End-of-Life Warnings - Required For Your Safety
In 2009, Underwriters Laboratories (UL), began requiring an end-of-life warning to alert homeowners when their carbon monoxide alarm has reached the end of its useful life. As an industry leader committed to safety, Kidde has included this feature in all of its carbon monoxide alarms since 2001. Kidde carbon monoxide alarms have a proven life of seven to ten years, depending on the model type.
As of 2013, ALL Kidde carbon monoxide alarms have a 10-year life, with the following exceptions: Model KN-COEG-3 (900-0113), KN-COPE-I (900-0232) and KN-COPP-3 (900-0099). If your CO alarm was manufactured before 2013, it has a seven-year life.
Carbon monoxide alarms do not detect the presence of carbon monoxide when in end-of-life mode.
Replace your carbon monoxide alarms before the end-of-life warning. If you think your carbon monoxide alarm is nearing its end-of-life, replace it today.
*Models equipped with end-of-life hush feature can be temporarily silenced for 3-day intervals for a total of 30 days.
Is your carbon monoxide alarm beeping? To determine if your alarm is at the end of its life, refer to the following:
End-of-Life warning will occur every 30 seconds
If the alarm has a digital display, it displays the ERR or END error code.
Replacing the battery WON'T STOP the beep
The beep will ONLY STOP when the alarm is out of power
Find out if your beeping alarm is in end of life:
Important! Carbon monoxide alarms do not detect the presence of carbon monoxide when in end-of-life mode. Immediately replace your CO or Smoke/CO combination alarm with a new one.
