Edwards (SIGA-OSD) Intelligent Smoke Detector
The Edwards Signature Optica Series SIGA-OSD smoke detector brings advanced optical sensing 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, while environmental compensation helps reduce maintenance costs.
Like all Signature Optica Series detectors, the SIGA-OSD is 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 are not representative of actual smoke. Particle data is input into digital filters which feed a series of ratios removing signal patterns that are typical of nuisance sources, thus reducing unwanted alarms. To make an alarm decision, the detector’s on-board microprocessor measures and analyzes all optical sensor readings and compares this information to preprogrammed settings.
The SIGA-OSD detector is compatible only with control panels using a Signature Loop controller.
This detector is the replacement for the Edwards SIGA-PS, and the Edwards SIGA-PD
