Auerswald TFE / TFS Dialog 312

Auerswald’s stainless steel door intercom system adds a touch of style to your door. Large buttons with integrated, energy-saving LED lighting guide visitors safely to their desired destination. An existing Auerswald installation can be easily upgraded to the TFS-Dialog 300, bringing it up to the latest state-of-the-art technology with excellent sound quality. The door intercom system is simply screwed onto the existing flush-mounted box. For new installations, a matching flush-mounted box is included. The system is ideal for telephone systems without a separate door intercom interface, as it connects directly to a free analog extension port on the system. When a doorbell button is pressed, the door intercom system behaves like an extension phone and dials a pre-programmed number—another extension, a group, or even an external destination. Simultaneously with this “door call,” a switching operation can also be triggered
