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. Utilizing dual optical wavelengths combined with multiple detection angles, the SIGA-OSCD differentiates particles that are not representative of actual smoke. Like all Signature Optica Series detectors, the SIGA-OSCD is an intelligent device that gathers analog information from multiple optical sensors, converting this data into digital signals.

The result is a detector that pulls double duty: continually monitoring the environment for signs of fire, as well as its invisible yet deadly companion, carbon monoxide. The SIGA-OSCD provides a combination of optical detection for the early detection of smoke, with the added element of carbon monoxide sensing. Continuous self-diagnostics ensure reliability over the long-haul, while environmental compensation helps reduce maintenance costs. The Signature Optica Series SIGA-OSCD 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.
