This product is a function module for door intercom stations of series 20, manufactured by Telecom Behnke, with manufacturer's number 20-2031-BS. It serves as an extension or replacement module for existing door intercom systems and enables the integration of three doorbell buttons into the installation. The module is specifically designed for electronic configurations that do not use flat ribbon cables and offers a robust, aesthetically pleasing surface made of aluminium in V2A design. The buttons and the labelling field are illuminated, ensuring good visibility even in poor lighting conditions. The module's colour is silver, and its dimensions are 90 mm in height and 90 mm in width.

Applications

The module is designed for use in industrial and commercial environments where reliable and long-lasting door intercom technology is required. It is particularly suitable for buildings with multiple entrances, where clear assignment of doorbell buttons to individual apartments or offices is necessary. Use in outdoor areas is possible due to the aluminium housing and illumination features, although no specific protection rating (e.g. IP) is mentioned indicating weather resistance.

Functions and Equipment in Detail

The module features three illuminated doorbell buttons, each of which can be assigned to a specific recipient. The illumination of the buttons and the labelling field ensures good recognisability, especially in dark or poorly lit areas. The labelling fields allow for individual identification of the buttons, e.g. with names or room designations. The housing is made of aluminium, manufactured in V2A design, providing high mechanical stability and corrosion resistance. The number of doorbell buttons is exactly three, which represents the maximum number for this module.

Technology Explained Simply

The illumination of the buttons and the labelling field is achieved through integrated light sources, powered by the electrical supply of the door intercom station. The power supply is provided via the existing installation, with no additional power sources or batteries required. This is particularly relevant for older or special installations where the use of flat ribbon cables is not possible or desired.

Compatibility and Accessories

The module is specifically developed for door intercom stations of series 20 by Telecom Behnke and can only be used in conjunction with compatible electronic modules of this series. It is not intended for other manufacturers or series. Use requires an existing door intercom system that supports electrical supply and signal transmission via separate cables.

Installation and Mounting

Mounting is carried out on the existing door intercom station of series 20. The module is inserted into the designated mounting opening and mechanically secured. The electrical connection is made via the existing cables, with attention to the wiring diagram of the installation. No specific tool requirements or additional mounting aids are mentioned. Installation requires basic knowledge of electrical installation and compliance with electrical safety regulations.

Advantages in Operation

The illumination of the buttons and labelling fields improves user-friendliness, especially in poorly lit areas. The aluminium housing in V2A design provides high mechanical stability and is resistant to external influences such as scratches or corrosion. The clear assignment of the three buttons enables efficient use in multi-family houses or office buildings. Compatibility with existing systems of series 20 reduces replacement and installation effort.
