Pro Tip: If you’re unsure about your current doorbell voltage (most are 16V or 24V), check the transformer label or consult your doorbell manual. Mismatched voltage can damage your chime.
Step 1: Choose the Right Extra Chime
Not all doorbell chimes are created equal. Your choice depends on your existing system and installation preferences.
Wired vs. Wireless Chimes
Wired chimes connect directly to your doorbell circuit via low-voltage wires. They’re reliable, don’t require batteries, and integrate seamlessly with your current setup. However, they require running new wires, which can be tricky in finished walls.
Wireless chimes use radio signals to communicate with your existing doorbell button. You plug the receiver into a wall outlet, and it chimes when the button is pressed. No wiring needed—just plug and play. Great for renters or quick fixes.
Compatibility Check
- Check your current doorbell brand and model.
- Look for chimes labeled “compatible with [your brand]” or “universal.”
- Ensure voltage matches (usually 16V AC).
- For wireless systems, confirm frequency compatibility (most use 315MHz or 433MHz).
Example: If you have a Ring Video Doorbell wired to a mechanical chime, you can add a second wired chime from the same brand or a compatible third-party unit like the Nutone C907.
Step 2: Turn Off the Power
Safety first! Even though doorbell systems use low voltage, they’re still connected to your home’s electrical circuit via a transformer. Accidentally touching live wires can cause shocks or damage components.
Locate the Doorbell Transformer
The transformer steps down your home’s 120V power to 16V or 24V for the doorbell. It’s usually found in one of these places:
- Inside the electrical panel (look for a small black box labeled “doorbell” or “transformer”)
- In the basement near the furnace
- Inside a closet or attic junction box
- Behind the existing chime unit (less common)
Shut Off Power at the Breaker
- Turn off the breaker that controls the transformer. If unsure, turn off the main breaker.
- Use a non-contact voltage tester on the doorbell wires to confirm power is off.
- Place a piece of tape over the breaker switch with “DO NOT TURN ON – WORK IN PROGRESS” written on it.
Warning: Never skip this step. Even low-voltage systems can cause injury if mishandled.
Step 3: Remove the Existing Chime Cover
Now that power is off, it’s time to access your current chime unit.
Unscrew the Cover
- Most chimes have a front cover held by 2–4 screws.
- Use a screwdriver to remove them gently.
- Set screws aside in a small container so they don’t get lost.
Label the Wires
This is crucial! Your doorbell has at least two wires:
- Front (F): Connects to the front door button.
- Transformer (T): Connects to the power source.
- Rear (R): Optional, for a second door (like a back door).
Use colored tape or a marker to label each wire before disconnecting. For example:
- Red wire → “Front”
- White wire → “Transformer”
- Blue wire → “Rear” (if present)
Pro Tip: Take a photo of the wiring before disconnecting. It’s a great reference if you get confused later.
Step 4: Plan the New Chime Location
Where should you install the extra chime? Consider these factors:
- Hearing range: Place it where it’s most likely to be heard (e.g., master bedroom, kitchen, basement).
- Accessibility: Avoid areas behind furniture or appliances.
- Wiring path: For wired chimes, choose a location near an existing wall cavity or baseboard for easier wire routing.
- Aesthetics: Match the style of your existing chime if possible.
Example: If your main chime is in the hallway, install the extra one in the bedroom or home office.
Step 5: Run the Wiring (For Wired Chimes)
This is the most involved step for wired installations. If you’re using a wireless chime, skip to Step 6.
Choose Your Wire Path
You have a few options:
- Through walls: Remove baseboards or drill through studs. Best for clean, hidden wiring.
- Along baseboards: Use wire molding or adhesive cable clips. Easier but visible.
- Under carpet: Only if safe and permitted (not recommended for high-traffic areas).
Drill and Feed the Wire
- Drill a small hole (¼ inch) from the existing chime location to the new one.
- Use a fish tape or flexible rod to pull the wire through.
- Leave extra slack (6–12 inches) at both ends for connections.
Safety Note: Avoid drilling into electrical wires, plumbing, or structural beams. Use a stud finder to check wall contents.
Strip and Prepare Wires
- Strip about ½ inch of insulation from each wire end.
- Twist the copper strands tightly to prevent fraying.
- If using wire nuts, choose the right size (usually red or yellow for doorbell wire).
Step 6: Connect the Extra Chime
Now it’s time to wire everything together.
Wired Chime Connection
Most extra chimes connect in parallel with the existing one. Here’s how:
- At the existing chime, disconnect the labeled wires.
- Connect the new chime wires to the same terminals:
- New “Front” wire → Existing “Front” terminal
- New “Transformer” wire → Existing “Transformer” terminal
- Use wire nuts or terminal screws to secure connections.
- Wrap connections with electrical tape for extra safety.
Diagram Tip: Think of it like adding a second light to a circuit—both chimes share the same power and signal.
Wireless Chime Setup
- Plug the wireless receiver into an outlet near the desired location.
- Follow the manufacturer’s pairing instructions (usually press a sync button on both units).
- Test by pressing the doorbell button.
Note: Some wireless chimes require batteries. Replace them annually or when sound weakens.
Step 7: Mount the New Chime
Secure the chime to the wall or electrical box.
Mounting Options
- Surface mount: Use screws and wall anchors. Ideal for plaster or drywall.
- Flush mount: Install in an electrical box inside the wall. Cleaner look but requires cutting drywall.
Steps to Mount
- Hold the chime against the wall and mark screw holes.
- Drill pilot holes and insert wall anchors if needed.
- Screw the chime base into place.
- Attach the cover.
Pro Tip: Use a level to ensure the chime is straight. A crooked chime looks unprofessional.
Step 8: Restore Power and Test
You’re almost done!
Turn Power Back On
- Remove the breaker tape.
- Flip the breaker back on.
- Wait 10–15 seconds for the system to reset.
Test the System
- Press the doorbell button.
- Listen for chimes at both locations.
- If only one chimes, check wiring connections.
- If neither chimes, recheck power and transformer.
- Check power: Confirm the breaker is on and the transformer is working.
- Test voltage: Use a multimeter to check for 16V at the chime terminals.
- Inspect wires: Look for loose, corroded, or disconnected wires.
- Replace chime: If all else fails, the new chime may be defective.
- Overloaded transformer: Too many chimes can exceed the transformer’s capacity. Upgrade to a 15W or 20W model.
- Long wire runs: Voltage drops over distance. Use thicker wire (16-gauge) for runs over 50 feet.
- Corroded contacts: Clean terminals with sandpaper or replace wire nuts.
- Distance: Move the receiver closer to the doorbell button (within 100–300 feet).
- Interference: Avoid placing near microwaves, Wi-Fi routers, or cordless phones.
- Batteries: Replace old batteries in the button or receiver.
- Reset: Follow the manufacturer’s reset procedure (usually hold sync button for 10 seconds).
- Loose wires: Tighten all connections.
- Faulty button: Replace the doorbell button if it sticks or shorts.
- Weather issues: Moisture can cause false triggers. Seal outdoor buttons with silicone.
- Always turn off power before working.
- Use insulated tools.
- Never work on live circuits.
- Keep water away from electrical components.
- In some areas, modifying electrical systems requires a permit.
- If you’re unsure, consult a licensed electrician.
- Renters should check lease agreements before making modifications.
- You’re uncomfortable working with wires.
- The wiring path is complex (e.g., through multiple floors).
- Your home has aluminum wiring (requires special connectors).
- You need to upgrade the transformer or panel.
- Test the chime monthly.
- Clean the button and chime covers with a dry cloth.
- Check for loose wires or corrosion.
- Replace batteries in wireless units.
- In winter, clear snow and ice from the button.
- In humid climates, inspect for moisture damage.
Troubleshooting Tip: If the chime sounds weak or distorted, the transformer may be overloaded. Consider upgrading to a higher-wattage transformer (e.g., 10W to 15W).
