First alert gas and carbon monoxide detector manual
1 Beep Every Minute: Low Battery. It is time to replace the batteries in your carbon monoxide detector. 5 Beeps Every Minute: End of Life. This type of chirp indicates it is time to replace your carbon monoxide alarm.
You can test this CO Alarm by pressing the Test button on the Alarm cover until alarm chirps. The alarm horn will sound: 4 beeps, a pause, then 4 beeps. The alarm sequence should last 5-6 seconds. If the unit does not alarm, make sure it has been activated correctly, and test again.
On First Alert® carbon monoxide alarms, the red light flashes to show the Carbon Monoxide Alarm is properly receiving battery power. If you do not see the red light flashing, change the batteries in the alarm immediately.
While it's important to call 9-1-1 if your CO alarm is sounding continuously without stopping, a CO alarm that chirps every 30 seconds is not an emergency. It probably means your CO alarm has reached its end of life and should be replaced. CO alarms have a life expectancy of around seven years.
