GFS - Door guard with radio transmitter for discos

Especially in this area it is known that terrible disasters occur all over the world due to locked emergency exits.
The GFS radio door guard is an extension/addition of the GFS door guard which has been on the market for more than 10 years.

How it works
When the radio door guard is locked in its upright position it secures the door handle or latch. With an easy 45 degree push, the door handle or latch is now ready to be pressed or moved. At the same time a siren goes off. This means: The door can be opened in an emergency situation. On the other hand it also brings misuse to the attention. The integrated board transmits the signal (alarm) to the receiver. An earpiercing sound emits from the door guard as well as from the receiver. Only an authorised person who is in possession of the key can switch the alarm off by turning the key. Thus bringing the radio door guard back into its upright position.

GFS chose a well designed alarm receiver: Combining a loud siren (120 dB/1 m) with a flashing light. The unit is equipped with a 1.5 m (230 V) mains cable and a plug. All that is required is a wall socket close by. The radio door guard is battery operated.
