For this type of multiple installation FK90K fire dampers generally must be
connected with flexible connectors.

FK90K fire dampers on adjacent walls or ceilings must lie flush against the
surface. Unevenness must be smoothed out with plaster or compensated for
with fillings F1.

are approx. 6 mm thick resilient, non-combustible mineral sealants with a
melting point of
≥
1000°C, e.g. 100-mm-wide strips made of calcium-mag-
nesium silicate (

). Mineral wool can also be used and must
have a density of
≥
80 kg/m³ when compressed.
•
must be used between FK90K fire dampers when installing multiple fire
dampers or for assembly with FK90K connectors and to act as a seal
between the FK90K fire dampers and adjacent ceilings.
•
can be used as compensating elements and/or to provide a seal between
FK90K fire dampers and adjacent walls, if the walls are not sufficiently level.
