The Edwards SIGA-PD is an intelligent photoelectric smoke detector that uses an optical sensing chamber to detect smoke
The detector's microprocessor analyzes sensor readings and compares them to historical data to decide whether to trigger an alarm.
Digital filters remove signal patterns that are not typical of fires, which can help eliminate unwanted alarms.
