Description

The invention relates to a safety system for unlocking at least one door lock, in particular for securing escape routes, the safety system comprising a triggering element, in particular an emergency button, the triggering element comprising a manually actuable actuating element, wherein an actuation signal for unlocking the door lock can be generated by actuating the actuating element . The invention also relates to a method for unlocking at least one door lock, in particular for securing escape routes, with a triggering element, in particular an emergency button, comprising a manually operable actuating element, and actuation of the actuating element generates an actuating signal for unlocking the door lock. Furthermore, the invention relates to a use of the security system according to the invention.

Security systems for securing escape routes are known. The safety systems include at least one latching emergency button and a door lock. If the actuating element of the emergency button is actuated, the actuating element remains in an actuating position. In the actuation position, a circuit is broken so that a door lock is transferred to an unlocked state. If a locked state of the door lock is to be restored, an operator, i. H. authorized person, manually return the emergency button on site by rotating the actuating element from the actuating position to a starting position.

According to the DIN EN 13637 draft, it is also permitted to use non-locking release elements. The problem here is that the door lock can lock again despite the ongoing danger and the escape route can no longer be available to the fleeing people.

It is therefore the object of the invention to specify a safety system and a method for unlocking at least one door lock which also ensures the safety of the safety system using a non-locking actuating element.

This object is solved by a security system according to independent claim 1 . Advantageous developments of the security system are specified in the dependent device claims, the description and in the figures. Furthermore, the invention is also solved by the features of the independent method claim according to claim 15 . Features and details that are described in connection with the security system according to the invention also apply in Connection with the method 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. In particular, a method that can be carried out with a security system according to one of Claims 1 to 14 and/or a safety system with which a method according to Claim 15 can be carried out is protected. Furthermore, use of the security system according to the invention is protected.

Starting from the safety system described at the outset, the previously derived and indicated object is achieved in that the safety system comprises an electronic device and, as a result of the actuation signal, is electronically prevented by the electronic device from being able to actuate a locking mechanism of the door lock for locking without the existence of a cancellation condition. In other words, the actuation signal causes the electronic device, in particular in the electronic device, to electronically prevent a locking mechanism of the door lock from being controllable for locking without the presence of a cancellation condition. Thus, activation of the locking mechanism for locking is prevented until the cancellation condition is reached. The result of this is that after the actuation element has been actuated to unlock the door lock, locking of the door lock is reliably prevented. The safety of the safety system can thus be ensured by the fact that, in particular as a result of the actuation signal, it is electronically prevented that the locking mechanism is actuated for locking without the cancellation condition being reached. Because the prevention takes place electronically, the security of the security system can be guaranteed in a simple manner. In particular, no additional mechanical components are required and/or the electronic prevention is static. "As a result of the actuation signal" means here in particular that after the actuation signal has been generated, re-locking is prevented, regardless of whether the actuation signal continues to be generated or not.

After the cancellation condition has been reached, the safety system allows activation for locking again. It may be that after the cancellation condition has been reached, the locking mechanism is activated for locking. In this case, in particular, the locking mechanism is actuated immediately and automatically for locking after the cancellation condition has been reached. In particular, the achievement of the override condition causes the locking mechanism to be actuated to lock. Thus, always through that Reaching the cancellation condition, the door lock is transferred to the locked state.

Locking is understood to be the transfer of the door lock into the locked state. Unlocking is understood to mean the transfer of the door lock into the unlocked state.

The security system may include the locking 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. a locking element, d. H. a bolt or door latch, which is in a retracted position in the unlocked state of the door latch. In the retracted position, the latch member is 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 implemented by turning 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 security system may include the door lock control but not the locking mechanism. In this case, the door locking control is designed as a door locking adapter. The door locking adapter serves to use the security system according to the invention with locking mechanisms that have already been installed.

The door lock includes the locking mechanism and, if equipped, the door lock controller. The security system particularly preferably includes the door lock.

The door latch or locking mechanism can be integrated into a mechanical lock.

In the following, a distinction is made between a user and an operator. 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. An operator serves to operate the security system. The operator has access to a monitoring device of the security system and/or can authenticate himself to the security system, in particular in order to operate the security system. The guard device can be designed as a PC or a monitor. By the operator z. B. the cancellation condition can be met. As an actuation signal is im The following is understood to be the signal generated by the user by actuating the actuating element in order to unlock the door lock and clear the escape route.

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.

The triggering element is preferably designed as 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. formed as a door handle.

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.

It can be provided that the actuation of the actuation element can be carried out in such a way that the actuation element can be moved from an initial position into an actuation position. Thus, the actuating element is mechanically movable. The actuation signal is preferably generated in the actuation position. This can do that Actuator give the user feedback on the operation in a simple way.

It is also conceivable that after actuation, the actuating element can always be moved from the actuating position into the starting position without manual action, preferably by a restoring means. The actuating element can be z. B. be moved to the starting position after activation of the restoring means or immediately after the end of the manual operation. The restoring means can be a spring. Additionally or alternatively, the actuation element can always be actuated mechanically without locking. During actuation, the actuation element can remain in the initial position or be moved into the initial position immediately after the end of the manual actuation. The result of this is that the actuating element can be actuated again even without a manual return of the actuating element. The renewed actuation of the actuating element can only unlock the door lock if the door lock is not already in the unlocked state. If the door lock is already in the unlocked state and the actuating element is actuated, the locking mechanism in particular is not actuated. The door lock remains in the unlocked state.

The actuating element preferably has an illuminated area. The illuminating area is preferably provided in the center of the actuating element. Light of one color, in particular red light, is always emitted with the aid of the illuminating area. A light source located behind the actuator may shine through the illuminating area.

Provision can be made for a first program code to be stored in the electronic device, the first program code, as a result of the generation of the actuation signal, preventing the locking mechanism from being able to be actuated for locking without the cancellation condition being present. In this way, the goal according to the invention can be achieved in a particularly simple manner. In particular, the first program code is stored in a first digital processing means of the electronic device. A second program code can be redundantly stored in a second processing means of the electronic device. As a result of the generation of the actuation signal, the first program code and the second program code can prevent the locking mechanism from being controllable for locking without the existence of the cancellation condition. This achieves a one-fault security.

The first and/or the second processing means can each comprise a processor. The first and/or the second processing means can e.g. B. each as Microprocessors - or be designed microcontroller. The first and/or the second processing means can each comprise a non-volatile memory.

The electronic device can e.g. B. in the trigger element, especially in the emergency button. Particularly preferably, however, door locking, in particular in the door locking control, comprises the electronic device. In this way, as a result of the actuation signal, the door locking controller prevents the locking mechanism from being able to be actuated for locking without the existence of a cancellation condition. This prevents locking in the event of danger where the safety-relevant activation of the locking mechanism is carried out.

The door lock controller may include the first and second digital processing means. The first and the second processing means are used to control the locking mechanism independently of one another. This achieves redundancy.

The triggering element, in particular the emergency button, can include an electronic unit. The electronics unit serves as a trigger element control. The electronics unit can include a first and a second digital triggering element processing unit, in particular a first and a second emergency button processing unit. The first and/or the second trigger element processing unit can each comprise a processor. The first and/or the second triggering element processing unit can be in the form of a microprocessor or microcontroller. The first and second trigger element processing units may each include non-volatile memory. In addition, the electronics unit may include a third digital trigger element processing unit.

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 then, independently of one another, trigger the activation of the door locking mechanism for unlocking via the first bus system. In particular, at least one message in which the first and/or the second trigger element processing unit provides information about the presence of the first or second actuation signal is sent to the door lock controller via the first bus system. In this case, in particular, the first triggering element processing unit informs the first processing means and the second triggering element processing unit informs the second processing means. In this way, in particular, both the first and the second processing means actuate the locking mechanism for unlocking, ie switch off the electrical power supply.

A sign-of-life signal from the first and second trigger element processing units is preferably regularly sent to the door lock controller. In this case, the first and the second triggering element processing unit in particular each emit their own sign-of-life signal. The sign-of-life signals can be contained in a message. The first processing means checks the sign of life of the first triggering element processing unit and the second processing means checks the sign of life of the second triggering element processing unit. If one of the sign-of-life signals fails to appear one or more times, the first and second processing means activate the locking mechanism for unlocking. Here, one processing means can inform the other processing means about the absence of the sign of life.

Until the cancellation condition is met, the triggering element can store electronically that an actuation signal, in particular the first and the second actuation signal, has been generated. In particular, the triggering element electronically stores in the first triggering element processing unit and redundantly in the second triggering element processing unit that an actuation signal has been generated. The storage can take place in the non-volatile memories of the first and the second trigger element processing unit. In particular, the first trigger element processing unit stores that the first actuation signal has been generated and the second trigger element processing unit that the second actuation signal has been generated. This ensures that the safety system does not forget to actuate the actuating element.

The door latch controller may electronically store that an actuation signal has been generated until the override condition is met. In particular, the door lock controller electronically stores in the first processing means and redundantly in the second processing means that an actuation signal has been generated. The storage can take place in the non-volatile memories of the first and second processing means.

The fact that an actuation signal has been generated is preferably stored both in the triggering element and in the door locking control.

In order to achieve a particularly high level of security, the triggering element repeatedly sends a signal to the door locking controller until the cancellation condition is met, stating that an actuation signal has previously been generated. The signal is preferably always sent together with a sign-of-life signal until the cancellation condition is met. In this case, the first triggering element processing unit can repeatedly override the first processing means until the cancellation condition is met inform that the actuation signal has been generated and the second trigger element processing unit can inform the second processing means accordingly. The information can be contained in a message that is sent via the first bus system.

It may be that the first trigger element processing unit always sends the safety-relevant message, e.g. B. sends the message about the presence of an actuation signal, the sign of life or the signal that the actuation signal has previously been generated to the door lock controller. The message includes the information of the first and the second trigger element processing unit.

Provision can be made for the electronic device to include an electronic determination, it being possible for the electronic determination to be converted into an actuation state as a result of the actuation signal. When the cancellation condition is reached, the electronic determination can be transferred to an initial state. In the actuated state, the electronic determination prevents the locking mechanism from being commanded to lock. In the initial state, the electronic determination allows the locking mechanism to be commanded to lock. When the cancellation condition is reached, the electronic determination is transferred to the initial state. The prevention of the locking after the generation of the actuation signal is achieved in a particularly reliable and simple manner by the electronic determination.

The electronic statement may include a variable in addition to the first program code. The first program code includes the variable or has access to the variable. In an initial state of the electronic determination, the variable is set to an initial value. In the actuation state, the variable is set to an actuation value that prevents the door latch from being locked. The variable can be binary. If the override condition is met, the value of the variable is set to the initial value. The first program code captures the value of the variable and allows the door lock to be locked when the value of the variable is equal to the initial value and prevents the door lock being locked when the value of the variable is equal to the actuation value. The variable is stored in the non-volatile memory of the first processing means. The second program code proceeds correspondingly with the variable that is redundantly stored in the non-volatile memory of the second processing means.

The variable may be stored in the first and in the second trigger element processing unit. The variable can be repeatedly transmitted from the trigger to the door lock controller.

If the variables that the first and the second triggering element processing unit transmit to the door locking controller do not match, then in particular activation of the locking mechanism for locking is not permitted. If the variables that have been stored by the first and the second processing means do not match, then in particular an activation of the locking mechanism for locking is not permitted. To this end, the first and the second processing means communicate with one another.

Provision can preferably be made for a number of door locking controls and a number of triggering elements to be connected to one another via the first bus system and for the number of door locking controls to be assigned to the number of triggering elements in such a way that when one of the triggering elements is actuated, only the at least one door locking control associated with the actuated trigger element is assigned, controls the respective door locking mechanism for unlocking. Through the assignment, a selective unlocking of the door locks is provided. Thus, when one of the triggering elements that are connected to the first bus system is actuated, not all door locking controls that are connected to the first bus system are prompted to activate the respective door locking mechanism for unlocking, but rather only those door locking controls that have previously been assigned to the actuated triggering element are. The remaining door lock controls that have not been assigned to the actuated trigger element refrain from triggering the respective door lock mechanism for unlocking. This makes it possible to arrange the door locks, which are connected to the first bus system, on different doors. If the trigger element is actuated, z. B. only open the door on which the trigger element is arranged. The other doors remain closed. If the actuation signal is generated at a triggering element of such a safety system, only the at least one door locking controller assigned to the actuated triggering element is electronically prevented from being able to actuate the corresponding locking mechanism for locking until the cancellation condition is met. However, the door locking controls of the first bus system that are not assigned to the actuated triggering element remain lockable.

A cancellation signal can be used to achieve the cancellation condition, with the cancellation signal being able to be generated by a cancellation action carried out directly on the triggering element. The result of this is that the operator goes to the triggering element and is convinced on site that there is no longer any danger. The cancellation action can take place at least by touching the triggering element or by near-field communication.

The cancellation action, which is carried out directly on the triggering element, can be generated by actuating the actuating element. As a result, the actuating element already provided for releasing the escape route is used in a practical manner. A further element on the triggering element can thus be dispensed with and, to a particular extent, the operator can go to the triggering element.

It may be that the override condition is achievable without rotating the actuator. The overriding action on the trigger element can be performed without rotating the actuating element. In particular, it is conceivable that the actuating element can only be moved in a translatory manner. In particular, the actuating element can only be moved between the starting position and the actuating position.

It is conceivable that the cancellation signal corresponds to the actuation signal. Thus, the same action used to generate the actuation signal to unlock the door latch can also serve as the override action.

In order for the electronic device to recognize that the actuating element is actuated to achieve the cancellation condition and not to generate the actuating signal for releasing the escape route, the electronic device must have additional information.

It may be that the security system comprises an authentication device assigned to the triggering element or is in communication with the authentication device assigned to the triggering element. Communication can be wired or wireless.

Authentication at the authentication device can take place, for example, by entering a code, transmitting a code wirelessly or by cable, recognizing a key by turning it, recognizing personal features such as fingerprints or irises. The authentication device can be designed, for example, as a keypad, as a key switch, as a fingerprint sensor or as a reader. The authentication device can be associated with one or more triggering elements. The authentication device is preferably assigned to only one triggering element.

After successful authentication, the electronic device receives a positive identification signal about the authentication at the authentication device.

It is conceivable that the authentication device, if there is no danger, is used to cause an authorized person to unlock the door lock. Here, a control device of the security system can receive a positive authentication signal from the authentication device and cause the unlocking of the door lock.

In order to achieve the cancellation condition, authentication can take place at the authentication device, in particular a positive identification signal can be received by the triggering element. In order to achieve the cancellation condition, it may be that both the cancellation signal has been generated and the authentication at the authentication device, in particular the receipt of the positive identification signal, has taken place.

In order to achieve the cancellation condition, it may be necessary to comply with a predetermined time sequence when generating the cancellation signal and the authentication, in particular the receipt of the positive identification signal. In addition or as an alternative, it can be the case that, in order to achieve the cancellation condition, a predetermined sequence must be observed when generating the cancellation signal and the authentication, in particular the receipt of the positive identification signal. The generation of the cancellation signal and the authentication that has taken place, in particular the generation of the cancellation signal and the authentication that has taken place, in which the time sequence and/or the sequence is observed, can be sufficient to achieve the cancellation condition and thus at least allow the locking of the door lock.

In particular, the cancellation signal and the authentication, in particular the receipt of the positive identification signal, must be present at least partially simultaneously. The authentication, in particular the receipt of the positive identification signal, must preferably last longer than the generation of the override signal.

For example, in order to achieve the cancellation condition, it may be sufficient for the actuating element to be actuated first and, while the actuating element remains actuated, to turn a key in the key switch. The key remains turned while the actuator is released.

In another example of achieving the override condition, it may be sufficient that the key is first turned in the key switch and then the actuating element is actuated while the key remains turned. The key remains turned while the actuator is released.

It may be that the override signal generated by an action taken directly on the trigger element is always necessary to achieve the override condition. It may alternatively be that the override signal generated by an action taken directly on the trigger element only is then necessary to achieve the cancellation condition if the door was opened after generating the actuation signal. For this purpose, the security system, in particular the electronic device, can have a signal from at least one door status monitoring device. A door can also be understood to mean a door leaf.

The door status monitor is for detecting whether the door is open or closed. The door status monitoring device can be e.g. B. be a door contact, a sensor, a switch and / or a door lock with detectable bolt and / or latch position. The security system may include the door condition monitoring device or be connectable to the door condition monitoring device.

At least a first door status monitoring device and a second door status monitoring device are particularly preferably provided for a door, in particular for a door leaf, and/or a door lock. In this way, one-fault security can be achieved. The first door status monitoring device preferably differs in its design from the second door status monitoring device. As a result, the error security is increased.

1. a.) seit dem Erzeugen des Betätigungssignals kein Signal der Türzustandsüberwachungsvorrichtung über das Öffnen des Türblatts innerhalb des vorbestimmten Zeitintervalls in dem Sicherheitssystem, insbesondere von der Elektronikvorrichtung, empfangen worden ist und
2. b.) das vorbestimmte Zeitintervall verstrichen ist.

In particular, if the door, in particular the door leaf, remains closed after the activation signal has been generated, the safety system has at least one further possibility of achieving the cancellation condition. For example, it may be sufficient in this case that a predetermined time interval, z. B. 60 s has elapsed since the generation of the actuation signal. In the expression "since the generation of the operation signal", a time to notify the electronic device of the operation signal can be neglected. The predetermined time interval can be stored in the electronic device. Thus, to meet the override condition, it may be sufficient if

1. a.) since the activation signal was generated, no signal has been received from the door status monitoring device about the opening of the door leaf within the predetermined time interval in the security system, in particular by the electronic device, and
2. b.) the predetermined time interval has elapsed.

The electronic device can include a timer for determining the time interval.

The predetermined time interval can be permanently specified and stored in the electronic device in an unchangeable manner. Alternatively, an operator the predetermined

Set the time interval using a parameterization program. Here, a minimum time can be fixed.

1. a.) weder ein Signal von der ersten Türzustandsüberwachungsvorrichtung noch von der zweiten Türzustandsüberwachungsvorrichtung, die für ein Türblatt und/oder eine Türverriegelung vorgesehen sind, über das Öffnen des Türblatts seit dem Erzeugen des Betätigungssignals innerhalb des vorbestimmten Zeitintervalls in dem Sicherheitssystem, insbesondere von der Elektronikvorrichtung, empfangen worden ist.

If the first and the second door status monitoring device are provided, the condition a.) can deviate from that

1. a.) neither a signal from the first door status monitoring device nor from the second door status monitoring device provided for a door leaf and/or a door lock about the opening of the door leaf since the actuation signal was generated within the predetermined time interval in the security system, in particular from the electronic device , has been received.

Provision can be made for the security system to include a central escape route control, it being possible for a cancellation signal to be generated at the central escape route control. The cancellation signal or a message about the cancellation signal can be sent to the electronic device via at least one bus system, in particular at least via a second bus system. The override signal can be used to achieve the override condition. In particular, authentication of an operator at the central escape route control is necessary to generate the cancellation signal. For this purpose, the escape route control can comprise an identification device. The authentication at the central escape route control can be done by entering a code, wireless or wired transmission of a code, recognizing a key by turning it, recognizing personal features such as fingerprints or irises. For example, the central escape route control can include a keypad, a key switch, a fingerprint sensor or a reader as an identification device.

The identification device preferably has at least one additional function. The central escape route security can include a central emergency button. If the central emergency button is pressed, the locking mechanism is actuated for unlocking.

The process whereby the locking mechanism is actuated for unlocking as a result of pressing the central emergency button is single-fault-safe and is therefore suitable for emergencies. If the central emergency button has been actuated, the electronic device preferably electronically prevents the locking mechanism of the door lock from being controllable for locking until a corresponding signal has been generated by the identification device via authentication and the signal or a message about the signal from the Electronic device has been received.

In particular, if automatic re-locking after the predetermined time interval has elapsed with the door remaining closed is not felt to be safe enough, it is conceivable that, in addition to conditions a) and b), the following additional condition is provided for achieving the cancellation condition:
c.) the cancellation signal is generated at the central escape route control.

Conditions a.) to c.) may be sufficient to achieve the cancellation condition.

It is preferably conceivable that a permissible cancellation signal, which contributes to the achievement of the cancellation condition, can only be generated after the predetermined time interval has elapsed. On the other hand, authentication at the central escape route control within the predetermined time interval does not lead to a permissible cancellation signal that contributes to the achievement of the cancellation condition. It may be that the elapse of the predetermined time interval can be displayed visually at the central escape route control. For this purpose, the central escape route control can include lamps with which, in particular, a delay in the unlocking as a result of the actuation of the triggering element can also be displayed. The central escape route control can include an emergency module. In addition to the central emergency button and the identification device, the emergency module can include the lighting means.

If the door lock was unlocked due to a fire alarm signal and the door was then not opened, which is to be detected in particular by both the first and the second door status monitoring device, after the end of the fire alarm signal, authentication at the identification device can also lock the door locking be initiated. Only when the fire alarm signal has already ended does authentication on the identification device result in locking again. To do this, the door lock controller receives a signal about the authentication. It may be that the possibility of locking the door lock after the end of the fire alarm signal by authentication on the identification device can be displayed visually on the central escape route control. In particular, the same lighting means are used for this purpose.

It is conceivable that the triggering element includes illuminants on site. The lighting means of the triggering element on site can be used to visually indicate whether the presence of a fire alarm signal or actuation of the actuating element electronically prevents the locking mechanism of the door lock from being able to be controlled for locking without the existence of a cancellation condition. Preferred the lamps can indicate in different ways whether re-locking is prevented by the presence of a fire alarm signal or by actuation of the actuating element.

It is also conceivable that the lighting means of the triggering element can be displayed on site, that relocking is prevented by actuating the central emergency button. In particular, the lighting means of the triggering element can show in different ways on site whether the central emergency button has been actuated or the actuating element has been actuated on site. In this way, the operator can find out whether relocking can be produced by an on-site cancellation action or by operating the identification device.

In particular, a door opening signal after the predetermined time interval has elapsed or after the fire alarm signal has ceased does not prevent the override condition from being met.

It may be that the conditions a.) and b.) or a.) to c.) are not sufficient to achieve the cancellation condition and thus allow locking of the door lock. Rather, it may be that the cancellation condition is only met if it is also stored electronically in the security system that the existence of conditions a.) and b.) is permissible for the fulfillment of the cancellation condition and/or it is stored in the security system that the conditions a.) to c.) to achieve the cancellation condition is permissible.

The deposit of the admissibility of can be made by an operator. Permissibility can be stored with the help of a parameterization program. In the parameterization program, the operator can set manually whether the conditions a.) and b.) and/or the conditions a.) to c.) are permissible for achieving the cancellation condition. It may be that the deposit may only take place when the security system is put into operation.

If the safety system includes several triggering elements, it can be stored individually for each triggering element or for groups of triggering elements as to whether the existence of conditions a.) and b) and/or the existence of conditions a.) to c.) is permissible for achieving the cancellation condition is. The group of triggering elements can in particular include the triggering elements that are associated with a door or a door lock. Permissibility is preferably stored electronically in the respective triggering elements.

If the security system includes several door locks, it can be stored individually for each door lock or for groups of door locks, whether

the existence of conditions a.) and b) and/or the existence of conditions a.) to c.) is admissible in order to achieve the cancellation condition. The group of door locks can include, in particular, the door locks that are assigned to a door or a door leaf. Permissibility is preferably stored electronically in the respective door locks.

Before the locking mechanism is actuated for locking, the electronic device checks whether the conditions a.) and b.) and/or the conditions a.) to c.) have been stored as permissible. If the conditions a.) and b) and/or the conditions a.) to c.) have not been stored as permissible, the locking is not permitted or the locking mechanism is not activated for locking. Thus, in order to meet the cancellation condition, it may be sufficient
the conditions a.) and b.) are fulfilled and it is deposited that the existence of the conditions a.) and b.) is permissible for the achievement of the cancellation condition.

Alternatively, in order to achieve the cancellation condition, it may be sufficient that
the conditions a.) to c.) are fulfilled and it is deposited that the existence of the conditions a.) to c.) is permissible for the fulfillment of the cancellation condition.

So it may be that the security system z. B. includes a first trigger element, in which always on site, d. H. by generating the override signal and authenticating that the override condition must be met regardless of whether or not the door has been opened since the actuation signal was generated. Any other reaching is not permitted. In a second triggering element of the safety system, if the door has remained closed since the actuation signal was generated, the cancellation condition can be achieved by the predetermined time interval having elapsed and the eligibility for this having been deposited. In the case of a third triggering element of the safety system and the case that the door has remained closed since the actuation signal was generated, the elapse of the predetermined time interval is not sufficient for the cancellation condition to be reached. Rather, the cancellation signal must also have been generated at the central escape route control after the predetermined time interval in order to achieve the cancellation condition, and this possibility of achieving the cancellation condition must have been stored as permissible.

If the conditions for achieving the cancellation condition are stored for the triggering element and/or in the triggering element, it may be that the electronic device asks the triggering element in which the actuating signal was generated before activating the locking mechanism for locking, whether the fulfilled conditions present in the electronic device are stored in the triggering element as permissible for achieving the cancellation condition.

The security system can include several central escape route controls. The central escape route controls can each include an identification device. In this case, it can be stored in the security system at which identification device a cancellation signal that is permissible for fulfilling condition c.) can be generated. This can be stored individually for a number of triggering elements and/or a number of door locks.

The triggering element can be brought into a deactivated state. In the deactivated state, as a result of an actuation of the actuating element, the locking mechanism for unlocking the door lock is not activated. The triggering element can be brought from the deactivated state into the activated state. In the activated state, as a result of an actuation of the actuating element, the locking mechanism is actuated to unlock the door lock. The deactivated state can e.g. B. at night in a department store or in a closed ward of a psychiatric ward. In particular, the triggering element can be brought into the deactivated and/or activated state by the central escape route control.

It is preferably provided that in the activated state of the triggering element a previously performed actuation of the triggering element in the deactivated state has no effect on the actuation of the locking mechanism. This prevents the door lock from being unlocked immediately during or after the transition to the activated state, although the actuating element was actuated hours or days previously when the triggering element was in the deactivated state. This is particularly advantageous for the present non-locking release element.

The security system is preferably designed to indicate an actuation of the actuating element in the deactivated state of the triggering element at a control center. This allows an operator to identify a hazard to the user and act accordingly. The operator can transfer the trigger element into the activated state or unlock the door lock. In particular, the control center is the central escape route control or the guard device.

A functioning of the central escape route control and/or the connection of the central escape route control to the control device is monitored in the deactivated state of the triggering element. If an error occurs, the triggering element is transferred to the activated state. This can increase security on site if activation or unlocking can no longer be carried out via the control panel.

The emergency button can have an at least partially transparent covering means. When the actuating element is actuated, the covering means can be moved from an initial position into an actuating position. The covering means can cover the actuating element, so that the actuating element is actuated via the covering means. The covering means serves to build up an imaginary barrier to the actuation of the triggering element and thus to counteract abusive actuation. The conceptual barrier arises because the user thinks he has to destroy or remove the covering means before the user can actuate the triggering element.

Provision can be made for the covering means to be arranged so that it cannot be removed. Due to the fact that the covering means is arranged so that it cannot be removed, the covering means cannot be removed. As a result, the emergency button remains as originally designed and built. In particular, the covering means is transparent in such a way that the actuating element can be seen by the user through the covering means. The actuating element is preferably actuated indirectly via the covering means. "Removable" means in particular that the covering means cannot be removed or opened to generate the cancellation signal.

The non-removable arrangement in the triggering element is made possible in particular by the fact that the operator does not have to turn the actuating element in order to achieve the cancellation condition. The non-removable arrangement can thus be made possible in particular by the electronic prevention of the locking mechanism for locking the door lock being able to be activated without the existence of a cancellation condition.

The non-removable arrangement of the covering means can be designed in various ways. For example, the covering means may be mounted in an undetachable manner. The covering means can thus be guided in the emergency button in a particularly movable manner. Additionally or alternatively, the covering means can be made of an elastic material. For example, the covering means can comprise an elastic foil which is stretched over the actuating element. As a result, the covering means can contribute to the watertight design of the emergency button. In addition or as an alternative, the covering means can be firmly connected to the actuating element. The connection is designed in particular in a form-fitting or material-locking manner. As a result, misuse can be prevented, with the actuating element in particular being movable only together with the cover element.

The security system according to the invention is particularly suitable for use in a building in which people with an impaired mental state live, in particular in a psychiatric ward, a dementia ward or the like. In particular through the possibility of deactivation, monitoring and, if necessary, activation can thereby increase the safety of the occupants.

The object of the invention is also achieved by a method for unlocking at least one door lock, in particular for securing escape routes. In the method, a triggering element, in particular an emergency button, includes an actuating element that can be actuated manually. By actuating the actuating element, an actuating signal for unlocking the door lock is generated. As a result of the actuation signal, an electronic device electronically prevents a locking mechanism from being activated for locking without the existence of a cancellation condition.

a schematic representation of a process of enabling a function in a security system according to the invention.

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 prompts 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 briefly holds the ID card in front of the reader or if the user briefly turns the key, 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 to 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 aid 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 ended. 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 with 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 is to 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. 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 other 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 time stored for the emergency button 2010', the emergency button 2010' delays the unlocking from the moment the delay element 332 is actuated 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.II 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 between 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 from 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 and 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, 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 carried out by the emergency button 10, which is connected to the control device 100 via the first bus system 400, 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.
