4. Setup and Installation
4.1 Choosing a Location
Install the alarm in a location that is at least 4 inches (10 cm) but not more than 20 inches (50 cm) above the ground. It should be placed near sleeping areas and where propane and carbon monoxide sources are present, such as near the kitchen or heating appliances. Avoid placing it directly next to windows, doors, or vents where air currents might affect sensor readings.

4.2 Wiring Instructions
The alarm operates on 12V DC power. Connect the RED wire to the positive (+) 12V DC power source and the BLACK wire to the negative (-) or ground. Ensure connections are secure and insulated.
Video: This video demonstrates how to properly connect the 12V DC power wires to the alarm using wire connectors.
4.3 Mounting
You can mount the alarm using either the provided 3M adhesive strips or screws. For screw mounting, use the included template to mark drill points. Ensure the mounting surface is clean and dry before applying adhesive or screws.
5. Operating Your Detector
5.1 Initial Power-Up
Upon initial power-up, the detector will undergo a 180-second countdown for pre-heating and calibration. During this time, the digital display will show a countdown, and the green LED indicator will flash. Once the countdown reaches zero, the display will show '0' for both CO (PPM) and LP (LEL%), and the green LED will remain solid, indicating normal operation.
5.2 Performing a Self-Test
It is recommended to perform a self-test monthly or weekly to ensure the alarm is functioning correctly. To perform a self-test:
- Press and hold the 'Test' button on the front of the alarm.
- The display will show '888' and the alarm will sound, indicating the test is active.
- Release the 'Test' button. The alarm will return to normal operation after the test sequence.
Video: This video demonstrates the simple process of performing a self-test on the detector, showing the '888' display and alarm sound.
5.3 Alarm Indications
The detector provides distinct alarms and visual cues for CO and LP gas detection:
- CO Alarm: Sounds a loud 85dB alarm when CO levels reach 150 PPM. The red CO LED will flash, and the digital display will show the CO concentration.
- LP Alarm: Sounds a loud 85dB alarm when LP gas levels reach 5% LEL. The red LP LED will flash, and the digital display will show the LP concentration.
- Mute Function: Press the 'Mute' button to temporarily silence the alarm for a short period. The alarm will reactivate if gas levels remain high.
