The control unit is able to monitor transits through the emergency exits.
Authorised personnel can open the door without triggering the alarm by activating a no-voltage contact using a badge, keypad, keyswitch, etc..
If the door is closed again within a set time, no alarm is activated. If the door remains open longer than its “extended opening” time, the specific alarm is activated. This alarm deactivates automatically when the door is closed again or the reset button is pressed.
But if the door is opened without authorisation, the “Opening” alarm is activated immediately and remains active for the set alarm duration, after which an automatic auto-reset deactivates the alarm for 5 sec. If the door has been closed again, the system now returns to stand-by.
If the door is still open, the alarm status is reactivated.
The reset can also be performed by a remote button. |
