Beeping Problems With Smoke Alarms

Replace the Battery

• Smoke alarms will beep or chirp when their batteries need to be replaced. You can replace the battery by removing the outer cover and the old battery. Ensure the new battery is securely attached to the terminal. You need to dispose of the old batteries responsibly. Test the alarm to ensure that it is in good working order.

Battery Tab Obstruction

• If your alarm continues to beep after the battery has been replaced, open the outer cover and see if the battery tab was removed. Verify that the terminal is not obstructed and that the battery is correctly attached. If the beeping persists, call a professional.

Obstructions

• Smoke alarms collect dust, dead insects and cobwebs. Over time, these may obstruct the sensors or battery terminal. If your smoke alarm beeps, remove the outer cover and use a vacuum to remove built-up detritus. Include this activity as part of your maintenance regimen. Smoke alarms should be cleaned every six months.

Power Interruption

• Hardwired smoke alarms will beep or chirp when the power has been interrupted. Domestic power outages or surges can affect the alarm. Simply wait for the power to turn back on. If the beeping persists, check the backup battery.
