Overall, the Bosch FAH-440 is a analog heat detector with Rate of Rise capabilities. Also, the Bosch FAH-440 Analog Heat Detector is an open-area fire detector that works with the FPA‑1000 fire panels. Use it with the FAA‑440 family of bases in indoor dry environments with high ambient temperatures. Use it in kitchens, boiler rooms, or drying rooms unsuitable for smoke detectors because of steam or fumes. Also, the detector has a valid address range from 1 to 254. The address is set by rotary switches on the back of the detector.
The detector head has a multi‑color LED to indicate status. To verify detector power and analog addressable loop communication, the LED indicator flashes green when operating normally (polling). Through panel parameter setting, it is possible to turn on or off the operation of the polling indicator. In the event of an alarm condition, the detector LED always shows a steady red light. Besides, independent from the actual number of activated device LEDs and remote indicator LEDs, the number of activated LEDs is limited to five (called the rolling alarm function).
Furthermore, the detector is part of a two‑piece modular design for detector assemblies. A detector attaches to a base in the FAA‑440 Analog Standard Base or Analog Isolator Base family. The base’s security locking tab prevents any unauthorized detector removal from the base.
