Hochiki Intrinsically Safe Sounder Module (CHQ-ISM)

Hochiki CHQ-ISM Intrinsically Safe Sounder Module

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.

Key Features:

• Provides dual sounder circuits
• Provides fault-monitored input
• Interfaces between loop and I.S. sounders/beacons
• Fully monitored for short-circuits
• Requires 24 vdc external power supply
• Also available as a DIN module
