Leakbee R503 RV 2-in-1 CO & Propane Detector – 12V DC, 100dB Alarm, Flush Mount (Black)

Meet the Leakbee R503: a 2-in-1 RV detector

On the road, safety and simplicity matter. The Leakbee R503 combines carbon monoxide and propane gas detection in a single compact unit designed for RVs, motorhomes, travel trailers, and similar campers. With two independent sensors and a clear display, you can stay informed about potential risks without clutter or complexity. This 2-in-1 approach aims to provide timely indications of two common in-vehicle hazards, helping you create a comfortable and monitored space wherever you park.

Two independent sensors for RV safety

• CO sensor continuously monitors for elevated carbon monoxide levels from exhaust, appliances, or generators
• Propane gas sensor detects propane leaks in living areas, kitchens, or heating zones

Having separate sensors helps reduce cross-sensitivity and provides distinct signals for each type of risk. The system’s dual capability can offer clearer readings so you can respond appropriately in real-life scenarios, such as settling in for the night or cooking aboard.

Easy installation and flexible power

• Operates on 12V DC with a wide ±20% voltage tolerance for compatibility with most RV electrical setups
• Flush-mount design keeps surfaces neat and minimizes protrusions during travel
• Lever-nut connectors enable tool-free wiring, simplifying upgrades or removals

The R503 ships with a flush mount bracket, lever-nut connector, user manual, and mounting screws, making it straightforward to install within standard RV cutouts and mounting patterns.

Visual and audible alerts you can rely on

• LED display provides real-time readings of CO and propane levels for quick assessment
• 85 dB audible alarm sounds to alert occupants even if you’re away from the detector

When a reading indicates a potential risk, the combination of a bright readout and a loud alert helps you stay informed and prepared without overpromising results. Use it as part of an overall safety routine for the RV environment.
