DEVICE ASSEMBLY
CAUTION
During the assembly of the damper and installation finish, future access to the device and
removal of the trigger control gear must be considered to enable servicing and inspection.
.
Damper type mcr WIP LD can be installed in the following building partitions:
walls / shafts made of wood with the thickness required for fire resistance
walls / shafts made of concrete with the thickness required for fire resistance
walls / shafts made of bricks or blocks with the thickness required for fire resistance
walls / shafts made of boards with the thickness required for fire resistance
ceilings with the thickness required for fire resistance
Additionally, the dampers can be installed:
outside the partitions (walls)
in modules (sets)
in batteries (sets)
The mcr DOR dampers can also be installed in partitions with a lower fire resistance class. In the case of
such installation, the fire dampers have the fire resistance equal to the fire resistance of the partition, while
maintaining the smoke tightness criterion. When installing a damper in a given type of wall, the thickness
of which is less than required, locally, e.g. by installing an additional board or other construction element,
increase its thickness around the perimeter of the installed damper.

PRE-ASSEMBLY INSPECTION
Each damper is inspected by the manufacturer before packing and transporting. After unpacking at the

damage to the damper during transport.
