To determine if a CO non-digital alarm has reached its end of life, perform the following:

  1. When the CO alarm emits a quick Beep every 30 seconds and the red LED  flashes, you may need to change the batteries.
  2. Replace the batteries in the alarm.change-battery
  3. 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.
