How to Get Wired Doorbell to Chime in Two Places

This guide walks you through how to get a wired doorbell to chime in two places using parallel wiring or additional chime units. No rewiring nightmares—just clear, safe, step-by-step instructions to ensure you never miss a visitor again.

Key Takeaways

Use parallel wiring: Connecting two chimes in parallel ensures both ring when the button is pressed, without overloading the transformer.
Check transformer compatibility: Your doorbell transformer must supply enough voltage and current to power multiple chimes—typically 16–24V AC with at least 10–15VA.
Choose compatible chime units: Both chimes should match the voltage and frequency of your existing system to avoid damage or weak sound.
Label wires clearly: Prevent confusion during installation by marking front, rear, and transformer wires before disconnecting anything.
Test before finalizing: Always test the system after wiring to confirm both chimes work and sound clearly.
Consider wireless alternatives: If running wires is too difficult, wireless chime extenders offer a plug-and-play solution.
Prioritize safety: Turn off power at the breaker before working on any electrical components to prevent shocks.

Before jumping into installation, it helps to understand the basics of a wired doorbell system. Most traditional doorbells use low-voltage AC power (usually 16–24 volts) from a transformer connected to your home’s electrical circuit.

Here’s a quick breakdown of the components:

Doorbell button: Mounted outside, it completes the circuit when pressed.
Transformer: Steps down household voltage (120V) to a safe, low voltage for the doorbell.
Chime unit: The indoor box that makes the “ding-dong” sound when the circuit is activated.
Wiring: Typically two low-voltage wires run from the transformer to the button and chime.

When you press the doorbell button, it sends power through the wires to the chime, triggering the sound. To add a second chime, you need to ensure that both units receive power simultaneously when the button is pressed—without overloading the system.

Option 1: Wiring Two Chimes in Parallel (Recommended)

The most reliable and common method to get a wired doorbell to chime in two places is by wiring the chimes in parallel. This means both chime units are connected to the same power source and doorbell button, so they activate at the same time.

What You’ll Need

Second compatible doorbell chime unit
Low-voltage electrical wire (18–22 gauge, typically 2-conductor)
Wire strippers
Screwdrivers (flathead and Phillips)
Electrical tape or wire nuts
Voltage tester (optional but recommended)
Labels or colored tape (to mark wires)

Step 1: Turn Off the Power

Safety first! Even though doorbell systems use low voltage, it’s still connected to your home’s electrical circuit. To avoid any risk of shock:

Locate your home’s main electrical panel (breaker box).
Find the breaker that controls the doorbell transformer. It’s often labeled “doorbell,” “chime,” or “low voltage.” If not labeled, turn off the main breaker to be safe.
Use a voltage tester at the chime unit to confirm power is off.

Step 2: Remove the Existing Chime Cover

Unscrew and remove the cover of your current doorbell chime. You’ll see three terminals inside:

Front (F): Connects to the front doorbell button.
Rear (R): Connects to a rear doorbell button (if you have one).
Transformer (T or Trans): Connects to the power source.

If you only have a front doorbell, the “Rear” terminal may be unused or connected to a jumper wire.

Step 3: Identify and Label the Wires

Before disconnecting anything, label each wire with tape or a marker:

Label the wire from the front button as “Front.”
Label the wire from the transformer as “Transformer.”
If you have a rear button, label that wire “Rear.”

This prevents confusion when reconnecting wires later.

Step 4: Disconnect the Wires

Carefully unscrew the terminal screws and remove the wires. Keep them organized so you know where each one goes.

Step 5: Prepare the Second Chime

Take your second chime unit and locate its terminals. Most chimes have the same three terminals: Front, Rear, and Transformer.

If your second chime is a different brand or model, check the manual to confirm terminal labels. Some use “Common,” “Front,” and “Trans” instead.

Step 6: Connect the Wires in Parallel

Now comes the key step: wiring both chimes in parallel.

Here’s how:

Take the Transformer wire from the original chime and connect it to the Transformer terminal on the first chime.
Run a new wire from the Transformer terminal on the first chime to the Transformer terminal on the second chime. This shares the power source.
Take the Front button wire and connect it to the Front terminal on the first chime.
Run another new wire from the Front terminal on the first chime to the Front terminal on the second chime. This ensures both chimes receive the signal when the button is pressed.

If you have a rear doorbell, repeat the same process for the Rear terminal.

Use wire nuts or electrical tape to secure connections if needed. Make sure no bare wire is exposed.

Step 7: Mount the Second Chime

Choose a location for the second chime—ideally in a room where you often miss the original chime, like a bedroom, basement, or garage.

Mount the chime unit to the wall using screws. Make sure it’s secure and the wires are tucked neatly behind it.

Step 8: Restore Power and Test

Go back to the breaker box and turn the power back on.

Press the doorbell button. Both chimes should ring simultaneously.

If only one chimes, double-check your wiring. Ensure all connections are tight and correct.

Option 2: Using a Wireless Chime Extender

If running new wires seems too complicated or your home layout makes it impractical, a wireless chime extender is a great alternative.

These devices consist of two parts:

A transmitter that plugs into your existing chime unit.
A receiver (the second chime) that you place anywhere in your home.

When the doorbell button is pressed, the transmitter sends a wireless signal to the receiver, which chimes.

Pros of Wireless Extenders

No new wiring required.
Easy to install—usually plug-and-play.
Portable; you can move the receiver to different rooms.
Works with most wired doorbell systems.

Cons of Wireless Extenders

Requires batteries or power outlet for the receiver.
Signal range may be limited (typically 100–300 feet, less through walls).
Potential for interference from other wireless devices.

How to Install a Wireless Chime Extender

Plug the transmitter into the existing chime unit’s power terminals (follow the manufacturer’s instructions).
Plug the receiver into an outlet in the desired location.
Pair the devices according to the manual (usually by pressing a sync button).
Test the system by pressing the doorbell button.

Popular brands include Ring, Heath Zenith, and SadoTech. Look for models with adjustable volume and multiple chime tones.

Option 3: Adding a Second Transformer (Advanced)

In rare cases, your existing transformer may not provide enough power for two chimes—especially if they’re older or high-power models.

If you notice weak sound, delayed ringing, or the chimes don’t work at all after installation, your transformer may be underpowered.

How to Check Transformer Capacity

Look at the transformer’s label. It should list voltage (V) and VA (volt-amperes).
Most standard doorbells use 16V, 10–15VA transformers.
Two chimes typically require at least 15–20VA.

If your transformer is below 15VA, consider upgrading to a 16V, 20VA or 24V, 20VA model.

Installing a Second Transformer

This is more complex and should only be done if you’re comfortable with electrical work.

Turn off power at the breaker.
Install a second transformer in parallel with the first (same voltage, connected to the same circuit).
Connect the new transformer to the second chime.
Ensure both transformers are properly grounded and secured.

Note: This method is rarely needed. Most modern chimes are low-power, and a single 16V, 15VA transformer can handle two units.

Troubleshooting Common Issues

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

Only One Chime Rings

Cause: Incorrect wiring or loose connection.
Solution: Double-check that both chimes are connected to the same Front and Transformer terminals. Ensure wires are tight and not crossed.

Chimes Are Weak or Muffled

Cause: Underpowered transformer or long wire runs causing voltage drop.
Solution: Upgrade to a higher VA transformer or use thicker wire (16–18 gauge) for longer runs.

Chimes Don’t Ring at All

Cause: Power is off, wires are disconnected, or the transformer is faulty.
Solution: Check the breaker, test the transformer with a multimeter, and verify all connections.

Chimes Ring Randomly or Continuously

Cause: Short circuit in the wiring or a faulty doorbell button.
Solution: Inspect wires for damage, replace the button if needed, and ensure no wires are touching.

Wireless Extender Has Poor Range

Cause: Obstacles like concrete walls or interference from Wi-Fi routers.
Solution: Move the receiver closer to the transmitter, or use a model with a stronger signal (e.g., 915 MHz instead of 433 MHz).

Safety Tips and Best Practices

Working with electricity—even low-voltage—requires caution. Follow these safety guidelines:

Always turn off power at the breaker before touching any wires.
Use a voltage tester to confirm power is off.
Label all wires before disconnecting them.
Use wire nuts or electrical tape to secure connections—never leave bare wires exposed.
Don’t overload the transformer. If in doubt, upgrade to a higher VA model.
Follow manufacturer instructions for both chime units and transformers.

If you’re unsure at any point, consult a licensed electrician. It’s better to be safe than sorry.

Choosing the Right Chime Units

Not all doorbell chimes are created equal. When selecting a second chime, consider:

Voltage compatibility: Must match your transformer (usually 16V or 24V AC).
Sound quality: Look for clear, loud tones. Some chimes offer multiple melodies.
Size and design: Choose a style that fits your home’s decor.
Ease of installation: Some chimes are easier to wire than others.
Brand reputation: Stick with trusted brands like Nutone, Heath Zenith, or Ring.

You can often use a different brand for the second chime, but ensure voltage and terminal layout are compatible.

Alternative: Smart Doorbells with Multiple Chimes

If you’re open to upgrading your entire system, consider a smart doorbell like Ring or Nest. These devices connect to Wi-Fi and can send alerts to your phone, tablet, or smart speaker.

Many smart doorbells also support multiple indoor chimes via wireless receivers or Alexa/Google Home integration.

For example:

Ring Doorbell + Ring Chime Pro: Extends Wi-Fi and adds a loud indoor chime.
Nest Hello + Google Nest Hub: Chimes on the screen and speaker.

While not strictly “wired,” these systems offer the same benefit—hearing the doorbell in multiple places—with added features like video and motion alerts.
