Smoke control damper Type EK2-EU 11

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 54 .

⑤On a horizontal smoke extract duct
⑥In a horizontal smoke extract duct
⑦At the end of a horizontal smoke extract duct
⑧EK2-EU as additional supply air inlet
⑨Cover grilles
During normal operation, Type EK2-EU smoke control
dampers remain closed. For smoke extract, the smoke
control dampers in the affected fire compartment 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.

5 Installation
5.1 Installation situations
The overview of all possible installation types of the
smoke control damper EK2-EU are listed in the declara-
tion of performance; they can be downloaded from the
TROX homepage.
5.2 Safety notes regarding installation
Sharp edges, sharp corners and thin sheet metal
parts
CAUTION!
Danger of injury from sharp edges, sharp cor-
ners and thin sheet metal parts!
Sharp edges, sharp corners and thin sheet metal
parts may cause cuts or grazes.
– Be careful when carrying out any work.
–Wear protective gloves, safety shoes and a hard
hat.
5.3 General installation information
NOTICE!
Be careful to not damage the smoke control
damper
– Protect the smoke control damper from contami-
nation and damage.
–Cover the flange openings and the actuator (e.g.
with plastic) to protect them from mortar and
dripping water.
Please note:
Smoke control damper and electric actuator
(encasing) must remain accessible for maintenance.
Make sure that no loads are imposed on the casing
as this may impair the function of the smoke control
damper.
Install the smoke control damper without torsion
(horizontal/vertical).
Mortar-based installation: The perimeter
gap »s« must be large enough so that mortar can be
filled in even in case of thicker walls.
Requirements for wall and ceiling systems
EK2-EU smoke control dampers may be installed in wall
and ceiling systems if these walls and ceilings have
been erected in compliance with the relevant regula-
tions and according to the manufacturers' instructions,
and if the information on the respective installation sit-
uation applies and the following requirements are met.
Provide any installation openings according to the
installation details in this manual.
Solid walls or solid shaft walls
Solid walls or solid shaft walls made of, for example,
concrete, aerated concrete or bricks, gross density
≥ 500 kg/m³.
Wall thickness W ≥ 100 mm.
Provide each installation opening according to the
local and structural conditions and with regard to the
dimensions of the smoke control damper.
Solid ceiling slabs
Solid ceiling slabs without open spaces, made of
concrete or aerated concrete, gross density
≥ 500 kg/m³.
Ceiling thickness D ≥ 150 mm.
Provide each installation opening according to the
local and structural conditions and with regard to the
dimensions of the smoke control damper.
Lightweight partition walls with metal support struc-
ture
Lightweight partition wall with metal support or steel
support structure, with European classification to
EN 13501-2 or equivalent national classification.
Cladding on both ends made from plasterboard fire
barriers.
Wall thickness W ≥ 100 mm.
≤ 625 mm distance between metal studs.
Create an installation opening with studs.
If necessary, provide trim panels and screw-fix them
to the support structure.
Additional layers of cladding (if stated in the usability
certificate for the wall) and double stud construc-
tions are approved.
Connect the metal sections near the installation
opening according to the installation details in this
manual.
Acceptable mortars for mortar-based installation
In case of mortar-based installation, the open spaces
between the fire damper casing and the wall or ceiling
slab must be closed off with mortar. Entrapped air is to
be avoided. The mortar bed depth should be equal to
the thickness of the wall but must be at least 100 mm.
The following mortars are acceptable:
DIN 1053: Groups II, IIa, III, IIIa; fire protection
mortar of groups II, III
EN 998-2: Classes M 2.5 to M 10 or fire protection
mortar of classes M 2.5 to M 10
Equivalent mortars that meet the requirements of
the above standards, gypsum mortar or concrete

Personnel:
Specialist personnel
Materials:
High-temperature sealing tape
Ä ‘High-temperature sealing tape’ on page 14
For annular gap cover: PROMATECT®-H fire protection board d = 25 mm or strips of plasterboard 2 x 12.5 mm x
45 mm
Steel staples 63/11.2/1.53 mm
Fire protection acrylic
Requirements:
Solid walls,
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
Ä 5.7 ‘Fire-resistant smoke extract ducts’
on page 31 .
Create an appropriate opening
1. Create an installation opening according to Fig. 12 .
Installation opening b x h:
b = B + 100 + s1 + s2
h = H + 100 + s3 + s4
Example: B x H = 1200 x 750 mm, s1 = 5 mm, s2 = 5 mm, S3 = 10 mm, s4 = 3 mm
b = 1200 + 100 + (5 + 5 mm) = 1310 mm
h = 750 + 100 + (10 + 3 mm) = 863 mm
2.
In case of installation variant b, c, d
Stick the high-temperature sealing tape on the damper housing in the trim panel thickness on the damper
housing,
Þ detail 4, Ä ‘High-temperature sealing tape’ on page 14
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 or freely positioned up to a total length L 1/2, centred in the wall.
3. Create the installation gap "s" according to the installation variant; see the table above.
Making the annular gap cover Þ detail 5 + 6
Before fitting the annular gap cover, seal the installation gap with fire protection acrylic on both sides of the
wall. Fix the annular gap cover to the damper casing on both sides of the wall with steel wire clips.
