Hochiki Intrinsically Safe Dual Zone Monitor DIN Module with SCI (CHQ-DZM/DIN(SCI)-IS)

Hochiki CHQ-DZM/DIN(SCI)-IS Intrinsically Safe Dual Zone Monitor DIN Module 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.
