Silent Knight SK-FIRE-CO-W is a plug-in, addressable device that provides both fire and carbon monoxide (CO) detection. Also, the Silent Knight SK-FIRE-CO-W detector combines four separate sensing elements to sense multiple components of a fire: smoke, CO, light/flame, and heat. Besides, 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 as well as enhanced sensitivity to a real fire. This ability to reject certain nuisance alarm triggers, such as theater smoke, supports the use of the fire/CO detector in applications where moderate to heavy nuisance conditions exist that might cause single-sensing detectors to a false alarm.
