Installation alternatives outside the wall
To prevent sleeve joints between the damper and the duct in the wall, the damper can alternatively be placed
outside the wall in the flow of the approved smoke extract duct
5.6 ‘Fire-resistant smoke extract ducts’
1.
Create an installation opening according to Fig. 10.
Installation opening b x h:
b = B + 100 + 2s
h = H + 100 + 2s
s ≤ 60 mm (leave enough space for mortaring of the gap)
Example:
B x H = 1200 x 750 mm, s = 50 and 60 mm
b = 1200 + 100 + (2 x 50) = 1400 mm
h = 750 + 100 + (2 x 60) = 970 mm
2.
Push the smoke control damper into the installation opening and secure it. Make sure that the actuator
encasing rests on the face of the wall.
3.
Close off the perimeter gap »s« with mortar. The mortar bed depth must be at least 100 mm.
