LP gas alarms have a limited service life and should be replaced when expired, damaged, malfunctioning, or no longer passing test procedures. United RV Parts notes a 5-year service life beginning once the alarm is powered on or installed. Always follow the instructions supplied with the alarm and replace expired detectors promptly.
Disconnect 12V power before removing the old detector. Mount the replacement alarm in an approved RV propane detector location, connect to a dedicated 12V DC circuit that cannot be switched off, and test the alarm after installation according to the included instructions.

Confirm the existing detector is a 12V hardwired LP/propane alarm and compare the mounting style, case size, wall opening/coverage, wiring, and installation location. This model is an LP gas detector only and does not replace a combination LP/CO alarm.
If the alarm sounds or propane odor is present, evacuate the RV, shut off propane if safe to do so, ventilate the area, avoid flames/sparks/electrical switches, and have the propane system inspected before use. Do not ignore, disable, cover, paint, or relocate the alarm outside the manufacturer’s approved installation instructions.
