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
