The mcr WIP type fire dampers may also be installed in space dividing elements in buildings that have a lower fire- resistance rating. In such cases, fire dampers will have a fire-resistance rating equal to that of a space dividing element, with the condition of smoke leakage rating being satisfied. When installing a fire damper in a given type of wall which is thinner than required, its thickness should be increased along the perimeter of the fire damper, e.g. by installing an additional board or other building element. Fire transfer dampers WIP/T and WIP/T-G are assembly including the fire grille, according to the manufacturer guidelines.6.1.
