When do I need to replace my smoke alarms?
Smoke alarms should function properly for ten years. Like most electrical appliances, smoke alarms wear out. After 10 years your smoke alarm will have been working for over 87,000 continuous hours. You may want to write the purchase date with a marker on the back of your smoke alarm. That way you will know when it should be replaced.
