Black 12V RV combination carbon monoxide and propane gas alarm detector with flush/recessed mount installation.
The MTI Industry 25-742-BL Safe-T-Alert alarm detector combines carbon monoxide and propane/LP gas detection in one 12V RV safety device. It is designed for RV interiors where both CO and LP gas protection are needed.
This black flush/recessed-mount model is intended for compatible RV wall cutouts and 12V hardwired detector circuits. It is a standard CO/LP alarm detector, not an LP-only alarm and not the relay/solenoid-control version.
Detects carbon monoxide and propane gas
Runs from the RV’s 12V DC electrical system
Compact recessed-style installation for compatible RV wall openings
Listed to UL 2034 RV and UL 1484 RV standards
The 25-742-BL is a combination CO and LP gas alarm detector, not an LP-only propane detector. Do not use this in place of a relay model if the RV requires detector-controlled propane shutoff/solenoid wiring. Match the original detector model, wiring, and mounting cutout before ordering.
Disconnect 12V power before removing the old detector. Verify the replacement location, wall cutout, and wiring match this flush-mount 12V CO/LP alarm detector. Connect the new alarm according to the included MTI instructions and test the alarm after installation.

If the alarm sounds, carbon monoxide symptoms are present, or propane odor is detected, evacuate the RV immediately, shut off propane if safe to do so, avoid flames/sparks/electrical switches, and have the RV inspected before use.
