TFS-D201 AB-Doorphone with 1 button

Even if your phone does not have a TFE-interface - the TFS-Dialog 200 with its timeless design can ensure that you have maximum ease of operation. It is connected via a two-wire cable directly to an A / B port of your system and behaves just like a phone number: If a key "bubble" is pressed, the door intercom system and selects a preset, internal or external number. From your phone, you can talk to the visitor - excellent sound quality thanks to the high-quality micro-electronics - and the door can be opened. And white LED backlight provides in the dark for more brightly illuminated nameplates.
