Table 4: Usability
Additional note:
It may also be installed in walls or ceilings of a lower fire resistance class. In this case, however, the fire resistance class of the fire
dampers is reduced accordingly. The conditions listed above must be taken into account.
1)
If mineral wool is used between the fire-resistant dampers, the distance between them is 80 mm.
2)
Distances to the wall or ceiling see Figure 2 on page 7
3)
For wall installation, the smoke detector must always be installed above in the assembly part type EBT with the damper blade axle
in the horizontal position.
4)
When installing in solid ceilings, the dimensions of the fire-resistant dampers BKA-Ü are limited to W and H = 500 mm.
5)
Installation only in combination with a concrete base still to be made on site.
6)
For each
fire-resistant damper, a separate installation opening must be provided.
