RV Safe RVLP-2B Propane Gas Alarm
Updated June 17, 2026
The RV Safe RVLP-2B is a 2-wire combination propane (LP) and carbon monoxide (CO) alarm designed for recreational vehicles. It uses an advanced electrochemical CO sensor to detect dangerous gas levels while minimizing false alarms. The unit is ETL listed to UL 1484 and UL 2034, surface-mounted, and includes adapter brackets to replace most existing RV alarms.

How It Works
The RVLP-2B continuously monitors the air for propane and carbon monoxide. When hazardous concentrations are detected, it sounds an audible alarm. Its low-power gas detection circuitry extends RV battery life compared to competitor alarms. The unit operates on a 2-wire connection (12V DC) and has a 5-year service life.
Installation Notes
This alarm is designed for surface mounting in an RV interior, typically near the floor for propane detection (propane is heavier than air) and at breathing height for CO. It connects to a 12V DC power source via two wires. The included universal mounting brackets allow replacement of most existing RV alarms without additional hardware.
Common Failure Symptoms
The most common indication of end-of-life is a periodic chirp (typically every 30-60 seconds) after 5 years of use. False alarms are rare due to the selective CO sensor, but exposure to strong chemicals or gases may trigger a temporary alarm. If the unit fails to power on, check the 12V connection and fuse.
