The Signature Series SIGA-PCD detector brings advanced multisensor technology to a practical design that increases efficiency,
saves installation time, cuts costs, and extends life safety and
property protection capabilities. Continuous self-diagnostics ensures reliability over the long-haul, while environmental compensation helps reduce maintenance costs.
The SIGA-PCD 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 Series detectors, the SIGA-PCD gathers analog
information from its sensing elements and converts this data into
digital signals. To make an alarm decision, the detector’s on-board
microprocessor measures and analyzes smoke sensor readings
and compares this information to historical data. Digital filters remove signal patterns that are not typical of fires, thus virtually eliminating unwanted alarms. 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, or both.
