Support

Further information

Please note:

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.

We offer the direct download of the installation file (APK) here.
Depending on the Android version and manufacturer / type of Android smartphone, the installation can either be started by clicking directly on the downloaded file on the smartphone (here the release for installation must be confirmed during installation) or the option for "Unknown origin" (or "Unknown sources") must be activated in advance under the general settings under "Security". The file can then be installed by clicking on it.

The TFS Set app is used to program the TFS-Dialog 400 door intercom very easily and conveniently. After the settings have been made in the app, the data is transmitted acoustically to the door intercom. To do this, the loudspeaker of the smartphone is held in front of the microphone of the door intercom. As an alternative to the device loudspeaker, the earpiece of a connected headset can also be used for data transmission. A successful data transmission is visually acknowledged by the intercom.
