4. Operating Instructions
Self-Test and Indicators:
Upon activation, the detector performs a self-test. The LCD screen will show a countdown, and the LED indicators will flash. Once the self-test is complete, the detector enters normal operating mode.
- Normal Operation: The green LED flashes periodically (e.g., every 40 seconds) to indicate proper functioning.
- Carbon Monoxide Detection: The red LED flashes, and the alarm sounds. The LCD will display the CO concentration in PPM.
- Smoke Detection: The blue LED flashes, and the alarm sounds.
- Low Battery Warning: The yellow LED flashes, and a chirp sound indicates that the battery needs replacement.
Test Button Functionality:
Press the test button on the side of the detector to manually check its functionality. The alarm will sound, and the LED indicators will activate. This confirms the sensors and alarm are working correctly.
In case of a false alarm, press the test button again to activate silent mode. The flashing LED will indicate silent mode for approximately 10 seconds before returning to normal operation.
5. Maintenance
Regular maintenance ensures the optimal performance and longevity of your detector.
- Monthly Testing: Press the test button once a month to ensure the alarm is functioning.
- Cleaning: Gently vacuum the detector's cover and vents with a soft brush attachment at least once a year to remove dust and debris. Do not use cleaning solvents or spray directly onto the unit.
- Battery Replacement: The built-in 10-year lithium battery is designed to last the lifespan of the unit. If a low battery warning occurs prematurely, contact customer support.
6. Troubleshooting
If your detector is not functioning as expected, refer to the following common issues:
| Problem | Possible Cause | Solution |
