Auerswald TFS-Dialog 211 Aluminium interphone mural filaire IP22

The Auerswald TFS-Dialog 211 Aluminium Wired Wall Intercom IP22 is a compact, wall-mounted intercom unit designed for fixed installations. Constructed with an aluminium front plate and a slim profile, it provides a durable interface for voice communication in residential and light commercial settings. The device offers protection against solid objects and dripping water with its IP22 rating and fits into narrow mounting spaces thanks to its 104 mm width and 16 mm depth while standing 153 mm tall.

Advantages

The aluminium housing combines strength and corrosion resistance while keeping the unit lightweight. The wired connection ensures stable audio transmission without reliance on wireless networks, and the IP22 protection rating helps protect internal components from accidental contact and vertical dripping water. Its compact dimensions allow installation in confined wall cavities or in-line with other wall-mounted devices.
