The product is a module for elevator emergency call systems, manufactured by Telecom Behnke, with the manufacturer's number 20-3115. It serves as an operating and communication element in elevator installations, enabling a connection to the maintenance service or emergency call center in case of an emergency. The module is made in an aluminium version, ensuring a robust and durable construction for use in technical installations.

Applications
This module is specifically designed for use in elevator installations, where reliable and fast emergency call functionality is required. It is mounted in elevator cabins to enable direct communication with the operator or an emergency call center in case of a malfunction or emergency. Its use in public or commercial buildings, where elevator emergency call systems are mandatory, is typical.

Functions and Equipment in Detail
The module features an integrated microphone located at the lower part of the device to enable voice transmission. Additionally, a single button with the label Aufzugnotruf and a bell symbol is positioned at the upper part. This button serves as the trigger for the emergency call and is illuminated, ensuring better visibility in dark or poorly lit environments. The illumination enhances the button's recognizability, especially in emergency situations.

Technology Explained Simply
The design of the module takes into account the requirements for safety and reliability in elevator installations. The microphone enables voice transmission over the network, allowing the user to describe their location and the emergency. The illuminated button ensures that the emergency call function can be quickly identified and used even with limited visibility. The aluminium construction provides mechanical stability and resistance to wear, which is important for use in technical environments.

Compatibility and Accessories
The module is designed as a single component for elevator emergency call systems and is used in conjunction with a corresponding network or communication module. It is not designed as a standalone device for communication, but as part of a larger system that establishes the connection to the emergency call receiver. The exact compatibility with other system components is documented in the manufacturers' technical documentation.

Mounting and Installation
Installation typically takes place on the interior side of the elevator cabin, in an easily accessible position. The installation requires connecting the module to the existing emergency call system, with electrical connections carried out according to technical specifications.

Advantages in Operation
The module offers clear and intuitive operation through its distinct labeling and bell symbol. The illuminated button increases recognizability, which can reduce response time in emergencies. The robust aluminium construction ensures a long service life and resistance to mechanical stress. Integration into existing elevator emergency call systems enables fast and reliable communication in emergencies.
