Silent Knight SK-FIRE-CO-W Smoke and Carbon Monoxide DetectorSK FIRE CO W is a plug in, addressable device that provides both fire and carbon monoxide (CO) detection. The detector combines four separate sensing elements to sense multiple components of a fire: smoke, CO, light flame, and heat. This approach enables enhanced sensitivity to real fire with heightened immunity to nuisance particulates. For CO, the detectors electrochemical sensing cell creates a separate signal for life safety CO detection. DATA
