DN-6936:B•H-211 FST-851 (A) Series NOTIFIER Intelligent Thermal (Heat) Detectors 9 with FlashScan® by Honeywell Intelligent /Addressable Devices General Notifier FST-851(A)Series intelligent plug-in thermal detectors with integral communication has features that surpass conven- tional detectors. Point ID capability allows each detector's address to be set with rotary, decimal address switches, pro- 4 viding exact detector locations. FST-851(A) Series thermal detectors use an innovative thermistor sensing circuit to pro- > duce 135°F/57°C fixed-temperature (FST-851/A) and rate-of- rise thermal detection (FST-851R/A) in a low-profile package. t FST-851H(A) provides fixed high-temperature detection at 190°F/88°C. These thermal detectors provide effective, intelli- gent property protection in a variety of applications. FST- 851(A)Series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels(FACPs).
