delay period and, if so, the deposit of the length of the second delay period, takes place when the safety system 1 is put into operation. The deposits are made by the Operator defined with the help of the parameterization program. The first and/or the second delay time period can only be selected up to a maximum, fixed predetermined time period.

The operator can also use the parameterization program to selectively store which cancellation condition is permitted for which emergency button 10, 1010, 1010', 2010'. The cancellation condition for the cancellation action on site is always permitted. For each emergency button 10, 1010, 1010′, 2010′, however, it is possible to selectively allow the cancellation condition to be reached by the predetermined time interval elapsing or the cancellation condition to be reached by the predetermined time interval elapsing and the identification device 312 then being actuated with the door 2 remaining closed or not.

The storage of whether the emergency button 10 can be deactivated when the first operating element 322 is actuated, whether the emergency button 10 should delay unlocking by a second delay period when the delay element 332 is actuated, the length of the first and second delay periods, the storage of the cancellation condition and /or the deposit of whether the door lock 200 is to be unlocked when the central emergency button 302 is actuated can also be used for the security system 1 according to the exemplary embodiment of FIG Figures 7 to 9 be made.

Deviating and not shown from the Figures 7 to 10 several central escape route controls 300, 300' can also be connected to the second bus system 401. For example, in a psychiatric ward, a central escape route control 300 can be provided for arrangement in a guard room and a further central escape route control 300′ can be provided for arrangement in a nurses’ room.

In the respective door locks 200, 200', 1200', 2200' it can be stored with the aid of the parameterization program which of the central emergency buttons 302, 302' should be unlocked as a result of an actuation. A list is stored in the door locks for this purpose. In the respective emergency buttons 10, 10′, 1010, 1010′, 2010′ it can be stored with the aid of the parameterization program which of the first operating elements 322, 322′ is permitted to be deactivated as a result of an actuation. Deviating from the third variable, a list is stored in each of the emergency buttons 10, 10', 1010, 1010', 2010'.

The first to fourth exemplary embodiments of the security system 1 according to the invention have no second bus system 401 , no central escape route control 300 , no guard device 301 and no audio and video module 510 . However, exemplary embodiments of the security system 1 according to the invention are conceivable in which the first to fourth exemplary embodiments additionally include the missing components 401, 301, 300 and 510 at least in part. If the security system 1 is designed for several doors, an audio and video module 510 can be assigned to each door. The emergency buttons 1010, 2010, 3010, which do not include the control device 100, and the door locks 200, 1200, 2200, 3200 are not connected to the second bus system 401.

In the Figures 1 to 10 the door locks 200, 200', 1200, 1200', 2200, 2200', 3200 are part of the security system 1 according to the invention. However, it is conceivable that only the door lock controls 201 are part of the security system 1 according to the invention. In this case, the door locking controls 201 can be connected to the locking mechanism 205 and, if necessary, to the door status monitoring devices 204, 206, respectively. In this case, the door lock 200 is not unlocked in the security system 1, but part of the security system 1 is that the door lock control 201 controls the locking mechanism 205, ie the door lock control 201 switches the electrical current for the locking mechanism 205 on or off. In this case, instead of the terms "unlocking or locking of the door lock" respectively "actuation of the locking mechanism for unlocking or locking" can be used.

In the Figures 11 to 13 an emergency button 10 is shown. the inside figure 11 The emergency button 10 shown is an emergency button 10, 10', 1010, 1010', 2010, 3010 in one of the security systems 1 according to the invention Figures 1 to 10 usable or used.

The emergency button 10 includes the actuating element 11. The actuating element 11 can be moved from the initial position 11.I, which is in the figure 11 is shown, move to the operating position 11.II, which is shown in figure 11 is indicated. In figure 12 the actuating element 11 is also in the starting position 11.I.

In the operating position 11.II, the switch 63 is operated. The switch 63 also changes from a first position 63.I to a second position 63.II, as in figure 12 implied.

After actuation, the actuating element 11 returns to the starting position 11.I immediately and without manual intervention. For this purpose, a restoring means 12 designed as a spring is provided in the emergency button 10 . The switch 63 also returns to the first position 63.I immediately and without manual intervention after it has been actuated.

The emergency button 10 comprises at least a first circuit board 60. This makes it possible to design the emergency button 10 in a compact manner and with reliable functionality.

The emergency button 10 has a height AH of less than 48 mm, preferably less than 45 mm, particularly preferably less than 43 mm from a crest 32 of a front surface 19 of the actuating element 11 in the installation direction.

The switch 63 is fixed on the first circuit board 60 . The first and the second circuit are interrupted on the first circuit board 60 by actuating the switch 63 .

The emergency button 10 also includes a second circuit board 61. The first, the second and the third emergency button processing unit 20, 21, 22 are arranged on the second circuit board 61. The arrangement of the first, second and third emergency button processing units 20, 21, 22 is independent of whether the first, second and third emergency button processing units 20, 21, 22 serve as processing units 103, 104, 105 of the control device 100.

The first and second emergency button processing units 20, 21 can detect the opening of the first and second circuits without cables. For this purpose, the first and the second circuit board 60, 61 are connected to one another via plugs 68.

The first and second sinkers 60, 61 are arranged at a fixed distance from each other. Bolts 69 are provided for this purpose, which fasten the first and second circuit boards 60, 61 to one another at a fixed distance from one another via screws 70 (see Fig. figure 13 ). The first and second sinkers 60, 61 are arranged parallel to each other.

The emergency button 10 includes a mounting plate 62. The mounting plate 62 is also arranged at a fixed distance from the first and the second circuit board 60, 61. Bolts 71 are provided for this purpose, which connect the mounting plate 62 to the first circuit board 61 via screws 72 .

The mounting plate 62 is used for attachment to a flush-mounted box. The flush-mounted box can have a diameter of 60 mm and a depth of 41 mm. The part of the emergency button 10 that extends from the mounting plate 62 in the direction of installation is referred to as the built-in part 73 . The built-in part 73 has a diameter of less than 60 mm and a depth of less than 33 mm, preferably less than 31 mm, particularly preferably less than 29 mm. This leaves enough space for cables in the flush-mounted box. The distance MP from an underside of the mounting plate 62 to an upper side of the second circuit board 62 is less than 22 mm, preferably less than 20 mm, particularly preferably less than 17 mm. The mounting plate 62 can also be used for attachment to a cover element of a surface-mounted housing (not shown). The distances mentioned apply in particular to an emergency button in which the Bluetooth module 64 is attached to an underside of the second circuit board 61, in contrast to the illustration in the figures.

As described above, the override action performed directly on the emergency button 10 is performed without rotating the actuator 11 and the switch 63. This makes it possible to use a switch 63 with a small height. Thus, the switch 63 is formed such that the switch 63 is free from rotation. The switch 63 has a height SH of less than 20 mm, preferably less than 17 mm, particularly preferably less than 15 mm.

The type of cancellation action and the low height of the switch 63 contributes to the low overall height AH of the emergency button 10.

The fact that the switch 63 is arranged centrally under the actuating element 11 and the actuating element 11 is guided eccentrically in the emergency button 10 also contributes to the low installation height AH of the emergency button 10 .

As in the Figures 14 and 15 shown, the actuating element 11 has rod-shaped guide means 35 . The guide means 35 are guided in guide sleeves 65 . The guide sleeves 65 are connected to the mounting plate 62 . In order to achieve good guidance, one of the guide sleeves 65 extends through the first plate 60.

The guide means 35 are arranged parallel to the switch 63 . The guide means 35 prevent a rotational movement of the actuating element 11 about an imaginary axis 701 which runs in the direction of actuation 700 .

The actuating element 11 can only be moved in a translatory manner by the guide means 35 guided in the guide sleeves 65 .

The actuating element 11 has an actuating means 36 . As in the figures 12 and 15 shown, the actuating means 36 is in the form of a circular cylinder. This ensures that the actuating means 36 always actuates the switch 63 . In particular, a first and a second switching element 74, 75 of the switch are always actuated simultaneously (see Fig. figure 13 ). The first circuit is opened by the first switching element 74 and the second circuit is opened by the second switching element 75 .

The actuator 36 is formed with a hollow interior 38 . In the switch 63, a light source (not shown) is arranged. The light emitted by the light source is directed through the hollow interior 38 to the crest 32 of the front face 19 of the actuator 11 where the light passes through the actuator 11 . The tip 32 thus serves as an illuminating area 32 of the actuating element 11.

The actuating element 11 can comprise an opaque base body 33 . The base body 33 can be provided with an opening in deviation from the representation in the figures. A light-permeable, in particular translucent, insert (not shown) can be arranged in the opening. The insert can be fastened in the opening, in particular pressed in. As a result, the actuating element 11 can be produced in a particularly simple manner.

The front surface 19 is partially conical. The illuminating area 32 forms the tip of the truncated cone. The illuminated area 32 protrudes from a cover 14 of the emergency button 10 against the direction of actuation 700 . As a result, the light that leaves the illuminated area 32 is clearly visible to the side of the emergency button 10 .

The restoring means 12 has a cavity 37 . The actuating means 36 of the actuating element 11 and the switch 36 with the first and the second switching element 74, 75 protrude into the cavity 37. This results in a space-saving arrangement.

The Bluetooth module 64 is arranged between the first and the second circuit board 60, 61. The Bluetooth module 64 is used for parameterization. Alternatively and not shown, and more space-saving, the Bluetooth module 64 is attached to a side of the second circuit board 61 facing away from the actuating element 11 . As a result, the distance between the first and the second circuit board 60, 61 can be further reduced.

A tamper switch 66 is arranged on the first circuit board 60 . Because of the low overall height, an actuating extension 67 of the sabotage switch 66 is passed through the mounting plate 62 . The actuating extension 67 rests directly on the cover 14 of the emergency button 10 .

If the control device 100 is integrated in the emergency button 10, the emergency button 10 can include the functions described above, despite the low installation height AH, and can therefore be configured intelligently. The functions described above are executed using a program code that is stored in at least one of the processing units 103, 104, 105.

The emergency button 10 has a cover 13 . The covering means 13 is transparent and covers the front surface 19 of the actuating element 11 . As a result, the covering means 13 prevents the user from directly touching the actuating element 11 . The covering means 13 serves as a mental obstacle for the user.

The cover 13 remains non-destructive when the emergency button 10 is actuated. When the emergency button 10 is actuated, the covering means 13 moves from a starting position 13.I into an actuating position 13.II. The covering means 13 actuates the actuating element 11 only indirectly via the covering means 13 by the user.

The covering means 13 is arranged in the emergency button 10 so that it cannot be removed. The result of this is that a user cannot improperly remove the covering means 13 .

The covering means 13 is firmly connected to the actuating element 11 . For this purpose, the covering means 13 has extensions 27, which figure 13 are shown. As in the figures 13 , 14 and 15 shown, the actuating element 11 has holes 28 through which the extensions 27 are guided and connected to the actuating element 11 in a materially bonded manner.

The actuating element 11 has a flange-like section 31 to which the covering means 13 is fastened. The flange-like section 31 has the holes 28 .

The flange-like section 31 serves as a stop for the actuating element 11 in the direction of actuation 700. The actuating element 11 reaches the actuating position 11.11 when the flange-like section 31 rests against the mounting plate 62 or against the guide sleeves 65.

The flange-like section 31 serves as a stop for the actuating element 11 against the direction of actuation 700. The actuating element 11 reaches the initial position 11.I when the flange-like section 31 rests against a light guide 40. The light guide 40 holds the actuating element 11 against the force of the restoring means 12. The light guide 40 has a contact surface 51 for this purpose.

The light guide 40 is attached to the mounting plate 62 . As a result, the actuating element 11 is held against the force of the restoring means 12 even when the cover 14 is removed. The light guide 40 has a flange 52 with which the light guide 40 is attached to the mounting plate 62 (see Fig. 17 ). The light guide 40 is through the same screws 72 are attached to the mounting plate 62 by which the mounting plate 62 is attached to the first circuit board 60 .

Alternatively and not shown, the covering means 13 can be designed as an elastic foil that spans the actuating element 11 .

Due to the fixed connection, the distance between the operating position 11.II and the initial position 11.I and the distance between the operating position 13.II and the initial position 13.I correspond to one another. Immediately after the end of the actuation and without manual action, the covering means 13 is moved back into the starting position 13.I. The restoring means 12 is used for this purpose. The restoring means 12 transfers the covering means 13 indirectly via the actuating element 11 into the starting position 13.I.

The covering means 13 and the actuating element 11 each have a circular cross section. The cover 14 has a circular recess 15 . The covering means 13 protrudes through the recess 15 counter to the direction of actuation 700. The actuation element 11 also protrudes through the recess 15.

The recess 15, the actuating element 11 and the covering means 13 have a common imaginary axis 701. The recess 15, the actuating element 11 and the covering means 13 are arranged concentrically.

The covering means 13 has an actuating surface 17 which is at a distance from the front surface 19 of the actuating element 11 . The covering means 13 also has a side surface 16 which is formed at a distance from the side surface 18 of the actuating element 11 .

Due to the spacing of the front surface 19 and the actuating surface 17, the transparent covering means 13 can project far out of the cover 14, while the partially opaque actuating element 11 projects out of the cover 14 only to a small extent. As a result, the light guide 40, which is essentially flush with the cover 14, remains clearly visible even to users standing at an angle in front of the emergency button 10. The light guide deviates at most ±3 mm, preferably at most ±2 mm, particularly preferably ±1 mm from a planar termination with the cover 14 .

Due to the fact that the covering means 13 protrudes far out of the cover 14, the user can operate the emergency button 10 with the palm of his hand. For this purpose, the covering means 13 is flush with the cover 14 in the operating position 13.II or the covering means 13 protrudes from the cover 14 against the operating direction 700 in the operating position 13.II. In other words, the distance ABS of the starting position 13.I and the operating position 13.II corresponds at most to the distance DF of an elevation 30 of the operating surface 17 to the cover 14. The amount of the distance AB also corresponds to the

Actuating position 11.II and the starting position 11.I at most the distance DF. In figure 11 the distance ABS and the magnitude of the distance AB correspond to the distance DF.

The emergency button 10 includes lamps 41. The lamps 41 are used to display the unlocked and locked state of the door lock 200. If there are several emergency buttons 10, 1010, 2010, 3010, the lamps 41 indicate the unlocked and locked state of the associated door lock or door locks 200, 1200, 2200, 3200. The lighting means 41 are arranged concentrically around the actuating element 11 . For example, the unlocked state is indicated by a green light and the locked state is indicated by a red light. In particular, all light sources 41 emit the same light to indicate the locked and unlocked state, at least if there is no danger.

The lighting means 41 can be controlled in at least two groups. Due to the different control z. B. patterns are possible through which the user more states of the security system 1 are displayed. As a result of the additional display options, a large number of states can be displayed to the user and/or the operator in a compact and simple manner without additional display means. This increases the security of the security system 1 .

In figure 13 1 shows six individual illuminants of the eight individual illuminants 41 present by way of example, of which three illuminants are provided with the reference symbols 41a, 41b, 41c. The individual light sources are referred to below as 41a, 41b, 41c, etc.

Each of the individually controllable groups of light sources 41 can only include a single light source 41a, 41b, 41c, etc. In the embodiment of Figures 11 to 17 each lamp 41a, 41b, 41c, etc. can be controlled individually. Each light source 41a, 41b, 41c, etc. is in the form of an RGB LED. The lamps 41a, 41b, 41c, etc. can be controlled in such a way that each lamp 41a, 41b, 41c, etc. can emit at least four different, preferably at least five different, colors. This can be z. B. be red, blue, yellow, green and pink light.

The lighting means 41 are controlled by the third emergency button processing unit 22 . For this purpose, the emergency button processing unit 22 and the lighting means 41 are connected to a ring bus (not shown).

The lighting means 41 are arranged on the first circuit board 60 . The acoustic alarm device 23 is also arranged on the first circuit board 60 . The acoustic alarm device 23 is activated by the third emergency button processing unit 22 .

Are several door locks 200, 1200 associated with the emergency button 10 such. Am figure 4 shown, at least two options are conceivable. On the one hand, the emergency button 10 can only display the unlocked state when all the door locks 200, 1200 assigned to the emergency button 10 are in the unlocked state. Here, the unlocked state is only displayed when the entire escape door width of the two door leaves 3, 4 is available for escape. Alternatively, the emergency button 10 already indicates the unlocked state when one of the door locks 200, 1200 or all the door locks of a door leaf 3, 4 are in the unlocked state. As a result, the possibility of escape is displayed as early as possible when one of the door leaves 3, 4 is unlocked. The options can be selected by the operator. For this purpose z. B. a switch (not shown) in the security system 1 may be provided.

A further state of the security system 1, which is indicated by the lighting means 41 that can be controlled in groups, is danger. In this case, the lighting means 41 can indicate whether a fire alarm signal is present or whether an actuation signal has been generated.

The lighting means 41 can be controlled in such a way that the progression of the time delay of the unlocking after the activation signal has been generated by the lighting means 41 is displayed. Here emit z. B. increasingly fewer lamps 41 light of one color, in particular red light.

As a further state of the security system 1, which can be represented by the lighting means 41, a fault can be represented by the lighting means 41. The error that can be represented in this way can be an error in the safety system 1 . For example, it can be indicated that the control device 100, the door locking control 200 or the first or the second emergency button processing unit 20, 21 of the security system 1 is not operational, defective, failed, switched off intentionally or has been removed. The fault can be a fault of the alarm system connected to the security system 1, which is inoperable, defective, failed, intentionally switched off or removed.

The light guide 40 comprises a plurality of light guide regions 44 (see Figures Figures 16 and 17 ). Each of the lighting means 41a, 41b, 41c, etc. is assigned a light guide area 44 in each case. The light guide 40 can be mentally divided into the light guide areas 44 . Recesses 46 are provided between the light guide regions 44 . Due to the recesses 46, the light essentially remains in the light guide areas 44.

Each light guide area 44 has a forwarding section 48 . The forwarding section 48 is arranged above the lighting means 41 in the transmission direction 702 . The direction of transmission 702 is opposite to the direction of actuation 700. The forwarding section 48 is used to guide light up to a spreading Section 45 of the light guide area 44. The spreading section 45 spreads out in the transmission direction 702.

The spreading section 45 follows the forwarding section 48 in the transmission direction 702 . The spreading section 45 serves to widen the light beam of the emitted light. The forwarding section 48 widens less than the expanding section 45.

The light guide 40 is formed in one piece. The light guide 40 is made of the same material, in particular monolithic. The light guide 40 is made of translucent material.

The light guide areas 44 have a connecting section 49 . The connecting section 49 adjoins the expanding section 45 in the transmission direction 702 . The connecting sections 49 of the light guide regions 44 are connected to one another in one piece in such a way that the one-piece light guide 40 that is made of the same material results.

The connecting sections can have a depth of 2 mm to 6 mm, preferably 3 mm to 5 mm, particularly preferably 3.5 mm to 4.5 mm. As a result, the light from one of the lamps 41a, 41b, 41c, etc. is almost limited to a lighting area 50a, 50b, 50c, 50d, 50e, 50f, 50g, 50h on the surface 47 of the light guide 40 facing the user. Each light guide area 44 includes a lighting area 50a, 50b, 50c, 50d, 50e, 50f, 50g, 50h.

The surface 47 of the light guide 40 corresponds to a circular ring. The luminous areas 50a, 50b, 50c, 50d, 50e, 50f, 50g, 50h are designed as sectors of the circular ring. The associated luminous area 50a, 50b, 50c, 50d, 50e, 50f, 50g, 50h is illuminated by the emission of light from a luminous means 41a, 41b, 41c, etc. The circular ring encloses the actuating element 11.

The lamps 41 can be controlled in such a way that at least one lamp 41a, 41b, 41c, etc. emits the light of one color and at least one other lamp 41a, 41b, 41c, etc. emits the light of a different color at the same time. In this way, for example, the luminous areas 50a, 50b, 50e, 50f can display light of one color and the luminous areas 50c, 50d, 50g and 50h can display light of another color. While the luminous areas 50a, 50b, 50e, 50f z. B. are continuously illuminated, the luminous areas 50c, 50d, 50g and 50h may be illuminated by illuminants 41 that emit blinking light.

are e.g. B. First, the luminous areas 50a, 50b, 50e, 50f are illuminated by light of a first color and the luminous areas 50c, 50d, 50g and 50h by light of a second color; then the luminous areas 50a, 50h, 50d, 50e are illuminated by the light of the first color and the luminescent areas 50b, 50c, 50f and 50g of light of the second color; If the luminous areas 50h, 50g, 50d, 50c are then illuminated by light of the first color and the luminous areas 50a, 50b, 50e and 50f by light of the second color, the impression of a circumferential color window is created.

The opposing luminous areas 50, ie the luminous areas 50 which lie on a straight line leading through the imaginary axis 701, in figure 14 namely 50a and 50e or 50b and 50f or 50c and 50g or 50d and 50h are preferably illuminated in the same way, ie in the same color and the same flashing frequency. Thus, the pattern can also be guessed at for users standing at an angle in front of the emergency button 10, even if at least one of the opposing luminous areas 50 is covered by the actuating element 11.

So that the light guide 40 is covered as little as possible, the illuminating area 32 protrudes at most 10 mm, preferably at most 7 mm, particularly preferably at most 5 mm above the light guide 40 .

The emergency button 10 can include a brightness sensor (not shown). The brightness sensor measures the ambient brightness of the emergency button 10. If the ambient brightness decreases, the luminous intensity of the light emitted by the lamps 41 is also reduced.

Via the Bluetooth module 64, parameters can be set via a mobile communication device, e.g. B. in which way the lamps are to be controlled in which state of the security system 1. The parameters include the flashing frequencies of the lamps 41, whether a continuous or a flashing light is to be emitted, which state is to be indicated by which color. After the parameterization, the settings are stored in an electronic memory of the security system 1, in particular of the control device 100. Likewise, for safety reasons, the display of certain states cannot be selectable for the operator and can be permanently stored in the electronic memory. The operator can himself select states of the security system 1 which the operator would like to display through the lighting means 41 . For this purpose, colors and/or patterns can be emitted by the lighting means 41 that are not assigned to any predetermined state. For example, the operator can choose which condition the operator would like to be indicated by blue light. In addition to parameterization via the Bluetooth module 64, parameterization via the monitoring device 301 is possible.

The change in the status of the door lock 200 is then displayed after the door lock controller 201 has sent the status change to the control device 100 has communicated. The control device 100 then controls the lighting means 41 or causes the lighting means 41 to be controlled.

When the security system 1 is put into operation, several initialization views are successively generated by the lighting means 41 at fixed time intervals. Possible activated functions of the control device 100 are displayed in one of the initialization views. In a second initialization view, the emergency buttons 10, 1010, 2010, 3010 and door locks 200, 1200, 2200, 3200 that can be integrated into the security system 1 are displayed, with the status error-free/faulty/not present being displayed. The status of inputs and outputs is displayed in a third initialization view.

The central emergency button 302 is constructed almost identically to the emergency button 10 . In particular, the operating element 11 corresponds in function and structure to the emergency button operating element 306. The switch 63 corresponds to the emergency button switch 307. The central emergency button 302 also includes a resetting means corresponding to the resetting means 12. The central emergency button 302 comprises a first and a second circuit board and/or a mounting plate, which are constructed and connected to one another in accordance with the first circuit board 60, the second circuit board 61 or the mounting plate 62. The alarm transmitter 309 and the lighting means 313 are arranged on the first circuit board of the central emergency button 302 in accordance with the alarm transmitter 23 and the lighting means 41 . The first to third emergency processing units 303, 304, 305 are arranged on the second printed circuit board of the central emergency button 302. The emergency button switch 307 ends on the first circuit board of the central emergency button 302. When the emergency button switch 307 is actuated, a first and a second circuit are opened on the first circuit board, which can be detected wirelessly by the first and the second emergency processing unit 303, 304. For this purpose, the first and the second circuit board are connected via plugs. The light guide of the central emergency button 302 corresponds to the light guide 40 in structure and function.

It is conceivable that in the case of the central emergency button 302 a covering means 13 corresponding to the covering means 13 is configured differently or is missing. The lamps 313 are not used in particular to visually indicate a locked state of an emergency button 10. The lamps 313 are used to indicate the first and the second delay period and/or to indicate that cancellation is possible.

The security system 1 according to the invention does not necessarily have to have all the functions that are specified in the description for at least one of the Figures 1 to 10 is mentioned, can perform. Rather, although in the security system 1, the functions that are in the description at least one of the Figures 1 to 10 are mentioned, deposited. However, in order to be able to execute the functions, the functions must be activated. This takes place in that the control device 100 communicates with a communication module 801 . The communication module 801 is designed as a chip card. The communication module 801 includes a memory in which at least one code for activating at least one function is stored. The communications module 801 includes a microprocessor that is only used to encrypt the code. The communication module 801 is pushed into a receptacle 77 of the control device 100 (see Fig. 18a ). The arrangement in the receptacle 77 mechanically holds the communication module 801 in the receptacle 77 in a positive and/or non-positive manner. At the same time, the arrangement in the receptacle 77 makes electrical contact with the communication module 801, so that the control device 100 can read out the at least one code from the communication module 801. In this case, the control device 100 and the communication module 801 are wired (not shown).

In order to read out the code, the control device 100 must first be given access to the communication module 801 with the aid of a password. The control device 100 must decrypt the at least one code before the function can be activated. By enabling the function, the program code that can be used to execute the function is enabled.

To enable the function, the program code that can be used to execute the function is enabled. If the program code is stored on the emergency button 10 and the control device 100 and the emergency button 10 are connected to one another by the first bus system 400, then after the code of the communication module 801 has been read out, the control device 100 initiates activation in the emergency button 10 via the first bus system 400. Is If the program code is stored in the door locking controller 201, then after the code of the communication module 801 has been read out, the control device 100 initiates activation in the door locking controller 201 via the first bus system 801.

A code can unlock one or more functions, especially function blocks.

In the parameterization program, only parameters for the functions that have been released before can be set. Only these parameters are displayed on the screen.

The function only remains activated if the code is repeatedly read out of the communication module 801 again, in particular at regular time intervals.

For this purpose, predefined, non-adjustable time intervals can be stored in the control device 100 . After the specified time interval has elapsed, the control device 100 blocks the function if the associated code could not be read from the communication module 801 . If the function is performed by the emergency button 10, which is connected to the control device 100 via the first bus system 400, then the control device 100 causes the function to be blocked via the first bus system 400. If the function is performed by the door lock controller 201, which is connected to the control device 100 via the first bus system 400, then the control device 100 causes the function to be blocked via the first bus system 400.

Several codes Code1, Code2 for different functions can be stored on the 801 communication module (see Fig. 18a ).

If an additional function is to be released, it is conceivable to remove the communication module 801 from the mount 77 and to insert another communication module 802 into the mount 77 (see Fig. Figure 18b ). The communication module 801 is referred to as the mother module 801 in the following. The additional communication module 802 is referred to below as an auxiliary module. The auxiliary module 802 is designed as a chip card. The auxiliary module 802 includes a memory in which at least one code for enabling the additional function is stored. The auxiliary module 802 includes a microprocessor that is only used to encrypt the code.

The code Code3, which is stored on the auxiliary module 802, is read out by the control device 100 (see Fig. Figure 18b ). In order to read out the code Code3, the control device 100 must first have access to the auxiliary module 802 with the aid of a password. The control device 100 must decrypt the at least one code before the function can be activated. The code Code3 of the auxiliary module 802 is stored in a memory 107 of the control device 100 (see Fig. 18c ). After that, the code of the auxiliary module 802 on the auxiliary module 802 is deleted (see 18c ). The auxiliary module 802 is removed from the receptacle 77 . Then the mother module 801 is pushed into the receptacle 77 (see Fig. Figure 18d ). The code of the auxiliary module 802 is stored on the mother module 801 (s. Figure 18d ). The code is deleted from the memory of the control device 100 (see Figure 18d ). The additional function will be unlocked.

In the case of a mother module 801, on the other hand, the code is not stored in the control device 100 (see Fig. Fig. 18a, d ). With a mother module 801 the code is not deleted. Rather, the mother module 801 is used for a permanent arrangement in the receptacle 77. The codes Code1, Code2, Code3 stored on the mother module 801 become read repeatedly. The control device 100 uses an identifier K801, K802 of the communication module 801, 802 to decide whether it is a mother module 801 or an auxiliary module 802. The identifier K801, K802 is stored electronically in particular on the mother module 801 and the auxiliary module 802. The identifier K801 of the mother module 801 differs from the identifier K802 of the auxiliary module 802.

The insertion and removal from the receptacle 77 is done manually. The rest of the operations are automatic.

The insertion and removal from the receptacle 77 can be reserved for an operator. For this purpose, the receptacle 77 is arranged inaccessible to an unauthorized user. In particular, the tamper switch 66 is actuated in the event of an unauthorized attempt to gain access to the receptacle. The recording can between the first board 60 and the second board 61, z. B. on an underside of the first circuit board 60 can be arranged.

In order for the security system 1 to be functional, a mother module 801 must be arranged in a receptacle 77 of the security system 1 . The mother module 801 must remain in the receptacle 77 so that the safety system 1 remains functional for longer than the specified time interval.

Each emergency button 10, 10', 1010, 1010', 2010, 2010', 3010 includes a receptacle 77. Precisely one mother module 801 is required and provided for each first bus system 400, 400' of the security system 1. The emergency button 10, 10', 1010, 1010', 2010, 2010', 3010 is only used if the mother module 801 is inserted into the receptacle of an emergency button 10, 10', 1010, 1010', 2010, 2010', 3010 as a control device 100 for the corresponding first bus system 400, 400'. The other emergency buttons 10, 10′, 1010, 1010′, 2010, 2010′, 3010 of the security system 1, in whose receptacle there is no mother module 801, the same program codes as in the control device 100 are stored. Without the mother module 801, however, the program codes are not enabled, so that the other emergency buttons 10, 10', 1010, 1010', 2010, 2010', 3010 cannot serve as the control device 100. Because the mother module 801 is located in the receptacle 77, the emergency button 10, 10', 1010, 1010', 2010, 2010', 3010 serves as a control device 100.

If the control device 100 is to be designed separately from the emergency buttons 10, 10', 1010, 1010', 2010, 2010', 3010 and the door locks 200, 200', 1200, 1200', 2200, 2200', 3200, then a mother module 801 inserted into a receptacle 77 of the processing electronics 101. Because the mother module 801 is located in the receptacle 77, the processing electronics 101 are able to carry out the functions of the control device 100.

If the security system 1 includes a plurality of subsystems 5, 6 and thus a plurality of first bus systems 400, 400', then the security system 1 includes exactly the same number of mother modules 801, 801' as there are subsystems 5, 6 (see Fig. figure 10 ). The emergency button 10', which communicates with the mother module 801', and the processing electronics 101 of the control device 100 off figure 10 , which communicates with the mother module 801, are also provided in order to be connected to the second bus system 401.

The mother module 801, 801' can contain 5.6 different codes for each subsystem and thus enable different functions. So e.g. B. the mother module 801 'of the second subsystem 6 include a code for the selective assignment of the door locks 200', 1200', 2200' to the emergency buttons 10', 1010', 2010'. On the other hand, the code for a selective assignment of door locks to emergency buttons on the mother module 801 for the subsystem 5 is not necessary.

The communication module 801, 801′, 802 can have a gap 803 through which a tape, in particular a self-adhesive tape, is guided. The self-adhesive tape is used to manually remove the communication module 801, 801', 802 from the receptacle 77. The self-adhesive tape includes information about the functions that can be unlocked using the codes stored on the respective communication module 801, 801', 802. The information can be a color identifier, a QR code and/or a bar code.

Alternatively, the communication module 801, 801', 802 can be in the form of a chip card with a flexible section. Part of the chip card protruding from the exception 77 can be provided with the information, i. H. color code, QR code and/or bar code.

A mother module 801 that has been used once in a security system 1 can be functionally used again in a receptacle 77 of another security system 1 according to the invention.
