With its stainless-steel door entry system, Auerswald presents a stylish new design. Visitors are safely guided by the system’s extralarge buttons with integrated power-saving LED lighting. Adapting an existing Auerswald installation for the TFS-Dialog 300 requires very little effort – and ensures you have the latest technology. You simply screw the door entry system to the flush-mounting box. If yours is a new installation, the appropriate flush-mounting box is included with the system.

The highlights of TFS-Dialog 300:

• Operation on an analog subscriber port of a PBX system
  made by Auerswald or other vendors
• 1–4 door bell buttons (TFS-Dialog 301, ...302, ...303, ...304),
  optionally useable as light key
• Telephone numbers and basic functions can be programmed via an extension telephone
• Two levels of sensitivity for noisy and quiet environments
• Excellent speech audibility, frequency-optimised amplifier electronics
• Integrated switching contact for door opener, doorbell or light (doorbell transformer required)
• Power saving, maintenance-free LED lighting,
  continuously adjustable colour (cool white up to warm yellow)
• Additional switching possibilities with a/b Switching Modules
   

Exklusive by  Auerswald: the a/b Switching Modules

Auerswald's a/b switch modules are made especially for TFS-Dialog 300. They can be connected any- where on the a/b line between the door entry and PBX systems, allowing you to use an existing doorbell or to switch on the stairway light.

Up to six a/b switch modules per TFS-Dialog 300 can be used with only one 2-wire cable. Each button can be assigned to and control one or several switch modules. Without problems, the modules fit in any of the existing flush-mounting junction boxes.

Communication and switching using mobile phones

Quite often you are away from home only for some quick errands. If the door call is forwarded to your mobile phone you can tell the person in front of the door that you will be home in a minute. Or you can tell the postman whom he should hand out the parcel. Is it a family member who has forgotten his key you can even open the door for him and switch on the light. Or you can activate other switching tasks using connected a/b switching modules.
