Hochiki ESP Dual Zone Monitor with SCI With DIN Rail Option
£89.15 – £175.73
Summary
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 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.
