Intelligent door communication for every home

The Auerswald TFS-Dialog 312 is an analog door intercom system designed for direct connection to an a/b extension of your telephone system. It is ideally suited for private use or small commercial applications and enables comfortable door communication with up to four doorbell buttons. The high-quality construction ensures a long lifespan, even in adverse weather conditions.

Flexible, robust, and easy to integrate
Thanks to its compact design, the TFS-Dialog 312 can be mounted both on the surface and flush. Installation is straightforward, and programming is conveniently done via a connected telephone. The illuminated doorbell buttons enhance visibility in the dark, while the clear voice transmission ensures communication without misunderstandings.

Varied control functions and expandability
In addition to voice communication, the system also allows for the control of door openers, lights, and external chimes directly through programmable switching functions. The system can be optionally expanded with an a/b switching module, making it well-prepared for future requirements.
