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.

What should I do if my smoke alarm fails the monthly test?

If your smoke alarm fails the monthly test, do not ignore it. First, try replacing the battery with a fresh one, ensuring it's installed correctly. If the alarm still does not sound after a battery change, the unit itself may be faulty or expired. Most smoke alarms have a lifespan of about 10 years; check the manufacture date on the back of the unit. If it's old or the test continues to fail, you must replace the entire smoke alarm unit to ensure your home's safety.
