Note on combined installation:
Total fire damper surface area ≤ 1.2 m².
The number of fire dampers in an installation opening is limited by their size (B × H for FK2-EU and /or
Æ nominal width for FKR-EU) and the overall area of the fire dampers (1.2 m²).
Alternative installation orientations of side-by-side possible. Details are available upon request.
For installation details FK2-EU, see the installation and operating manual for this fire damper type.
Structural properties of the ceiling construction, including the attachment to the mortar/concrete or any required
reinforcement, have to be evaluated and ensured by others.
Distance of FKR-EU to a FK-EU 75 – 225 mm (flange construction 80 – 225 mm)
