Apollo ORB-OP-12001-APO Orbis Optical Smoke Detector

Apollo ORB-OP-12001-APO Orbis Optical Smoke Detector

The Orbis Optical Smoke Detector operates on the well-established light scatter principle. The sensing technology used is radically different from previous optical detectors and significantly reduces false alarms. Orbis operates on the well-established light scatter principle. The remarkable optical design of the Orbis optical smoke detector allows it to respond to a wide spectrum of fires. The sensing chamber of the Orbis optical smoke detector contains an optical sensor which measures back-scattered light as well as the more usual forward-scattered light.

Sensitivity to black smoke is greatly improved. The detector is calibrated so that Orbis is highly reliable in detecting fires but is much less likely to generate false alarms than earlier 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 the likelihood of a detector producing an alarm as a result of smoke from smoking materials or from another non-fire source.

Orbis® is a range of conventional detectors which has been developed and tested to create advantages for fire engineers and installers, as well as owners and users of buildings. Orbis is a range with modern styling and a mounting base that saves installation time. It is electrically compatible with Apollo Series 65 and previous ranges of conventional detector.

Orbis is a demonstration of Apollo’s commitment to the market for high quality conventional detectors for use in small to medium size installations. In developing this range Apollo has put ease of installation and reliability in daily operation at the forefront of considerations. The attractive and compact design means that Orbis will blend in well with all architectural styles.
