The Ajax Systems Protect 2 wireless carbon monoxide detector activates an audible and visual alarm when it detects a dangerous concentration of CO. Its built-in siren and critical notifications via Ajax apps alert you to the danger. It can operate independently or as part of an Ajax security system.

The detector filters out false alarms using real-time analysis and communicates with the hub via the Jeweller protocol. The replaceable batteries provide up to 7 years of operation.
