How to Stop My Smoke Alarm From Beeping After I Remove the Battery

Smoke alarms are an early-warning system designed to alert you to the possible presence of a house fire. Replace the batteries every six months, and check the units once a month to ensure proper operation. A beeping alarm means that there is a problem with the unit, which typically is a dead or dying battery. The battery is necessary for proper operation. Removing the battery does not stop the beeping on most devices. Stopping the beeping requires discharging the system.

A smoke alarm system is typically linked by electric cables joining all the alarms.

Step 1

Disconnect each smoke alarm from the wall or ceiling mounts and disconnect the wires.

Step 2

Remove the batteries from each unit and press down the "Test" button until the beeping stops. Pressing down the button discharges residual electricity in the unit.

Step 3

Install new batteries into the units.

Step 4

Reconnect any electrical wires and remount the units on the wall or ceiling. A green light will appear on the unit indicating that it is functioning properly. Replace the unit if the beeping continues.
