Heat Detectors

CR Series Heat Detector

CR Series standard heat detectors are combination rate-of-rise and fixed-temperature detectors.

CR Series heat detectors are combination rate-of-rise and fixed-temperature. The rate-of-rise function allows the detectors to operate when the temperature at the detector increases at a rate of 15 °F per minute. The fixed-temperature portion will cause the detector to operate when it reaches the applicable temperature. The rate-of-rise portion of the detector is restorable; however the fixed-temperature portion is non-restorable.
