6. DEVICE ASSEMBLY
NOTE
During the assembly of dampers and the finishing works, take into account the possibility of
access to the device later and the disassembly of release and control mechanism in order to carry
out the possible service works and technical inspections.
The mcr FID S/… c/P dampers may be installed in the following partitions (walls or ceilings):
masonry walls – concrete with a thickness of at least 110 mm
masonry walls from bricks or blocks at least 115 mm thick
walls from panels at least 125 thick
ceilings of at least 150 mm*
* only for the maximum damper dimension BxH 800x400.
Additionally, dampers can be installed:
outside walls
in dampers sets (multiple damper sets)
The mcr FID S/... c/P shut-off dampers may also be installed in partitions with a lower class of fire resistance. In case
of such an installation, dampers have fire protection equal to the fire protection of the partition, maintaining the smoke
tightness criteria. In the case of installing the damper in a specific type of wall with thickness lower than required,
locally increase its thickness at the circumference of the installed damper, for instance by installing an additional
panel or another construction element.
6.1. INSPECTION BEFORE THE ASSEMBLY
Each damper is inspected before packaging and transporting by the manufacturer. After unpacking at the recipient,
inspect visually in terms of possible deformation of the casing or damper damage during transport.
6.2. FIXING HOLE
The minimum dimensions of the hole which allows correct installation of a rectangular damper is
(B+90)x(H+90) mm.
