Notifier FST-851(A) Series intelligent plug-in thermal 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(A) Series thermal 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(A) Series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs).

  • Sleek, low-profile, stylish design.
  • State-of-the-art thermistor technology for fast response.
  • Rate-of-rise model (FST-851R/A), 15°F (8.3°C) per minute.
  • Factory preset fixed temperature at 135°F (57°C); high-temperature model fixed at 190°F (88°C).
  • Addressable by device.
  • Compatible with FlashScan and CLIP protocol systems.
  • Rotary, decimal addressing (1-99 on CLIP systems, 1-159 on FlashScan systems).
  • Two-wire SLC connection.
  • Visible LEDs “blink” every time the unit is addressed.
  • 360°-field viewing angle of the visual alarm indicators (two bi-color LEDs). LEDs blink green in Normal condition and turn on steady red in Alarm.
  • Integral communications and built-in device-type identification.
  • Remote test feature from the panel.
  • Built-in functional test switch activated by external magnet.
  • Walk test with address display (an address of 121 will blink the detector LED 12-(pause)-1).
  • Low standby current.
  • Backward-compatible.
  • Built-in tamper-resistant feature.
  • Designed for direct-surface or electrical-box mounting.
  • Sealed against back pressure.
  • Plugs into separate base for ease of installation and maintenance. Separate base allows interchange of photoelectric, ionization and thermal sensors.
  • SEMS screws for wiring of the separate base.
  • Constructed of off-white fire-resistant plastic, designed to commercial standards, and offers an attractive appearance.
  • 94-5V plastic flammability rating.
  • Remote LED output connection to optional RA100Z(A) remote LED annunciator.
  • Optional sounder, relay, and isolator bases.
  • Optional flanced surface mounting kit.
