The AIR-Intelligence high-sensitivity smoke detection system (HSSD) provides superior early warning smoke detectors that adapt to virtually any environment. AIR-Intelligence HSSD continuously adapt their sensitivity to the environment in which they are installed, providing alarm thresholds which are `relative` to the background particle levels in the protected area, instead of placing the alarm threshold at a fixed level relative to ambient conditions. At any time, the detector`s performance remains constant, regardless of fluctuations in the normal background particle level. AIR-Intelligence detectors only respond to particle levels significantly above the expected background level, such as from a genuine fire situation.
