Marine Technologies FX-4-Marine Carbon Monoxide Alarm 12V DC Hard Wire Surface Mount White

The Marine Technologies Safe-T-Alert FX-4-Marine is a hard-wired carbon monoxide alarm purpose-built for marine environments. Carbon monoxide is an odorless, colorless gas that can be lethal in enclosed boat cabins, making reliable early detection essential for crew safety aboard any vessel.

This alarm connects directly to the boat's 12-volt DC electrical system, providing continuous, uninterrupted protection without the risk of missing or dead batteries. The compact white surface-mount housing measures just 2.5"W x 3.5"H x 1.25"D, making it easy to install in cabins, berths, or any enclosed onboard space.

Key Features:

• NMMA Listed Component — Recognized by the National Marine Manufacturers Association
• 12V DC Hard Wire — Powered directly by the vessel's DC electrical system; no battery replacement required
