After the subsequent Verklipsen the housing bottom 111 with the middle part 113, the light bar 114 is held securely. The light bar 114 is illuminated by LEDs (light emitting diodes) which are arranged on a circuit board in the housing 11. There are multicolored LEDs arranged on the board, which are controlled by the control device 14 to realize a multi-colored status display.

The locking connection between the cover 112 and the middle part 113 is detachable by inserting a special tool, not shown in through holes 114 d, in the longitudinal sides of Luminaire strip 114 are arranged (see Fig. 8 ). Thus, the cover frame 112 can be easily replaced or replaced.

In the in the Fig. 1 to 9 illustrated embodiment, the housing bottom 111 is formed as a flush-mounted housing floor with a flushing insert 116, which is insertable into a flush-mounted box 29. For mounting the housing 11, an adapter plate 115 is provided, which is connectable via fastening means with the flush-mounted box 29 and has receptacles 115a for fastening the housing 11 (see Fig. 9 ). As fastening means may preferably be provided fastening screws with a circular cross-section screw head, which pass through in the adapter plate 115 arcuate mounting slots 115 s and screwed into threaded holes, which are formed in the flush-mounted box 29. The fastening slots 115s each have an end section designed as a through hole, the inner diameter of which is greater than the outer diameter of the screw head of the fastening screw. The adapter plate 115 has a central opening 115 o, through which the flushing insert 116 of the housing 11 (see Fig. 1 ) and into the flush box 29 engages.

The adapter plate 115 is formed so that it is also connectable to a cavity box.

Next, the adapter plate 115 through holes 115d for mounting the adapter plate 115 on a wall, the emergency button 1 in this case has a surface of the housing.

In the housing 11, a sabotage switch is arranged, which detects a lifting or removing the housing 11 of the adapter plate 115. The tamper switch is connected to the controller 14 so that it can generate a tamper alarm.

In the housing 11, a display 13 is arranged, which is mounted with further modules on a chassis 117 (see Fig. 3 ). The chassis 117 is formed together with the display 13 as a replaceable unit and slidably mounted in the housing 11.

The chassis 117 is urged by springs 117f in a neutral position in which it rests against the inside of the housing 11. The chassis has stops 117 on which rest in the neutral position on the inside of the housing 11.

The function of the emergency button is realized by pushing the front of the display 13, the chassis 117 and thus the display 13 against the force of the springs 117f in the housing 11 is pushed into it. At the end of the travel, an electrical switch contact 12 is actuated to release a latch and / or generate an alarm, similar to a conventional emergency button.

The shift takes place against the force of springs to achieve an ergonomic operation. The springs 117f formed as leaf springs are arranged on the rear wall of the chassis 117. The springs 117f may alternatively be designed as helical compression springs, as in FIG Fig. 8 shown. It is also possible to use leaf springs and coil springs side by side in a housing.

The chassis 117 is guided in brackets 117 b, which are arranged on the rear wall of the chassis 117 and supported on the inner wall of the housing bottom 111 in parallel in the housing 11. The chassis 117 is therefore without tilting into the housing 11 can be inserted (see 3 and 4 ). The brackets 117b are formed as double U-shaped brackets which are pivotally supported at their end portions and whose connecting portion slides over the inner wall of the housing bottom 111 when the chassis 117 is displaced. The display 13 is formed by inlet bevels 112s formed on the cover frame 112 (see FIG Fig. 2 ) centered in the cover frame, wherein the leading edges of the chassis 117 cooperate with the inlet slopes 112s.

On the chassis 117, a control device 14 is arranged. This includes a graphics board 117g for driving the display 13 and a control board 117s. On the control board 117s electrical interfaces 117p are arranged with connectors which serve as ports for the signal transmission between the control board 171s and the graphics board 117g and between the control board 171s and sensors and / or switches and / or actuators. In addition, the control device 14 has a digital interface for connection to a digital bus. Via the bus, the control device 14 with other escape route security devices and / or with central control or access control systems connected. The display 13 is designed as a touch-sensitive display or touchscreen on which, for example, a stylized emergency key and / or a keypad for entering an access authorization code can be displayed or is, as described in more detail below.

Further, the controller 14 includes an optical display module having multicolor LEDs disposed on the control board 117s. These illuminate the light bar 114 and are controlled by the control device 14 in order to realize a status display and / or an alarm display. For example, the light bar is illuminated green when the door is released and red when the door is locked.

In the FIG. 10 the escape route safety device is shown in a schematic representation. This emergency exit device has two escape routes. There is a door in every escape route. Each door has a door leaf 21, which is rotatably mounted on bands on a door frame 22. At the upper end of the door acting between door frame and door locking device in the form of a magnet 23 is arranged. When energized, the magnet locks the door and prevents the door from opening. If the magnet 23 is deenergized, the door is accessible via a conventional door lock.

In the area of each escape route, the emergency button 1 is mounted on a wall. The emergency button 1 is arranged approximately at the height of the door lock in the region of the closing edge of a door leaf. The emergency button 1 each has a housing in which the control device 14 is received.

The emergency button or the control device is connected to the locking element 23 via an electrical connection line.

Via a digital CAN bus 4, the emergency buttons are connected to each other and to an access control system 3. To the bus 4 also a time generator 31 is also connected, which feeds a time signal on the bus 4.

In the following, individual functions of the control device 14 will be described in more detail.

The control device 14 can be switched from an alarm mode to an operating mode. In the alarm mode, the control device 14 displays on the touch-sensitive display 13 a stylized emergency button and a control bar or a control knob. When touching the control bar or the control knob no alarm is generated, but the controller 14 is switched to the operating mode.

In the area of the light bar 114 or of the optical display module, an RFID receiving device is arranged and connected to the control device 14. RFID transponders (RFID tags) can be read out via the RFID receiving device and the control device 14 can be controlled. Thus, the controller 14 is switchable by a valid RFID tag in an operating mode or in a programming mode or in an access control mode.

As in FIG. 2 is shown, a connection board 117a is disposed in the housing 11 in the region of the flush-mounting box. This terminal board has terminals to electrically contact the controller 14 and the escape route safety device, respectively. The display 13 or the chassis 117 is connected via a movably guided ribbon cable 118 to the connection board 117 a.

The control device 14 generates in the alarm mode when touching the display 13 outside the range of the control bar or the control knob one Pre-alarm and after a certain period of time, if the contact persists, generates a main alarm and controls the locking element to unlock the door. The time span is adjustable.

The pre-alarm can also be provided as a selective pre-alarm in that only one touch of the display 13 in the area of the emergency button displayed by the control device 14 on the display 13 triggers a pre-alarm. After the adjustable period of time, if the touch persists, the control device 14 triggers a main alarm. In parallel with the triggering of the main alarm, the control device 14 controls a locking element for unlocking the door.

When moving the display 13 by pressure on the front side of the display 13, an electrical switching contact 12 is actuated, which is arranged on the control board 117 s. The control device 14 generates a main alarm in the alarm mode when operating the electrical switch contact 12 and controls the locking element to unlock the door.

The triggering of the main alarm can take place optionally via the actuation of the electrical switching contact 12 or via the pre-alarm and continuous contact of the display 13.

The control device 14 is programmable and / or configurable in an operating mode. As part of a programming or configuration of the control device 14 parameters can be entered or changed via an operating program displayed on the display 301 or individual functions of the control device 14 can be activated or deactivated.

For example, it can be set via parameters that the pre-alarm is switched as a selective pre-alarm, or the time until the main alarm is triggered can be set or adjusted.

The operating mode of the control device 14 is designed as an access control mode and the control device 14 displays in the access control mode on the display 13 a keypad for entering an access authorization code. Upon entry of an authorized access authorization code, the controller 14 controls a locking element to unlock the door without triggering an alarm.

The controller 14 has a rewritable log memory to store events. To do so, the controller 14 provides events, such as an alarm message or door opening, or entry of an access authorization code with time information and stores this associated data in the log memory.

The control device 14 has an operating time counter, wherein the control device 14 triggers the operating time counter when switching from the alarm mode to the operating mode. The operating time counter switches back to the control mode 14 from the operating mode in the alarm mode after a certain, in particular preselectable period of time.

In the operating mode, the control device 14 triggers the operating time counter during an input or resets the operating time counter.

The control device 14 has an alarm timer and a door sensor for monitoring an opening of the door, wherein the control device 14 in Alarm mode when generating the main alarm and / or release of the locking device triggers the alarm timer and this controls the controller 14 after a certain, in particular presettable alarm period for resetting the main alarm and locking the locking device, if no opening of the door has occurred during the alarm period.

The control device 14 switches permanently in an alarm-open mode if an opening of the door has taken place within the alarm period.

The control device 14 displays a permanent alarm opening signal in the alarm-open mode on the display 13 and / or an optical status display. As optical status indicator is in the in Fig. 1 to 9 illustrated embodiment, the light bar 114 is provided.

The control device is designed so that it can be switched back into the alarm mode or into a basic mode only after code input or actuation of a key switch from the alarm-open mode. The alarm-open mode thus simulates the known mechanical locking of the emergency button by a conventional bus terminal.

In the alarm mode, the control device 14 displays after the triggering of a pre-alarm on the display 13, the remaining time remaining until the triggering of the main alarm. This is done by, for example, the control device 14 displays a decreasing synchronously with the remaining time bar or a decreasing circle on the display 13. It can also be displayed directly the remaining time in seconds.

The controller 14 releases the locking device delayed in the alarm mode and displays on the display the remaining time until the release of the locking device.

The control device 14 has a bus interface via which it can be connected to a digital bus. The control device can send and / or receive status messages and / or alarm messages via the digital bus. In addition, the control device 14 can control a locking device and / or an optical and / or acoustic alarm transmitter via the digital bus.
The controller 14 receives a time signal via the digital bus. This is evaluated by the control device 14 and linked with status messages or alarm messages by the controller 14 messages and / or events with a time signal obtained from the time signal connects and sends them as a connected date via the bus interface and / or stores in a local memory ,

In order to bridge the times in which no time signal can be received via the digital bus, the control device 14 has a time counter. This time counter is synchronized at short intervals with the time signal received via the bus interface. Thus it can be dispensed with its own emergency power supply by batteries or capacitors.

The control device 14 is switchable into an access control mode and connects messages and / or events occurring in the access control mode with a time stamp and sends them via the bus interface and / or stores them in a local access control memory.

Connected to the bus is a control unit which generates the time signal and sends it to the bus via the bus interface.

The control center is connected to the Internet and generates the time signal, for example, based on a time server available on the Internet.

If there is no connection to the Internet, a time signal generator is connected to the bus. The time signal generator has a clock module and generates the time signal based on the time supplied by the clock module. The time signal generator then sends the time signal to the bus via a bus interface.

The time signal generator has its own emergency power supply. The emergency power supply can have, for example, a rechargeable accumulator and / or a capacitor.

Several emergency buttons, each with its own control device, can be connected to the bus and these multiple control devices can be synchronized with one another by the time signal.

It is also contemplated that multiple emergency buttons will synchronize with each other through an event, such as an alarm, a main alarm, or a sabotage alarm.

The time generator can be integrated into an emergency button, in particular integrated in a housing of an emergency button.
