Hochiki Intrinsically Safe Compatible Dual Zone Monitor - DIN Enclosure with SCI

Model CHQ-DZM/DIN(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 a DIN Rail mountable module, a boxed version is also available. 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.

The conventional zones on the CHQ-DZM/DIN(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.

Key Features:

● Single loop address
● Requires an auxiliary 24 V dc supply
● Supports two independent zones of Hochiki I.S. Conventional Detectors
● Both zones fully monitored for short/open-circuit
● Boxed module version also available
● Both models feature an integral short-circuit isolator
Please note: that this module should only be installed in the safe area.
