Edwards EST SIGA-IS Intelligent Ionization Detector – UL/ULC Listed 18/02 Sampling tubes rotate in 45-degreeESTs Signature Series Model SIGA IS Intelligent Ionization Smoke Detector gathers analog information from its smoke sensing element and converts it into digital signals. The detectors on board microprocessor measures and analyzes these signals. It compares the information to historical readings and time patterns to make an alarm decision. Digital filters remove signal patterns that are not typical of fires. Unwanted alarms are virtually eliminated.
