Orbis Intrinsically Safe Heat Detectors monitor temperatures by using a single thermistor network which provides a voltage output proportional to the external air temperature. Heat detectors are used in applications where smoke detectors are unsuitable.
The Orbis Intrinsically Safe Heat Detector range incorporates seven heat detectors classes to suit a wide variety of operating conditions. All heat detectors in the Orbis Intrinsically Safe range are tested as static or rate-of-rise detectors and are classified as A1R, A1S, A2S, BR, BS, CR, and CS.
