ST-I1B
This Sounder Control Module interfaces between the Hochiki Analogue system via a ST-SC2B-SC or conventional sounder outputs 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.
