Warnings
Some damper parts can have sharp edges – therefore it
is necessary to use gloves during damper installation and
manipulation.
In order to prevent an electric injury, re or any other damage
which could result from incorrect damper usage and operation,
it is important to:
1. Install the damper in accordance with the installation manual
and by a properly trained employee.
2. Execute the damper inspection in accordance with this
installation, operation and maintenance manual.
3. Before you can install the smoke damper, it‘s functionality
must be checked according to chapter 3 Check of the
functionality.
This procedure prevents installation of a damper that has
• Distance between dampers and building structures, distribution
technology and ventilation equipment must be large enough
for reliable performance of the installation, functional testing,
inspection and repair.
• The distance between the dampers must be at least 200 mm
according to EN 1366-10.
• The distance between dampers and the wall or ceiling must be
at least 200 mm according to EN 1366-10.
• The gap between the damper and the selfstanding grill (when
installed) must be at least 200 mm according to EN 1366-10.
Otherwise the damper must be tested together with the grill.
• The smoke dampers must be installed with horizontal blade axis.
• Before the installation of the smoke damper, it‘s functionality
must be tested according to the chapter 3 Check of the
functionality.
been damaged during transportation or handling.
Do not install functionless re dampers!
DO NOT INSTALL NONFUNCTIONAL SMOKE DAMPERS!
Operating conditions
Smoke dampers are part of the Smoke and Heat Exhaust
Ventilation System (SHEVS). Functionality of the smoke damper
is following. In case of re damper:
• opens and removes the heat and smoke through a special fan
from the re compartment affected by re or
• closes and prevents the spread of smoke and heat in the re
compartment unaffected by re.
All smoke dampers have electric actuator as standard. They are
designed to be installed in the SHEVS ducts in locations that are
protected from weather.
Systemair smoke dampers are passive in terms of noise. There is
increased noise only when closing or opening the damper in case
of inspection or re (and it takes less than 60 seconds).
1 Installation
The installation must be done as follows:
• Duct connected to the damper must be supported or
suspended so that the damper do not bear its weight.
The damper must not bear any part of the supporting
construction. This could lead to damage and subsequent failure
of the damper.
• Actuator can be on either side of the supporting construction,
but it must be placed so that it is easy to access for inspection
and repairs.
• Changes of smoke damper functionality, caused by transport
or installation, aren´t reclaimable after the installation
(deformations, damages, mechanical damage of the sealing
material, foreign objects which can constrain the blade, wrong
handling of the activating mechanism etc.)
• Before connection of the smoke damper into the ductwork,
smoke damper‘s functionality must be checked again
(according to chapter 3 Check of the functionality).
IT IS NOT POSSIBLE TO CLAIM FAULTY FUNCTIONALITY CAUSED
BY PRODUCTION, TRANSPORTATION OR INSTALLATION AFTER
CONNECTING THE DUCTS TO THE SMOKE DAMPER!
During installation, it is necessary to protect the damper
mechanism and its interior against dirt. The blade must be
in the closed position. It is necessary to avoid deformation
of the damper. Installation and setup of the dampers is always
determined by SHEVS project plans that must comply with the
applicable regulations.
The smoke dampers DKIR1 must be installed according to Fig. 1,
the smoke dampers DKIS1 must be installed according to Fig. 2.
After damper installing into the SHEVS duct it is necessary
to connect electrical installation that must be done only by
authorized persons – connection has to be done according to
Fig. 3 - 7. The actuators have two microswitches indicating
the open and closed positions of the blade - see Fig. 3 - 6.
Setup, install, repair, overhaul and inspections of the dampers
must be done only by the manufacturer or by the personnel
Page 5
202010 | DKIR1 & DKIS1 | 5 / 8
trained by the manufacturer.
Before putting dampers into service after installation
(and in subsequent periodic inspections) visual inspection
and functional test must be conducted. After the visual inspection
and functional test a record must be made into operational diary
(page 6).
2 Operating and Maintenance
2.1 The damper operation
After installation, the damper must be set up into the
operating position - closed. By connecting a power source
to activate the actuator the blade shall move. Respective
switching power supply achieves entry into the operating
position - closed.
2.2 Maintenance
Systemair smoke dampers are maintenance free.
3 Check of the functionality
Switching the supply phase according to Figure 3 - 7 damper
switch to the „open“:
• The blade must come to the fully open position and must
remain there detented.
• After reaching the end position of the blade the appropriate
signaling circuit must switch on.
Switching the supply phase according to Figure 3 - 7 switch
damper to the „closed“:
• The blade must come up to the fully closed position
and remain there detented.
• After reaching the end position of the blade the appropriate
signaling circuit must switch on.
Now the damper is in standby mode, so it must rest for normal
operation.
4 Inspection of the damper
Each damper should be inspected after installation and every
12 months using following steps:
1. Identication of damper
2. Date of inspection
3. Check of the electrical connection of the activation
mechanism
4. Check of the the electrical connection of the end switches
5. Check of the damper for cleanliness and eventually treatment
(where necessary)
6. Removing of the cover of the inspection lid.
7. Check of the inspection lid, cover tightness and eventually
correction and record (where applicable)
8. Check of the blade and sealings, and eventually correction
and record (where applicable)
9. Check of the safety damper closure - details see Chap. 3
10. Check of the damper functionality (details see Chap. 3)
opening and closing by the control system, tracking
the physical behavior of the dampers and signalization
of the end positions, and eventually correction and record
(where applicable)
11. Closing of the cover of the inspection lid.
12. Set up into the operating position - see Chap. 2.1
13. Record into operational diary (page 6) with name
and signature of the checker.
The damper is part of the SHEVS. Therefore the system must
be checked as specied in its operational and maintenance
requirements.
