EST Edwards SIGA-PS Intelligent Addressable Photoelectric Sensor Head USED

Edwards/ EST smoke detector SIGA-PS

The Signature Series Model SIGA-PS Intelligent Photoelectric Smoke Detector gathers analog information from its smoke sensing element and converts it into digital signals.  The detector’s 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.  The microprocessor in each detector provides four additional benefits – Self-diagnostics and History Log, Automatic Device Mapping, Stand-alone Operation and Fast, Stable Communication.
