Manufacturer

Safe-T-Alert

<h3>Protecting RVers and Boaters Since 1987</h3><p>Safe-T-Alert has earned its reputation as a trusted name in recreational vehicle and marine safety systems over nearly four decades of reliable service. Manufactured by MTI Industries Inc., the Safe-T-Alert brand specializes in propane, carbon monoxide, and smoke alarms for recreational vehicles and boats. What sets this brand apart is its deep understanding of the unique challenges these environments present—from extreme temperature fluctuations and constant vibration to humid, corrosive marine conditions.</p><h3>Engineering for Harsh Environments</h3><p>When you're traveling in an RV or spending time aboard a boat, standard household safety devices simply won't suffice. Safe-T-Alert products are purpose-built to withstand the rigors of mobile recreation. As part of MTI Industries, the company manufactures detectors with the most accurate sensing technology currently available. The brand's various product series—including the 30 Series, 35 Series, 62 Series, and 85 Series—offer both flush-mount and surface-mount options designed to fit seamlessly into different RV and marine installations without compromising living space.</p><h3>Comprehensive Protection Against Silent Threats</h3><p>The dangers of carbon monoxide poisoning and propane leaks are particularly acute in confined spaces like RVs and boat cabins. Carbon monoxide is an odorless, colorless gas produced by fuel-burning appliances such as generators, furnaces, and cooking equipment. Even a properly functioning propane system can develop leaks over time due to vibration and wear. Safe-T-Alert addresses these risks with specialized detection technology that continuously monitors air quality and triggers immediate alerts when dangerous levels are detected. Many of the brand's dual-function alarms can simultaneously monitor both carbon monoxide and propane, providing comprehensive protection in a single, space-efficient device.</p><h3>Smart Features for Peace of Mind</h3><p>Beyond basic detection, Safe-T-Alert incorporates thoughtful features that enhance usability and safety. Some Safe-T-Alert carbon monoxide alarms have two levels: low and high, with the first alerting you of moderate levels of CO to help protect children, seniors, and other people who are in the high risk groups. The alarm mute function allows users to temporarily silence alerts while ventilating the space, but rapid recovery sensors ensure the alarm reactivates if dangerous levels persist. Most models operate on 12-volt DC power systems standard in RVs and boats, drawing minimal current while providing continuous protection.</p><h3>A Legacy of Reliability</h3><p>Family owned since 1979, Safe T Alert by MTI Industries has been dedicated to reliably keeping outdoors enthusiasts safe for decades. The brand's commitment to quality is evident in its adherence to rigorous industry standards, including RVIA/NFPA requirements, UL 1484 for RV gas alarms, and UL 2034 for residential carbon monoxide detectors. This combination of engineering expertise, real-world testing, and regulatory compliance has made Safe-T-Alert a go-to choice for RV manufacturers, boat builders, and safety-conscious outdoor enthusiasts who refuse to compromise when it comes to protecting their families and fellow travelers.</p>
