Description

Edwards Est SIGA2-COS carbon monoxide detectors bring advanced sensing technology to a practical design that increases efficiency, saves installation time, cuts costs, as well as extends life safety capabilities. Continuous self-diagnostics ensure reliability over the long-haul, while advanced electrochemical CO sensing technology provides performance benefits that keep occupants safe from the “silent killer”

Also, like all Signature Series detectors, the Edwards Est SIGA2-COS is an intelligent device that gathers analog information from its CO sensor, converting this data into digital signals. Besides, to make an alarm decision, the detector’s onboard microprocessor measures and analyzes sensor readings over time. Digital filters remove signal patterns that are not typical of life safety events, thus virtually eliminating unwanted alarms.

In general, the SIGA2-COS includes an advanced carbon monoxide sensor and daughterboard. When the electrochemical cell reaches its end of life after approximately six years, the detector signals a trouble condition to the control panel. The sensor/daughterboard module is field-replaceable.
