Safe-T-Alert FX-4 Carbon Monoxide Alarm - 2-Pack

The Safe-T-Alert FX-4 Carbon Monoxide Alarm 2-Pack is essential safety equipment for any vessel operator who spends extended time in an enclosed cabin with running engines or generators. Carbon monoxide (CO) is a silent, odorless killer that accumulates in boat cabins, particularly during idle periods or when running auxiliary power systems—a hazard many experienced boaters have learned to respect the hard way. This two-unit set ensures you have redundant detection coverage throughout your boat, meeting modern marine safety standards and providing peace of mind for you and your crew.

The FX-4 features low-voltage hard-wired installation, integrating seamlessly with your boat's 12V electrical system without relying on battery replacements that can fail at critical moments. Each unit delivers a full 5-year service life—exceeding the lifespan of comparable models like the CMD-4M and CMD-3M—before requiring replacement. The alarm triggers audible alerts at dangerous CO concentrations, providing immediate warning before symptoms develop. Hard-wired configuration ensures permanent, reliable operation without the maintenance burden of battery-dependent detectors, a critical advantage in marine environments where salt spray and corrosion accelerate battery degradation.

This two-pack delivers complete cabin protection for cruising sailboats, motor yachts, and cabin cruisers where engine compartments are located near living quarters. If you're replacing aging CO alarms that have exceeded their 5-year design life, this set eliminates guesswork—both units arrive ready to hardwire into your 12V bus. Installation requires basic marine electrical knowledge or professional assistance, but the permanent mounting eliminates the false security of portable detectors that shift position or get forgotten. Any boater logging significant overnight hours in an enclosed cabin should consider redundant CO detection non-negotiable, not optional.
