The Signature Series model SIGA-OSD Series Intelligent Optical Smoke Detector is an intelligent device that uses an advanced optical sensing chamber to detect smoke. The detector determines whether to signal a fire alarm condition by analyzing the data from the sensing chamber to discriminate between fire and non-fire sources.. The SIGA-OSD detects particles from a wide range of combustion sources and will trigger an alarm when smoke density in the chamber reaches preprogrammed level. Thanks to its high-performance reflective response technology, the smoke sensor responds quickly and reliably to a wide range of fire types, including both fast and slow burning fires fueled by combustibles typically found in modern.
Edwards EST SIGA-OSD is a plug-in Optical Smoke Detector compatible only with control panels using a Signature Loop controller.. SIGA-OSD is a photoelectric smoke detector that uses multiple optical sensors and digital filters to reduce nuisance alarms. It has self-diagnostics, environmental compensation, and automatic device mapping features.
