Why are the optical flame detectors so important?
For many years optical flame detectors have been an integral part of automatic fire detection systems. Optical detectors can ‘see’ a fire from a long distance without the smoke or heat needing to get to the detector first. Light travels extremely fast so the detector ‘sees’ (reacts) extremely quickly to flaming fires that can be up to 65m away and only 1ft2 (0,01m2) in size. This feature makes optical flame detectors very effective in large open or critical areas where other fire detection methods would not work.
