At popular request. The extra-flat presence detector IR Quattro Slim XS virtually disappears into the wall or ceiling. Thanks to the new and practical flush-mount box format, it forms a strikingly unobtrusive symbiosis with the living environment and can now be installed in any standard flush-mount box. In short: Our flattest presence detector acts as if it is not there at all – yet it is absolutely present when it matters. To be prepared for all situations, the Slim XS is also available in a round design.
