It provides either a two-wire or four-wire fault-tolerant Initiating Device Circuit (IDC) for normally-open-contact fire alarm and supervisory devices

Two LEDs on each sensor light to provide 360°F visibility of the sensor indication

System Sensor 2351B-IV Intelligent Photoelectric Smoke Detector FSL-751A Intelligent devices communicate in aThe System Sensor 2351B (2351B IV) photoelectric detectors re designed optical sensing chamber is engineered to sense smoke produced by a wide range of combustion sources in accordance with more stringent code standards. The sensitivity of Select Series detectors can be programmed using the control panel software to suit the environment. The 2351BR (2351BR IV) photoelectric detector is also remote test capable for use with a DNR (DNRW) duct smoke
