How to Install Smart Doorbell Wiring Simplisafe

Optional but Helpful

• Smartphone or tablet: For setup and testing via the SimpliSafe app.
• Assistant: A second pair of hands can help hold the doorbell during mounting.
• Ladder: If your doorbell is mounted high.

Step 1: Check Compatibility and Power Requirements

Not all doorbells are created equal—and not all homes are ready for a smart upgrade. Before you start tearing off old covers, take a moment to verify compatibility.

Confirm Your Doorbell Model

SimpliSafe offers a few doorbell options, but only certain models support wired installation. As of 2024, the SimpliSafe Video Doorbell Pro is the primary wired model. Make sure you have this version—not the battery-only model—before proceeding.

You can check the model number on the packaging or in the SimpliSafe app under “Devices.” If you’re unsure, visit the SimpliSafe website or contact customer support.

Check Your Existing Transformer

The transformer is the small box inside your wall or near your doorbell chime that steps down household voltage (120V) to a safer level (usually 8–24V) for the doorbell. Most older doorbells use 16V, but smart doorbells often need a bit more power.

To check your transformer:

1. Locate your doorbell chime—usually inside the front door or hallway.
2. Remove the cover to expose the wiring.
3. Look for a small metal or plastic box labeled “Transformer” with wires connected to it.
4. Check the voltage rating printed on the transformer (e.g., “16V AC” or “24V AC”).

If your transformer is rated between 8V and 24V AC, you’re likely good to go. If it’s below 8V or above 24V, you may need to replace it. A 16V or 24V transformer is ideal for SimpliSafe.

Tip: If you can’t find the transformer or aren’t sure, turn off the power and carefully disconnect the wires from the chime. Use a multimeter to test the voltage across the terminals. If it reads within the 8–24V range, you’re set.

Verify Wire Condition

Inspect the existing doorbell wires. They should be:

• At least 18-gauge (thicker is better).
• Undamaged, with no fraying or corrosion.
• Long enough to reach the new doorbell location.

If the wires are brittle, too short, or damaged, you may need to run new ones—this is more complex and may require professional help.

Step 2: Turn Off the Power

Safety first! Working with electricity can be dangerous, even at low voltages. Always turn off the power before handling wires.

Locate Your Circuit Breaker

Find your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “Doorbell,” “Front Door,” or something similar. If there’s no label, you may need to test breakers one by one.

Turn Off the Correct Breaker

Switch the breaker to the “OFF” position. To confirm it’s off, go to your doorbell and press the button. The chime should not sound. If it does, another breaker may be controlling it—turn off additional breakers until the chime is silent.

Important: Use a non-contact voltage tester at the doorbell wires to double-check. Touch the tester to the wires—if it beeps or lights up, power is still on. Never assume it’s safe without testing.

Label the Breaker (Optional but Smart)

Once you’ve found the right breaker, label it clearly (e.g., “Doorbell – Front”) so you or others can easily identify it in the future.

Step 3: Remove the Old Doorbell

Now that the power is off, it’s time to remove the existing doorbell.

Unscrew the Old Unit

Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull it away from the wall—there should be two wires connected to the back.

Disconnect the Wires

Loosen the terminal screws or pull the wires out of the back (depending on the model). Note which wire goes where—usually, it doesn’t matter for doorbells, but it’s good practice to remember.

Tip: Take a photo of the wiring before disconnecting. This can help if you get confused later.

Cap the Wires Temporarily

Use wire nuts or electrical tape to cover the exposed ends of the wires. This prevents them from touching each other or the wall, which could cause a short when power is restored.

Step 4: Prepare the New Wiring

With the old doorbell removed, it’s time to get the new one ready.

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.

Check Wire Length

Ensure the wires are long enough to reach the new doorbell’s terminals. If they’re too short, you may need to splice in extensions (use wire nuts and electrical tape).

Test the Wires (Optional)

If you’re unsure which wire is which, you can use a multimeter to test continuity or label them “Front” and “Trans” (for transformer) based on your chime wiring.

Step 5: Install the SimpliSafe Doorbell

Now for the fun part—mounting and wiring your new smart doorbell.

Position the Doorbell

Hold the SimpliSafe doorbell 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.

Tip: The ideal height is about 48 inches from the ground—eye level for most adults.

Drill Pilot Holes (If Needed)

If you’re mounting into wood, you can screw directly. For brick, stucco, or concrete, drill pilot holes and use wall anchors.

Connect the Wires

SimpliSafe doorbells typically have two terminals: one for the front wire and one for the transformer wire. It doesn’t matter which wire goes where—doorbell circuits are not polarity-sensitive.

1. Loosen the terminal screws on the back of the doorbell.
2. Insert one wire into each terminal.
3. Tighten the screws securely—don’t overtighten, but make sure the wires can’t slip out.

Alternative: Some models use push-in connectors. Simply insert the stripped wire ends into the designated slots.

Secure the Doorbell

Align the doorbell with the screw holes and press it firmly against the wall. Insert and tighten the mounting screws. Don’t overtighten—this can crack the casing.

Tuck Excess Wire

Gently push any extra wire back into the wall cavity to keep things neat.

Step 6: Restore Power and Test

You’re almost done! Now it’s time to see if everything works.

Turn the Power Back On

Go to your circuit breaker and switch the doorbell breaker back to “ON.”

Test the Doorbell

Press the doorbell button. You should hear the chime inside. If not, double-check:

• Are the wires securely connected?
• Is the transformer providing the correct voltage?
• Is the chime itself working?

Download and Open the SimpliSafe App

If the chime works, open the SimpliSafe app on your smartphone. Follow the on-screen instructions to add the doorbell:

1. Tap “Add Device.”
2. Select “Video Doorbell.”
3. Scan the QR code on the doorbell or enter the serial number.
4. Follow the setup prompts to connect to Wi-Fi and configure settings.

Test Video and Audio

Once connected, test the live view, motion detection, and two-way audio. Walk in front of the doorbell to trigger motion alerts. Speak through the app to test the microphone and speaker.

Troubleshooting Common Issues

Even with careful installation, problems can arise. Here’s how to fix the most common ones.

Doorbell Doesn’t Ring

• Check power: Ensure the breaker is on and the transformer is working.
• Inspect wires: Loose or disconnected wires are the #1 cause.
• Test the chime: Bypass the doorbell temporarily by connecting the wires directly to the chime. If it rings, the issue is with the doorbell.

No Video or Poor Connection

• Wi-Fi signal: Smart doorbells need strong Wi-Fi. Move your router closer or use a Wi-Fi extender.
• App issues: Force-close and reopen the SimpliSafe app. Restart your phone if needed.
• Firmware update: Check for updates in the app under “Device Settings.”

Doorbell Overheats or Shuts Off

• Transformer voltage too high: A 24V transformer may overpower some models. Check specs and replace if needed.
• Short circuit: Ensure wires aren’t touching each other or the wall.

Motion Alerts Not Working

• Adjust sensitivity: In the app, go to “Motion Settings” and increase sensitivity.
• Check placement: Avoid pointing the doorbell at moving trees or busy streets.
• Test at night: Some models have night vision issues—ensure IR LEDs are unobstructed.

Final Tips for a Successful Installation

• Take your time: Rushing leads to mistakes. Follow each step carefully.
• Keep the manual handy: SimpliSafe includes a quick-start guide—refer to it if you get stuck.
• Use the app for guidance: The SimpliSafe app often provides visual aids and troubleshooting tips.
• Don’t force connections: If a wire won’t fit, strip a bit more insulation—don’t bend or break the terminal.
• Label everything: If you have multiple wires, label them to avoid confusion.
