The Orbis IS 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 IS 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.
