Appearance: affinity, round, consistent, fusion.
Performance: Smoke alarms save lives. If there is a fire in your home, smoke spreads fast and you need smoke alarms to give you time to get out. Due to technical limitations, smoke detectors in market are easy to false alarm which result smoke detectors are removed or powered off. Particles of fire smoke are distributed in diameters of 0.01 to 1 micron, usually in a log-normal distribution, with particles of 0.1-1 micron contributing the most to scattered light energy. Since the advent of photoelectric smoke detectors in the 1970s, the frequency of light sources commonly used is about 0.9 microns, according to the meter theory of particle optical scattering, 0.9 micron wavelengths of light sources can basically only measure 0.3 to 3 microns of meters of scattered light energy, which results in scattered smoke detectors are particularly sensitive to larger smoke particles, The rear-scatter detector can improve the balance of the test fire response, but it still does not solve the problem of the response of smoke particles below 0.3 microns. In recent years, many materials such as Teflon, polyimide and other fire smoke with an average particle size of 0.1-0.3 microns, for 0.9 microns of infrared light, its scattering light energy is very weak. This detector uses red & blue dual-wavelength chamber, the forward and rear scattering light path organic combination, and the use of different wavelengths of light-emitting devices, so through scattering signal processing, can identify particle sizes, so as to distinguish between fire soot and dust, water vapor, Micro-smoke with particle sizes as small as 0.15 microns can be detected, and false caused by water vapor and dust can be effectively avoided. Realize early detection, early treatment and reduce fire loss.
