  • The IST RETRO Doorbell Adapter is an add-on control board for the IST RETRO Intercom System that allows you to connect your existing 2-wire doorbell button to the system, instead of the standard 4-wire button. When the doorbell button is pressed, your IST RETRO room stations will chime. The control board installs behind your IST RETRO Master Station. The doorbell's two wires connect to the board and the board's 3-wire adapter cord connects to the master station's door station input.
