Fireboy-Xintex CO Alarm 12/24V DC - Black

The Fireboy-Xintex CO Alarm 12/24V DC in black is a marine-grade carbon monoxide detector engineered for serious boaters and anglers who spend extended hours on the water. Carbon monoxide poses a silent threat in enclosed cabin spaces—a colorless, odorless gas produced by generators, engines, and fuel-burning heaters that can incapacitate or kill occupants within minutes.

This compact alarm is your first line of defense, offering reliable detection in the harsh marine environment where galvanic corrosion and saltwater exposure challenge standard equipment. Built to military electrochemical sensor standards, the Fireboy-Xintex CO Alarm operates on either 12-volt or 24-volt DC power, making it compatible with most vessel electrical systems. The sensor actively monitors ambient air for dangerous CO concentrations and triggers a loud, unmistakable alarm when levels reach hazardous thresholds—typically 35 ppm over 8 hours or 400 ppm over 15 minutes, depending on exposure duration.

Its compact footprint (4 × 2 × 6 inches) and weatherproof black housing mean minimal cabin footprint without sacrificing durability; the unit resists moisture, vibration, and temperature swings typical of marine use. Installation is straightforward for any boater—mount it in your cabin, galley, or sleeping quarters where it can sample air freely, then wire it directly to your vessel's 12V or 24V DC system. Anglers who run generators for onboard freezers, trolling motors, or cabin climate control benefit from this essential safety device.
