Description

The Edwards Est SIGA-PD optical smoke detector brings advanced sensing technology to a practical design that increases efficiency, saves installation time, cuts costs, as well as extends life safety and property protection capabilities. Continuous self-diagnostics ensure reliability over the long haul, while environmental compensation helps reduce maintenance costs.

In fact, like all Signature Series detectors, the Edwards Est SIGA-PD is an intelligent device that gathers analog information from its optical sensor, converting this data into digital signals. Also, to make an alarm decision, the detector’s onboard microprocessor measures and analyzes sensor readings and compares this information to historical data. Digital filters remove signal patterns that are not typical of fires, thus virtually eliminating unwanted alarms.

Besides, the SIGA-PD detects extremely small particles of combustion and triggers an alarm at the first sign of smoke. Thanks to its high-performance forward-scattering reflective response technology, the photoelectric smoke sensor responds quickly and reliably to a wide range of fire types, especially slow-burning fires fuelled by combustibles typically found in modern multi-use buildings.
