Thanks to its clear design language, the MIRO blends harmoniously into its surroundings. The completely smooth surface harmonizes with the soft shapes: the edges are rounded and the intuitively operated buttons are also round (door opener plus 5 buttons for operating additional functions such as stairwell lighting, opening side entrances, internal communication). The ideal combination of quality and practicality.Product features:Hands-free phone MIRO with 5 buttons and door opener button Volume control Call differentiation Hands-free or push to talkTechnical data:Compatible with system 2VOICESupply voltage: 36 - 48V DC (via bus) Dimensions: 110 x 80 x 19mm Plastic ABS whiteInstallation instructions:Note:
