The WR-003B thermal detector is a program differential detector that compares the temperature difference when the ambient temperature rises above a certain temperature. When the fire temperature is exceeded, the LED of the detector lights up to indicate the fire.
Detectors incorporate a programmed sensor to detect the rate of temperature change, detect sudden changes in temperature between two sensors during a fire, and maintain a balance between the two thermistors during a gentle rise to prevent non-recurrence.
