How to Install Ring Doorbell 3 with Existing Doorbells?

If you have an existing doorbell, you can still add the Ring Video Doorbell 3 to your door. Installing your Ring Video Doorbell 3 with an existing doorbell is a simple process. Just follow this step-by-step guide.

Make sure to set up your Ring Video Doorbell 3 in your Ring app before mounting it in your home.

Step One: Charge the Included Battery

Fully charge the battery by connecting it to a USB power source using the supplied orange cable. When only one of the two LEDs on the battery is lit, the battery is fully charged. Insert the battery into the bottom of your Ring Doorbell 3 until it clicks into place.

If the device is not fully charged before use, you may see an incorrect battery discharge/report when setting up your Ring Video Doorbell 3. Fully charge the battery before setting up your device.

Step two: Remove your existing doorbell 

If you are replacing an existing doorbell, turn off the power to your doorbell system at the circuit breaker. Then remove the doorbell button from the wall and disconnect the wires. When connecting your Ring Doorbell 3 to an existing doorbell, a transformer with a voltage of 8-24 VAC, 40 VA max, 50/60 Hz is required.

DC transformers and most intercoms are not supported.

Look Here! Risk of electric shock. Disconnect power to the installation area at your circuit breaker or fuse box before beginning installation. Always use caution when handling electrical wiring.

Installation by a qualified electrician may be required in your area. Consult your local laws and building codes before doing any electrical work; permits plus professional installation may be required by law.

Step Three: Align Your Ring Video Doorbell 3

To properly align your Ring Video Doorbell 3, Snap the level (included in the box) into the small hole on the front of the Ring Doorbell 3, below the camera. Place the Ring Doorbell 3 next to your door about 48 inches off the floor.
Level the appliance using the spirit level tool. Mark the mounting hole positions with a pencil.

Note: The included adapter plate can be used to properly align the device if you are replacing an original Ring Video Doorbell.

Step Four (optional): Drill the mounting holes (for brick, concrete, or stucco mounting only)

Use the included drill bit in a power drill to drill holes in the positions you marked. Insert the supplied plastic plugs into the holes. You may need to use a hammer to get the anchors in. If you are mounting to wood or vinyl siding, you can skip this step.

Step five (optional): Attach the wire extensions

If you are having trouble connecting the wires coming out of the wall to the back of your Ring Doorbell 3, use the supplied wire extensions and wire nuts.

Step Six: Connect the Wires

Connect the wires coming out of your wall to the screws on the unit. Any wire can be connected to either screw. The order doesn’t matter. If the wiring is correct, you will see a solid white light on the front of the unit.

Step Seven: Place your Ring Video Doorbell 3 over the holes

Remember to remove the level from the front of the unit.

Step Eight: Screw on the Ring Doorbell 3

Feed all the wires (and the wire nuts if you used them) into your wall and mount your Ring Doorbell 3 to the wall. Be sure to use all four screws provided.

Step Nine: Install the Faceplate

Place one of the included faceplates on your Ring Doorbell by sliding it into the top and clicking into place.

Step Ten: Install the Security Screw

Use one of the supplied security screws and the star-shaped end of the screwdriver bit to secure the faceplate. Be sure to use the security screws to secure the faceplate and not the wood screw which could damage the battery.
