My Smoke Detector Stopped Working

Battery

• Smoke alarms mainly use 9-volt, AA, or AAA batteries. If the smoke detector is not working, the batteries are likely running low. Most detectors will beep continuously as a warning to replace the batteries.

Testing

• Take down your smoke detector and replace the batteries. Press the "Test" or "Reset" button on your device. Your smoke detector should sound for a few seconds. Test your smoke detector at least once a month.

Cleaning and Maintenance

• Take down your smoke detector. Vacuum in and around it to remove dirt, cobwebs, and insects.
