Understand the Difference between Carbon Monoxide Detector Beeping and Chirping

Once again, I would to remind you that you should be able to distinguish between beeping and chirping. First Alert’s carbon monoxide detector chirping whenever it is malfunction or has reached its end of life.

If the detector is malfunction, then the following indications appear:

Horn sounds 3 chirps every minute.
Power/alarm light flashes 3 times approximately once a minute.

If the detector has reached its end of life:

Horn sounds 5 chirps every minute.
Power/alarm light flashes 5 times approximately once a minute.

If you feel hard to distinguish between those two indications, do not worry. Because every time you find both indications, you should replace the unit immediately. Yes, you should. This tells you that your carbon monoxide detector has failed to work. You need a new one.
