The heat detector is intended for detecting fires in their early phase. The detector has a thermistor heat detection system. The application of such type of a sensor allows to detect fires quick and with certainty. Additionally, the detector has the flashing visual signalling device built-in due to which the detector fire alarm is visible from a large distance. The detector operates within the AWEX fire alarm system. The element can be installed on the detection loops or stub detection circuits.
The heat detection takes place by means of 4-thermistor temperature measurement system. A fire alarm is generated when temperature limit is achieved, or in case of quick increase of temperature. Then, it recognises the type of alarm and transmits it to the supervisory line, and to the control unit.
