Expanded and extended DIBt approval

Approved until 2021 as a smoke trigger device: the Duct Smoke Detector KRM^®. In many discussions the subject comes up: the ECOJ decision and CE marking. Currently, many substantial changes are in the works which relate to this subject in the area of building law. Unfortunately, mistakes in interpretation continue to circulate.

The fact is that wherever harmonized product standards exist and the transition period has elapsed, no supplementary national requirements regarding a construction product can be issued. This also means, however, that in a place where no harmonized standard exists, or where a product does not even fall under a harmonized European standard, a product’s fitness for use must be otherwise demonstrated. Here, the current appropriate and legally secure evidence of fitness for use is still the general-type approval of the building supervisory authorities. In the case of our duct smoke detector KRM in the DZ version as a smoke trigger device, this approval has now been extended to 2021 and expanded to new models.
