This product is a function module of the brand Telecom Behnke, manufacturer's number 20-2417, specifically designed for door intercom stations of the Series 20. It is a TK system module, serving as an extension or replacement part for existing systems. The module integrates a piezoelectric button, centrally positioned and intended for operating the door intercom station. Dimensions are 90 mm in height and 90 mm in width, representing a compact and standardized installation size for Series 20.

Applications

The module is intended for use in industrial and commercial telecommunication systems, particularly in door intercom systems that are part of a larger TK system. It is used in areas where mechanical operation via a button surface is required, for example in entrance areas, factory halls, or office buildings. The module is used exclusively in conjunction with door intercom stations of Series 20, with compatibility guaranteed due to specific dimensions and functionality.

Functions and Equipment in Detail

The module features a piezoelectric button, activated by mechanical pressure. Piezoelectric buttons are known for their longevity and low mechanical stress, as they do not have moving parts in the classical sense. The button surface is centrally located within the module, enabling intuitive operation. Dimensions of 90 mm height and 90 mm width correspond to the standard format for Series 20 modules, allowing seamless integration into existing installations.

Technology Explained Simply

The piezoelectric button operates based on the piezoelectric effect: when pressure is applied to the button surface, an electrical voltage is generated, serving as a signal for the door intercom station. This principle ensures reliable and low-maintenance operation, as no mechanical contacts wear out. The module is designed as a TK system module, meaning it integrates into an existing telecommunication system without requiring additional power supply or external control. Connection is made via the existing interface infrastructure of the door intercom station.

Compatibility and Accessories

The module is exclusively designed for door intercom stations of Series 20 by Telecom Behnke. It is not suitable for other series or manufacturers. Compatibility is based on exact dimensions (90 x 90 mm) and the electrical interface, which is standardized for Series 20.

Installation and Mounting

Mounting is performed into the designated cutout of the Series 20 door intercom station. Due to the standardized dimensions of 90 mm height and 90 mm width, installation is simple and precise. No additional tools or mounting aids are required, as the module is directly inserted into the housing. Electrical connection is made via the existing terminals of the door intercom station.

Operational Advantages

The use of the piezoelectric button provides high operational reliability and long service life, as no mechanical contacts wear out. The central positioning of the button surface ensures intuitive operation. The module is compact and fits exactly into the designated modules of Series 20, enabling clean and professional installation. Integration into existing TK systems occurs without additional modifications or external power supply.
