Doorbell Fon DP29SW-IM Door Strike Controller | DBF-DP29SW/IM

The Telephone Keypad Relay Trigger combines 2 former products into 1 device. Just by changing jumper settings, the DP29-SW or the DP29-IM can be selected. Both devices modify the telephone keypad to enhance your DoorBell Fon system.

DP29-SW: The Outbound Relay Trigger Controller will enhance the existing DoorBell Fon system by providing dry contact closure off the star (*) key or any other key selected by the DIP switch S1. This product is a great add-on that will trigger any electrical devices that you may want to operate from your telephone just by pressing a keypad button. The DP29-SW is also known as the Door Strike Controller.

DP29-IM: The Intercom Module will enhance the existing DoorBell Fon system by converting all the phones in your home or office into an intercom system. No new wiring is required and no intercom installation is necessary. There is no programming required either. This module uses your existing phones and wiring without additional connections.

  • The new design footprint allows the DP29-SW/IM to be mounted in any structured wiring cabinet or even on the wall
  • Jumper 4 allows easy selection between NO (normally open) and NC (normally closed) switches for customized installation
  • S1 Dipswitch allows use of other keypad buttons other than the default (*) key
