Apollo, 55000-127APO, BR Heat Detector

Apollo, 55000-127APO, BR Heat Detector

The heat detector operates by using a matched pair of thermistors to sense heat. One thermistor is exposed to the ambient temperature, the other is sealed. In normal conditions, the two thermistors register similar temperatures, but, on the development of a fire, the temperature recorded by the exposed thermistor will increase rapidly, resulting in an imbalance of the thermistors and causing the detector to change to the alarm state.

BR is Rate of Rise detector, designed to detect a fire as the temperature increases, but it also have a fixed upper limit at which the detector will go into alarm if the rate of temperature increase has been too slow to trigger the detector earlier.

Key Features:

• Ideal for environments that are dirty or smokey under normal circumstances
• Can be used for applications where smoke detectors are unsuitable
• Wide operating voltage
