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
