2. Safety Information
Please read and understand all safety instructions before installing or operating this device. Failure to follow these instructions may result in property damage, injury, or death.
- This alarm is designed for 12V DC power systems only. Do not connect to AC power.
- Ensure proper polarity during wiring (red to positive, black to negative) to prevent damage.
- Do not paint the alarm. Paint can clog the sensor openings and interfere with proper operation.
- The alarm will not operate without power. Ensure a continuous 12V DC power supply.
- Test the alarm regularly as described in the maintenance section.
- Replace the alarm 60 months (5 years) after its first power-on date. An 'E' displayed on the screen indicates end-of-life.
- In case of an alarm, immediately ventilate the area and investigate the source of the leak.
3. Setup and Installation
The Leakbee R502 offers versatile installation options with included brackets. Choose the bracket that best suits your RV's interior.
3.1 Choosing an Installation Location
- Install the alarm approximately 4-12 inches (10-30 cm) from the floor. Propane gas is heavier than air and tends to settle low. Carbon monoxide mixes with air.
- Avoid installing near windows, doors, or vents where drafts could affect sensor readings.
- Do not install near cooking appliances, furnaces, or other heat sources.
- Ensure the alarm is not obstructed by furniture or curtains.

3.2 Mounting Options
The R502 comes with three types of brackets for flexible installation:
- Flush Mount Bracket: For a recessed installation, providing a sleek, integrated look.
- Short Surface Mount Bracket: For surface mounting where minimal protrusion is desired.
- Long Surface Mount Bracket: For surface mounting, offering more space behind the unit if needed.

3.3 Wiring Connection
The R502 utilizes a lever-nut connector for simplified and secure wiring.
- Strip approximately 1/2 inch (12mm) of insulation from the ends of your RV's 12V DC power wires.
- Open the orange levers on the lever-nut connector.
- Insert the stripped red wire from the alarm into the positive (+) terminal of your RV's 12V DC power supply. Insert the stripped black wire from the alarm into the negative (-) or ground terminal.
- Close the orange levers to secure the wires. Ensure a firm connection.
Important: Ensure 12V to red (+) and ground to black (-) to prevent damage to the unit.

4. Operating Instructions
Once properly installed and powered, the Leakbee R502 will begin monitoring for CO and LP gas.
4.1 Initial Power-Up
Upon initial power connection, the alarm will perform a self-test. The digital display may show various numbers or symbols, and the indicators will cycle. After a brief warm-up period, the green POWER indicator light should illuminate, indicating normal operation.
4.2 Indicators and Display
The R502 features a digital LED display and indicator lights:
- Digital LED Display: Shows the concentration level of carbon monoxide (in PPM) or propane (in %LEL) when detected.
- CO Indicator: Illuminates when carbon monoxide is detected.
- LP Indicator: Illuminates when propane gas is detected.
- POWER Indicator (Green): Indicates the unit is receiving power and operating normally.

4.3 Alarm Conditions
The alarm provides both visual and audible warnings:
- Audible Alarm: Emits an 85-decibel warning sound.
- Visual Alarm: The digital display will show the detected gas level, and the corresponding CO or LP indicator will illuminate.
In the event of an alarm:
- Immediately open all windows and doors to ventilate the RV.
- Turn off all gas appliances and the main gas supply.
- Evacuate all occupants from the RV.
- Do not re-enter until the alarm has ceased and the area has been thoroughly ventilated.
- Identify and rectify the source of the leak. If unable to do so, seek professional assistance.
4.4 Test/Mute Button
Press the TEST/MUTE button to:
- Test the Alarm: A short press will initiate a self-test, activating the audible alarm and illuminating all indicators.
- Mute the Alarm: During an active alarm, a short press will temporarily silence the audible alarm for a few minutes. The visual indicators will remain active until the gas concentration drops to a safe level.
- Turn off Display: A long press (3 seconds) and release of the button can turn off the bright digital number display for nighttime use.
5. Maintenance
Regular maintenance ensures the continued reliability of your Leakbee R502 alarm.
5.1 Regular Testing

5.2 Cleaning
Clean the exterior of the alarm periodically with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure no dust or debris obstructs the sensor openings.
5.3 End-of-Life Indication and Replacement
The Leakbee R502 has a service life of 5 years (60 months) from its first power-on. When the unit reaches its end-of-life, the digital display will show an 'E'.
