4. DEVICE DESIGN AND PRINCIPLE OF OPERATION
Design
The single-plane dampers mcr FID S/… c/P are made of an enclosure with a rectangular cross-section, a portable
shut-off partition and a release and control mechanism activated manually or automatically after the thermal release
is activated. The damper enclosure is made of a steel, galvanised steel sheet, or a stainless steel one. In the damper
enclosure, on its circumference, the insulation perforation with the relevant width is performed. The shut-off partition
of dampers is made of a non-flammable plate and is set in a sheet reinforcement profile. On the enclosure, in the
