Hochiki ESP Dual Zone Monitor c/w Isolator

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 resistive mode in conjunction with the
optional LCMU.

Full monitoring against malfunction or disconnection, together with a self-test feature through the ESP protocol, ensuring the integrity of the CHQ-DZM(SCI)
at all times. The CHQ-DZM(SCI) utilises simple DIL switches for reliable addressing.

When Zenner Diode EOL option is chosen the conventional zone on the CHQDZM(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.
