CHQ-DZM(SCI)-IS/SIL
- SIL Level 2 approved
- Ideal for use in oil and gas environments
- Single loop address
- Supports two independent zones of conventional detectors
- Both zones fully monitored for short/open circuit
- Requires an auxiliary 24 VDC supply
- Both models feature an integral short circuit isolator
- Approved by LPCB
Model CHQ-DZM(SCI)-IS/SIL 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 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)-IS/SIL at all times.
The CHQ-DZM(SCI)-IS/SIL utilises simple DIL switches for reliable addressing.
When Resistive EOL option is chosen the conventional zone on the CHQ-DZM(SCI)-IS/SIL does not support any line continuity options, therefore if Call Points are being interfaced they should be wired at the beginning of the zone.
