Notifier FST-851R SF 23/10 indicated the relay coil isNotifier FST 851(A) Series intelligent plug in thermal detectors with integral communication has features that surpass conventional detectors. Point ID capability allows each detectors address to be set with rotary, decimal address switches, providing exact detector locations. FST 851(A) Series thermal detectors use an innovative thermistor sensing circuit to produce 135F 57C fixed temperature (FST 851 A) and rate of rise thermal detection (FST 851R
