Analogue Single Zone Module CHQ-SZM(HFP)-SCI
Description
Analogue Single Zone Module CHQ-SZM(HFP)-SCI is a Single Zone Monitor designed to allow up to 6 conventional detectors to be interfaced to Hochiki’s ESP analogue addressable system. The unit is also available as a DIN Rail mountable version; with or without an integral short-circuit isolator. The unit utilises simple DIL switches for reliable addressing. A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-SZM(HFP)-SCI, increases the IP rating to IP65. The conventional zone on the CHQ-SZM(HFP)-SCI does not support any line continuity options; if Call Points are being interfaced they should be wired at the beginning of the zone.
