AL ATT

This device is suitable for resetting the sound level of loudspeakers equipped with an attenuator (local or remote) with a level reset relay.
This reset can be controlled by a microphone station (MAGPL) or by a “UGA for evacuation message”.
The level is reset by the presence or absence of the 24V/ For use with EN 54-16 products, the reset is carried out on failure. An automatic reset is then necessary due to the absence of electrical power.
