The performance classes of the fire damper and the wall or ceiling may differ. The lower performance class determines the performance class of the overall system. Fire dampers with stainless steel casing (FKRS-EU-2/... version) have a performance class up to EI 90 S for all subsequent applications due to an update of EN 15882.
