Designed for spaces where normal ambient temperatures run too high for a standard heat detector, the Notifier FST-951H is a low-profile intelligent thermal sensor factory preset to a 190°F fixed alarm point. It belongs to Notifier's FST-951 Series, the direct replacement for the FST-851 Series, and communicates on FlashScan signaling line circuits only.
Key Features
- Fixed-temperature alarm point of 190°F (88°C), factory preset
- Thermistor technology for fast response with built-in device-type identification
- Rotary decimal switches set the point address for exact location reporting
- Two LEDs with 360° visibility: blink red when polled, steady red in alarm
- Built-in tamper-resistant feature and magnet-activated functional test switch
- Plugs into a separate base, allowing interchange with photoelectric and ionization sensors
