Fire Dampers
PK-I-R-EI60S, -EI90S and -EI120S
Systemair Fire dampers are manufactured to comply with latest
European Standards. With wide product range and sizes for 60, 90
and 120 minute resistance for round and rectangular ducting.
All dampers as standard are designed and certified for EI-S
performance conformity.
PK-I fire damper units are designed to be imbedded into the fire
partition walls. Installation of these units are clearly indicated on
pages 7-9.
All units as standard are available with manual rearmament lever
and Actuator driven with optional accessories such as micro-
switches, Electromagnets and communication controller units.
Fire Dampers with manual rearmament lever
Fire Damper is set to closed position when thermal-fuse link is
ruptured or a signal is given to the Electromagnet to release the
damper blade from open to closed position.
After closure, the damper blade is secured in closed position
mechanically and can only be opened manually.
Fusible link manufactured and secured in position with a Bi-metal
solution which is designed to release the link mechanism when the
air temperatures in the duct system reach 72 °C with tolerance
±1,5 °C for the period of 30 to 60 seconds.
Electromagnet maintains the damper blade in open position by
maintaining the current through its mechanism. Upon shut-off
electrical current, the Electromagnet automatically releases the
damper blade mechanism and then the closed or safe position is
reached. The damper blade can only be placed in operation by
manually releasing the mechanism from the closed position and
enabling the current through the electromagnet to hold the damper
blade mechanism in open position.
Actuator driven fire dampers
Fire damper can be equipped with actuator that closes the damper
blade on demand of Building Management System or signal
received from electro-thermal fuse. As standard all actuator fitted
fire dampers are equipped with electro-thermal fuse, which when
reaching or exceeds ambient temperature of 72 °C with tolerance
±1,5 °C, releases actuator and closes the damper blade to safe
position within 60 seconds.

Installation of Round Fire Dampers
Fire Dampers
Fig. 5 Spacing between the dampers
Fig. 6 Correct position of closed damper blade
Fire damper placement and clearances
Damper release mechanism or actuator can be located on
any side of the wall or ceiling.
However it must be positioned in such way that there is
easy access provided for inspection or service.
Examples of damper locating can be seen in fig. 7.
Spacing between the fire dampers must be a minimum of
200 mm. At mechanical manufacture must be on the side
where mechanism is situated free space the side where of
min. 500 mm left.
Fire damper is embedded into fire partition construction in
such way that when the damper blade is in closed position,
the blade will be situated within the wall (fig. 8).
Damper can be embedded in the wall or in the ceiling
with min. thickness of 110 ± 10 mm according to STN EN
1366-2.
All connecting ducts to the fire damper must be supported
or suspended in such way that the duct weight would not
lean on damper or damper flanges. Further more the
damper should not bare any weight from the above or
surrounding construction of the wall , this can result in
distortion of the casing and ultimately malfunction of the fire
damper.
All dampers are designed to be installed with damper blade
in parallel 0º to horizontal position or 0º in vertical position.
Any other angle will compromise the integrity and function
of the fire damper.
Note: After installation, Fire damper functionality must be
tested (see operating manual).
A
vailable Duct connections
Round fire dampers are provided as standard without any
rubber gaskets or flanges.
Accessories such as air tight joint connection (Code NT, Fig
3a), and-or pre-drilled flanges (Code P, Fig 3b) can be
provided separately on demand
Accessories are supplied non mounted and separately to be
mounted on site by others.
Note: During the installation of the Flanges, proper sealant
and gasket must be used to avoid any leakages at the duct
connection.

An intumescent gypsum mixture can be used to
seal the opening section between the wall and the
fire damper.
The entire wall cross-section must be perfectly
filled with gypsum mixture
The opening provided for this installation should
be no less than Ød + 160 mm.
Fire damper is embedded into fire partition
construction in such way that when the damper
blade is in closed position, the blade will be
situated within the wall (fig.7).
Damper can be embedded in the wall or in the
ceiling with min. thickness of 110 ± 10 mm
according to STN EN 1366-2.
All connecting ducts to the fire damper must be
supported or suspended in such way that the duct
weight would not lean on damper or damper
flanges. Further more the damper should not bare
any weight from the above or surrounding
construction of the wall , this can result in
distortion of the casing and ultimately malfunction
of the fire damper.
Limit of damper embedding into the wall, or the
ceiling is stated by marking made on the fire
damper casing from the mechanism or actuator
side(see detail X - fig. 8 and fig.8a).
For all fire dampers which are equal or larger than
size ≥Ø 400 mm, the fire damper casing has an
built-in reinforcement at the limit of fire damper
embedment for extra support (see fig. 8b).
Fire damper is embedded into fire partition Floor
or Ceiling in such way that when the damper
blade is in closed position, the blade will be
situated within the wall (fig.9).
Damper can be embedded in the wall or in the
ceiling with min. thickness of 110 ± 10 mm
according to STN EN 1366-2.
All connecting ducts to the fire damper must be
supported or suspended in such way that the duct
weight would not lean on damper or damper
flanges. Further more the damper should not bare
any weight from the above or surrounding
construction of the wall , this can result in
distortion of the casing and ultimately malfunction
of the fire damper.

Installation of Round fire dampers
Installation of PK-I-R into the wall using Rockwool
To seal between the wall and the fire damper Rockwool
with a min. density of 80-100 kg/m3 can be used. Once
the fire damper is properly secured into the wall, cover
plates made of calcium-silicate can be used to close or
finish the wall openings (fig. 12).
Cover plates are not a part of fire damper and are
delivered as damper accessories, which must be
indicated and specified at the order.
Cover plates are fire resistant mastic Intumex MA.
From one side of the wall cover plates are mounted
together with the damper to the wall opening.
The entire opening between the fire damper and the
wall in the full depth of the wall around the fire damper
must be filled perfectly with Rockwool of Density 80-
100 kg/m3.
Once the above two procedures are fulfilled, then after
the opening from the other side of the wall can be
closed with cover plates to secure and finish the
installation.
A minimum opening diameter of Ød + 60 mm is
required for each size of fire damper for it to be
properly imbedded into wall cross section. Outer
diameter of cover plates for closure are normally Ød +
X as standard (see fig. 12a).
Metal anchors are used to fasten the cover plates to
the wall or ceiling made of concrete, bricks or building
blocks. All anchors should have a minimum length of
70 mm and to accommodate a screw diameter no less
than 5 mm.
After the installation is completed, the damper’s
operation must be tested (see operating manual).

To seal between the wall and the fire damper Rockwool
with a min. density of 80-100 kg/m3 can be used. Once
the fire damper is properly secured into the wall, cover
plates made of calcium-silicate can be used to close or
finish the wall openings (fig. 12).
Cover plates are not a part of fire damper and are
delivered as damper accessories, which must be
indicated and specified at the order.
Cover plates are fire resistant mastic Intumex MA.
From one side of the wall cover plates are mounted
together with the damper to the wall opening.
The entire opening between the fire damper and the
wall in the full depth of the wall around the fire damper
must be filled perfectly with Rockwool of Density 80-
100 kg/m3.
Once the above two procedures are fulfilled, then after
the opening from the other side of the wall can be
closed with cover plates to secure and finish the
installation.
A minimum opening diameter of Ød + 60 mm is
required for each size of fire damper for it to be
properly imbedded into wall cross section. Outer
diameter of cover plates for closure are normally Ød +
X as standard (see fig. 12a).
Metal anchors are used to fasten the cover plates to
the wall or ceiling made of concrete, bricks or building
blocks. All anchors should have a minimum length of
70 mm and to accommodate a screw diameter no less
than 5 mm.
After the installation is completed, the damper’s
operation must be tested (see operating manual).
X= 200 mm for dimensions PK-I-R/ Ø100 to Ø 560 mm
X= 300 mm for dimensions PK-I-R/ Ø630 to Ø 1000
mm
Outer diameter of scabs is stated by the ratio Ød + X (see fig.
12a).
For suspending the scabs to the wall or ceiling are used
metal anchors for given building construction (concrete,
bricks, porous concrete, etc.) with the depth of screw in min.
70 mm and with screw diameter for min. 5 mm.

Operations & Maintenance of fire dampers
Putting the damper into operation
Dampers in standard manufacture- ZV and with additional equipment- DV1÷DV6
Mechanical triggering
By pulling the securing pivot (2) we lock-off the adjusting lever of the mechanism (1) and we move it from the
CLOSED position to OPEN position. When turning the adjusting lever (1) it is simultaneously tensing also the
return- spring (10) that is why it is needed to use only light power to tense the spring. Securing pivot (2) must
easily fit into securing mechanism (3) of actuating lever (4).

Operations & Maintenance of fire dampers
Damper el. function check
If the damper is in manufacture DV3÷DV6 with electromagnet it is necessary to test the mechanism function
also with electromagnet. Electromagnet receives the signal for actuating (for example from the central building
system) releases the actuating lever (4) and mechanism closes. Adjusting lever (1) immediately moves from
position OPEN to position CLOSED. If the damper is in manufacture with terminal switch (9) it must signal
closing the leaf after actuating the mechanism
Dampers with actuator in manufactures DV7, DV9-T and DV9-T-ST
Putting damper into operation
After connecting the actuator to el. power (see wiring schemes according to damper manufacture) the
electromotor is activated and puts the damper into operation position. That means that the damper leaf opens.
Control system, which the damper is connected to signals (according to damper connection) open or closed
position of damper leaf.
Damper function check
Damper function is checked when we press and hold the switch on thermo electrical release device (heat fuse)
as shown in fig. 37. With the switch we simulate failure of heat fuse. It is necessary to hold the switch in ON
mode during the whole damper function check. Actuator puts the damper into accident position- it closes the
damper leaf with the energy of return spring of the actuator. Damper should close within app. 20-30 seconds
(depends on operation temperature). Position of the leaf is possible to check visually through inspection lid or
the leaf position is signaled by control system which the damper is connected to.
Damper must close also at any electricity supply drop out when the damper leaf is closed with energy of
actuator’s return spring.

Visual check
After putting the damper into operation mode it is necessary for all the damper types to demount the inspection
lid and check the damper leaf position and also check possible visible damper leaf and other damper parts
damages visually. Visual check is needed for both leaf positions - OPEN / CLOSED.
Operation, check and maintenance
Operation conditions
Operator keeps fire dampers in operation and in safe status during their whole period of service according to
operation manual published by the producer. It is not allowed to do any changes or modifications on the
dampers and any damper parts cannot be removed without producer’s permission. Operator provides
regular checking of the dampers according to valid instructions and norms given by the country. If not stated
in other way, operator does the damper check once per 12 months. Damper checking is provided by skilled
person. Fire damper status determined during the check is noted into operation diary with the date of the
check, name and last name in bold and signature of the person that has done the check. If any inadequacies
were determined it is needed to note also proposal for their elimination into the operation diary.

Operations & Maintenance of fire dampers
Visual check
During visual check are possible visible damages on the damper parts checked. From outer side of the damper
is damper surface, panel with release mechanism (for manufactures ZV and DV1-DV6) or actuator (for
manufactures DV7, DV9-T and DV9-T-ST) checked. During visual check from the inner part of the damper is
damper inspection lid demounted and there the sealing is checked. Damper inner casing, damper leaf, heat
fuse and all the sealing’s inside the damper are checked as well. Damper leaf must be open in operation
mode.
Fire damper mechanical function check
During the check the damper should be in operation mode. That means that during visual check is the damper
leaf open. Correct function of damper mechanical release is checked by pulling the release lever (4) what
releases safety mechanism (3) and adjusting lever (1) moves from position OPEN to position CLOSED.
Closing the damper is provided by spring (10). Securing pivot (2) fits into holder (5) and by that is the damper
leaf secured against opening. After actuating the damper immediately closes. Process of closing must be
fluent without the adjusting lever (1) stopping in any other position as CLOSED. If the damper is in
manufacture with terminal switch (9), by actuating the mechanism must the terminal switch (9) signal leaf
closing. By mechanical function damper check, please push the actuating lever (4) with finger and pull your
hand back from the damper, so that it will not get injured by the adjusting lever!
After mechanical function check we put damper into operation mode. By pulling the securing pivot (2) we
release adjusting lever of mechanism (1) and move it from the position CLOSED to position OPEN. While
turning the adjusting lever (1) return spring (10) is tensed at the same time that is why we need to pull with light
power. Securing pivot (2) must fit easily into safety mechanism (3) of release lever (4).

Replacement of Fusible Link:
Heat fuse is located inside the damper casing. From the design point of view it is a part of the panel with
release device. Heat fuse consists of two parts connected with solder made of low- fusible alloy of non-steel
metals. In case of any reason it is necessary to exchange the heat fuse it is possible to do it through inspection
lid. When exchanging the heat fuse we push the pivot from the top with a cross-head screwdriver according to
fig. 39 and we replace the damaged heat fuse through inspection lid. After mounting the next fuse we release
the pivot. Then the exchange of the heat fuse is finished. Damaged heat fuse is possible to exchange only with
new original fuse supplied by damper producer.

Electrical function check
Accessory types: DV3 – DV6
Electromagnet receives a signal to trigger (for example, from the central system of the building), releases the
release lever (4) and the mechanism closes. Adjusting lever (1) immediately moves from position OPEN to
position CLOSED. If the damper is in manufacture with terminal switch (9) it must signal closing of the leaf
when the mechanism triggers.
Accessory types: DV7, DV9-T / T-ST
Damper function is checked by pushing and holding the switch situated on thermo electrical release device
(heat fuse) as shown in fig. 37. Doing this simulate failure of heat fuse. It is necessary to hold the switch in ON
mode during the whole damper function check. Actuator puts the damper into accident position- closes the
damper leaf with energy of actuator’s return spring. Fire damper should close within app. 20 to 30 seconds
(depends on operation temperature). Damper leaf position is possible to check also visually through damper
inspection lid or position of the damper leaf signals control system which the damper is connected to. Damper
must close at any power drop-out while the damper leaf is closed with energy of actuator’s return spring.
