Hochiki CHQ-DZM(SCI)-IS Intrinsically Safe Compatible Dual Zone Monitor with SCI
Product Details for Hochiki CHQ-DZM(SCI)-IS Intrinsically Safe Compatible Dual Zone Monitor with SCI
The Hochiki CHQ-DZM(SCI)-IS is Dual Zone Module which is fully compatible with Hochiki's ESP analogue addressable protocol and I.S. equipment. It is supplied as an OEM version (as illustrated) which can be fitted within an IP67 rated enclosure. The unit is also available as a DIN Rail mountable module; both models feature an integral short-circuit isolator. 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.
An appropriate barrier must be used.
