Edward Fire Alarm System

Product Details:

The Signature Optica Series SIGA-OSCD smoke detector
brings advanced optical (photoelectric) 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.
The SIGA-OSCD provides a combination of optical detection for
the early detection of smoke, with the added element of carbon
monoxide sensing. 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.
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. Utilizing
dual optical wavelengths combined with multiple detection angles,
the SIGA-OSCD 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 detector also
analyzes the smoke sensor independently from the CO sensor to
determine whether to initiate a fire alarm, a life safety CO alarm,
