You install a Ring Doorbell Pro by connecting it to your existing doorbell wiring, then wiring the included Pro Power Kit across your chime’s terminals so the mechanical or digital chime inside your house keeps working. Skip that second step and the doorbell will power up fine, but your indoor chime will go silent, which is the single most common regret after this upgrade.
Most Ring Doorbell Pro guides only cover getting the doorbell itself to light up. If you already paid for a chime and want to keep hearing it, the Pro Power Kit is the part you cannot skip.
By the end of this guide, you will know where the kit goes, what voltage your transformer needs, and how to finish setup in the Ring app without an electrician.
Why the Ring Doorbell Pro Needs Hardwiring
Unlike battery-only Ring models, the Ring Doorbell Pro draws continuous power from your home’s doorbell transformer. It needs 16 to 24 VAC to run its always-on video feed and motion sensors.
Most homes built with a traditional doorbell already have this transformer wired to a chime box. That existing circuit is what you will tap into, not a new electrical line.
What the Pro Power Kit Actually Does
The Pro Power Kit is a small adapter that sits inline between your transformer and your existing chime, not at the doorbell itself. It splits the incoming power so your chime keeps ringing while the doorbell also gets a steady, regulated supply.
Without it, digital chimes can buzz, flicker, or stop responding once the doorbell starts pulling power from the same wires. Mechanical chimes sometimes still work, but Ring recommends installing the kit regardless, since it protects both devices from voltage drops.
Step-by-Step Ring Doorbell Pro Installation
Shut off power to the doorbell circuit at your breaker panel. Test the old doorbell button to confirm power is actually off before touching any wires.
Remove your old doorbell and disconnect its two wires. Connect those same wires to the terminals on the Ring Doorbell Pro, matching the mounting bracket to your door frame.
Open your indoor chime box next. This is where the Pro Power Kit gets installed, wired across the chime’s terminals rather than replacing them.
Mount the doorbell, restore power at the breaker, and confirm the light ring turns on. Working with brick or masonry instead of siding changes the drilling process slightly, which this Ring doorbell installation on brick guide covers.
Setting Up the Ring Doorbell Pro in the Ring App
Open the Ring app and select “Set Up a Device,” then choose the Doorbell Pro from the device list. The app walks you through connecting to your home Wi-Fi and naming the device.
Once connected, test the chime by pressing the button and listening for both the app notification and your physical chime. If your home has no existing wiring at all, a battery-powered alternative might suit you better, and this wireless Ring doorbell installation guide walks through that setup path instead.
If you are unsure whether this project is worth tackling yourself versus calling in help, this breakdown of what to handle yourself versus hire out for smart home projects can help you decide before you start pulling wires.
FAQ
Does the Ring Doorbell Pro work with any doorbell chime?
It works with most mechanical and digital chimes as long as your transformer supplies 16 to 24 VAC. Older transformers below that range may need replacing first.
Can I skip the Pro Power Kit?
You can, but your indoor chime is likely to stop ringing or behave erratically, especially with digital chimes. Installing the kit takes a few extra minutes and avoids that problem entirely.
Do I need an electrician to install a Ring Doorbell Pro?
Most homeowners can complete this installation themselves using existing doorbell wiring and basic tools. If your transformer voltage is wrong or your wiring is damaged, an electrician should handle that part first.
