Product Overview
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. Reduced incidences of false alarms. Increased reliability of detection. Approvals: EN54-5
