Black 12V hardwired carbon monoxide alarm detector with flush-mount installation and trim ring for RV or marine replacement applications.
The MTI Industry 62-542-BL-TR Safe-T-Alert alarm detector is a 12V hardwired carbon monoxide alarm designed for enclosed RV or marine interior spaces. It monitors for dangerous carbon monoxide levels and provides an audible warning when unsafe CO conditions are detected.
This black flush-mount version includes a trim ring, making it helpful for replacement installations where the previous detector left screw holes, wall marks, or an older cutout that needs extra coverage. It is intended for compatible 12V hardwired CO-only alarm locations.
Carbon monoxide can come from engines, generators, furnaces, water heaters, stoves, or nearby exhaust sources. A working CO alarm is especially important in sleeping areas, enclosed cabins, and RV living spaces where CO can build up without a visible warning.
Alerts occupants to dangerous carbon monoxide levels
Runs from the vehicle or vessel’s 12V DC electrical system
Installs into compatible recessed wall openings
Helps cover older screw holes and previous installation marks
MTI Industry 62-542-BL-TR is a carbon monoxide alarm detector only. It does not detect propane/LP gas, smoke, fire, or gasoline vapors. If replacing a combination CO/LP alarm, propane alarm, smoke alarm, relay model, or generator-shutdown model, confirm the correct replacement before ordering.
Disconnect 12V power before removing the old detector. Confirm the replacement location, wall cutout, wire routing, and mounting footprint match this flush-mount CO alarm. Install the trim ring as needed to cover previous screw holes or cutout edges, connect the detector according to MTI instructions, and test the alarm after installation.
Package Contents: • 1 MTI Industry / Safe-T-Alert 62-542-BL-TR carbon monoxide alarm detector • Black trim ring • Mounting hardware/instructions as supplied by current manufacturer packaging NOT Included — May Also Need: • Propane/LP gas alarm • Smoke alarm • Generator shutdown relay or interconnect components • Replacement wiring, connectors, fuse, or circuit repair parts • Additional wall repair materials or adapter plate • RV or marine engine, generator, furnace, appliance, or exhaust system diagnosis • Professional RV or marine electrical service This listing is for the carbon monoxide alarm detector with trim ring only unless otherwise stated.
Before ordering, confirm the old detector is a CO-only, 12V hardwired, flush-mount alarm. Compare the existing detector’s case size, wall opening, screw locations, wiring, trim coverage needs, color, and installation location. If the old system used interconnect, generator shutdown, or relay wiring, verify the correct replacement version before ordering.
If the CO alarm sounds or occupants experience headache, dizziness, nausea, weakness, confusion, or flu-like symptoms, move everyone to fresh air immediately and seek emergency help. Shut down engines, generators, furnaces, heaters, and other combustion sources if safe to do so, ventilate the area, and have the RV or vessel inspected before reuse. Do not ignore, disable, cover, paint, or relocate the alarm outside the manufacturer’s approved installation instructions.
