C4 EN54-7 Optical detector

C-Tec ActiV Optical Smoke Detector - C4416

The C4416 Optical Smoke Detector uses an infrared light source and a photodiode to detect smoke. In the absence of smoke, light passes in front of the photodiode in a straight line. When smoke enters the optical chamber across the path of the infrared beam, light is scattered by particles of smoke in all directions, some of which falls on the photodiode thus triggering the alarm. Optical detectors are typically used in escape routes, living areas, bedrooms and enclosed spaces to give an early indication of fire. They are particularly effective at detecting slow burning fires (such as those caused by overheated electrical wiring or smouldering materials) which tend to generate larger particles of visible smoke.
