The Hochiki CHQ-DZM(SCI) is a marine-approved dual circuit zone monitor designed to allow up to 60 conventional detectors (30 on each zone) to be interfaced to Hochiki's ESP analogue addressable system.
The unit features a Schottky Diode line continuity option, when used inconjunction 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.
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.
