GFS EH-TÜRWÄCHTER
The barrier under the door handle is active. In an emergency, the door can be opened with one handle.
When the door handle is pressed, the Exit Control 179/1125 automatically shifts downwards. Passing through the emergency exit door is now possible. A continuous alarm sounds, which can only be deactivated by an authorized person using the device key.
With the device key, the door guard can be moved downwards into a permanent release position without triggering an alarm. In this position, the door can be used normally, e.g., for extended goods transport.
As soon as the door handle suppresses the pre-alarm, an alarm is triggered. The alarm ceases when the handle is released. However, if the user pushes the handle down completely, it irrevocably triggers the main alarm and the door guard releases the handle.
