Hochiki Marine Approved Single Zone Monitor CHQ-SZM/M(SCI)
The unit features an integral short-circuit isolator and utilises simple DIL switches for reliable addressing.
A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-SZM/M(SCI), increases the IP rating to IP65.
The conventional zone on the CHQ-SZM/M(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.
