Orbis Heat Detector

Product Overview

The Orbis Heat Detector monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. There are seven classes of heat detectors in the Orbis 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 smoky under normal conditions
  •  Reduced incidence of false alarms
  •  Increased reliability of detection
