Stainless steel door phone system designed for analogue interfaces – it is not only its design that shines

Universal stainless steel door phone system for flush mounting

Large doorbell buttons, optional use as a light key

Power-saving LED illumination with infinitely variable colour (cool white up to warm yellow)

Programming of phone numbers and basic functions by telephone

Your advantages in detail

This stainless steel door intercom system successfully introduces special design accents to your front door and ensures the highest level of operating convenience. Large push-buttons with integrated energy-saving LED lighting securely guide the visitor to the desired destination. An existing installation can be easily upgraded to the TFS-Dialog 300, thus combining state-of-the-art technology with superior sound quality. Just screw the door intercom system into the flush-mount box. For a new installation, a matching flush-mount box is supplied.

The system is ideally suited for ICT systems without a separate door phone interface because it is directly connected to a free analogue extension. Once the door bell is triggered, the intercom system behaves just like an extension phone and dials a pre-defined number – this can be another extension, a group or even an external number. If you want, the door signal can also trigger a switching operation – e.g. activate the door bell or the staircase lighting.
