Optical smoke sensor
WebFire detection is based on various properties of fire such as smoke emission, a rise in temperature and optical radiation emission. In large spaces or outdoor environments, optical flame detection is one of the fastest and most reliable methods of detection. WebOptical beam smoke detectors work on the principle of light obscuration, where the presence of smoke blocks some of the light from the beam, typically through either …
