4. DESIGN AND OPERATING PRINCIPLE OF THE FIRE DAMPER
Design
The mcr FID PRO single-plane fire dampers consist of a housing with a round cross section, movable cut-off partition
as well as a release and control mechanism which is started remotely or automatically (after a thermal release has
been actuated). Fire dampers’ housings are made of galvanised steel sheet or stainless steel sheet. In the fire
damper’ housing, along its perimeter, there is an insulation perforation of suitable width. The fire damper’s cut-off
partition is made of non-flammable board. The partition is lined on both sides with sheet metal reinforcement. On the
