The SK-FIRE-CO is a plug-in, addressable device that provides both fire and carbon monoxide (CO) detection. The SK-FIRE-CO-W is an addressable combination fire and CO detector that can detect and send separate signals for fire and CO. This multi-criteria detector uses four sensing technologies (photoelectric, infrared, heat, and CO) to accurately detect fire and CO alarm conditions with a high immunity to false alarms. When paired with the B200S-WH sounder base or B200S-WH-LF low frequency sounder base, the 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.
