Step 1: Turn Off the Power
Safety comes first. Working with electrical wires can be dangerous if the power is still on. Even low-voltage doorbell systems can cause shocks or damage your new device.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “Doorbell,” “Chime,” or something similar. If there’s no label, you may need to test breakers one by one.
Turn Off the Correct Breaker
Switch off the breaker that controls your doorbell circuit. To confirm it’s off, go to your existing doorbell and press the button. If the chime doesn’t sound, the power is off.
Use a Voltage Tester
For extra safety, use a non-contact voltage tester near the doorbell wires. Touch the tester to the wires—if it beeps or lights up, power is still on. Double-check your breaker or try another one.
Pro Tip: Place a piece of tape over the breaker switch with “DO NOT TURN ON” written on it. This prevents someone from accidentally restoring power while you’re working.
Step 2: Check Doorbell Compatibility
Not all doorbell systems work with Blink wired models. The Blink doorbell requires a transformer that outputs between 8 and 24 volts AC (alternating current) and at least 10 volt-amperes (VA). Most modern doorbells meet this, but older homes may not.
How to Check Your Transformer
The transformer is usually located near your doorbell chime inside the house or in the basement, attic, or garage. It’s a small rectangular box with wires connected to it.
Read the Label
Look for a label on the transformer that lists voltage (V) and VA. For example, “16V 10VA” is perfect. If it says “12V 5VA,” it may not provide enough power.
Use a Multimeter (Optional)
If you’re unsure, use a multimeter to test the voltage. Set it to AC voltage, touch the probes to the transformer terminals, and read the output. It should be between 8V and 24V.
Note: If your transformer is below 8V or under 10VA, you may need to upgrade it. Consult an electrician if you’re not comfortable doing this yourself.
Step 3: Remove the Old Doorbell
Now that the power is off and compatibility is confirmed, it’s time to remove your existing doorbell.
Unscrew the Faceplate
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the unit away from the wall.
Disconnect the Wires
You’ll see two wires connected to the back—usually labeled “Front” and “Trans.” Loosen the screws or pull the wires out of the terminals. Be careful not to let the wires fall back into the wall.
Label the Wires (Optional but Smart)
Use tape or a marker to label the wires (e.g., “Front” and “Trans”) so you know which is which during reinstallation.
Inspect the Wires
Check for fraying, corrosion, or damage. If the wires are in bad shape, you may need to extend them or call an electrician.
Pro Tip: If the wires are too short, use the included wire nuts to connect extension wires. Strip about 1/2 inch of insulation and twist the wires together before capping with a wire nut.
Step 4: Prepare the Mounting Location
The Blink doorbell should be installed at a height of about 48 inches (4 feet) from the ground. This ensures clear video of visitors and prevents tampering.
Choose the Right Spot
Pick a location that’s:
- Close to your door
- Protected from direct rain (under an eave or awning)
- Within range of your Wi-Fi signal
- Not obstructed by plants, mailboxes, or decorations
Mark the Mounting Holes
Hold the Blink mounting bracket against the wall where you want to install it. Use a level to make sure it’s straight. Mark the screw holes with a pencil.
Drill Pilot Holes
Use a drill bit slightly smaller than your screws to drill pilot holes. This prevents the wall from cracking, especially if you’re mounting into brick, stucco, or concrete.
Insert Wall Anchors (If Needed)
If you’re not drilling into wood or studs, insert the included wall anchors into the pilot holes. Tap them gently with a hammer until flush.
Step 5: Connect the Wires to the Blink Doorbell
Now it’s time to connect your doorbell wires to the new Blink unit.
Strip the Wire Ends
Use wire strippers to remove about 1/2 inch of insulation from each wire. You should see bare copper underneath.
Attach Wires to the Bracket
The Blink mounting bracket has two terminal screws. Loosen them slightly, then insert one wire under each screw. Tighten the screws to secure the wires.
Important: It doesn’t matter which wire goes to which terminal—Blink doorbells are not polarity-sensitive. However, keep them separate to avoid short circuits.
Secure the Wires
Use electrical tape to wrap the connections for extra safety. This prevents wires from loosening over time.
Test the Connection (Optional)
If you have a multimeter, you can test for continuity. But this isn’t required—just make sure the wires are tight and not touching each other.
Step 6: Mount the Blink Doorbell
With the wires connected, it’s time to attach the doorbell to the wall.
Align the Bracket
Hold the mounting bracket over the pilot holes and align it with your pencil marks. Make sure it’s level.
Secure with Screws
Insert the screws through the bracket and into the wall. Tighten them firmly, but don’t over-tighten—this can crack the plastic.
Attach the Doorbell Unit
Slide the Blink doorbell onto the mounting bracket. You’ll hear a click when it’s securely in place. Give it a gentle tug to confirm it’s locked.
Adjust the Angle (If Needed)
Some Blink models allow slight angle adjustment. Tilt the doorbell slightly downward for better motion detection and video coverage.
Pro Tip: If your doorbell is mounted too high or too low, consider using a wedge mount (sold separately) to adjust the angle without re-drilling.
Step 7: Restore Power and Test
Now that everything is installed, it’s time to turn the power back on and test your doorbell.
Turn On the Breaker
Go back to your electrical panel and flip the doorbell breaker back on.
Wait for the Light
The Blink doorbell has a status light. When power is restored, it should flash blue, indicating it’s booting up.
Press the Doorbell Button
Press the button on the front of the unit. You should hear a chime (if connected to a chime) and see the light change.
Check for Live View
Open the Blink app on your phone. If the doorbell is connected, you should see a live video feed within a few seconds.
Note: If the light doesn’t turn on or the app shows “offline,” proceed to the troubleshooting section below.
Step 8: Set Up the Blink App
The Blink app is essential for managing your doorbell, receiving alerts, and viewing recordings.
Download the App
If you haven’t already, download the Blink Home Monitor app from the App Store (iOS) or Google Play (Android).
Create or Log In to Your Account
Open the app and sign in with your Blink account. If you don’t have one, tap “Create Account” and follow the prompts.
Add Your Doorbell
Tap the “+” icon and select “Add Device.” Choose “Doorbell” and follow the on-screen instructions.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the Blink doorbell or the quick start guide.
Connect to Wi-Fi
Enter your Wi-Fi network name (SSID) and password. The doorbell supports 2.4 GHz networks only—5 GHz is not compatible.
Complete Setup
The app will guide you through naming your doorbell, setting up motion zones, and enabling notifications. You can also link it to other Blink cameras or Alexa devices.
Test Two-Way Audio
Press and hold the talk button in the app while speaking. You should hear your voice through the doorbell’s speaker. Ask someone to stand outside and test the microphone.
