To determine if your carbon monoxide non-digital alarm has reached its end of life, refer to 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.
When an alarm has reached the end of its life, it needs to be replaced to continue protecting your home.
