Wait, what?!?! Smoke alarms expire??? Yes, they do!
All smoke alarms wear out. You need to replace them every 10 years according to the manufacturer’s instructions. Check the back or the side of the smoke alarm to find the expiry/replacement date. If you purchase a new alarm, remember to write-in the date it was installed - there is usually a spot on the side of the alarm where you can fill in this information.
Test them monthly!
