Description
Press release from the Seattle Fire Department :
William Mace
January 4, 2022
Every year, the Seattle Fire Department receives 9-1-1 calls from concerned residents because of chirping carbon monoxide (CO) alarms. 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. Most likely, it's an indication that your CO alarm has reached its end of life and should be replaced.
CO alarm life span
CO alarms have a life expectancy of around seven years. All CO alarms produced after August 1, 2009, have an end-of-life warning notification that alerts the resident that the alarm should be replaced. The CO alarm will beep every 30 seconds or display ERR or END.
If a CO alarm is at its end-of-life, replacing the battery will not stop the beep. Some CO alarms have a feature that will silence the signal for 30 days, but this will not solve the issue as the CO alarm will continue to beep after the 30 day period ends.

Replace your CO alarm if it was installed before 2015 or if it is beeping every 30 seconds.
