Apollo ORB-OP-12001 Optical Smoke Detector with Flashing LED

Orbis Optical Smoke Detectors work on the well-established light scatter principle. The remarkable optical design of the Orbis Optical Smoke Detector enables it to respond to a wide spectrum of fires. The sensing chamber 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.
