Installation into combined penetration seal
Mixed installation of fire dampers FK-EU and FKRS-
EU together with cables and tubes in a fire batt
system: Hilti-CFS-CT, CP 670 and CP 673.
Installation is in solid walls, lightweight partition
walls with metal or timber support structure and
solid wood / cross-laminated timber.

H1 = 3000
×
2000 mm.
The penetration seal size depends on the configura-
tion, see the separate installation and operating
manual for the combined penetration seal.
The minimum distance between the casings of the
FKRS-EU is
≥
40 mm.
The minimum distance between fire damper casing
and cable penetrations is
≥
100 mm.
The minimum distance between fire damper casing
and pipe penetrations is
≥
50 mm.
Distance from FKRS-EU to fire dampers FK-EU
≥
50 mm.
The position of the fire dampers, tubes and cable in
the combined penetration seal is irrelevant, but must
comply with the specified minimum distances.
Fire dampers, cable, cable bundles, cable trays,
conduits and plastic pipes can be laid individually or
in multiples.
The fire dampers must be suspended on both sides,
