This Sounder Control Module interfaces between the Hochiki Analogue system via a CHQ-DSC or conventional sounder O/P’s and the intrinsically safe sounder/beacon units via an intrinsically safe barrier.
The module provides line monitoring for open or short circuits on the wiring connected to both the safe and hazardous areas.
Provides dual sounder circuits
Provides fault-monitored input
Interfaces between loop and I.S. sounders/beacons
Fully monitored for short-circuits
Requires 24 V dc external power supply
