Safe-T-Alert Carbon Monoxide, Smoke & Fume Detectors

Safe-T-Alert: Purpose-Built CO, Smoke & Fume Protection for RVs and Marine Environments

When you're living and traveling in a confined space — whether that's a Class A motorhome cruising down the highway or a powerboat anchored overnight — the stakes for gas and carbon monoxide detection are uniquely high. Safe-T-Alert, manufactured by MTI Industries, Inc., has spent decades engineering alarms specifically for these mobile and marine environments, making them one of the most trusted names in the Carbon Monoxide, Smoke & Fume Detectors category.

A Heritage of Mobile Safety

Safe-T-Alert's roots in RV and marine safety run deep. The brand has been protecting travelers since 1987, developing a comprehensive lineup of CO alarms, smoke detectors, gas fume detectors, and combination dual-sensor alarms engineered to handle the realities of life on the road or water. Unlike home detectors designed for static indoor environments, Safe-T-Alert units are built to withstand the vibration, shock, humidity, and extreme temperatures encountered on the move.

Key Product Lines and Technologies

Safe-T-Alert's detector lineup covers a wide range of use cases and installation types. Their flagship series include:

• 62 Series Carbon Monoxide Alarms — Available in 12V and 24V versions for both RV and marine applications. NMMA-listed marine variants feature a compact, space-saving flush-mount design engineered for the harsh saltwater environment. Models with relay outputs are available for integration with vessel alarm systems.
• FX-4 Carbon Monoxide Alarm — A low-voltage, hardwired marine CO alarm featuring advanced sensing technology and a loud 85 dB alert. Its durable construction is built to withstand vibration, shock, and temperature extremes, making it a go-to replacement for aging marine CO detectors.
• 45 Series Combo Alarms — Dual-sensor units that simultaneously detect both carbon monoxide and propane/LP gas, meeting RVIA/NFPA requirements and listed to UL 1484 RV and UL 2034 RV standards. These are ideal for any RV where both gas types are a concern.
• 85 Series Combo Alarms — A slim, universal-fit dual CO and LP gas alarm designed as a direct replacement for virtually all major RV alarm brands, including legacy units from Atwood and Dometic.
• SA-340 Battery-Powered CO Detector — Features a sealed-in lithium battery with a 5-year lifespan, eliminating the hassle of battery replacement in hard-to-reach installations.
• Gas Fume / Bilge Detectors — Remote-sensor marine units that monitor bilge and engine compartments for dangerous gas vapor accumulation, providing a critical layer of protection aboard powerboats.

Smart Features That Matter in Mobile Environments

Safe-T-Alert's CO and combination alarms are loaded with features tailored to the RV and boating lifestyle. An Alarm Mute button silences the detector while an enclosed space is being ventilated, preventing unnecessary panic — but a Rapid Recovery Sensor automatically reactivates the alarm if dangerous gas levels persist after silencing. The proprietary Memory Scan™ technology found in select models retains the CO level that originally triggered the alarm, providing important information even after the space has been ventilated.

Some models also feature two-level CO detection, providing an early-warning alert at moderate concentrations to better protect children, seniors, and other at-risk individuals before levels become critically dangerous.

Certifications and Standards Compliance

Safe-T-Alert alarms meet the stringent requirements set by RVIA and NFPA for recreational vehicle safety. Marine models carry NMMA listing as approved components. Dual CO/propane alarms are listed to UL 1484 RV and UL 2034 RV standards. This level of certification matters enormously in small, sealed living spaces where a false negative can be fatal.

With 14 products spanning dedicated CO alarms, smoke detectors, gas fume detectors, and dual combination units — in both 12V and 24V configurations — Safe-T-Alert provides one of the most complete mobile safety alarm ecosystems available.
