The Tyco 631H-F (516.600.033) is a conventional Heat Detector with a 90 degree Celsius set point that used two networked thermistors in a bridge configuration to provide a fast response.
The Tyco 631H-F (516.600.033) is a conventional Heat Detector with a 90 degree Celsius set point that use's 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. Part Number 516.600.033
