The Signature Series Model SIGA-PHS Intelligent 3D Multisensor Detector gathers analog information from each of its two fire sensing elements (photoelectric and heat) and converts it into digital signals.
The detector’s on-board microprocessor measures and analyzes these signals separately with respect to a third element - Time. We call this technology 3D. It compares the information to historical
readings, time patterns, and several known fire characteristics to make an alarm decision. Digital filters remove signal patterns that are not typical of fires.
