Edwards EST SIGA-OSD Intelligent Smoke Detector

The Edwards EST SIGA-OSD smoke detector brings advanced optical (photoelectric) technology to a practical design. That increases efficiency, saves installation time, cuts costs. And extends life safety and property protection capabilities. Continuous self-diagnostics ensure reliability over the long haul, wh ile environmental compensation helps reduce maintenance costs.

Like all Signature Optica Series detectors, the Edwards EST SIGA-OSD i s an intelligent device. That gathers analog information from multiple optical sensors, converting this data into digital signals. Utilizing dual optical wavelengths combined with multiple detection angles. The SIGA-OSD differentiates particles that a re not representative of actual smoke. Particle data i s input into digital filters wh ich feed a series of ratios removing signal patterns. That a re typical of nuisance sources. Reducing unwanted alarms. To make an alarm decision, the detector’s onboard microprocessor measures. And analyzes all-optical sensor readings and compares this information to preprogrammed settings.
