Installed in a flush-mounted box, the TFS-Dialog 300 door intercom system lies flat on the wall or door frame and integrates elegantly into the building structure – also as a contemporary replacement for the old "doorbell" system. A two-core cable provides the connection to the ITK system and activates the many technical features. Four variants with one, two, three or four bell buttons are available.
