Hochiki CHQ-DSC2(HFP)-SCI Analog Addressable Dual Siren Control Module with Short Circuit Isolator

CHQ-DSC2 is an addressable siren control module providing two separate audio outputs with fault supervision. Because the outputs can be operated independently, warning devices in two different zones are managed separately; a zoned evacuation scenario is thus established. It enables conventional sirens to be incorporated into the addressable system scenario. Line breaks and short circuits are continuously monitored.
