Conventional Heat Detector

Heat Detector

The C9021T Conventional Heat Detector continuously monitors ambient temperature and activates when the preset threshold is reached. It is particularly suitable for locations where smoke detectors may not perform effectively. It is not recommended where smoldering fires or heavy smoke are expected before a significant temperature increase.
