Addressable Intelligent Rate of Rise / Fixed Temperature Heat Detector


NOTIFIER FST-851 Series intelligent plug-in heat detectors with integral communication has features that surpass conventional detectors. Point ID capability allows each detector’s address to be set with rotary, decimal address switches, providing exact detector locations. FST-851 Series heat detectors use an innovative thermistor sensing circuit to produce 135°F/57°C fixed-temperature (FST-851/A) and rate of rise thermal detection (FST-851R/A) in a low-profile package. FST-851H(A) provides fixed high-temperature detection at 190°F/88°C. These thermal detectors provide effective, intelligent property protection in a variety of applications. FST- 851 Series detectors are compatible with Notifier Onyx.
