Steps For Installing a Doorbell

If you want to install a new doorbell, start by gathering your supplies. You will need a chime, a button, and a transformer. These components can either be purchased separately or in a prepackaged set. When you are ready, you will also need a multimeter, a screwdriver, and a non-contact tester.

Confirm Your House Is Wired for a Doorbell

Before you get started, you must find out if your house is already wired. If you do not have wires for a doorbell behind your walls, you will have to decide if you want to invest the time and money to install the components of a doorbell. Enlist the help of a skilled electrician to locate the nearby junction box, add a transformer, and wire through the walls.

Test the Doorbell Transformer

You are ready for the next step once you know your home is wired for a doorbell. Locate your doorbell transformer, a small device attached to an electrical box commonly found in closets or basements.

Set your multimeter to a volts AC (VAC) setting and set the probes to the attached screws. The transformer is functioning if it reads 8V, 16V, or 24V. If your doorbell transformer reads accurately, move on to the next step.

Shut Off the Electricity to the Doorbell at the Breaker Box

If your home is wired and your transformer is functioning, you are ready to install a new doorbell. Head to the breaker box or electrical panel and ensure all electricity to the doorbell is off.

While the transformer reduces the electric voltage to the doorbell, it is not enough to prevent electric shock if you try to remove the doorbell without following this step.

Disassemble the Existing Doorbell

With the electricity safely shut off, head back outside to your doorbell. Take off the button and carefully disconnect the wires. Avoid cutting them, as they are typically short to begin with. Take off the cover from the doorbell chime and carefully detach the wires from it. Disconnect the chime by removing the screws.

Replace the Doorbell Transformer

The next step to wiring a new doorbell is to determine if your transformer needs to be replaced. Do you need to install a new doorbell transformer? Check your new chime to determine what voltage it requires.

Remove the old transformer by taking off the cover plate. Next, double-check the flow of power by using a non-contact tester before you detach the device itself.

Once you have ensured it’s safe, detach the old transformer from the plate. Use the existing entry and locknut to wire your new transformer into place. Twist the wires together and use wire nuts to cap them safely.

Connect the chime and button wires to the new transformer before you replace the cover plate. Before you install your new doorbell, briefly switch the electricity back on and confirm the voltage of the transformer with your multimeter.

Connect the Wires to the New Doorbell

Now it’s time to put your new chime on the wall. Connect the transformer wire to the transformer and the button wire to the chime. If multiple doorbells exist, double-check you have attached them correctly to the front or back positions.

Attach your new doorbell to the wall by connecting the wires for the transformer and the chime. Securely screw the new doorbell into place.

Turn the Circuit Breaker On and Test the Doorbell

Head back to your breaker box and turn on the electricity. Test out your new doorbell and listen for the chime. If the doorbell is not working, ensure your wiring reaches the correct location. If they are positioned correctly, you may have faulty wiring or a deeper issue with the mechanism.

Types of Doorbells for Homes

Homeowners have various doorbell options depending on their needs, preferences, lifestyles, and the style of homes. Do some research to see if a wired, wireless, or smart doorbell is right for you.

Wired Doorbells

If you have a wired doorbell, it was likely installed when the house was built. While labor-intensive to put in, they do not require upkeep as they connect to the electrical system. Wired doorbells last about ten years and are easy to replace.

Wireless Doorbells

If your home does not have the correct wiring for a doorbell, going wireless provides you with an affordable option. Attach the doorbell where you want it, then ensure the transmitter is close by. Depending on the type, it will need recharging or battery replacement.

Smart Doorbells

Smart doorbells have become an increasingly popular option for homeowners invested in greater security. A smart doorbell connects through WiFi to an app on your device, allowing you to monitor visitors through a camera or speakers.

How Does a Doorbell Work?

A doorbell functions when the button is pressed. This triggers the chime, alerting you to a visitor’s arrival.

Inside the doorbell’s operations, the transformer serves a critical function. As the electrical voltage in your house is much higher than the doorbell requires, the transformer reduces the voltage sent through the wires.

Doorbell Wiring

Wired doorbells have a simple system. The button is wired to the chime, which is then wired to the transformer. Three wires connect the transformer to the rest of the electrical system and are identified by color. Typically, the neutral wire is white, the ground wire is green, and the live wire is black.
