This device is appropriate for resetting the sound level on loudspeakers fitted with (local or off-set) an attenuator with level reset relay.
- This reset can be controlled by a microphone station (MAGPL) or by a “UGA” for the evacuation message.
- The level reset is made by occurrence or breakdown of the 24V. For any use with EN 54-16 products, reset is made with breakdown. An automatic reset is then necessary due to the absence of electrical power.
