Apollo ORB-HT-51157-APO Orbis I.S. Heat Detector (A1S) The Discovery Heat Detector featuresOrbis I. S. Heat Detector (A1S) The Orbis I. S. Heat Detector monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. Can be used for applications where smoke detectors are unsuitable Ideal for environments that are dirty or smoky under normal conditions Reduced incidences of false alarms Increased reliability of detection
