The FS20X exhibits faster false-alarm free response to firesover a wider temperature range and with a much longer detection range compared to conventional UV/IR detectors.
Conventional and older technology UV/IR detectors, using narrow band 4.3 micron IR sensors, will not respond to smoky fires or if the detector lens is contaminated with oil and other substances since both UV and 4.3 micron signals are attenuated, obscured or absorbed by thick smoke or detector lens contaminations. All UV sensors will be attenuated to some degree. Also, these old technology UV/IR detectors will not alarm to any fire if they are installed behind ordinary window glass
