How do Promtex membrane beacons work?
One of the most important parts of the anti-masking device is the membrane, which is located in the front part of the device. There is also a microswitch mounted near it. In case of a mechanical impact on the membrane, the microswitch is immediately activated. On the other hand, there is a list at the back of the beacon, through which the power supply can be connected. The main task of the hole in the housing is to compress excess pressure that may occur inside the sounder.
