The Gira System 106 is an installation system made of real metal with a minimalist and elegant design, without a frame, based on a basic dimension of 106.5 × 106.5 mm. With the modular door station in the Gira System 106, hospitality begins right at the front door. From call button, audio, and camera modules to information and blank modules, all functions present a coherent overall picture. In the dark, the backlit call buttons with labeling fields ensure good readability and an appealing appearance. Individually customizable through its modular design, System 106 can be used in single-family and multi-family homes, as well as in office buildings, industrial properties, and hotels. The modular structure allows the system to be tailored in size, design, and functionality to meet specific needs. Extensions and modifications can be easily made at any time through module exchange. Even a complete front change is possible with the system, allowing the appearance of the installation to be adjusted as well.
