Key Takeaways
- Yes, you can connect 2 Ring Doorbells to one transformer, but it must handle the combined power (16-24V AC, 30VA or higher).
- Ring Doorbells typically require 16-24V AC and 1-2 amps (or 0.5-1 amp for battery models).
- Select a higher-wattage transformer with a surge protector for best results.
- After wiring, add the second doorbell to the Ring app.
Integrating two Ring Doorbells on one transformer simplifies your home security, but it’s only possible if your transformer has enough power. In this post, I’ll guide you about choosing a transformer that can handle the load and how to connect both doorbells to it.
Can You Connect 2 Ring Doorbells on One Transformer?
Yes, you can connect two Ring Doorbells to a single transformer, provided it has enough power to support both devices. Typically, a transformer rated at 16-24V AC with at least 30VA is recommended for multiple doorbells.
Transformers convert standard 120V AC (common in the U.S.) to 16V AC for doorbells. If your current transformer isn’t sufficient, upgrade to one with a higher VA rating. Choosing a transformer with a built-in surge protector is also a smart move to guard against power spikes.
How Many Volts & Amperes Do Ring Doorbells Need?
Here’s a quick reference for the voltage and amperage needs of common Ring Doorbell models:
| Ring Doorbell Model | Voltage Requirement | Ampere Requirement |
|---|---|---|
| Ring Video Doorbell Wired | 16-24V AC | 1-2 A (30VA) |
| Ring Video Doorbell Pro/Pro 2 | 16-24V AC | 1-2 A (30VA) |
| Ring Video Doorbell (Battery-Powered Models with Optional Hardwiring) | 8-24V AC | Approx. 0.5-1 A (10-20VA) |
How to Choose the Right Transformer for Multiple Doorbells
When connecting two Ring Doorbells on one transformer, selecting the correct transformer is crucial to ensure proper functionality. Here’s what to consider:
- 🔌 Voltage Requirements: Choose a transformer delivering 16-24V AC for compatibility with most Ring devices.
- ⚡ Power Rating (VA): Opt for a transformer with at least 30VA to support two doorbells.
- ✔️ Compatibility: Ensure the transformer matches the specific power needs of your Ring models.
- 📈 Future-Proofing: If you plan to add more devices, select a transformer with a higher VA rating.
- 🛡️ Safety Features: Look for UL-certified transformers with thermal and overload protection.
- 🔧 Installation Type: Choose between wired or plug-in transformers based on your setup.
How to Wire Two Ring Doorbells to a Single Transformer: Step-by-Step
When wiring two Ring Doorbells to a single transformer, it’s essential to follow the correct process to ensure safe and efficient installation. But before starting, turn off the power at the breaker and use a voltage tester to confirm no current is flowing.
What You Need:
- Transformer (16-24V AC, 30VA or higher)
- Wire nuts
- Screwdriver
- Doorbell wire (18 AWG recommended)
- Electrical tape
- Voltage tester
Now, follow these steps to wire 2 Ring Doorbells on one transformer:
- If you’re replacing an existing transformer, find it (typically near your electrical panel or HVAC system).
- If the transformer is new, mount it in a suitable location near your circuit breaker or electrical panel.
- Connect the transformer’s primary wires to a 120V AC power source as per the manufacturer’s instructions.
- If using a doorbell chime, run two wires from the transformer to the chime’s TRANS terminal. Skip this step if no chime is needed.
- Connect both Ring Doorbells to the same transformer terminals. Run one wire from the positive terminal to each doorbell’s positive terminal, and another from the negative terminal to each doorbell’s negative terminal.
- Use wire nuts to safely secure the connections, and wrap them with electrical tape for added safety.
- After wiring, use a voltage tester to confirm that both doorbells are receiving the correct voltage (16-24V AC).
- Once the wiring is complete, mount the Ring Doorbells, switch the breaker back on, and check that the doorbells power up correctly.
- Use the Ring app to check both doorbells, ensuring motion detection and power are working properly.
Do You Need a Power Kit for Multiple Ring Doorbells?
Yes, a power kit is often necessary when connecting multiple Ring Doorbells, especially if you’re using a chime. Here’s why:
- ⚡ Regulates Power Flow: Ensures consistent voltage and current, preventing performance issues.
- 🛡️ Prevents Overloads: Manages the increased load when two doorbells share one transformer.
- 🔔 Maintains Chime Functionality: Keeps your mechanical or digital chime working smoothly.
- ⚠️ Reduces Surges: Protects against power surges caused by both doorbells activating simultaneously.
How to Add a Second Doorbell to the Ring App
After wiring 2 Ring Doorbells to one transformer, you need to add the second one to your Ring app. Here’s how to do it:
- Open the Ring app and log in.
- Tap the menu icon (three lines) and select Set Up a Device.
- Choose Doorbells.
- Scan the QR code or manually enter the 5-digit PIN.
- Follow the in-app instructions to connect the new Doorbell to Wi-Fi.
- Name the Doorbell and set your location.
- Customize settings like motion detection and notifications.
- Test the doorbell to ensure it’s working.
🔔 Pro Tip: Name each Ring Doorbell uniquely (e.g., “Front Door, Backyard”) and set different alert tones to easily know which one is activated without checking your phone.
Two Ring Doorbells, One Transformer
Integrating multiple Ring Doorbells with one transformer boosts security without complicating installation. Just ensure the transformer meets the power needs of all doorbells.
Here’s more on Ring Doorbell:
- You can use Ring Doorbell without WiFi, but only as a traditional doorbell.
- You can use Ring Doorbell local storage to save videos with Ring Edge.
- If your Ring Doorbell is dead after charging or hardwiring, check the battery, perform a hard reset, improve Wi-Fi, update firmware, and try charging via USB.
