This product is a function module for door intercom stations of series 20, manufactured by Telecom Behnke. It is a module with an integrated LC display and touch functionality, designed to be installed in existing door intercom systems of series 20 to extend their functionality. The module enables visual and interactive control of calls, menu functions, and other operating options directly at the door intercom station.

Applications
This module is specifically designed for use in industrial and commercial environments where robust and user-friendly operation of door intercom systems is required. It is suitable for installation in door intercom stations that are already part of a telecommunication system, enabling adaptation of the user interface to specific requirements, such as direct call connections to specific rooms or persons, telephone directory access, or logo display.

Functions and Equipment in Detail
The module features a resistive touch display with a diagonal of 3.5 inches. The surface is made of aluminium, providing high mechanical stability and resistance to mechanical stress. The display functions are freely configurable, allowing various direct call buttons, keypad blocks, telephone directory functions, or logo displays depending on the application. Configuration is performed via the central telecommunication system, enabling flexible adaptation to different usage scenarios.

Technology Explained Simply
A resistive touch display responds to pressure, allowing operation even with gloves or a stylus. The 3.5-inch display provides sufficient space for clear symbols and text, enabling operation even in low light conditions or from a certain distance. The aluminium casing ensures a robust and long-lasting construction that integrates well into industrial environments. The free configurability of functions allows customised use without requiring additional hardware.

Compatibility and Accessories
The module is specifically developed for door intercom stations of series 20 by Telecom Behnke and is integrated into these systems. It is not a standalone device but complements existing door intercom stations. Compatibility is limited to series 20; use in other systems is not intended.

Mounting and Installation
Installation is performed by inserting the module into the existing door intercom station of series 20. No additional software or external control unit is required, as configuration is done via the central telecommunication system.

Advantages in Operation
The free configurability of functions allows the module to be adapted to specific requirements, increasing efficiency and user-friendliness. The robust aluminium construction ensures a long service life, even under demanding conditions. The integrated touch technology enables intuitive operation accessible even to users without technical expertise.
