    Hochiki ESP Dual Zone Monitor with SCI with DIN Rail Option

    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.
