The Behnke 20-2480 Loop Module is a functional module for door intercom stations of the Series 20, designed for integration into industrial and professional telecommunication systems. It serves as an indirect hearing aid, transmitting the audio signal via a cable loop using electromagnetic waves. This technology enables barrier-free communication, particularly for individuals with hearing impairments who use an inductive hearing aid. The module is made of acrylic glass and has a square shape with dimensions of 90 mm height and 90 mm width. The module's colour is grey, allowing for discreet integration into existing door intercom systems.

Functions and Equipment in Detail

The module operates as an inductive hearing aid, transmitting the audio signal via a cable loop using electromagnetic waves. This technology is compatible with hearing aids equipped with an inductive loop (T-switch). The transmission occurs without direct electrical connection, ensuring safe and interference-free signal transmission. The module is specifically designed for mounting in door intercom stations of Series 20 and is used as a replacement or supplementary module.

Technology Explained Simply

The functionality is based on electromagnetic induction: the audio signal is converted into electromagnetic waves via an integrated cable loop within the module. These waves can be received by a hearing aid with a T-switch, enabling direct signal transmission to the hearing aid. This allows for clear and interference-free reproduction of the audio signal without requiring additional cables or connections. The acrylic glass material offers high transparency and resistance to mechanical stress and environmental influences.

Compatibility and Accessories

The module is specifically developed for door intercom stations of Series 20 by Telecom Behnke and can be directly integrated into these systems. It is intended as a replacement or supplementary module for existing installations. Compatibility with hearing aids equipped with an inductive loop (T-switch) is guaranteed.

Mounting and Installation

Mounting is performed in the designated module slots of the Series 20 door intercom station. No additional tools or special installation steps are required. Integration is achieved by simply inserting the module into the designated position. The electrical connection is made via the existing connection infrastructure of the door intercom station.

Advantages in Operation

The module provides reliable and interference-free signal transmission for users with hearing aids that use an inductive loop. The use of acrylic glass ensures a robust and durable construction. The grey colour enables discreet integration into existing systems. The module size of 90 x 90 mm fits perfectly into the standard modules of Series 20. The operation without direct electrical connection reduces the risk of interference and increases safety.

Scope of Delivery

The product is delivered as a single module. The scope of delivery includes the Behnke 20-2480 Loop Module.
