Auerswald TFE / TFS Dialog 312

The stainless steel door intercom system from Auerswald brings a stylish touch to any entrance. Visitors are guided reliably to the right destination thanks to the large buttons with built-in, energy-saving LED illumination. Existing Auerswald installations can be upgraded with ease to the TFS-Dialog 300, updating them to the latest technology with outstanding sound quality. Fitting the door intercom system is a simple matter of screwing it onto the existing flush-mounted box. A compatible flush-mounted box is supplied for new installations. The system is perfect for telephone systems that lack a dedicated door intercom interface, since it connects straight to a free analogue extension port on the telephone system. On pressing a doorbell button, the door intercom system acts like an extension telephone and dials a pre-programmed number—whether another extension, a group or even an external destination. At the same time as this “door call,” a switching operation can also be triggered.
