The Ring Doorbell Pro is designed for continuous operation. It streams video, detects motion, sends alerts, and supports features like pre-roll and advanced motion zones—all of which require steady power. A battery simply can’t keep up with that kind of demand without frequent recharging or replacement.
That’s why Ring made the Pro model a wired-only device. It draws power directly from your home’s electrical system through the same low-voltage wires that powered your old doorbell. This ensures reliable performance 24/7, even during heavy usage.
But here’s the catch: not all doorbell systems are created equal. If your existing transformer doesn’t supply the right voltage and amperage, your Ring Doorbell Pro might not work properly—or at all. That’s why understanding your power source is the first and most important step.
What You’ll Need to Power Ring Doorbell Pro
Before you begin, gather the following tools and materials:
- Ring Doorbell Pro (with included mounting bracket and screws)
- Ring Pro Power Kit (included with the doorbell)
- Compatible transformer (16–24V AC, 30–40VA)—check if your existing one meets this
- Screwdriver (Phillips and flathead)
- Wire strippers
- Voltage tester or multimeter
- Electrical tape
- Ladder (if your doorbell is high up)
- Safety gloves and goggles (optional but recommended)
Most of these items come with the Ring Doorbell Pro or are commonly found in a home toolkit. The most critical component—the transformer—may need to be upgraded if your current one is too weak.
Step 1: Check Your Existing Doorbell Setup
Before installing the Ring Doorbell Pro, you need to assess your current doorbell system. This will help you determine whether your existing wiring and transformer can support the new device.
Locate Your Doorbell Transformer
The transformer is a small box that steps down your home’s 120V AC power to a lower voltage (usually 16–24V) suitable for doorbells. It’s typically found in one of these locations:
- Inside the electrical panel (breaker box)
- In the basement or crawlspace
- Behind the existing doorbell chime
- In the attic
Look for a small metal or plastic box with wires coming out of it and a label indicating voltage (e.g., “16V” or “24V”). If you can’t find it, check behind the chime unit inside your home.
Test the Voltage
Once you’ve located the transformer, use a multimeter to test the output voltage. Here’s how:
- Set your multimeter to measure AC voltage (V~).
- Touch the red probe to the “Front” terminal and the black probe to the “Trans” terminal on the chime unit (or directly to the transformer wires if accessible).
- Read the voltage on the display.
The Ring Doorbell Pro requires **16 to 24 volts AC** and **30 to 40 volt-amperes (VA)**. If your transformer outputs less than 16V or less than 30VA, it won’t provide enough power. You’ll need to upgrade it.
Tip: If you’re unsure about using a multimeter, consider hiring an electrician. Incorrect voltage can damage your doorbell or cause it to malfunction.
Check the Wiring
Inspect the wires running from the transformer to your doorbell location. They should be intact, with no fraying or corrosion. If the wires are damaged or too short, you may need to run new ones.
Also, confirm that your doorbell location has two wires (typically labeled “Front” and “Trans”) connected to the existing button. The Ring Doorbell Pro needs both wires to function.
Step 2: Upgrade Your Transformer (If Needed)
If your current transformer doesn’t meet the 16–24V, 30–40VA requirement, you’ll need to replace it. This is a common step, especially in older homes.
Choose the Right Transformer
Look for a doorbell transformer that meets these specs:
- Output: 16–24V AC
- Power: 30–40VA
- Compatible with standard doorbell systems
Popular brands include Nutone, Heath Zenith, and Ring’s own recommended models. You can find them at hardware stores or online retailers like Amazon or Home Depot.
Install the New Transformer
Warning: Always turn off power at the breaker before working with electrical components.
- Turn off the circuit breaker that controls the doorbell.
- Remove the old transformer. It’s usually mounted near the breaker panel or inside a junction box.
- Disconnect the wires (note which wire goes where).
- Connect the new transformer using wire nuts or terminal screws.
- Mount the transformer securely and restore power.
- Test the voltage again to confirm it’s within range.
If you’re not comfortable working inside your electrical panel, hire a licensed electrician. This ensures safety and compliance with local codes.
Step 3: Install the Ring Pro Power Kit
The Ring Pro Power Kit is a small but essential component that helps regulate power and protect your doorbell from voltage spikes. It’s included with your Ring Doorbell Pro and must be installed for the device to work properly.
What’s in the Power Kit?
The kit includes:
- A small inline module with two wires
- Wire connectors
- Instructions
This module is installed in line with your doorbell wiring, typically at the chime unit inside your home.
How to Install the Power Kit
Follow these steps:
- Turn off power at the breaker.
- Remove the cover of your existing doorbell chime.
- Locate the two wires connected to the “Front” and “Trans” terminals.
- Disconnect these wires.
- Connect one wire from the Power Kit to the “Front” terminal on the chime.
- Connect the other wire from the Power Kit to the “Front” wire that goes to the doorbell.
- Connect the “Trans” wire from the chime to the other terminal on the Power Kit.
- Use wire nuts to secure all connections.
- Tuck the Power Kit module into the chime box and reattach the cover.
- Restore power and test the system.
The Power Kit acts as a buffer, ensuring the Ring Doorbell Pro receives consistent power without overloading the chime. Without it, your doorbell may not function or could damage your chime.
Step 4: Mount the Ring Doorbell Pro
Now that your power source is ready, it’s time to install the doorbell itself.
Remove the Old Doorbell
If you have an existing doorbell, carefully remove it:
- Unscrew the old button from the wall.
- Disconnect the two wires.
- Pull the wires through the wall slightly so they’re accessible.
Prepare the Wires
Strip about 1/4 inch of insulation from the ends of the two wires using wire strippers. This ensures a solid connection.
Attach the Mounting Bracket
The Ring Doorbell Pro comes with a mounting bracket. Use the included screws to attach it to the wall. Make sure it’s level and secure.
Connect the Wires
Thread the two wires through the bracket and connect them to the terminals on the back of the Ring Doorbell Pro:
- One wire to the “Front” terminal
- One wire to the “Trans” terminal
It doesn’t matter which wire goes where—the Ring Doorbell Pro is not polarity-sensitive. Just make sure both are securely fastened.
Attach the Doorbell
Slide the Ring Doorbell Pro onto the mounting bracket until it clicks into place. Use the included security screw to prevent tampering.
Step 5: Power On and Test
Once everything is connected, it’s time to power up and test your system.
