A detailed data sheet is also available online for reference.
Wiring Options for Existing Chimes
The ADC-VDB770 offers flexible wiring options to integrate with your existing chime system. You can choose to wire the doorbell to a single chime, two chimes, or operate it without a chime altogether, depending on your home’s setup and preferences.
Wiring to a Chime: Connect the doorbell wires to the appropriate terminals on your existing mechanical or digital chime. Ensure proper polarity for correct operation.
Wiring to Two Chimes: For larger homes, wiring to two chimes can extend the audible range. Follow the wiring diagram provided in the installation guide for this configuration.
Wiring Without a Chime: The ADC-VDB770 can function without a chime, relying on notifications sent to your Alarm.com app. This is ideal for users who prefer silent operation. You can even wire two doorbells to a mechanical chime. Always consult the detailed wiring guides available online for specific instructions and safety precautions.
Wiring to a Single Chime
Connecting the ADC-VDB770 to a single existing chime is a common installation method. Begin by ensuring your chime system is compatible – most mechanical and digital chimes will work. Important: Disconnect power to your chime system at the breaker before commencing any wiring.

Identify the chime terminals, typically labeled ‘TRANS’ (transformer), ‘FRONT’, and ‘REAR’. Connect the doorbell wires to these terminals, observing correct polarity. The ADC-VDB770 datasheet provides a detailed wiring diagram for various chime types.
Carefully secure the connections and restore power. Test the doorbell by pressing the button; the chime should sound. If it doesn’t, double-check the wiring and ensure the transformer provides sufficient voltage. Proper wiring guarantees reliable chime activation and seamless integration with your Alarm.com system; Refer to the Alarm.com documentation for troubleshooting steps.
Wiring to Two Chimes
For homes equipped with two chime units, wiring the ADC-VDB770 requires a slightly different approach. This setup is often found in larger residences or those with chimes located at opposite ends of the house. Caution: Always disconnect power at the breaker before beginning any electrical work.
At each chime location, identify the ‘TRANS’, ‘FRONT’, and ‘REAR’ terminals. Connect one wire from the doorbell to the ‘TRANS’ terminal at both chime locations. Then, connect another wire to the ‘FRONT’ terminal of the first chime and the ‘REAR’ terminal of the second chime. This creates a series circuit.
Secure all connections firmly and restore power. Test the doorbell to confirm both chimes activate. If only one chime sounds, verify the wiring sequence and ensure proper connections. Consult the Alarm.com documentation or a qualified electrician if you encounter difficulties. Proper wiring ensures both chimes function correctly with your Alarm.com system.
Wiring Without a Chime
If your home lacks an existing doorbell chime system, or you prefer not to connect the ADC-VDB770 to one, a specific wiring configuration is necessary. Important Safety Note: Disconnect power at the circuit breaker before commencing any wiring procedures.
You will need to install a provided resistor (typically 10-20 ohms, check your specific kit) across the doorbell terminals. This resistor simulates the load of a chime, preventing damage to the doorbell’s electronics. Connect one end of the resistor to the ‘TRANS’ terminal and the other end to either the ‘FRONT’ or ‘REAR’ terminal.
Ensure the resistor is securely connected and insulated. Restore power to the doorbell. The ADC-VDB770 will function normally, providing video and motion detection, but will not produce a chime sound inside the house. You can utilize the Alarm.com app for notifications instead. Always refer to the official Alarm.com documentation for the correct resistor value.
Wiring Two Doorbells to a Mechanical Chime
Connecting two Alarm.com doorbells (ADC-VDB770 series) to a single mechanical chime requires careful consideration and may not be universally compatible with all chime systems. Important Safety Note: Always disconnect power at the breaker before starting any wiring work.
Typically, mechanical chimes are designed for a single doorbell. Wiring two doorbells in parallel can sometimes overload the chime mechanism, leading to malfunction or damage. A relay might be necessary to isolate the two doorbell circuits. Connect one doorbell to the standard chime terminals (TRANS, FRONT).
The second doorbell will require the relay to trigger the chime when activated. Consult a qualified electrician for proper relay installation and wiring. Improper wiring can damage both the chime and the doorbells. Verify chime compatibility before proceeding. Alarm.com documentation provides specific guidance; always prioritize those instructions.
Mounting the Doorbell Camera

Proper mounting is crucial for optimal performance of your Alarm.com ADC-VDB770 video doorbell. Before installation, ensure the chosen location provides a clear view of the entryway and is within range of your Wi-Fi network. The doorbell can be mounted to a standard doorframe or a flat surface using the provided mounting bracket and screws.
Important: Disconnect power to the existing doorbell wiring before beginning. Carefully route the wires through the mounting bracket and connect them to the doorbell terminals. Securely attach the doorbell to the bracket, ensuring it’s firmly mounted to prevent movement.
Adjust the viewing angle after mounting to maximize coverage. Consider using the included wedge kit for an optimized viewing angle. Double-check all connections and ensure the doorbell is weatherproofed to protect against the elements. Refer to the detailed installation guide for specific mounting instructions and safety precautions.

Setup and Enrollment
Begin enrollment! Ensure your Alarm.com app is updated to version 4.14 or higher. An Apple or Android device is required for seamless setup and activation.
Alarm.com App Requirements (Version 4.14+)
Essential App Version: To fully utilize the features of your Alarm.com ADC-VDB770 series video doorbell (including Bronze, Silver, and White finishes), maintaining an updated Alarm.com app is crucial. Specifically, the Customer app must be version 4.14 or higher to successfully view live and recorded video feeds from the device.
Older versions of the app may exhibit compatibility issues, preventing you from accessing the doorbell’s video functionality. Regularly check for updates within your device’s app store (Apple App Store or Google Play Store) to ensure you’re running the latest version. This guarantees optimal performance and access to the newest features and security enhancements.
Device Compatibility: Beyond the app version, please note that operation of the ADC-VDB770 requires either an Apple or Android-based mobile device. The Alarm.com app is designed to function exclusively on these operating systems, providing a user-friendly interface for managing your video doorbell and security system.
Confirm your device meets these requirements before proceeding with the setup process to avoid potential complications. A stable internet connection is also necessary for both app updates and doorbell functionality.
Best Enrollment Practices
Streamlined Setup: For a smooth and efficient enrollment of your Alarm.com ADC-VDB770 series video doorbell (available in Bronze, Silver, and White), follow these best practices. Prior to beginning, ensure your Wi-Fi network is stable and operating on the 2.4 GHz frequency band – this is crucial for reliable connectivity.
Position the doorbell temporarily close to your Wi-Fi router during the initial setup process. This maximizes signal strength and minimizes potential connection issues. Have your Wi-Fi password readily available, as you’ll need it during enrollment. Avoid using special characters in your Wi-Fi password if possible, as these can sometimes cause compatibility problems.
Disable any VPNs or proxy servers on your mobile device during enrollment. These can interfere with the connection process. Ensure your Alarm.com account is active and in good standing. Finally, close any unnecessary apps running in the background on your smartphone to free up resources and improve performance.
