4. Step-by-Step Guide: How to Connect an Intercom to a Smart Lock

Connecting an intercom system to a smart lock can greatly enhance your building’s security and convenience. Below is a comprehensive guide that walks through the typical integration process. While specific steps may vary depending on the brands and models used, the overall structure remains consistent across most systems.

Step 1: Assess Compatibility

Before installation, confirm that both the intercom and smart lock are compatible.

✅ Check if the intercom has relay output terminals (dry contact or NO/NC output)
✅ Confirm the smart lock can be triggered by a relay or third-party controller
✅ If using IP-based products, ensure they support API or cloud integration

Step 2: Gather Required Tools & Equipment

• Schroevendraaierset
• Power drill (if new holes are required)
• Draadstrippers
• Electrical tape or wire connectors
• Network cables (for IP systems)
• Multimeter (to test voltage and continuity)

Step 3: Wiring the Relay Output

For most analog or hybrid intercom systems:

1. Locate the relay output terminals on the intercom indoor unit.
2. Connect the relay output wires to the input terminals of the smart lock (or to a relay controller if needed).
3. Gebruik shielded cables for longer distances to prevent interference.

For IP-based systems:

• Use the management software or admin panel to link the intercom’s unlock command to the smart lock’s API.
• Some systems may require a middleware device like a relay controller or smart hub.

Step 4: Configure Unlock Settings

Most intercoms allow configuration of:

• Unlock delay time (e.g., door remains unlocked for 5 seconds)
• Trigger mode (manual, remote, or schedule-based)
• User permissions (who can unlock the door)

For smart locks, you may also need to:

• Pair the lock with a mobile app or cloud platform
• Set up admin and user accounts
• Schakel externe ontgrendeling via intercom trigger or app

Stap 5: Test het systeem

Once connected and configured:

• Simulate a visitor pressing the intercom panel
• Use the indoor unit to start a video call and press the unlock button
• Confirm that the smart lock responds appropriately

Step 6: Set Up Remote Access (Optional)

If you want users to unlock the door remotely:

• Ensure the intercom and smart lock are connected to the internet
• Use the respective mobile apps or unified management platform
• Consider cloud-based options for remote monitoring and unlock logs
