Operation on the analogue extension connection of an ICT system from the own or other brands
1 – 4 doorbell buttons (free configurable)
Programming of numbers and functions via app (for iOS and up to Android 13)
Name plate illumination without additional power supply
Indirect lighting (doorbell transformer required)
The TFS-Dialogue 400 with its elegant glass front and indirect lighting sets completely new accents. The door intercom system also sets new standards in terms of functionality. Not only can the number of bell buttons be freely selected from 1 to 4, but a code lock function can also be conveniently implemented with the TFS-Dialogue 400. And the best thing about it is that it can be set up easily from an Android or iOS device using an app*.
The TFS-Dialog 400 is connected directly to an analogue subscriber port on your ICT system by means of a 2-core cable and behaves like a telephone: when the doorbell button is pressed, an internal or external phone number is dialled.
*Smartphones with Android 14 or higher are not supported. The code lock function can therefore only be used via iPhone or Android phone with OS versions 8 to 13.
