You may have trouble hearing your doorbell due to a number of reasons including the size of your property, a defect in the doorbell's sound unit or a hearing impairment. As a result, installing a doorbell extender increases the range of your current doorbell's sound. Alternatively, some doorbells come with a volume adjuster, which makes the sound louder. You can troubleshoot it by checking the sound unit for a volume adjuster prior to modifying your current installation. To get a louder doorbell, you should first understand how your current installation works. For example, if your doorbell plays a melody or has a lighted push button, some extenders may not be compatible.
Go to a home improvement store and request a doorbell extender. The Home Depot, for example, carries extenders, which attach to your current installation to extend the doorbell's range. Ask a sales associate to show you different models and explain the features. Select a model that suits your needs based on ease of installation, chimes, compatibility and budget, for example.
Disconnect power from your existing doorbell chime. Generally, there will be two wires that you must pull away from the existing doorbell. Prior to disconnection, ensure that the power is off.
Remove the cover from your existing doorbell. Gently push or pull the cover to loosen and remove it. You may need a screwdriver to remove the housing.
Loosen the screws in the existing chime box. Make sure the screws and existing wires remain intact. Push the fork shaped wire connectors of the extender underneath the screws in your existing chime box.
Restore power to your existing doorbell chime.
Place the extender sound unit in a convenient location and push your doorbell to confirm the system works.
Purchase a new doorbell from a home improvement store. Alternatively, you can search online prior to completing the purchase to make an informed decision.
Disconnect power to the doorbell to ensure your safety.
Remove the screws from the button switch at your door. Tape the wires to the door jamb to ensure they don't slip into the wall opening. Reconnect the wires to the new button switch and screw the switch to the door jamb.
Remove the screws to your existing chime unit. Gently remove the cover and the wires. It may help to label them by writing information on a piece of masking tape. Place the tape on the corresponding wires to prevent them from slipping into the wall opening.
Insert the wires into the new chime unit. Thread the wires through the opening provided in the new unit.
Screw the new unit to the wall using the screws that came with the kit. Connect each wire to the proper terminal using the labels you created.
Attach the new chime unit cover. If necessary, insert and twist any screws into place.
While doorbells use low voltage, you should still disconnect power to ensure your safety during installation.
