Answer Your Door By Phone Like A Regular Call

As the main control unit for the Doorbell Fon System, the Doorbell Fon Main Controller connects your telephone to at least one Doorbell Fon Door Station, allowing you to answer a door or gate by phone. One controller supports two Door Stations for two separate entryways. You can daisy-chain multiple controllers together to support additional Door Stations, if needed.

  • Landline phone service not required
  • Supports two separate entryways
  • Produces distinctive ring for each entryway
  • Built in call-waiting activates when phone is in use
  • Plugs into a standard power outlet

When a visitor pushes the button at the door station (sold separately), the controller triggers a distinctive ring at your phone, different from the ring for a regular voice call. You can then answer the phone and automatically connect to the Door Station. If you are already using the phone line when a door visitor calls, the controller's built-in call waiting will let you know by beeping.

The Doorbell Fon Main Controller installs using a single pair of wire for power, control, signaling and voice connection. All add on components install on same single pair.

Note: Requires a telephone and at least one Doorbell Fon Door Station (sold separately). Landline phone service is NOT required.

Simplicity: The DoorBell Fon is simple to install. All you need is two wires from the Door Intercom connecting to the Main Controller and your phone line to pass through this Main Controller.
