614T Heat Detector

VIGILANT 614T 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.
