Tyco 631H-F 90°C Fixed Temperature Heat Detector

Tyco 631H-F is a 90°C Fixed Heat Detector that used two networked thermistors in a bridge configuration to provide a fast response. This depends on both 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.
