What You’ll Need Before You Begin

Before you start installing your Blink Doorbell Wired, gather the right tools and materials. Having everything ready will save time and reduce frustration.

Tools and Materials Checklist

• Blink Doorbell Wired unit
• Smartphone or tablet with the Blink app installed
• Screwdriver (usually Phillips head)
• Wire strippers
• Voltage tester (non-contact type recommended)
• Electrical tape
• Drill and drill bits (if mounting on brick or concrete)
• Wall anchors (if needed)
• Ladder (if your doorbell is high up)

Check Your Existing Doorbell System

Not all homes are compatible with the Blink Doorbell Wired. The device requires a working doorbell transformer that outputs between 16 and 24 volts AC. Most older homes have transformers in this range, but it’s important to verify.

To check:

1. Locate your doorbell transformer. It’s usually near your electrical panel, in the basement, attic, or garage.
2. Look for a label that shows the voltage output. If it says 16V, 18V, 20V, or 24V AC, you’re good to go.
3. If you can’t find the transformer or it’s labeled below 16V, you may need to upgrade it. Consult an electrician if unsure.

Also, ensure your existing doorbell wires are in good condition. Frayed or corroded wires should be replaced before installation.

Download and Set Up the Blink App

The Blink app is essential for setup and ongoing use. It’s available for free on the Apple App Store and Google Play.

To prepare:

• Download the app and create an account if you don’t have one.
• Make sure your phone is connected to your home Wi-Fi network (2.4 GHz only—Blink doesn’t support 5 GHz).
• Keep your phone nearby during installation for easy pairing.

Step 1: Turn Off the Power

Safety first! Working with electrical wiring can be dangerous if the power is on. Always turn off the circuit breaker that controls your doorbell before starting.

Locate the Correct Breaker

Doorbell circuits are often labeled as “Doorbell,” “Chime,” or “Front Door.” If not clearly marked:

• Turn off breakers one by one and test your existing doorbell.
• When the doorbell stops working, you’ve found the right breaker.
• Turn it off and place a piece of tape over it to prevent accidental reactivation.

Test the Wires

Use a non-contact voltage tester to double-check that power is off:

• Remove the old doorbell button (if present).
• Touch the tester to the exposed wires. If it beeps or lights up, power is still on—double-check the breaker.
• If no signal, it’s safe to proceed.

Step 2: Remove the Old Doorbell (If Applicable)

If you’re replacing an existing doorbell, you’ll need to remove it first.

Unscrew the Old Button

• Use a screwdriver to remove the mounting screws.
• Gently pull the button away from the wall.
• You’ll see two wires connected to the back. Do not cut them yet.

Label the Wires (Optional but Helpful)

Use small pieces of tape to label the wires (e.g., “Front” and “Transformer”) so you know which goes where. This is especially useful if you have multiple doorbells.

Secure the Wires

Tuck the wires back into the wall slightly, but leave enough exposed (about 1/2 inch) to work with. Use electrical tape to hold them in place if needed.

Step 3: Prepare the Wires for the Blink Doorbell

The Blink Doorbell Wired connects directly to your existing doorbell wires. Proper preparation ensures a solid connection.

Strip the Wire Ends

• Use wire strippers to remove about 1/4 inch of insulation from each wire.
• Twist the exposed copper strands to keep them neat.
• Avoid cutting the wires too short—you’ll need flexibility for connection.

Check Wire Length

If the wires are too short to reach the mounting plate:

• Carefully pull them out a bit more from the wall.
• If they’re still too short, you may need to extend them with wire nuts and additional low-voltage wire.
• Only attempt this if you’re comfortable with basic electrical work.

Step 4: Mount the Blink Doorbell Bracket

The Blink Doorbell comes with a mounting bracket that holds the device securely in place.

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 the screw holes with a pencil.

Drill Pilot Holes (If Needed)

• If mounting on wood, you can screw directly into the wall.
• For brick, stucco, or concrete, drill pilot holes and insert wall anchors.
• Use a drill bit slightly smaller than the anchors for a snug fit.

Attach the Bracket

• Align the bracket with the holes.
• Secure it with the provided screws using a screwdriver.
• Make sure it’s tight and level—this ensures the doorbell sits flush against the wall.

Step 5: Connect the Wires to the Blink Doorbell

Now it’s time to connect your home’s doorbell wires to the Blink device.

Identify the Terminals

On the back of the Blink Doorbell, you’ll see two terminals labeled “Front” and “Transformer.” These correspond to the two wires from your wall.

Attach the Wires

• Loosen the terminal screws slightly.
• Insert one wire into the “Front” terminal and the other into the “Transformer” terminal.
• Tighten the screws to secure the wires. Do not overtighten—this can damage the terminals.
• Give the wires a gentle tug to ensure they’re firmly connected.

Note: The Blink Doorbell is polarity-insensitive, meaning you don’t need to worry about which wire goes where. Either wire can connect to either terminal.

Tuck Wires Neatly

Once connected, gently push the excess wire back into the wall to avoid pinching or damage when mounting the doorbell.

Step 6: Attach the Blink Doorbell to the Bracket

With the wires connected, it’s time to mount the doorbell itself.

Align the Device

• Hold the Blink Doorbell against the bracket.
• Slide it down until it clicks into place.
• You should hear a secure snap—this means it’s locked in.

Secure with the Security Screw

• Use the small security screw (included) to fasten the doorbell to the bracket.
• This prevents theft or accidental removal.
• Store the screwdriver in a safe place—you’ll need it for future maintenance.

Step 7: Restore Power and Test the Doorbell

Now that everything is installed, it’s time to turn the power back on and test the system.

Turn On the Breaker

• Go back to your electrical panel.
• Turn the doorbell breaker back on.
• Wait a few seconds for the system to power up.

Check for Power

• The Blink Doorbell should light up or show a status LED.
• If it doesn’t power on, double-check your wiring and breaker.

Test the Chime

• Press the doorbell button.
• You should hear a chime inside your home (if you have a mechanical chime).
• If using a smart chime or no chime, the alert will come through the app.

Step 8: Set Up the Blink Doorbell in the App

The final step is syncing your doorbell with the Blink app for full functionality.

Open the Blink App

• Launch the app on your smartphone.
• Log in to your account.
