CHQ-DZM(SCI) | Hochiki's EN Approved Fire Detection

CHQ-DZM(SCI) Description 

 

CHQ-DZM(SCI) is a Dual Circuit Zone Controller designed to allow up to 60 conventional detectors (30 on each zone) to be interfaced with 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, ensuring the integrity of the CHQ-DZM(SCI)
at all times. The CHQ-DZM(SCI) utilizes simple DIL switches for reliable
addressing.

 

When Zenner Diode 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.
