Apollo Orbis I.S. Optical Smoke Detector
£97.00 excl VAT
The Orbis IS Optical Smoke Detector works using the light scatter principle and is ideal for applications where slow-burning or smouldering fires are likely.
The Orbis I.S Optical Smoke Detector operates on the well-established light scatter principle. The remarkable optical design of the Orbis I.S. optical smoke detector allows it to respond to a wide spectrum of fires. The sensing chamber of the Orbis I.S. Optical Smoke Detector contains an optical sensor which measures back-scattered light. Sensitivity to black smoke is greatly improved.
The detector is calibrated so that it is highly reliable in detecting fires but is much less likely to generate false alarms than ionisation smoke detectors. The stability of the detector – high reliability, low false alarm rate – is further increased by the use of algorithms to decide when the detector should change to the alarm state. This removes likelihood of a detector producing an alarm as a result of smoke from smoking materials or from another non-fire source. The sensing chamber has been designed to keep out dust and other airborne contaminants.
