OPERATION
Technical data and operation: see separate brochure.
According to CE marking, the fire damper must close by
means of a temperature-based tripping mechanism. The
fire dampers are available either with a mechanical thermal
fuse or an actuator motor. The motorized model may also be
included a smoke-detection-based tripping mechanism. In
such case, the fire damper should be connected to a control
and monitoring system FICO delivered by Fläkt Woods. The
system can also be used for the automatic function testing
of fire dampers, without causing interruptions to system op-
eration.
FUNCTION TESTING
Damper with thermal fuse::
Press the red testing lever, until the spring closes the damper
blade. Watch out for the turning spring tensioning handle! Turn
the blade back into the open position, until you hear the retaining
clip snap. The function testing interval is determined separately
for each building, however the test is to be performed at intervals
not exceeding six months (EN 15650, 8.3)
Motorized damper:
The function testing for the motorized model can be performed
by cutting off the power supply by using the rocker switch of
the thermal trip (BAE72B-S) connected to the motor. The spring
should then close the blade. The function testing can also be
done by means of the control and monitoring system FICO, either
manually or automatically. The recommended function testing in-
terval for the motorized model is 48 hours.
MAINTENANCE
Perform the following measures in conjunction with periodical
maintenance or possible repair work:
Check that the fire damper casing is not damaged and that the
blade can move freely.
Check that the actuator is properly fastened onto damper cas-
ing and blade shaft.
Check that the damper blade and sealings are undamaged.
Check that the damper blade is completely open during normal
operation.
Check that the damper blade is able to close and open freely.
WARNING! Never put your hands inside the damper while it is
closing.
CLEANING
Clean the fire damper by means of a vacuum cleaner. Avoid
chemical cleaning agents.
SPARE PARTS
Actuator: see type specification on the actuator.

INSTALLATION OF FIRE DAMPER INTO BUILDING ELEMENTS (WALLS OR INTERMEDIATE FLOORS)
MADE OF ROCK MATERIAL AND HAVING FIRE CLASS EI 30 / EI 60 / EI 90 / EI 120,
DAMPER LENGTH 500 OR 400 MM
1. The dimensions of the building element penetration must be
at least: bxh = (B+80mm) x (H+80mm), see FIGURE 2.
2. Insert the fire damper inside the building element penetration
so, that the damper blade is located in the middle of the ele-
ment.
3. The damper shaft may be placed either horizontally or verti-
cally.
4. Cast in the gap “s” (FIGURE 2) throughout the thickness of the
building element. Use incombustible, rock-based, fine-grained
gypsum or concrete. Protect the damper for the time of cast-
ing.
5. Check the functioning of the fire damper and proper mov-
ing of its blade. Clean the damper, if necessary. Place plastic
covers on the openings and keep them covered, until ducts
are connected to the damper.
6. Tensioning the spring of damper with thermal fuse: Turn the
blade into the open position, until you hear the retaining clip
snap. After this, you can check the closing function of the
damper by pressing the red testing lever.
7. The function testing of the motorized model can be performed
de-energized by means of the hexagon wrench delivered
with the product, and energized by using the switch of the
thermal trip. Note! If you open the damper with the hexagon
wrench, be sure to release the damper back to the closed
position before switching on the current.
8. Connect ducts to the damper according to the instructions
provided by the designer or manufacturer. Each damper is
equipped with a flange joint.
9. The fastening of the fire damper must have a fire resisting
capacity that is at least as high as the fire classification of
the penetrated building element (the fire resistance rating of a
class EI 60 element is R 60, etc.).
10. If the fire damper is used as an air transfer or air terminal de-
vice, it must be equipped with a protective grille. The distance
between the grille and the damper blade in the open position
must be at least 30 mm. In case of large fire dampers, an
extension piece must be installed between the grille and the
damper blade.

1. Firstly, mount the installation frame ER2 into the fire-separat-
ing building element. Make sure that the wider flange of the
frame is on the side of the fire damper. Make sure that the
frame is mounted into the correct position, so that the actua-
tors of the fire damper end up on the intended side of the
building element.
2. The dimensions of the building element penetration must be
at least: bxh =(B+80mm) x (H+80mm).
3. Insert the frame ER2 into the penetration.
4. Cast in the gap throughout the thickness of the building ele-
ment. Use incombustible, rock-based, fine-grained gypsum or
concrete. Protect the damper for the time of casting.
5. Place the fire damper inside the frame and fasten it by using
the fixing plates and bolts delivered with the damper.
6. Check the functioning of the fire damper and proper mov-
ing of its blade. Clean the damper, if necessary. Place plastic
covers on the openings and keep them covered, until ducts
are connected to the damper.
