Abstract

A system and method of detecting smoke including establishing a baseline measurement for each of at least three overlapping sensing volumes; comparing a measured reading within each of the at least three sensing volumes and the baseline measurements to determine whether the measured reading is within a sensing threshold, and annunciating a warning signal if the difference is outside the sensing threshold.
