How does the FA6812-EUX10 alarm memory function work?

General

23 April 2026

If the FA6812-EUX10 detects carbon monoxide while you are away, the memory function stores the event. When you return, the red LED will flash twice every 40 seconds for up to 7 days to alert you that CO was present. Press the test button to clear the memory indicator. See our guide to CO alarm memory for more information.
