The included Door Station is specifically designed for retrofitting into a NuTone box.

  • Door station triggers phone to ring when visitor presses button
  • Landline phone service is not required
  • Station retrofits into a NuTone IR-6 or IA-70 rough-in box
  • Slot for optional 14mm pinhole camera
  • Controller supports up to two door stations

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.

DP38 Door Station with Camera Slot

The DoorBell Fon DP38 Door Station installs near a door and triggers your phone to ring when a visitor presses the button. Designed for retrofitting, all N-Series Door Stations mount into a NuTone IR-6 or IA-70 rough-in box. The DP38 model also features a slot for an optional pinhole camera (not included), allowing you to see live video of your visitors when connected to a video monitor.

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
  • DP38 Door Station, NuTone Mount

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