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.
