Edwards SIGA-OSHCD Multi Sensor

The Edwards SIGA-OSHCD smoke detector brings advanced optical 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 general, the Edwards SIGA-OSHCD provides the best of all worlds with comprehensive life safety monitoring. The combination of optical smoke detection with rate-of-rise heat sensing technology provides efficient identification of smoldering fires, as well as fast flaming fires. With the added element of CO monitoring, this detector pulls double duty: continually monitoring the environment for signs of fire, as well as its invisible yet deadly companion— carbon monoxide.

Like all Signature Optica Series detectors, the SIGA-OSHCD 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-OSHCD 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 is typical of nuisance sources, thus reducing unwanted alarms.
