Step 1: Check Compatibility and Power Requirements
Not every home is ready for a Google Doorbell Wired. Before you start, you need to confirm that your existing doorbell system can support it.
Check Your Existing Doorbell Wiring
Most homes with a traditional doorbell have low-voltage wiring running from a transformer to the doorbell button and chime. The Google Doorbell Wired requires:
- 16–24 volts AC (alternating current)
- At least 500mA (0.5A) of power
If your current doorbell uses batteries only, you’ll need to install wiring and a transformer—this is a more advanced project and may require an electrician.
Locate Your Doorbell Transformer
The transformer steps down your home’s 120V power to the lower voltage needed for the doorbell. It’s usually found in one of these places:
- Basement near the electrical panel
- Garage ceiling or wall
- Utility closet
- Attic (less common)
Look for a small black or gray box with wires coming out and a label that says “16V” or “24V.” If you can’t find it, check your electrical panel or consult an electrician.
Test the Voltage
This is critical. Use a non-contact voltage tester or a multimeter to check the voltage at the doorbell button:
- Remove the old doorbell button.
- Touch the multimeter probes to the two wires.
- Set the meter to AC voltage (V~).
- You should see a reading between 16 and 24 volts.
If the voltage is too low (under 16V), the doorbell may not work properly. If it’s too high (over 24V), it could damage the device. In either case, you may need to replace the transformer.
Pro Tip: If you’re unsure about voltage or wiring, hire a licensed electrician. It’s better to be safe than sorry.
Step 2: Turn Off the Power
Safety first! Working with electricity can be dangerous if you don’t take the right precautions.
Shut Off the Circuit Breaker
- Go to your main electrical panel.
- Locate the breaker that controls your doorbell (it may be labeled “doorbell,” “chime,” or “front door”).
- Switch it to the OFF position.
If you can’t identify the right breaker, turn off the main power or test each one by turning them off one at a time and checking if the doorbell stops working.
Double-Check with a Voltage Tester
Even after turning off the breaker, use your voltage tester to confirm no power is reaching the doorbell wires. Touch the tester to each wire—there should be no indication of voltage.
Never skip this step. A live wire can cause serious injury.
Step 3: Remove the Old Doorbell
Now that the power is off, it’s time to remove your existing doorbell button.
Unscrew the Old Button
- Use a screwdriver to remove the screws holding the old doorbell in place.
- Gently pull the button away from the wall.
- You’ll see two wires connected to the back.
Disconnect the Wires
- Loosen the terminal screws or pull the wires out of the back.
- Note which wire goes where—though polarity doesn’t matter for AC, it’s good practice to remember.
- If the wires are short or damaged, use wire strippers to expose fresh copper (about 1/4 inch).
Tip: Take a photo of the wiring before disconnecting. This can help if you need to troubleshoot later.
Cap the Wires (Temporarily)
Twist a wire nut onto each exposed wire to prevent them from touching each other or the wall. This keeps things safe while you work.
Step 4: Install the Mounting Bracket
The Google Doorbell Wired comes with a mounting bracket that attaches to your wall. This bracket holds the doorbell securely and allows for easy removal if needed.
Position the Bracket
- Hold the bracket against the wall where you want to install the doorbell.
- Use a level to make sure it’s straight.
- Mark the screw holes with a pencil.
Ideal Height: Install the doorbell about 48 inches (4 feet) from the ground. This is eye level for most adults and ensures good camera angle.
Drill Pilot Holes (If Needed)
If you’re mounting into wood or need extra support:
- Use a drill bit slightly smaller than your screws.
- Drill pilot holes at the marked spots.
- This prevents the wood from splitting.
For brick, concrete, or stucco walls, use a masonry drill bit and wall anchors.
Secure the Bracket
- Align the bracket with the holes.
- Insert screws and tighten with a screwdriver.
- Make sure the bracket is snug and doesn’t wobble.
Step 5: Connect the Wires to the Doorbell
Now it’s time to connect your home’s wiring to the Google Doorbell Wired.
Prepare the Wires
Remove the wire nuts from the two doorbell wires. If the ends are frayed or too short, trim and strip them again to expose clean copper.
Attach Wires to the Doorbell
The Google Doorbell Wired has two terminal screws on the back:
- Loosen the screws slightly.
- Insert one wire under each screw.
- Tighten the screws to secure the wires.
Note: Since this is AC power, it doesn’t matter which wire goes to which terminal. Both will work.
Use Wire Nuts for Extra Security (Optional)
For added safety, you can twist the wires together with a wire nut before attaching them to the doorbell. This reduces strain on the terminals.
Step 6: Attach the Doorbell to the Bracket
With the wires connected, it’s time to mount the doorbell.
Align and Slide Into Place
- Hold the doorbell so the mounting tabs align with the bracket.
- Gently slide it down until it clicks into place.
- You should hear a secure snap.
Secure with the Security Screw
- Use the small security screw (included) to lock the doorbell to the bracket.
- This prevents theft or accidental removal.
- Tighten with a screwdriver, but don’t over-tighten.
Pro Tip: If the doorbell feels loose, double-check that the wires aren’t pulling it out of alignment.
Step 7: Turn the Power Back On
Now that everything is connected, it’s time to restore power.
Flip the Circuit Breaker
Go back to your electrical panel and turn the doorbell breaker back to the ON position.
Check for Power
Wait about 30 seconds. The Google Doorbell Wired should power on automatically. You’ll see a light on the front:
- Solid white: Power is on, and it’s ready to connect.
- Blinking white: It’s in pairing mode.
- No light: There’s a problem—check wiring and voltage.
If there’s no light, go back and double-check your connections and voltage.
