DIY Door Station Makes Door-To-Phone Communication Super Easy

If you want to install a DoorBell Fon intercom system without cutting a hole in the wall near your door, choose the basic DoorBell Fon Door Answering System. This complete kit comes with a Door Station that surface mounts for easy installation. A control unit connects the door station to your telephone. When a visitor presses the button on the door station, your phone rings and you can answer to talk with your visitor.

  • Door station triggers phone to ring when visitor presses button
  • Landline phone service is not required
  • Station surface-mounts for easy DIY installation
  • Controller supports up to two door stations
  • Optional accessory (not included) can trigger existing doorbell chime

The Heart of the System

The Doorbell Fon Main Controller is the base unit for the Doorbell Fon Answering System. When the button on the Door Station is pushed by a visitor, the Controller signals your phone to ring with a distinct tone that is different from a regular voice call. No programming or codes are needed. Just answer the telephone like you would for a regular call.

The control unit requires connection to only one incoming line and one door station. A second door station may be added to the controller to operate another entryway. The controller installs using a single pair of wire for power, control, signaling and voice. Any add-on components install on the same single pair.

Surface-Mount Door Station

The surface-mount Door Station easily installs on the surface of the wall and triggers your phone to ring when a visitor presses the button. It connects to the controller using a single pair wire.

Expandable Functionality

You can daisy-chain multiple controllers together to support additional Door Stations, if needed. With optional accessories (not included), you can also expand functionality of your Doorbell Fon system. Optional accessories include:

  • Inbound Trigger Relay (DP29-CI): Triggers external devices when a visitor presses the Door Station button. Can trigger external door chimes, cameras, lights, etc.
  • Telephone Keypad Relay Trigger (DP29-SW): Triggers an electronic door strike, allowing the user to unlock a door via telephone.

Kit Includes

  • Doorbell Fon Main Controller
  • Door Station, Surface-Mount

Note: Requires a telephone, not included. Landline phone service is NOT required.
