3.1 Power-On and Normal Operation
After battery installation, the detector will perform a self-test. The power indicator light (usually green) will flash periodically, indicating normal operation. If any issues are detected during the self-test, refer to the Troubleshooting section.
3.2 Prova de l'alarma
It is crucial to test your CO detector weekly to ensure it is functioning correctly.
- Press and hold the 'TEST/RESET' button on the front of the detector for a few seconds.
- The alarm will sound a loud, distinct pattern, and the alarm indicator light (usually red) will flash.
- Release the button. The alarm will stop, and the detector will return to normal operation.

3.3 Alarma de monòxid de carboni
If the detector senses a dangerous level of CO, it will activate the alarm:
- The alarm will emit a loud, continuous sound pattern (e.g., 4 quick beeps, pause, 4 quick beeps).
- The alarm indicator light (red) will flash rapidly.
What to do if the alarm sounds:
- Immediately move to fresh air outdoors or open all doors and windows.
- Do a head count to check that all persons are accounted for.
- Do not re-enter the premises until it has been aired out and the CO source has been identified and corrected.
- Seek medical attention for anyone experiencing symptoms of CO poisoning (headache, nausea, dizziness).
- Contact the appropriate emergency services or a qualified technician to investigate the source of CO.

3.4 Silence/Reset Function
Pressing the 'TEST/RESET' button during an alarm will temporarily silence the alarm for a short period (e.g., 5-10 minutes). This function is useful for investigating the source of CO. If the CO level remains high, the alarm will reactivate.
4. Manteniment
4.1 Proves regulars
Test your CO detector weekly by pressing the 'TEST/RESET' button as described in Section 3.2.
4.2 Cleaning the Detector
Clean the detector regularly to prevent dust and debris from interfering with its operation. Use a soft, damp cloth to wipe the exterior. Do not use cleaning solvents or sprays directly on the detector.
4.3 Substitució de la bateria
The detector will emit a short chirp every 30-60 seconds and the low battery indicator light (usually amber) will flash when the batteries are low. Replace both AA batteries immediately following the instructions in Section 2.2.
4.4 Senyal de fi de vida útil
The FireAngel CO-9B has a typical lifespan of 7 years. When the detector reaches its end-of-life, it will emit a specific end-of-life signal (e.g., two chirps every 30 seconds). When this occurs, the detector must be replaced immediately.
