Installation:
ve d in and on horizontal smoke extraction ducts.
ho d in and on vertical smoke extraction ducts.
ve w in rigid walls and in flexible walls.
ho w in rigid ceilings.
i ↔ o Fire exposure has been verified on both sides.
• S1500 For smoke extraction systems with operating pressures
between 1500 Pa negative pressure and 500 Pa overpres-
sure (pressure class 3). Smokeproof at up to 1500 Pa differ-
ential pressure.
• Cmod For systems designed only for smoke extraction and also for
combined ventilation systems that was as heating, ventila-
tion and air conditioning systems.Intermediate damper blade
positions for volume flow adjustment are permitted (modula-
tion mode).
The service life is verified by 20,000 weight-loaded cycles.
• HOT The smoke control dampers close and open again at least
after 30 minutes of fire exposure at 400°C.
• MA Closed smoke control dampers can be opened after 25 min-
utes of full exposure to fire (> 800°C).
• multi The smoke control dampers may be used between fire com-
partments (multi) and in individual areas (single).
Maintenance-free
EK90 smoke control dampers EN 12101-8 – Series EK92 –
With casing and damper blades made from abrasion-proof, safe,
corrosion-resistant calcium silicate that is suitable for higher
temperatures. The edge protection profiles are made from gal-
vanized steel and include connection holes.
Opening and closing is carried out by means of stainless steel
shafts using electric motor drives for 24 V AC/DC or 230 V AC
even when the fan is running and at inflow velocities of up to
20 m/s.
Special seals without any additional stops allow for large free
cross-sections and thus extremely low pressure drops and
sound power levels.
Widths B: 200 mm to 1500 mm
Heights H:: 200 mm to 800 mm
Lengths L: 350 mm to 850 mm
All dimensions are available in 5-mm
increments!
Installation with horizontal or vertical damper
blade:
• in rigid walls and ceilings, ≥100 mm thick and
≥ 450 kg/m³ bulk density.Wet installation with
mortar or a dry installation with mineral wool
≥ 100 kg/m³ are possible.
• in metal stud walls, ≥95 mm thick, with or with-
out mineral wool ≤ 100 kg/m³ inside.
• on and between horizontal or vertical smoke
extraction ducts.
Can be connected:
• in single or double-sided arrangement on
smoke extraction ducts with fire resistance
period,
• in single-sided arrangement on smoke extrac-
tion ducts without fire resistance period,
• in single or double-sided arrangement on pro-
tective grille

Data sheet
Calculating damper blade excess lengths:
•Ü1 = ½ · H - L1 + 105 mm; Ü2 = ½ · H - L2 - 107 mm
• If Ü1 ≤0 or Ü2 ≤0, there is no damper blade excess length!
If protective grilles are mounted directly on the casings,
then Ü1 or Ü2 should be at least -20 mm, which equates to a
20-mm freedom of movement. Hence, L1 ≥½ · H + 125 mm and
L2 ≥½ · H - 87 mm should be applied!
L2 ≥W(D) + Z is also necessary! Here, W= thickness of the wall,
D = thickness of the ceiling. Zis the necessary casing excess
length.

With inflow velocities vA Max = 10 to 20 m/s, depending on the width and height of the EK90 smoke control damper,
the inflow velocity limits the opening of the smoke control damper. It may need to be reduced temporarily!

EK90 smoke control dampers
Installation in rigid walls and ceilings (1) General
The installation in rigid walls and ceilings from a thickness of 100 mm is performed as wet installation using mortar.
Gaps of up to 25 mm in width can also be filled with mineral wool ≥100 kg/m³ and ≥1000°C melting point. Shear pro-
tection brackets A protect installation at the rear. Alternatively, shear protection brackets B can be used, especially if
the installation openings are only accessible from the front, i.e. from the drive side, such as is the case with shaft walls.
Suspended installation in ceilings (motor drive underneath the ceiling)
Vertical installation in ceilings (motor drive above ceiling)
All dimensions in mm
Installation in rigid walls and ceilings
•Outer dimensions of the smoke control dampers in the installa-
tion area of the wall or ceiling: (B + 100 mm) x (H + 100 mm).
• Installation opening in rigid walls and ceilingsb x h = (B +
100 mm + 2 · s [mm]) x (H + 100 mm + 2 · s [mm])
• Mortar gap for wet installation s ≥25 mm.
• Gap for mineral wool filling s = 10 to 25 mm.
• Calcium silicate support bearings with the dimensions 100 mm
x 100 mm x 25 mm for gaps s = 25 mm are included in delivery.
Support bearings must always be used as supports when
performing dry installation with mineral wool in walls, and as
centring devices in ceilings. In other circumstances, support
bearings can be used as installation aids, except in metal stud
walls.

• Spacing DA ≥180 mm:
Shear protection brackets A and B can
also be used above, below and laterally;
and combined as A and B.
⇒see page 19
• Spacing DA ≥125 mm up to ≤180 mm:
Shear protection brackets A can be used
laterally, and shear protection brackets B
above and below.
• Spacing DA = 22 mm:
Shear protection brackets A or B
can be used laterally.
• Spacing DA ≥52 mm up to ≤125 mm:
Shear protection brackets A or B can
be used laterally.
Depending on the spacing DA, thick
filling strips from 25 to 75 mm, made
from calcium silicate boards, are
required with approx. ≥500 kg/m³ bulk
thickness.
They should be fastened to the ceiling
with screws or bolts with a diameter of
5 mm or more.
