Pro Tip: Prepare Your Workspace
Clear the area around your doorbell. Turn off the power at the breaker box and use a voltage tester to confirm no electricity is flowing to the wires. This prevents accidental shocks.
Step 3: Turn Off Power at the Breaker
Safety is paramount when working with electrical wiring. Never skip this step.
Locate Your Breaker Box
Find your home’s main electrical panel. It’s usually in the basement, garage, or utility closet.
Identify the Doorbell Circuit
Look for a breaker labeled “Doorbell,” “Chime,” or “Low Voltage.” If there’s no label, turn off breakers one by one and test the doorbell button to see which one cuts power.
Turn Off the Breaker
Switch the correct breaker to the “OFF” position. Use a non-contact voltage tester on the doorbell wires to confirm no power is present.
Label the Breaker (Optional)
Use a label maker or tape to mark the breaker for future reference. This helps avoid confusion during maintenance.
Step 4: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, you’ll need to remove it first.
Unscrew the Faceplate
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the device away from the wall.
Disconnect the Wires
You’ll see two wires connected to the back of the old doorbell. Loosen the screws or release the clips holding them. Carefully pull the wires free.
Secure the Wires
Use electrical tape to wrap the exposed ends of the wires. This prevents them from touching each other or the wall, which could cause a short circuit.
Remove the Mounting Bracket
Unscrew and remove the old mounting plate. You may need to patch holes in the wall if you’re installing the Ring bracket in a new location.
Step 5: Check Your Doorbell Transformer
The transformer converts your home’s high-voltage electricity (120V) to low-voltage AC power (8–24V) for the doorbell. Your Ring doorbell needs a compatible transformer to function properly.
What Is a Doorbell Transformer?
A transformer is a small device usually located near your breaker box, furnace, or attic. It reduces voltage to a safe level for doorbells and chimes.
How to Find Your Transformer
1. Turn off power at the breaker.
2. Trace the doorbell wires from the wall back to their source.
3. Look for a small metal box with wires connected—this is the transformer.
Check Voltage and Power Rating
Use a multimeter to test the transformer output:
1. Set the multimeter to AC voltage (V~).
2. Touch the probes to the two transformer wires.
3. A reading between 8V and 24V AC is acceptable.
4. The transformer should also be rated at least 10VA (volt-amperes).
What If Your Transformer Is Incompatible?
If your transformer is below 8V or under 10VA, it won’t power the Ring doorbell reliably. You’ll need to replace it with a compatible one, such as the Ring Transformer (sold separately).
Installing a New Transformer
1. Turn off power at the breaker.
2. Disconnect the old transformer wires.
3. Connect the new transformer to the same terminals.
4. Mount it securely and restore power.
5. Test the output voltage.
Step 6: Prepare the Wires
Proper wire preparation ensures a secure connection.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch of insulation from each wire end. This exposes fresh copper for a solid connection.
Twist the Strands
If the wires are stranded (multiple thin wires), twist them tightly to prevent fraying.
Check Wire Length
The wires should be long enough to reach the Ring mounting bracket with some slack. If they’re too short, use wire extenders or fish new wires through the wall.
Optional: Use Wire Nuts
If extending wires, twist the old and new wires together and secure with a wire nut. Wrap with electrical tape for extra protection.
Step 7: Install the Ring Mounting Bracket
The mounting bracket holds the Ring doorbell securely in place.
Choose the Right Bracket
Ring includes a standard mounting bracket with most models. For angled installations, use the wedge or corner bracket (sold separately).
Position the Bracket
Hold the bracket against the wall where you want to install the doorbell. Use a level to ensure it’s straight.
Mark Screw Holes
Use a pencil to mark the screw hole locations.
Drill Pilot Holes
If mounting on wood, drill pilot holes slightly smaller than the screws. For brick or concrete, use a masonry bit and plastic anchors.
Secure the Bracket
Insert screws through the bracket and into the wall. Tighten until snug—don’t over-tighten, as this can crack the bracket.
Step 8: Connect the Wires to the Ring Doorbell
Now it’s time to connect the wires to your Ring device.
Locate the Terminal Screws
On the back of the Ring doorbell, you’ll see two terminal screws labeled “Front” and “Trans.” These correspond to the two doorbell wires.
Loosen the Screws
Use a screwdriver to loosen both screws just enough to slide the wires underneath.
Insert the Wires
Slide one wire under the “Front” screw and the other under the “Trans” screw. It doesn’t matter which wire goes where—Ring doorbells are not polarity-sensitive.
Tighten the Screws
Gently tighten the screws to secure the wires. Ensure no bare wire is exposed outside the terminal.
Double-Check Connections
Gently tug on the wires to confirm they’re secure. Loose wires can cause power issues.
Step 9: Mount the Ring Doorbell
With the wires connected, it’s time to attach the doorbell to the bracket.
Align the Device
Hold the Ring doorbell so the mounting tabs align with the bracket.
Slide Into Place
Gently slide the doorbell down onto the bracket until it clicks into place.
Secure with Screw (If Applicable)
Some models include a security screw to prevent theft. Use the provided tool to tighten it.
Check Stability
Give the doorbell a gentle shake to ensure it’s firmly attached.
Step 10: Restore Power and Test
Now that everything is connected, it’s time to power up and test the system.
Turn On the Breaker
Go back to the breaker box and switch the doorbell circuit back to “ON.”
Wait for the Device to Power Up
The Ring doorbell will take 30–60 seconds to boot up. You’ll see a light on the front (usually white or blue).
Open the Ring App
Launch the Ring app on your smartphone and log in.
Check Device Health
Go to “Devices” > select your doorbell > “Device Health.” Look for “Wired” under power source. If it says “Battery,” the wiring may not be connected properly.
Test the Doorbell
Press the doorbell button. You should hear the chime (if connected) and receive a notification on your phone.
Test Live View
Tap “Live View” in the app to confirm the camera is working and the stream is smooth.
