Model CHQ-DZM(SCI)-IS is Dual Zone Module which is fully compatible with Hochiki’s ESP analogue addressable protocol and I.S. equipment. The unit is also available as a DIN Rail mountable module. Addressing is achieved via simple DIL switches.
The device is designed to allow up to 40 (20 per zone) Conventional I.S. CDX Range detectors (SLR-E-IS or DCD-1E-IS) in the hazardous area to be interfaced to Hochiki’s ESP analogue addressable system within the safe area*. (Please note that this module should only be installed in the safe area).
The conventional zones on the CHQ-DZM(SCI)-IS do not support any line continuity options; therefore if Call Points are being interfaced they should be wired at the beginning of the zone.
