Vigilant Heat Detector Type C Green Dot (614TC)- 4098-9639EA The Type C Green Dot detector is High temperature duty, incorporating both fixed-temperature (88 ºC - 132 ºC) and a rate-of-rise actuation. Tyco 614TC heat detectors use a fast response,thermistor based design. The fixed temperature sensing thermistor readily tracks the local ambient temperature, thus quickly, accurately and consistently identifying when a fixed temperature is exceeded. Rate-of-rise detection is achieved by comparing the response of two thermistors, with one having a slower thermal response. By combining accurate thermistors with proper physical placement, this patented rate-of-rise detection design achieves a high level of heat detection performance.
