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. CHQ-DZM(SCI) Features & Specifications - 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)
