Device for monitoring emergency exit doors and for opening them in an emergency

摘要

The monitoring of the opening of emergency exit doors in the event of an emergency is carried out in a central safeguarding system (8). In this process the handle (1) of the emergency exit door (4) is blocked by a device (2, 3) in normal operation. In the event of an emergency, the seal (5) is removed. The locking piece (2) is rotated until the stop (22) releases the end (11) of the pivotable door handle (1) to open the door (4). In this process, a bolt contact maker which is built into the casing (3) is actuated. This causes electrical signals to pass through the wiring (41) to the central safeguarding system (8). Recording, logging, storage, indication and the emission of an alarm are then carried out centrally for the alarm sequence, with documentation. <IMAGE>
