equipment, e.g. a forklift truck.
1. Unpack the damper and place it upright on the
floor. Do not remove the straps yet.
2. Place the U channel sections between the upper-
most blade and the frame.
3. Move the fork carefully underneath the uppermost
blade, then lift it. Put a piece of wood or anything
similar between the blade and the fork so as not to
damage the blade.
Carefully lift the smoke control damper with the
forklift truck and place it in the installation opening.
4. Once you have installed the smoke control
damper, remove the straps; in case of mortar-
based installation, remove the straps only after the
mortar has cured. Remove the corner protectors.
Dispose of the straps and corner protectors.

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 so that the functional reliability
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 64.

⑤On a horizontal smoke extract duct
⑥In a horizontal smoke extract duct
⑦At the end of a horizontal smoke extract duct
⑧EK-JZ as additional supply air inlet
⑨Cover grilles
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 so 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 so that smoke can be extracted.
To ensure the creation of a layer that is nearly free from
smoke, smoke control dampers used as additional
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.
Supply air and smoke extraction in ventilation sys-
tems
When authorised by building authorities or authorised
bodies, smoke extract and supply air applications as
well as ventilation can be enabled in combined systems
with smoke control dampers. Depending on the system
layout, the damper blade can be fully opened, fully
closed or in the intermediate position. Depending on
where the dampers are installed, country-specific regu-
lations may apply to ventilation applications.

The fixing tab is not needed if the installation of the
damper is partly dry and mortarless and there is a screw
connection in the installation gap S1 and S3.
Fixing tab for ceiling slab installation
Before the subframe is mortared in, the fixing tabs on
the damper frame must be bent and spread.

High-temperature sealing tape
Fig. 8: Affix the sealing tape
Affix the high-temperature sealing tape (Fig. 8/1) with
trim panel thickness (flush at front and rear) to the
damper frame (if necessary, mark the trim panel thick-
ness beforehand). Do not glue the ceramic fibre
paper onto the wall or trim.

5.3.2 Fixing points
The frame of the smoke control damper has pre-drilled
connection points that are used to screw-fix the damper
to the wall.
Fig. 9: EK-EU pre-drilled attachment options
1 e.g. concrete screw with countersunk head
2 Threaded bolts with nut and washer M8
Note: The fixing elements must not protrude on the
inside of the damper frame. Contact with the damper
blade will damage the damper blade and the entire
damper will need to be replaced.
Additional fixing points
If the pre-drilled fixing points cannot be used or addi-
tional drilled holes are needed, these must be provided
as follows in the damper frame.
Fig. 10: Create additional fixing options
1 EK-JZ
2 Mineral wool or high-temperature sealing tape
3 Solid shaft wall or solid wall
4 Wallplug with fire safety engineering certification
and threaded bolts M8
5 Washer, nut M8
Number of fixing points
B < 800 mm - 1 fixing point
B ³ 800 mm - 2 fixing points
Note: The fixing elements must not protrude on the
inside of the damper frame. Contact with the damper
blade will damage the damper blade and the entire
damper will need to be replaced.

5.3.3 Adjoined damper installation
Side by side
The vertical frame section opposite the actuator
encasing has markings that indicate where the screw
holes to join dampers have to be drilled. If additional or
alternative fixing points are required, these must be pro-
vided as described under
Ä 5.3.2 ‘Fixing points’
on page 18.
Fig. 11: EK-JZ dampers side by side (left side construc-
tion and right side construction)
1 Dry wall screw 4.5 x 70 mm or 5.0 x 70 mm
2 Hexagon head screw M8 x 90 mm or threaded rod
M8 with washers and nuts
On top of each other
Screws can be set anywhere on the horizontal frame
sections; leave approx. 200 mm between screws,
approx. 40 mm between screws and edges; predrill
holes if necessary. Insert screws both from the top
damper and from the bottom damper; do not insert all
screws in one line, but in an offset pattern.
Fig. 12: EK-JZ dampers on top of each other (right side
construction)
1 Dry wall screw 4.5 x 70 mm or 5.0 x 70 mm
If you need more than two dampers sidy by side or on
top of each other, consult with TROX to determine if this
is technically feasible.

5.4 Solid walls or solid shaft walls
5.4.1 Installation opening
Fig. 13: Ideal installation opening
in
solid wall or shaft wall
on
solid wall, shaft wall or fire-resistant smoke extract
duct
b = [B + 280 mm] + s1 + s2 b = nominal width B
h = [H + 80 mm] + s3 + s4 h = nominal height H
b / h= [nominal size B / H + damper casing] + installation
gap
The installation gap (s) is dependent on the filling mate-
rial used:
Fibre paper: 3-5 mm
Mortar: up to 150 mm
Mineral wool: 10 to 40 mm
Ideally, the installation opening is equal to the nominal
size of the smoke control damper. For installation on a
wall, however, the installation opening may also be
smaller than the nominal size of the damper, for
example, when no damper standard height fits the instal-
lation opening exactly. In such a case you have to make
sure that there is enough clearance to install the
damper.
