Step 1: Turn Off the Power
Safety first! Before touching any wires, you must turn off the power to your existing doorbell circuit.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “Doorbell,” “Chime,” or something similar. If it’s not labeled, you may need to test breakers one by one.
Turn Off the Breaker
Switch the correct breaker to the “OFF” position. To double-check, go to your existing doorbell and press the button. If the chime doesn’t sound, the power is off. You can also use a non-contact voltage tester near the doorbell wires to confirm no electricity is flowing.
Pro Tip: Place a piece of tape over the breaker switch with a note like “DO NOT TURN ON – WORKING ON DOORBELL.” This prevents someone else from accidentally restoring power while you’re working.
Step 2: Check Your Transformer Voltage
The Ring Doorbell Pro requires a transformer that outputs between 16 and 24 volts AC (alternating current) and at least 30–40VA (volt-amperes). Most older doorbells use 8–16V transformers, which are insufficient and can cause the Pro to malfunction or not work at all.
Locate the Transformer
The transformer is usually found in one of these places:
– Inside the doorbell chime box (inside your home)
– In the basement near the furnace
– In the attic
– Near the electrical panel
It looks like a small metal box with wires coming out and often has “16V” or “24V” printed on it.
Test the Voltage
Use a multimeter to check the voltage:
1. Set the multimeter to AC voltage (usually marked as “V~”).
2. Touch the red probe to the “Front” or “Trans” terminal and the black probe to the “Trans” or “Common” terminal on the chime.
3. Read the voltage on the display.
If the reading is below 16V, your transformer is too weak. You’ll need to replace it with a 16–24V, 30–40VA transformer. If it’s within range, you’re good to go!
Note: If you’re unsure about replacing the transformer, hire a licensed electrician. Incorrect wiring can damage your doorbell or create a fire hazard.
Step 3: Remove the Old Doorbell
Now that the power is off and the voltage is confirmed, it’s time to remove your existing doorbell.
Unscrew the Faceplate
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the doorbell away from the wall. You’ll see two wires connected to the back—usually labeled “Front” and “Trans” or just two bare ends.
Disconnect the Wires
Loosen the screws holding the wires and carefully remove them. Don’t let the wires fall back into the wall. Use electrical tape to wrap the ends temporarily so they don’t touch each other or the wall.
Inspect the Wiring
Check the condition of the wires. If they’re frayed, corroded, or too short, you may need to extend them. Use wire strippers to expose about 1/2 inch of fresh copper if needed.
Step 4: Install the Pro Power Kit
The Pro Power Kit is a small device that connects to your existing doorbell chime inside your home. It ensures the Ring Doorbell Pro gets consistent power and prevents the chime from buzzing or not working.
Open the Chime Box
Go inside your home and locate the doorbell chime (usually near the front door). Remove the cover to access the wiring.
Identify the Wires
You should see two wires connected to the “Front” and “Trans” terminals. These are the same wires that were connected to your old doorbell.
Connect the Pro Power Kit
1. Disconnect the two wires from the chime.
2. Connect one wire to the “Front” terminal on the Pro Power Kit.
3. Connect the other wire to the “Trans” terminal on the Pro Power Kit.
4. Use the included wire nuts to secure the connections.
5. Wrap each connection with electrical tape for extra safety.
The Pro Power Kit has a small LED light. When powered correctly, it will glow green. If it doesn’t light up, double-check your connections and transformer voltage.
Reassemble the Chime
Once the Pro Power Kit is installed, put the chime cover back on. Make sure no wires are pinched.
Step 5: Mount the Ring Doorbell Pro
Now it’s time to install the doorbell itself.
Attach the Mounting Bracket
1. Hold the mounting bracket against the wall where you want the doorbell. Use a level to make sure it’s straight.
2. Mark the screw holes with a pencil.
3. Drill pilot holes if needed (especially for brick or concrete).
4. Secure the bracket with the provided screws.
Connect the Wires
1. Strip about 1/2 inch of insulation from the two doorbell wires.
2. Insert one wire into the “Front” terminal on the back of the doorbell.
3. Insert the other wire into the “Trans” terminal.
4. Tighten the screws to secure the wires. Make sure they’re snug—loose connections can cause power issues.
Attach the Doorbell
Slide the Ring Doorbell Pro onto the mounting bracket until it clicks into place. Give it a gentle tug to ensure it’s secure.
Step 6: Restore Power and Test
You’re almost done! Now it’s time to turn the power back on and test the system.
Turn On the Breaker
Go back to the electrical panel and switch the breaker back to “ON.”
Check the Doorbell
Within a few seconds, the Ring Doorbell Pro should power on. You’ll see a light ring around the button—usually white or blue—indicating it’s receiving power.
Test the Chime
Press the doorbell button. The chime inside should sound. If it doesn’t, check the Pro Power Kit connections and ensure the transformer is providing enough voltage.
Step 7: Set Up the Ring App
Now that the hardware is installed, it’s time to connect your doorbell to Wi-Fi and customize settings.
Open the Ring App
Launch the Ring app on your smartphone. If you don’t have an account, create one.
Add a New Device
Tap the “+” icon and select “Set up a device.” Choose “Doorbells” and then “Ring Video Doorbell Pro.”
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the doorbell or inside the app.
Connect to Wi-Fi
Follow the prompts to connect the doorbell to your 2.4GHz Wi-Fi network. (Note: The Ring Doorbell Pro does not support 5GHz networks.)
