Our flattest presence detector. Now even smaller in a flush-mounted box format. By popular demand. The extra-flat presence detector IR Quattro SLIM XS almost disappears into the wall or ceiling. Thanks to the new and practical flush-mounted box format, it forms a strikingly unobtrusive symbiosis with the living environment and can now be installed in any standard flush-mounted box. In short: Our flattest presence detector acts as if it is not there at all – yet it is absolutely present when it matters.
