Combination Carbon Monoxide/Propane Alarm | Black, Flush Mount, 12V DC Hardwired

Keep your rig's cabin monitored for two of the most common RV hazards with this combination carbon monoxide/propane alarm from MTI Industries. It hardwires directly into your coach's 12V DC system and flush-mounts into the wall or cabinet face, so there's no bulky housing sticking out — just a low-profile black unit that blends into darker interior finishes.

• Combination sensor detects both carbon monoxide and propane (LP gas)
• Flush-mount design sits nearly flat against the wall or cabinet
• Hardwired 12V DC — no battery swaps needed
• Black housing matches darker interior finishes
• Direct-fit replacement for MTI Industries model 45-742-BL

Whether you're replacing an existing 45-742-BL or adding CO/propane monitoring to your build, this alarm is sized and wired to drop into the same mounting cutout.
