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 signaling 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 recognizes the type of alarm and transmits it to the supervisory line, and to the control unit.

Characteristics of the heat detector:

  • Sensitivity degree and the temperature class comply with EN 54.
  • Regulation of alarm threshold which compensates the influence of the environment.
  • Indication of an alarm by means of the LED diode.
  • Additional LED diodes for the testing state.
  • External status indicator.
  • Integrated short-circuit isolator.
  • A casing with a low profile.
  • Operation in the addressable systems.
