<h3>About MTI Industries & Safe-T-Alert™</h3><p>When you’re miles from the nearest town — parked at a mountain overlook in your RV or anchored in a quiet cove on your boat — safety equipment isn’t optional, it’s essential. MTI Industries has built its reputation on exactly that principle. As the manufacturer behind the trusted <strong>Safe-T-Alert™</strong> brand, MTI Industries specializes in propane, carbon monoxide, and smoke alarms designed specifically for the demands of recreational vehicles and watercraft.</p><p>Unlike household detectors that are engineered for climate-controlled, stationary environments, Safe-T-Alert™ alarms are purpose-built to endure the unique challenges of life on the road and water. According to the brand, their alarms are built to handle vibration, shock, humidity, and extreme temperatures encountered along the road, all while conserving battery power. That focus on environmental durability is what sets MTI Industries apart from general-purpose alarm manufacturers.</p><h3>A Full Line of Life-Safety Detection Products</h3><p>MTI Industries offers a comprehensive range of detection solutions, with products tailored for both RV owners and boaters. Their lineup includes standalone carbon monoxide alarms, dedicated propane/LP gas alarms, smoke and fire alarms, and popular <strong>dual-detection alarms</strong> that monitor for both carbon monoxide and propane gas simultaneously in a single, space-saving unit. Many models operate on hardwired 12V DC power — the standard electrical system found in RVs and boats — eliminating the need for battery replacements and ensuring continuous, uninterrupted protection.</p><p>For RV owners, Safe-T-Alert™ products are designed to meet RVIA (Recreational Vehicle Industry Association) and NFPA (National Fire Protection Association) standards, and select models are certified to UL 1484 and UL 2034 standards for propane and CO detection respectively. These certifications matter because they verify that a detector’s performance has been independently validated against rigorous benchmarks — not just the manufacturer’s own claims.</p><h3>Trusted by RV and Marine Communities</h3><p>Whether you’re equipping a Class A motorhome, a fifth-wheel trailer, a pontoon, or an offshore vessel, MTI Industries offers a Safe-T-Alert™ model engineered for your specific environment. The brand’s series-based product structure — from the compact 25 Series to the full-featured 85 Series — makes it straightforward to find the right level of protection for your application and installation requirements. From flush-mount designs for clean interior installations to surface-mount options for quick retrofits, there is a Safe-T-Alert™ format for virtually every setup.</p><p>Explore our full selection of MTI Industries <a href="/7469-mti-industries-carbon-monoxide-smoke-fume-detectors-200239">Carbon Monoxide, Smoke & Fume Detectors for RVs</a> and <a href="/7469-mti-industries-carbon-monoxide-smoke-fume-detectors-201778">Carbon Monoxide, Smoke & Fume Detectors for Marine applications</a> to find the right Safe-T-Alert™ alarm for your rig or vessel.</p>

Only issue I had was that order could not be completed on Amazon, stating "items cannot ship to your location." I simply went to your website and ordered items. So a little inconvenient, but no biggie.
