4 Parts and function
Smoke control dampers are used in mechanical smoke
extract systems. They are used for extracting smoke
gases and for providing additional supply air to one or
more fire compartments.
Smoke control dampers are made from calcium silicate
boards, and the electric actuator and the optional con-
trol module are encased such that the functional relia-
bility is ensured even in the event of a fire.
Regular maintenance of the smoke control damper is
required to ensure its functional reliability

nance’ on page 38.

⑤Installation on horizontal smoke extract ducts
⑥Installation in horizontal smoke extract ducts
⑦Installation at the end of horizontal smoke extract
ducts
⑧EK-JZ as additional supply air inlet
⑨Cover grille
During normal operation Type EK-JZ smoke control
dampers remain closed. For smoke extract, the smoke
control dampers in the affected fire compartment fully
open such that smoke can be extracted. All other smoke
control dampers remain closed.
In the event of a fire, smoke control dampers that are
used as additional supply air inlets in the affected fire
compartment also open such that smoke can be
extracted. To ensure the creation of a layer that is nearly
free from smoke, smoke control dampers used as addi-
tional supply air inlets should be installed near the
ground.
The control input signal for the actuator may come from
a duct smoke detector or from the central fire alarm
system. Using cables with specific circuit integrity for the
supply voltage ensures that the actuator is supplied with
voltage even in the event of a fire and hence that its
function and the communication are maintained.
Ventilation
During ventilation operation the smoke control dampers
of the smoke extract system remain fully open. Smoke
control dampers which are used as additional supply air
inlets remain closed during ventilation operation.
Depending on where the dampers are installed, country-
specific regulations may apply to ventilation applica-
tions.

Installation
1. Create an installation opening according to Fig. 8. The installation opening has to be rectangular, with smooth
surfaces (± 5 mm).
If the surfaces are not smooth, use mortar to make them smooth.
Place mineral wool along the left side (vertical), approx. 20 to 40 mm thick.
2. Glue one strip or two parallel strips of ceramic fibre paper (Fig. 8/5) to the underside of the damper frame such
that the edges of paper are flush with the edges of the damper frame,
Ä 15.
3. Place the smoke control damper with the ceramic fibre paper in the installation opening and press it towards
the mineral wool on the left. Make sure that the damper is vertical; use wedges to hold the damper in the cor-
rect position; the damper has to be installed without torsion (check the diagonal length; allowed tolerance:
2 mm).
Install the damper such that the operating side is flush with the wall (A-A section).
4. Fill the installation gap on the right with mineral wool. If the gap is wider than 40 mm, it has to be filled with
mortar. Fill the gap with mortar, ideally until it is as thick as the wall, but at least 100 mm.
Fill the installation gap at the top with mineral wool. Note: Do not use mortar for the gap at the top.
Do not leave any gaps or spaces between the damper and the wall. If you have used any objects to facilitate
damper installation, e.g. wedges, remove them now. Fill any remaining hollow spaces with mineral wool or
mortar.
5.
CAUTION!
Malfunction of the smoke control damper
Use only the fixing points marked on the damper frame (drilled hole, indentations) to screw fix the smoke
control damper. Do not use any screws anywhere else on the damper frame as they may prevent the
blades from closing properly. Fixing points on the H section only from H ≥ 1230 mm.
Drill screw holes at the fixing points marked on the damper frame (Fig. 8/6), then screw fix the damper to the
wall. Be careful when you tighten the screws; do not exercise any tension as this may damage the damper.

Materials:
Mineral wool
Ä ‘Mineral wool as filling material’ on page 15
Ceramic fibre paper
Ä ‘Ceramic fibre paper’ on page 15
Mortar
Ä ‘Mortars for mortar-based installation’ on page 15
Fire-resistant screws (with suitability certificate)
Requirements:
Solid walls made of, for example, concrete, aerated concrete or masonry, gross density ≥ 500 kg/m³ and
W ≥ 100 mm
≥ 40 mm distance to load-bearing structural elements
≥ 200 mm distance between two smoke control dampers
Installation
1. Create an installation opening according to Fig. 9. The installation opening has to be rectangular, with smooth
surfaces (± 5 mm).
If the surfaces are not smooth, use mortar to make them smooth.
Place mineral wool along the left side (vertical), approx. 20 to 40 mm thick.
2. Glue one strip or two parallel strips of ceramic fibre paper (Fig. 8/5) to the underside of the damper frame such
that the edges of paper are flush with the edges of the damper frame,
Ä 15.
3. Place the smoke control damper with the ceramic fibre paper in the installation opening and press it towards
the mineral wool on the left. Make sure that the damper is vertical; use wedges to hold the damper in the cor-
rect position; the damper has to be installed without torsion (check the diagonal length; allowed tolerance:
2 mm).
Install the damper such that the operating side is flush with the wall (A-A section).
4. Fill the installation gap on the right with mineral wool. If the gap is wider than 40 mm, it has to be filled with
mortar. Fill the gap with mortar, ideally until it is as thick as the wall, but at least 100 mm.
Fill the installation gap at the top with mineral wool. Note: Do not use mortar for the gap at the top.
Do not leave any gaps or spaces between the damper and the wall. If you have used any objects to facilitate
damper installation, e.g. wedges, remove them now. Fill any remaining hollow spaces with mineral wool or
mortar.
5.
CAUTION!
Malfunction of the smoke control damper
Use only the fixing points marked on the damper frame (drilled hole, indentations) (Fig. 9/6) to screw fix the
smoke control damper. Do not use any screws anywhere else on the damper frame as they may prevent
the blades from closing properly. Fixing points on the H section only from H ≥ 1230 mm.
Drill screw holes at the fixing points marked on the frame (Fig. 9/6), then screw fix the frame to the wall. Be
careful when you tighten the screws; do not exercise any tension as this may damage the damper.
6. Connect a smoke extract duct made of calcium silicate to the installation side of the damper (Fig. 9/8),
Ä 6 ‘Connecting the smoke extract duct’ on page 31.
Connect a smoke extract duct made of calcium silicate or sheet steel to the operating side of the damper
Ä 6 ‘Connecting the smoke extract duct’ on page 31. If the operating side is not connected to a duct, a cover
grille is required
Ä 6.2 ‘Cover grille’ on page 32.
