How does the FA3322 alarm memory function work?

General

23 April 2026

If the FA3322 detects carbon monoxide while you are away, the 30-day memory stores the event. A red LED flashes twice every 40 seconds for up to 7 days to alert you that CO was present. The LCD display also shows the peak CO level recorded during the event. Press the test button to clear the memory indicator. See our guide to CO alarm memory for more information.
