Before touching any wires, gather these essentials:
- Blink Doorbell Wired kit (includes doorbell, mounting plate, screws, wire nuts, and optional wedge)
- Screwdriver (Phillips head usually works best)
- Voltage tester (non-contact type recommended)
- Wire strippers (if you need to trim or expose fresh wire ends)
- Smartphone or tablet with the Blink app installed (iOS or Android)
- Stable Wi-Fi network (2.4 GHz band required; 5 GHz not supported)
- Ladder (if your doorbell is mounted high)
Pro tip: If your current doorbell has thin, brittle wires, consider replacing them with 18–22 gauge doorbell wire for better conductivity.
Step 1: Turn Off the Power
Safety first! Even though doorbell circuits run on low voltage, they can still give you a nasty shock—or worse, damage your new Blink doorbell if wired incorrectly.
Locate your electrical panel
Go to your home’s main breaker box. Look for a labeled circuit marked “doorbell,” “chime,” or something similar. If it’s not labeled, you may need to test circuits by turning them off one by one (more on that below).
Turn off the correct breaker
Switch the breaker to the “OFF” position. Use a non-contact voltage tester near the doorbell wires to confirm there’s no power. Touch the tester to each wire—if it beeps or lights up, power is still on. Double-check your breaker selection.
Alternative method: Test without labels
If your breakers aren’t labeled, turn off suspect breakers one at a time and test the doorbell button. When the chime stops ringing, you’ve found the right circuit. Then verify with your voltage tester.
⚠️ Never skip this step. Working on live wires risks injury and voids your warranty.
Step 2: Check Your Existing Wiring Compatibility
The Blink Doorbell Wired needs a constant power source, so your current setup must meet specific requirements.
Check transformer voltage
Most older doorbells use transformers that output 8–24 volts AC (alternating current). The Blink Doorbell Wired works within this range, but it also needs at least 10VA (volt-amperes) of power.
To check:
– Locate your doorbell transformer (usually near your furnace, in the basement, or inside the chime unit).
– Look for a label showing voltage (V) and VA rating.
– If it says “16V 10VA” or higher, you’re good to go.
If your transformer is below 8V or under 10VA, your doorbell may not power on consistently. In that case, you’ll need to upgrade the transformer—a job best left to a licensed electrician unless you’re experienced.
Inspect wire condition
Remove your old doorbell faceplate and examine the two wires connected to the terminals. They should be:
– At least 18-gauge thickness
– Not frayed, corroded, or brittle
– Long enough to reach the new mounting plate (about 3–4 inches exposed)
If the wires are damaged, carefully strip back the insulation to expose fresh copper. Use wire strippers to avoid nicking the conductor.
Confirm chime compatibility (optional)
The Blink Doorbell Wired can work with mechanical chimes (the classic “ding-dong” type) or digital chimes. However, some very old or high-impedance chimes might not trigger reliably. If your chime doesn’t ring after installation, you may need a resistor (sold separately) or to bypass the chime entirely (see troubleshooting section).
Step 3: Remove Your Old Doorbell
Now that power is off and wires are confirmed good, it’s time to remove the old unit.
Unscrew the faceplate
Use your screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the unit away from the wall—don’t yank it, as this can damage the wires inside the wall.
Disconnect the wires
Note which wire goes to which terminal (usually marked “Front” and “Trans” or just two screws). Take a photo for reference, then loosen the screws and remove the wires.
Tip: Twist the wire ends slightly to keep them from fraying while you work.
Cap the wires temporarily
Use wire nuts or electrical tape to cover the exposed ends. This prevents accidental contact while you prepare the new mount.
Step 4: Install the Blink Mounting Plate
The Blink Doorbell Wired comes with a sturdy mounting plate that holds the device securely and hides the wiring.
Position the plate
Hold the mounting plate against the wall where you want the doorbell. Make sure it’s level—use a spirit level or the leveling tool in your phone’s compass app.
The ideal height is about 48 inches from the ground, so most adults can see the camera clearly.
Mark screw holes
Use a pencil to mark where the screws will go. If you’re mounting into siding, brick, or stucco, you may need wall anchors (not included). For wood or drywall, the provided screws should work fine.
Drill pilot holes (if needed)
For harder surfaces, drill small pilot holes to prevent cracking. Then screw the mounting plate into place using the included screws.
Feed wires through the center
Push the two doorbell wires through the hole in the center of the mounting plate. Leave enough slack (about 3–4 inches) to connect to the Blink doorbell later.
Step 5: Connect the Wires to the Blink Doorbell
This is the most critical part—getting the wiring right ensures your doorbell powers on and communicates with your chime.
Prepare the wire ends
Strip about 1/4 inch of insulation from each wire if needed. Twist the copper strands tightly so they don’t unravel.
Attach wires to terminals
The Blink Doorbell Wired has two spring-loaded terminals on the back (no screws!). Simply insert one wire into each terminal and push until it clicks. It doesn’t matter which wire goes where—the doorbell is polarity-independent.
Double-check that both wires are fully seated and secure.
Secure the doorbell to the plate
Align the doorbell with the mounting plate and press firmly until it snaps into place. You’ll hear a click when it’s locked.
Optional: If your doorbell is on a corner or you want a better viewing angle, use the included wedge mount. Attach it to the wall first, then mount the plate to the wedge.
Step 6: Restore Power and Test the Hardware
Time to bring the system back to life—carefully!
Turn the breaker back on
Go to your electrical panel and flip the doorbell breaker to “ON.”
Listen for the chime
Press the doorbell button. You should hear your indoor chime ring. If not, don’t panic—we’ll troubleshoot in a moment.
Check for LED activity
On the front of the Blink doorbell, a small LED should glow solid blue for a few seconds, then blink blue rapidly. This means it’s powered and ready to connect.
If the LED doesn’t light up:
– Recheck your wiring connections
– Confirm the transformer is outputting adequate voltage
– Ensure the breaker is truly on
Step 7: Set Up the Blink Doorbell in the App
Now for the fun part—connecting your doorbell to your smartphone!
Download the Blink app
If you haven’t already, download “Blink Home Monitor” from the Apple App Store or Google Play.
Create or log in to your account
Open the app and sign in with your existing Blink account or create a new one (it’s free).
Add a new device
Tap the “+” icon, select “Doorbell,” then choose “Wired.”
Scan the QR code
Point your phone’s camera at the QR code on the back of the doorbell (or inside the battery compartment if you ever switch to battery mode). The app will detect it automatically.
Connect to Wi-Fi
Select your 2.4 GHz Wi-Fi network (5 GHz won’t work) and enter your password. The doorbell will join your network—this may take 30–60 seconds.
Name your doorbell and set preferences
Give it a name like “Front Door” and adjust settings like motion sensitivity, night vision, and notification schedules.
Test live view and two-way audio
Tap “Live View” in the app. You should see a clear video feed. Speak into your phone—you should hear yourself through the doorbell’s speaker. Press the doorbell button to test motion alerts.
Congratulations! Your Blink Doorbell Wired is now fully installed and operational.
Troubleshooting Common Installation Issues
Even with careful installation, hiccups can happen. Here’s how to fix the most common problems:
Doorbell won’t power on (no LED)
– Recheck breaker and voltage with a tester
– Ensure wires are firmly inserted into terminals
– Test transformer output—replace if below 8V or 10VA
– Try swapping wire positions (though polarity doesn’t matter, loose connections do)
Chime doesn’t ring
– Confirm mechanical chime is compatible (some digital chimes need resistors)
– Check that wires aren’t reversed at the chime unit itself
– Install a 100Ω, 5W resistor across the chime terminals (available online)
Weak or no Wi-Fi signal
– Move your router closer or add a Wi-Fi extender
– Ensure you’re using 2.4 GHz (not 5 GHz)
