How often should our smoke detectors be changed?

Typical smoke alarms last about eight-to-ten years, after which they should be replaced. Like most electrical devices, smoke alarms wear out. You may want to write the purchase date with a marker on the inside of your unit. That way, you’ll know when to replace it. We also recommend that smoke detector batteries are changed annually.
