Hochiki Dual Zone Monitor with SCI

Model CHQ-DZM(SCI) is a Dual Circuit Zone Controller designed to allow up to 60 conventional detectors (30 on each zone) to be interfaced to Hochiki’s ESP analogue addressable system. The unit also features a Schottky Diode line continuity option, when used in conjunction with the optional LCMU.

Full monitoring against malfunction or disconnection, together with a self-test feature through the ESP protocol, ensure the integrity of the CHQ-DZM(SCI) at all times. The CHQ-DZM(SCI) utilises simple DIL switches for reliable addressing. It is available as an OEM version (as illustrated above) and also as a DIN Rail mountable module (CHQ-DZM/DIN(SCI)). Both models feature an integral short-circuit isolator.

Please note: When Resistive EOL option is chosen the conventional zone on the CHQ-DZM(SCI) does 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
● Supports two independent zones of conventional detectors
● Both zones fully monitored for short/open circuit
● Requires an auxiliary 24 V dc supply
● DIN rail version available
● Both models feature an integral short-circuit isolator
● Approved by LPCB
