The unit 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.

Features

• Supports two independent zones of conventional detectors
• Both zones fully monitored for short/open circuit
• Requires an auxiliary 24 V dc supply
• DIN rail version available
• Both models feature an integral short-circuit isolator
• Approved by LPCB
