Your advantages in detail

The TFS-Dialog 400 door terminal system with its elegant glass panel and indirect lighting isn’t just attractive – it also sets new standards in functionality. The number of doorbell buttons can be set from 1 to 4 and the TFS-Dialog 400 even offers a convenient code lock function. Best of all, the system is easy to configure using an app from an Android or iOS device.

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.
