Description

CHQ-DZM/DIN(SCI) – Hochiki Dual Zone Monitor DIN Module with SCI

Model CHQ-DZM/DIN(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 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/DIN(SCI) at all times.  The unit utilises simple DIL switches for reliable addressing.  It is also available as a boxed module (CHQ-DZM(SCI)).  Both models feature an integral short-circuit isolator.

NOTE: When Resistive EOL option is chosen the conventional zone on the CHQ-DZM/DIN(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.

Key Features:

  • Single loop address
  • Supports two independent zones of conventional detectors
  • Both zones fully monitored for short/open circuit
  • Requires an auxiliary 24 V dc supply
  • Also available as a boxed module
  • Both models feature an integral short-circuit isolator
  • Approved by LPCB
