How do I determine if my carbon monoxide non-digital alarm has reached its End of Life?
Nov 1, 2011
To determine if a CO non-digital alarm has reached its end of life, perform the following:
When the CO alarm emits a quick Beep every 30 seconds and the red LED flashes, you may need to change the batteries.
Replace the batteries in the alarm.
If the alarm continues to emits a quick Beep every 30 seconds and the red LED flashes, the alarm has reached the end-of-life.
