This 12-volt carbon monoxide (CO) alarm protects RV occupants with a sealed lithium battery that requires no replacement for the life of the detector. Advanced micro-current technology minimizes battery drain, ensuring years of dependable operation in harsh mobile environments.

The mute button silences the alarm while you ventilate your RV, and the rapid-recovery sensor resets automatically once CO levels drop—or reactivates if dangerous levels persist. Meets RVIA and NFPA standards, and carries UL 2034 RV certification.
