Edwards SIGA-HCD Rate-of-rise Heat And Co Detector

The Signature Series Edwards SIGA-HCD detector brings advanced multi-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.

In general, the Edwards SIGA-HCD provides the best of both worlds with multisensor life safety monitoring. 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 Series detectors, the Edwards SIGA-HCD gathers analog information from its sensing elements and converts this data into digital signals. Also, to make an alarm decision, the detector’s onboard microprocessor measures and analyzes the heat 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 heat sensor independently from the CO sensor to determine whether to initiate a fire alarm, a life safety CO alarm, or both.
