Description

The invention relates to a security system for controlling and/or monitoring door locks for securing escape routes. The security system includes door locking controls, with a door locking control being used to control a locking mechanism that is to be assigned to the door locking control. The safety system comprises triggering elements, in particular emergency buttons, whereby actuation of a triggering element can trigger at least one locking mechanism, according to the preamble of patent claim 1. The invention also relates to a method according to independent patent claim 15.

Security systems with an emergency button for securing escape routes are known. When the emergency button is actuated, a door lock is unlocked so that a user can flee in the event of danger. Here, the emergency button and the respective door lock(s) that should be unlocked when the emergency button is pressed are electrically connected to each other. If the emergency button is pressed, the power supply between the door lock and the emergency button is interrupted, which unlocks the door lock.

From the EP 2 725 172 A2 it is known to connect an emergency button and a door lock to one another via a bus system. In this case, only one door lock is connected to a bus system. A separate bus system is therefore required for each door.

It is therefore the object of the present invention to provide a security system and a method which, in particular, enable escape route protection for a number of doors in a simple and/or material-saving manner.

This object is solved by a security system according to independent claim 1 . Advantageous developments of the security system are specified in the dependent claims, the description and in the figures. The features mentioned in the description and in the claims can each be essential to the invention individually or in combination.

Based on the safety system described at the outset, the previously derived and indicated object is achieved in that a number of door locking controls and a number of triggering elements are connected to one another via a common bus system and the number of door locking controls are assigned to the number of triggering elements in such a way that when actuated one of the triggering elements, only the at least one door locking control that actuates the Release element is assigned, controls the respective locking mechanism for unlocking.

The security system includes the common bus system. The common bus system is referred to below as the 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 subscriber of the bus system with its own bus address.

The security system includes multiple trigger elements and multiple door lock controls. In this case, a first number m of triggering elements and a second number m' of door locking controls are connected to the first bus system. Here, m and m' correspond to a natural number of at least two, preferably at least three, particularly preferably at least four. In one example, n is four. The first number m can be the same as the second number m' or different from the second number m'. According to the invention, a selective unlocking of the door locks is provided. As a result of the actuation of one of the triggering elements that are connected to the first bus system, not all door locking controls that are connected to the first bus system are prompted to activate the respective locking mechanism for unlocking, but only those door locking controls that were previously assigned to the actuated triggering element have been. The other door locking controls that have not been assigned to the actuated trigger element refrain from triggering the respective locking 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. It is also possible to assign the door locking controls to a triggering element in such a way that multiple doors can be opened when the triggering element is actuated. For this purpose, only a corresponding number of door locking controls must be assigned to the triggering element. Because the door lock controls and the triggering elements are connected to one another via the first bus system, a material-saving option has been created for selectively unlocking door locks.

It is also possible to assign all door locking controls to at least one trigger element, in particular all trigger elements. In this case there is no need for selective unlocking when the trigger element is actuated.

At least, however, the security system according to the invention allows the operator of the security system to choose whether selective unlocking is desired or not.

The triggering element can comprise a manually operable actuating element. As a result of the actuation of the actuation element, an actuation signal can be generated.

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. designed as a door handle.

Locking is understood to be the conversion of a door lock or a locking mechanism into a locked state. Unlocking is understood to be the transfer of a door lock or a locking mechanism into an unlocked state.

At least one latch mechanism is associated with each door latch controller. For example, exactly one locking mechanism can be assigned to each door locking control. Each door latch includes a door latch controller and a latch mechanism.

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

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

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

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

Switching off the electrical power supply preferably leads to an unlocked state of the door lock. The locking mechanism for unlocking the door lock is thus activated by switching off the electrical power supply. Switching on the electrical power supply preferably leads to a locked state of the door lock. Thus, the control of the locking mechanism for locking is implemented by switching on the electrical power supply. The door lock control controls the respectively assigned locking mechanism for locking and unlocking. To do this, the door lock controller can switch the electrical power supply for the locking mechanism on and 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 safety system can be designed without at least one of the locking mechanisms. In this case, the respective door locking control only controls the locking mechanism. For example, the door latch controller turns on or off the electrical power supply to the latch mechanism, or causes the electrical power supply to be turned on or off. The security system may include at least one door lock controller whose associated locking mechanism is not included in the security system. 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 security system particularly preferably includes the door locks.

At least one of the door lock or the locking mechanisms can be integrated in 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.

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 can trigger activation of the locking mechanism for unlocking. Initiating an activation is understood in particular as meaning the sending of a message via the first bus system and/or a 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. 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.

As a result of an actuation, it is understood that an actuation is causal, regardless of whether the actuation persists or not.

The number of door locking controls and the number of triggering elements are assigned to one another. Therefore, it can be said that the door lock controls are associated with the triggering elements as well as that the triggering elements are associated with the door lock controls.

It is provided according to the invention that in the door locking controls belonging to the number of door locking controls, it is stored in each case to which at least one triggering element the respective door locking control is assigned. This makes it possible for the door locking control to decide whether the triggering element, the wants to cause the door lock to trigger the locking mechanism for unlocking, is actually assigned to the triggering element.

For this purpose it can be provided that the triggering elements include a bus address. Each triggering element includes at least one bus address. The bus address of the triggering element can be stored in the at least one door locking controller assigned to the triggering element for assignment. This enables a reliable assignment. In particular, the bus address is stored unchangeably in the respective triggering element. i.e. a user or an operator cannot change the bus address. For example, the bus address cannot be changed by a parameterization program or by a setting option for the triggering element.

It may be that all the door lock controllers of the number of door lock controllers as a result of the actuation of the trigger element are notified of the actuation by the trigger element. All door lock controls of the number of door lock controls are to be understood as meaning all door locks that are connected to the first bus system. The trigger that has been actuated sends a message about the actuation to all door lock controllers of the first bus system. The notified door lock controls decide whether to unlock the locking mechanism associated with the door lock controls. For this purpose, each door locking controller that is connected to the first bus system can check whether the respective door locking controller is assigned to the triggering element sending the message. Only when the door lock controller determines that the door lock controller is assigned to the trigger element sending the message does the door lock controller activate the locking mechanism for unlocking.

Provision is preferably made for the door locking controls to be assigned to the triggering elements only when the security system is put into operation. During commissioning, this means that the assignment takes place before the safety system starts operating. In particular, parameters for the safety system are additionally set during commissioning.

The assignment of the door locking controls to the triggering elements can be done by a conscious action of an operator. The door locking controls can be assigned to the triggering elements via the first bus system. In other words, the first bus system can be involved in the assignment of the door locking controls to the triggering elements. So it may be that in the course of the assignment, a triggering element sends the bus address of the triggering element via the first bus system.

The assignment of the door locking controls to the triggering elements is particularly preferably set directly on the triggering elements and/or on the door locking controls. This can z. B. the assignment only takes place in that the operator for setting the triggering element and/or the door locking controls to be assigned to the triggering element at least sees, in particular physically contacts and/or manually actuates.

For example, when the safety system is started up in an assignment mode of the door locking control, the assignment of the door locking control located in the assignment mode to the triggering element on which the action is performed can take place through a conscious action performed on the triggering element to be assigned. The conscious action to be taken on the triggering element can include an actuation of the triggering element. In particular, the conscious action to be performed on the triggering element can correspond to an actuation of the triggering element. A particularly reliable assignment can be achieved in this way.

According to the invention, the door locking control comprises a first and a second digital processing means. 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 a microprocessor - or microcontroller be formed. The first and/or the second processing means can each comprise a non-volatile memory.

According to the invention, it is stored both in the first processing means and in the second processing means, to which at least one triggering element the respective door locking control is assigned. This achieves redundancy.

It is preferably provided that the locking mechanism can be controlled by the first processing means and redundantly by the second processing means. The triggering element, in particular the emergency button, can include an electronic unit. 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, in particular the first and/or the second emergency button processing unit, can each comprise a processor. The first and/or the second triggering element processing unit, in particular the first and/or the second emergency button processing unit, can be designed as a microprocessor or microcontroller. The first and second trigger element processing units can each have a 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 trigger the activation of the locking mechanism for unlocking independently of one another 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.

The first and the second trigger element processing unit can e.g. B. monitor each other. If an error is detected, the electronics unit, in particular the intact trigger element processing unit, causes the first and the second processing means to trigger the locking mechanism for unlocking.

The first and second processing means can monitor each other. If an error is detected, the locking mechanism for unlocking is controlled at least by the intact processing means.

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.

The first and second processing means communicate with one another when the door lock controller has received a message about the actuation of the trigger element and/or the presence of a fire alarm signal. If only the first processing means or the second processing means determines that the triggering element has been actuated or that a fire alarm signal is present, the determining processing means controls the locking mechanism for unlocking and/or causes the other processing means to also activate the locking mechanism for unlocking.

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, to the door lock control. The message includes the information of the first and the second trigger element processing unit.

In addition to the already described function that the triggering elements cause the associated door locking controls to unlock as a result of an actuation (function a.), at least one of the triggering elements that are connected to the first bus system can perform at least one other function.

The triggering element can be connected to a fire alarm system. The trigger element can receive a fire alarm signal. After receiving the fire alarm signal, the triggering element can trigger at least one locking mechanism for unlocking (function b.). For this purpose, in particular, the triggering element sends a message about the presence of the fire alarm signal to the door locking controller, whereupon the door locking controller activates the locking mechanism for unlocking. In particular, the triggering element sends such a message to all door locking controls that are connected to the first bus system. Preferably, only the at least one door locking controller then triggers the respective locking mechanism for unlocking, which is associated with the triggering element that sent the message.

The triggering element can delay the actuation of the locking mechanism for unlocking as a result of actuation of the triggering element (function c.). In this case, it is provided in particular that the triggering element causes the locking mechanism to be actuated for unlocking with a time delay. In this case, the triggering element can send a message regarding the actuation to the door lock control(s) with a time delay. The message can be sent to all door lock controls of the first bus system, as previously described, or to the at least one associated door lock control can be sent. To determine the time delay, the triggering element can include a timer.

The triggering element can delay activation of the locking mechanism by a first delay time period. It may be that within the first delay period, the triggering element receives a message to delay the actuation of the locking mechanism by a second delay period. It may be that the triggering element uses the timer to determine the first delay period and/or the second delay period. Upon termination of the first or second time delay period, the triggering element can cause the locking mechanism to be actuated for unlocking. Of course, only the locking mechanisms whose door locking controls are assigned to the triggering element are activated.

The security system can include a central escape route control. The central escape route control is intended to be located remotely from the release element and/or the door lock. In particular, the central escape route security is intended to be arranged in a guard room. In the guard room there can also be a guard device, e.g. B, a monitor or personal computer for monitoring.

The central escape route control is connected in particular to a second bus system. Participants in the first bus system and the central escape route control can communicate with one another via the first and the second bus system.

The extension of the time delay by the second extension period can be initiated by the central escape route control. In particular, the central escape route control can include a delay element. As a result of the operation of the delay element, the trigger element can receive the message to delay the actuation of the locking mechanism by a second delay period. In particular, the triggering element then ends the first delay period and starts the second delay period.

It is conceivable that the triggering element can be transferred from an activated state to a deactivated state. In the deactivated state, a locking mechanism for unlocking is not activated as a result of an actuation of the triggering element. In the activated state, as a result of actuation of the triggering element, the locking mechanism is actuated for unlocking. Thus, in the deactivated state of the triggering element, it is prevented that the locking mechanism for unlocking is actuated as a result of an actuation of the triggering element (function d.). This is omitted in the disabled State preferred that the trigger element causes the activation of the locking mechanism for unlocking. This applies in particular to the door locking controls assigned to the triggering element. The deactivation of the trigger element can be initiated by the central escape route control. For this purpose, the central escape route control can include a first operating element. As a result of an operation of the first control element, at least one triggering element of the first bus system can be switched to the deactivated state.

The triggering element can activate an audio and/or video module or cause such an activation (function f.). The audio and/or video module transmits an audio and/or video recording to the guard device. As a result, in the event of danger, the operator in the guard room and the user on site who wants to flee can communicate acoustically and/or the operator in the guard room can see the location in front of the door at which the triggering element was actuated. In particular, the triggering element enables the audio and/or video module as a result of the actuation of the triggering element. The activation can take place at least in the deactivated state. The release is preferably always carried out as a result of the actuation of the triggering element.

It is preferably provided that, as a result of the actuation of the triggering element, it is electronically prevented that a locking mechanism of the door lock can be actuated for locking without the existence of a cancellation condition (function e.). This prevents the door from being locked again in the event of danger, although users still want to flee. Here, in particular, the door lock control can electronically prevent the door lock from being locked again. If the cancellation condition is reached, the door locking control at least permits relocking. In particular, the door lock controller controls the locking mechanism immediately after the override condition is reached.

To achieve the cancellation condition, a cancellation action can take place at the triggering element. The cancellation action, which is carried out directly on the triggering element, can be generated by actuating an actuating element of the triggering element. In particular, the cancellation action on the triggering element corresponds to the actuation of the actuating element to release the escape route. A cancellation signal generated in this way can thus correspond to the actuation signal. In order for the door locking controller to recognize that the actuation of the actuating element takes place to achieve the cancellation condition and not to generate the actuating signal for releasing the escape route, the door locking controller must have additional information. Thus, it may be necessary for an operator to authenticate himself.

An authentication device that is connected or can be connected to the triggering element can be used for this purpose. This can be the authentication. As a result of the authentication, the triggering element can receive a positive identification signal. In order to achieve the cancellation condition, it may be necessary to comply with a predetermined time sequence and/or order when generating the cancellation signal and for the authentication, in particular the receipt of the positive identification signal. In particular, the override signal and the authentication must be present, at least in part, simultaneously.

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. The expiry of a predetermined period of time and the absence of a signal about an opening of the door within the predetermined period of time can contribute or be sufficient to achieve the cancellation condition. In addition, receipt of a cancellation signal from the central escape route control can contribute to the achievement of the cancellation condition. It may also be the case that one of the options for achieving the cancellation condition without a cancellation action on the triggering element must be stored as permissible.

If a triggering element is actuated, the at least one door locking control, which is/are assigned to the actuated triggering element, electronically prevents the corresponding locking mechanism from being controllable 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.

It may be that the central escape route control includes a central emergency button. If the central emergency button is actuated, at least one locking mechanism can be actuated for unlocking as a result of the actuation. The process whereby the locking mechanism is actuated for unlocking as a result of the actuation of the central emergency button is preferably single-fault-safe and is therefore suitable in the event of danger. In particular, as a result of the actuation of the central emergency button, a message regarding the actuation of the central emergency button is sent to at least one door locking controller of the security system, preferably several door locking controllers of the security system, particularly preferably all door locking controllers of the security system. It may then be the case that at least some of the notified door locking controls activate the respective locking mechanism for unlocking.

It is conceivable that as a result of an actuation of the central emergency button, only some of the door locking controls activate the respective locking mechanism for unlocking, while the remaining door locking controls refrain from such activation. Unlocking is thus selective when the central emergency button is actuated. Thus, as a result of the actuation of the central emergency button, activation for unlocking can be omitted at least for one locking mechanism.

For this purpose, it can be stored in the security system, preferably in the door locking controls of the security system, whether unlocking is permitted as a result of actuating the central emergency button. In particular, an operator can make the deposit. For this purpose, the operator z. B. use a parameterization program to set which door lock is to be unlocked as a result of pressing the central emergency button.

If the door lock controller receives a message regarding the actuation of the central emergency button, the door lock controller can first check whether unlocking is permitted as a result of the central emergency button being actuated. Only when unlocking is permitted as a result of the central emergency button being actuated does the door locking control activate the locking mechanism for unlocking. If, on the other hand, unlocking is not permitted as a result of the central emergency button being actuated, the locking mechanism for unlocking is not actuated. This procedure is particularly useful when all door locking controls of the security system are notified of the actuation of the central emergency button.

It is conceivable that the security system includes several central escape route controls. For example, one of the central escape route controls may be intended for placement in the guardroom. Another central escape route control can be provided for arrangement in a nurse's room. The security system can thus include several central emergency buttons.

There is preferably selectivity with regard to unlocking the door locks as a result of the actuation of the different emergency buttons. It may be the case that it can be stored in the safety system, in particular in the door locking controls, as a result of the actuation of which central emergency button is actuated to unlock the locking mechanism. It may be the case that a specific door locking control activates the locking mechanism as a result of the actuation of a first emergency button and the door lock fails to activate the locking mechanism as a result of the actuation of a second emergency button control unlocking. For this purpose z. B. in the door locking control a list with the central emergency buttons can be stored, as a result of which the locking mechanism is to be controlled for unlocking. For example, the list B. created by an operator in the parameterization program sets the selectivity of the central emergency button to the door locks. This procedure is particularly useful when all door locking controls of the security system are notified of the actuation of the central emergency button of the security system.

It may be that the security system comprises a plurality of bus systems, each of which is connected to a number of triggering elements and to a number of door locking controls, the number of door locking controls being assigned to the number of triggering elements in such a way that when one of the triggering elements is actuated, only the at least a door locking control, which is assigned to the actuated trigger element, controls the respective locking mechanism for unlocking. The multiple bus systems can in particular be of the same type of bus system. The bus system type is in particular the bus system type of the first bus system, e.g. B. a CAN or a DCW bus. The second bus system can be of a different type of bus system, e.g. B. a LON or a LAN bus.

The safety system, in particular the triggering element, can include an acoustic alarm.

The safety system, in particular the triggering element, can include a display device for visually displaying a locking state of the door lock.

A locking state is understood to mean the locked and/or unlocked state of the door lock.

The safety system, in particular the triggering element, can include a display device for optically displaying a time-delayed actuation of the locking mechanism after the triggering element has been actuated.

In this case, both the first and/or the second delay period can be represented visually. The visual representation of the first and second delay periods may differ.

The safety system, in particular the triggering element, can include a display for the visual representation of an alarm condition. The alarm condition can indicate the danger event. The alarm condition occurs in particular after the triggering element has been actuated and/or after a fire alarm signal has been received.

The safety system, in particular the triggering element, can show optically if relocking fails, in particular if the door remains open, which can be detected via the at least one door status monitoring device. One Fire protection doors should always be closed after an inspection. is e.g. If, for example, the door lock was unlocked due to a positive authentication signal and the door was opened but not automatically relocked after the predetermined period of time, this fact can be displayed visually. It can also be displayed visually when a recordable opening time has been exceeded. The opening time can be detected by the door status monitoring device. An operator can choose the open period. The operator can store the opening time using the parameterization program.

As a display device, as a display device, as a display for the visual representation of an alarm condition and/or for the visual representation of the failed re-locking, the triggering element can comprise lighting means. The lighting means preferably serve both as a display device, as a display device, as a display for optically displaying an alarm condition and also for optically displaying the failed re-locking. For this purpose, the lighting means can be controlled in at least two groups. In particular, the lighting means can be controlled individually, at least in part.

Each triggering element preferably has the acoustic alarm transmitter and/or the display device, the display device, the display and/or the lighting means.

The security system can include at least one control device.

It is conceivable that the control device is connected to the first and the second bus system. Subscribers of the first bus system can thus be connected to the central escape route control via the control device.

The control device can control the display device, in particular the lighting means, for the visual display of the locking state and/or cause such a control (function p.).

The control device can control the display device, in particular the lighting means, for the visual representation of the time-delayed control of the locking mechanism and/or cause such a control (function q.). In this case, the control device can have the first and/or the second delay period displayed visually.

The control device can activate the display, in particular the light source for visual display of an alarm condition and/or the acoustic alarm device for the output of an acoustic alarm, or cause such activation (function above and/or function right).

The control device can issue a visual or acoustic alarm if relocking fails, especially if the door remains open (see function).

The control device can activate the acoustic alarm device or have it activated in order to issue an alarm depending on a signal from the door status monitoring device about the opening of the door, in particular if there is no authorization to enter the door. A door may be unlocked for at least a certain time window. If the door is opened during this time window, an acoustic alarm is issued. The acoustic alarm can be issued in the time window or only if there is no authorization to enter the door.

In order to be able to execute the functions, parameters can be stored in the control device. For this purpose, the control device has, in particular, a non-volatile memory. The parameters can be set by an operator via the parameterization program. Thus, the control device can be used to store parameters. Logical links relating to the functions of the control device can be stored in the control device.

The control device is connected in particular to the first bus system. The control device can thus be integrated in one of the triggering elements. The at least one further triggering element, which is connected to the first bus system, is preferably configured without the control device. In this case, the control device can control the display device, the display element, the display, the lighting means and/or the acoustic alarm transmitter of the triggering element that includes the control device. The at least one further triggering element can be prompted by the control device to activate the display device, the display element, the display, the lighting means and/or the acoustic alarm device of the at least one further triggering element.

Alternatively, the controller may be integrated into one of the door lock controllers. The at least one further door locking controller, which is connected to the first bus system, is preferably designed without the control device.

In a further alternative, the control device is integrated neither in one of the triggering elements that are connected to the first bus system, nor in one of the door locking controls that are connected to the first bus system. Rather, the control device with all triggering elements that connected to the first bus system, and connected to all door lock controls connected to the first bus system via the first bus system. As a result, the control device z. B. away from the door in a technical room. For example, the control device in this variant can include the DIN rail housing.

The control device may have knowledge of the status of the door locks connected to the first bus system and/or the status of the triggering elements connected to the first bus system. The control device can have knowledge of a communication taking place via the first bus system between the door locking controller and the triggering elements. In particular, the control device has knowledge of the status of all door locks that are connected to the first bus system and/or knowledge of the status of all triggering elements that are connected to the first bus system. The controller may be aware of communications between the door lock controllers and the triggering elements connected to the first bus system.

The control device connected to the first bus system can selectively notify the number of door lock controllers and/or the number of trigger elements. Selectively means that the function is not executed for all components that can be reached via the first bus system, but only for a selection or for a single component that can be reached via the first bus system. In particular, the control device can activate selectively or cause activation selectively. The control device can only control the display device and/or cause control (function q.) and/or control the display and/or cause control (function r.) for the triggering elements that are assigned to the same door locking control as the actuated triggering element.

It is conceivable that parameters and/or assignments for selective activation are stored in the control device. In particular, it is stored in the control device to which triggering element of the number of triggering elements which of the door locking controls belonging to the number of door locking controls is assigned. This assignment is stored in the control device for all door locking controls of the first bus system.

If a trigger element is actuated and the actuation of the locking mechanism of the at least one door lock assigned to the actuated trigger element is to be actuated with a time delay, the control device causes the time delay to be displayed visually only in all those trigger elements which are assigned to the door lock control assigned to the actuated trigger element. is the control device is integrated in one of the triggering elements concerned, the control device controls the display device for this purpose.

If a door locking controller detects a change in a locking state, the control device can cause the change in the locking state to be displayed visually on the at least one triggering element that is assigned to the detecting door locking controller. The triggers that are not associated with the detecting door lock control are not caused to do so.

If a triggering element is actuated, the control device preferably causes an alarm state to be displayed optically and/or acoustically only in those triggering elements which are assigned to the door locking control assigned to the actuated triggering element. If the control device is integrated in one of the relevant triggering elements, the control device controls the display and/or the acoustic alarm device for this purpose.

If a triggering element receives a fire alarm signal, the control device preferably causes an alarm state to be displayed visually and/or acoustically only in those triggering elements that are assigned to the door locking control system assigned to the triggering element receiving the fire alarm signal. If the control device is integrated in one of the relevant triggering elements, the control device controls the display and/or the acoustic alarm device for this purpose.

In addition, the control device can selectively trigger non-safety-related activations for unlocking or locking.

Thus, the control device can control the locking mechanism for unlocking after receiving a positive authentication signal or cause such a control (function h.). For this purpose, the control device can be connected or can be connected to an access control system. If the control device receives z. B. a positive authentication signal from an access control system, the control device causes only an unlocking of the door lock that is assigned to the access control system.

The control device can, for. B. control the locking mechanism for unlocking at a predetermined time or cause such a control (function i.). The unlocking at a predetermined time can be provided if z. B. the door should be unlocked in a time window per day. Is only stored for a door lock of the first bus system that unlock the door lock at a predetermined time is, the control device causes the unlocking at the specified time only for one door lock, the other door locks of the first bus system remain locked.

If there is no danger, i. H. If neither the triggering element was actuated nor is there a fire alarm signal, the control device can activate the locking mechanism for automatic relocking after a predetermined period of time has elapsed or cause such activation (function k.). If the operator has stored a predetermined period of time of a first length for a door locking of the first bus system and a predetermined period of time of a second length, which differs from the first length, has been stored for a further door locking of the first bus system, the control device initiates a automatic re-locking for the one door locking after the first length of the predetermined period of time and for the further door locking re-locking after the second length of the predetermined period of time.

Additionally or alternatively, it can be provided that the control device activates the locking mechanism for automatic relocking immediately after receiving a signal about a closed state of the door or initiates such an activation (function I.). If an automatic relocking immediately after the door is closed has been stored as permitted for a door lock and not for a further door lock, the control device only initiates an automatic relocking immediately after the door is closed for the first door lock.

It may be that exactly one control device is provided for the first bus system. If there are a number of bus systems which are connected to the second bus system and to which at least one door locking controller and a triggering element are connected, each of the number of bus systems can have exactly one control device.

The safety system can have at least one input device to enable the selective activation or to cause the selective activation. To this end, the components that are connected to the first bus system can preferably each include an input device.

For example, the input device can have switches, in particular DIP switches. The components that are connected to the first bus system are referred to as bus users.

It is conceivable that the bus subscribers of the first bus system each have a bus address that can be set manually on the input device. Bus subscribers with the same manual setting can be assigned to one another. It may be that the respective bus user modifies the setting in such a way that a different bus address is generated despite the same setting for several bus users. The bus address that can be set manually is intended in particular for non-safety-related functions. Each bus user can include the manually adjustable bus address as a second bus address in addition to the unchangeable bus address for the safety-related functions.

It is preferably provided that the control device is connected to a control center, in particular a central escape route control and/or security device, via a second bus system, with information on the number of door locking controls or the number of triggering elements being able to be transmitted via the control device to the control center.

The object is also achieved by a method for controlling and/or monitoring door locks for securing escape routes according to independent patent 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.

The method according to the invention provides that, as a result of an actuation of a triggering element, at least one locking mechanism is triggered by a door locking controller to which the locking mechanism is to be assigned, and a number of door locking controllers and a number of triggering elements are connected to one another via a common bus system and the number of door locking controls are 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 that is assigned to the actuated triggering element controls the respective locking mechanism for unlocking.

18a-d a schematic representation of a sequence of a function release 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 causes the direct or indirect recipient of the message to carry out the activation. The sender of the message initiates the activation. Initiating a triggering is thus understood to mean an indirect triggering. In particular, the message can correspond to a bus telegram.

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

In the Figures 1 to 3 , 7 and 9 one safety system is shown in each case. Although only one emergency button 10 and one door lock 200 are shown in the figures, the principles presented there, in particular with regard to the design and function of the emergency button 10, the control device 100 and the central escape route control 300, also apply to the security systems according to the invention with several emergency buttons 10, 10', 1010, 1010', 2010, 3010 and several door locks 200, 200', 1200, 1200', 2200, 3200 as in the Figures 4 to 6 and 10 shown. An audio and video module 510 can also be integrated into the security systems 1 according to the invention.

In the figures 1 and 2 a first exemplary embodiment of a security system 1 for a door 2 is shown. The door 2 is not part of the security system 1. The security system 1 includes a door lock 200 and an emergency button 10. The emergency button 10 includes a control device 100. The emergency button 10 is assigned a key switch 500. 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, 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 the length of the positive one measure 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, i. H. if a fire alarm signal has been received or the emergency button 10 has been 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 lighting means 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, 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.

The electronics unit 24 also serves as a control device 100. Here, the first emergency button processing unit 20 serves as the first processing unit 103 of the 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 the door lock 200 to be unlocked independently of one another after the actuation signal has been detected via the first bus system 400. 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, ie as a result of pressing 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 may contain notification of being operated or an unlock control command. 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 second emergency button processing units 20, 21 then initiate a message to the first and second Processing means 202, 203 that the locking mechanism 205 is controlled by the door lock controller 201 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 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 purpose and to check the first and the second emergency button processing unit 20, 21, a sign-of-life signal from the first and the second emergency button processing unit 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 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 latch 200 to lock when the value of the first variable equals the initial value and prevents the door latch 200 from locking 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 operator must keep the key turned 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 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, an overriding 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 controller 201 controls the lock 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 second emergency button processing units 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 shows 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 to the door status monitoring device 204, 206 or connectable and receives signals about an open or closed status of the door from the door status monitors 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 receipt of 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 the door lock 200 includes the door status monitoring devices 204, 206. As an alternative to this 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 an embodiment of a security system 1 according to the invention with several 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. In each case, a door lock 200, 1200 is to be arranged on a door leaf 3, 4 of 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 otherwise described below, 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, alarms, lamps, switches and actuators.

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. Through the assignment, the assignment of the emergency buttons 10, 1010, 2010, 3010 to the door locks 200, 1200, 2200, 3200 deposited. 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 can communicate selectively with the door locks 200, 1200, 2200, 3200. It is stored in the control device 100 which door lock 200, 1200, 2200, 3200 is assigned to which access control system, so that in the event of a positive authentication signal from an access control system, only the assigned door lock(s) 200, 1200, 2200, 3200 are unlocked. Also stored in the control device 100 is whether and when, yes, which door lock 200, 1200, 2200, 3200 is to be unlocked at which predetermined time. It can also be stored in the control device 100 after which predetermined period of time or which predetermined periods of time which door lock 200, 1200, 2200, 3200 again should be locked. Also stored in the control device 100 is whether and, if so, which door locks 200, 1200, 2200, 3200 are to be locked again immediately after the door 2, 2002, 3002 is closed. It can be stored in the control device 100 whether, and if so, for which door lock 200, 1200, 2200, 3200 an acoustic alarm should be triggered when the unlocked door 2, 2002, 3002 is opened without a positive authentication signal being present. It can be stored in the control device 100 whether an acoustic alarm should be triggered if the door 2, 2002, 2003 is not closed again. The deposits can be made differently for each door lock 200, 1200, 2200, 3200 or for the groups of door locks 200, 1200, 2200, 3200 to be arranged on a door 2, 2002, 3002. The storage is done with the help of the parameterization program by the operator during commissioning.

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

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

The control device 100 can use the non-safety-related assignment for selective communication, e.g. B. assign an access control system to a door lock 200, 1200, 2200, 3200 based on a bus address. In this case, the participants of the first bus system 400 each have a setting device for manually setting a bus address. The setting device can include DIP switches. At least the users of the first bus system 400 that have the same setting on the setting device are automatically assigned to one another. In order to be able to assign different bus addresses to participants with the same setting, participants of the first Bus systems 400 different codes, from which different bus addresses are configured with the help of 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. Permissibility as to whether locking should take place after the predetermined time interval has elapsed with door 2, 2002, 3002 remaining closed can be set 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, can be individually adjusted 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 a security system 1 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 accommodates a central emergency button 302 and an identification device 312 designed as a key switch, for example. 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. The multi-door display device 350 can also be arranged in the escape route control housing 340, if present.

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 and the second fastening plate 321 for the deactivation module are used for fastening to the escape route control housing 340 320 and/or the third mounting plate 331 for the delay module 330. The escape route control housing 340 and the modules 310, 320, 330 are designed such that different sequences in which the modules 310, 320, 330 can be arranged side by side 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 . 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 a microprocessor or microcontroller. 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 signal about the opening of the first circuit 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 . If the 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. The central emergency button communicates here 302 via the control device 100 with the door locking control 201, in particular the first and the second processing means 202, 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 the door lock 200 is switched to the unlocked state as a result of the actuation of the central emergency button 302, the electronic device 207 prevents the door lock 200 from being able to be switched back to the locked state without the existence of a cancellation condition. 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 has remained permanently closed after the emergency button 10 has been actuated, the cancellation condition can be achieved by the elapse of a predetermined time interval and cancellation treatment at the central escape route control 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. A verification of the permissibility, an elapse of the predetermined time interval, an actuation of the key switch 312 after the predetermined time interval and the fact that during the predetermined time interval neither the first door status monitoring device 204 nor the second door status monitoring device 206 sent a signal about the opening of the door , are sufficient to meet the override condition.

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

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

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

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

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

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

The first delay period is displayed visually at the central escape route controller 300 . For this purpose, the central emergency button 302 is constructed according to the emergency button 10, as is the case 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 sends a message regarding the actuation of the termination element 333 via the second bus system 401. This prompts the emergency electronics unit 308 the emergency button 10 not to delay the unlocking any further, but to prompt unlocking of the door lock 200 immediately. 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 of the second operating element 323 is sufficient 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. perceive via the audio and video module 510. 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 with the audio and video module 510 via the second bus system 401 and, if necessary, via the first bus system 400.

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, 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, 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 only deactivates if the third variable has the first value Has.

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 latches 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 the unlocking from the actuation of the delay element 332 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, the 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 immediately unlocks the door lock after the first delay period 200 cause. 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 in each case to the emergency buttons 10, 1010, 1010', 2010' of the respective first bus system 400, 400', which do not include the control device 100. 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' can be stored with the aid of the parameterization program, as a result of an actuation of which of the first operating elements 322, 322' a deactivation is permitted. 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 embodiment of the security system 1 has 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 63.11, 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 transmitted through the hollow interior 38 to the crest 32 of the front surface 19 of the Actuating element 11 passed where the light passes through the actuating element 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 an initial position 13.1 into an actuated position 13.11. 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 attached to the mounting plate 62 by the same screws 72 that attach the mounting plate 62 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. For this serves the restoring means 12. 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 operating 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 green light and the locked state indicated by 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 already unlocked is. 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 conduct light up to a section 45 of the light guide region 44 that spreads out.

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 luminous areas 50b, 50c, 50f and 50g by the 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 the Actuating element 11 covers at least one of the opposing luminous areas 50 .

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 indicated after the door lock controller 201 communicates the status change to the control device 100 . 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 available is shown. 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 in the description of at least one of 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 ). through the Arrangement in the receptacle 77, the communication module 801 is mechanically held 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, the control device 100, after reading out the code of the communication module 801, initiates an 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 performed by the emergency button 10, which is connected to the control device 100 via the first bus system 400, then the control device 100 causes the function to be blocked via the first bus system 400. If the function is performed by the door lock controller 201, which communicates with the control device 100 via the first bus system 400 is connected, the control device 100 initiates a blocking of the function 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 are read out 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.
