Silent Knight SK-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 detector’s electrochemical sensing cell creates a separate signal for life safety CO detection.

Multiple sensors and communication can greatly reduce nuisance alarms compared to single sensing methods. Sophisticated algorithms maximize the advantages of all four sensor types creating our best detection strategy offering heightened immunity to nuisance particulate and enhanced sensitivity to real fire.

When paired with the B200S-WH sounder base or B200S-LF-WH low frequency sounder base, the Silent Knight SK-FIRE-CO-W can generate unique alarms for fire and CO events (bases sold separately). Now available with a modern white finish and a 10-year CO cell. Compatible with 5000 and 6000 Series addressable fire alarm control panels using SK protocol.
