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.

FK120/FK90 Fire damper Instructions for installation, operation and maintenance

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.

7. 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
