Tyco 631HF 90ºC (516.600.033) Fixed Heat Detector

The Tyco 631HF (516.600.033) is a Heat Detector that used two networked thermistors in a bridge configuration to provide a fast response. This depends  both on absolute temperature and notes the change in the temperature. The Rate of rise/fixed temperature detectors can be used in areas where smoke sensors are unsuitable due to environmental conditions such as smoke and dust.

The 631HF can be used with:
4B 517.050.041 4" Detector Base
5B 517.050.017 5" Detector Base
4B-I 517.050.043 Isolator 4" Detector Base
