Adding a doorbell chime to your home is a great way to be alerted when someone is at the door. Installing a doorbell chime system is relatively easy, but understanding the wiring diagram can be a bit more complicated for those without electrical knowledge. To help make the installation process easier, we’ve broken down the steps into a simple, easy-to-follow guide.

Step 1: Prepare the Power Supply

Before you start any wiring, you will need to prepare the power source. This can be either done by connecting to a dedicated transformer or by tapping into an existing doorbell circuit. If you are connecting to an existing circuit, you may need to add a power supply. The power supply should be a 16-volt AC transformer. Make sure the power source is properly grounded.

Step 2: Connect the Wires

Once the power source is ready, it’s time to start the wiring. Most doorbell systems come with a wiring diagram that shows the specific connections that need to be made. First, connect the doorbell button wires to the power source. Once that is done, connect the chime to the transformer. Make sure the wires are securely connected and the connection is insulated.

Step 3: Test the System

Once the wiring is complete, it’s time to test the system. Flip the power switch to the “on” position and press the doorbell button. If everything is connected correctly, the chime should sound. If the chime doesn’t sound, double-check the wiring diagram and make sure all the connections are secure.


Installing a doorbell chime system is a relatively easy task. By understanding the wiring diagram and following the steps outlined above, you should be able to install the system without any issues. Once the system is installed, all that’s left to do is enjoy the convenience of having a doorbell chime in your home.
