Series 65 Conventional Heat Detector

Series 65 A1R (50) Heat Detector - Rate of Rise Series 65 BR Heat Detector Series 65 CR Heat Detector Series 65 CS Heat Detector

The Series 65 Heat Detector monitors temperature by using a dual thermistor network which provides a voltage output proportional to the external air temperature. There are four classes of heat detectors in the Series 65 range designed to suit a wide variety of operating conditions.

  • Can be used for applications where smoke detectors are unsuitable
  • Ideal in environments that are dirty or smokey under normal conditions
  • Wide operating voltage
  • Flashing LED and magnet operated test switch option
