Enhance Marine Safety with Safe-T-Alert FX-4 Carbon Monoxide Alarm

The Safe-T-Alert FX-4 Carbon Monoxide Alarm is designed to provide reliable protection for your marine environment. This 2-pack offers peace of mind for both recreational and commercial boats. Replacing your outdated CO alarms, the FX-4 features a low voltage hard-wired alarm system, ensuring continuous monitoring without the hassle of replacing batteries. With a full 5-year service life, it outperforms other models like the CO Sentinel CMD-4M, which have reached their end of life.

Key Features and Specifications

The Safe-T-Alert FX-4 is fully compliant with ANSI / UL STD 2034 - Marine and meets ABYC A-24 standards, making it a NMMA listed component. This alarm is the most reliable choice for your marine DC electrical system or marine-grade batteries, ensuring there are no missing or dead batteries to replace. Its proven sensing technology prevents nuisance alarms, reducing confusion and the risk of disconnected detectors. The advanced technology includes an alarm mute button that silences the alarm while the boat is ventilated, with a rapid recovery sensor that resets when silenced and reactivates if dangerous levels of CO remain. The alarm is loud, with an 85 dB sound to alert you to CO danger, and its compact case measures 2.5”W x 3.5”H x 1.25”D.

Practical Uses and Benefits

The Safe-T-Alert FX-4 Carbon Monoxide Alarm is ideal for any marine application where CO detection is crucial. Its features make it a standout choice for ensuring the safety of your crew and passengers. With no bags or tags included, the alarm is ready to install and use right out of the box. The 12v voltage input range and the absence of a generator shutdown feature make it versatile for various marine electrical systems. With dimensions of 2"H x 8"W x 10"L and a weight of 1.2 lbs, the alarm is both easy to install and transport. Trust the Safe-T-Alert FX-4 to protect your marine environment and keep you and your loved ones safe.
