Parts and function
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 control module are encased such 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

Cover 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. T
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.
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, countryspecific regulations may apply to ventilation applications.

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 (
that the edges of paper are flush with the edges of the damper frame,
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 correct 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
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.

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 (
that the edges of paper are flush with the edges of the damper frame,
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 correct 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
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.

the blades from closing properly
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.

General safety notes
DANGER!
Danger of electric shock! Do not touch any live components! Electrical equipment carries a dangerous
electrical voltage.
– Only skilled qualified electricians are allowed to
work on the electrical system.
– Switch off the power supply before working on
any electrical equipment.
CAUTION!
Danger due to inadvertently actuating the smoke
control damper. Inadvertent actuation of the damper
blade or other parts can lead to injuries.
Make sure that the damper blade cannot be released
inadvertently.
Regular care and maintenance ensure operational readiness, functional reliability, and long service life of the
smoke control dampers.
The owner or operator of the system is responsible for
the maintenance of the smoke control damper. The
operator is responsible for creating a maintenance plan,
for defining the maintenance objectives, and for the
functional reliability of the damper
Functional test
The functional reliability of the smoke control damper
must be tested at least every six months; this has to be
arranged by the system owner. If two consecutive tests,
one 6 months after the other, are successful, the next
test can be conducted one year later.
The functional test must be carried out in compliance
with the basic maintenance principles of the following
standards:
.
Maintenance
The smoke control damper and the actuator are maintenance-free with regard to wear but smoke control
dampers must still be included in the regular cleaning of
the smoke extract system.
Inspection
Smoke control dampers must be inspected before commissioning. After commissioning, the function has to be
tested in regular intervals. Local requirements and
building regulations must be complied with.
The inspection measures to be taken are listed under
Ä
‘Inspection, maintenance and repair measures’
