Model ST-ZM1B-SC 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; both models feature an integral short-circuit isolator. The ST-ZM1B-SCutilises simple DIL switches for reliable addressing. A back box is also available (ST-MBB) which, when used in conjunction with the ST-ZM1B-SC increases the IP rating to IP65. The conventional zone on the ST-ZM1B-SC does not support any line continuity options; if Call Points are being interfaced they should be wired at the beginning of the zone.
