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. Single loop address Supports two independent zones of conventional detectors Both zones fully monitored for short/open circuit Requires an auxiliary 24V dc supply Approved by LPCB Ordering code: CHQ-DZM(SCI) - SCI Module | CHQ-DZM/DIN(SCI) - DIN Module with SCI Operating voltage: 17 – 41 VDC Low power mode (typ): 110 ?A Quiescent current (typ): 330 ?A Current consumption (external): (Quiescent) 2 mA, (Alarm) 70 mA (Both zones in fire)
