FX-4-Marine Carbon Monoxide Alarm, White Surface Mount 12 VDC Hard-Wire for Marine Use

The FX-4-Marine Carbon Monoxide Alarm is a hard-wired, 12 vDC carbon monoxide detector listed for marine use, designed to warn boat owners and passengers of dangerous CO buildup in cabins, engine compartments, and other enclosed spaces aboard a vessel. It is finished in white and installs as a surface-mount unit, making it suitable for cabin walls, helm stations, or other flat interior surfaces where a visible, permanently wired alarm is needed. Because it runs on the boat's 12 vDC electrical system rather than disposable batteries, it is intended to operate continuously as part of the vessel's onboard safety systems, reducing the risk of a dead-battery gap in protection that can occur with battery-only alarms. As a unit specifically listed for marine use, it is built to handle the environment aboard a boat, where humidity, vibration, and engine exhaust make carbon monoxide monitoring especially important. This alarm is a straightforward safety addition for any boat with an enclosed cabin, generator, or inboard/outboard engine where exhaust gases could accumulate. It is compact and lightweight at 0.5 pounds, simplifying mounting in tight marine interior spaces.
