You should test your smoke alarms monthly by pressing the test button to ensure they are functioning correctly.

Regularly testing your smoke alarms is a critical part of home safety. Press the test button on each unit once a month to verify that the power, battery, and alarm mechanisms are all working. This simple action can confirm the device is operational and will alert you in case of a fire. If an alarm fails the test, it's important to address it immediately by replacing the battery or the unit itself.

This information provides general guidance on smoke alarm maintenance and testing.

When is it time to replace an old smoke alarm?

Myinfiniteinsights

Smoke alarms have a limited lifespan and need replacement approximately every 10 years from the date of manufacture. You can find the manufacture date on the back or side of the unit. Even if a smoke alarm appears to be working, its sensors degrade over time, making it less effective. If your smoke alarm is older than 10 years, or if it fails a monthly test after a battery change, it's time for a replacement to ensure continued protection.
