When do I replace my alarms?
Oct 27, 2011
In accordance with the National Fire Protection Association (NFPA), Kidde recommends replacing smoke and heat alarms every ten years, and replacing carbon monoxide and combination alarms every seven to ten years (depending on your model) to benefit from the latest technology upgrades.
If you are unsure of your alarm’s age, look for the manufactured date on the back of the alarm. For more information on how to find a manufactured date, go to How to Find the Manufacture Date on an Alarm. You may also replace your alarm to avoid any danger.
For more information about your specific alarm, refer to your user’s manual.
