The unit is also available as a DIN Rail mountable version; both models feature an integral short-circuit isolator. The CHQ-SZM2(SCI) utilises simple DIL switches for reliable addressing. A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-SZM2(SCI), increases the IP rating to IP65. The conventional zone on the CHQ-SZM2(SCI) does not support any line continuity options; if Call Points are being interfaced they should be wired at the beginning of the zone.
