Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages of fire
separating constructions. Damper assembly procedures must be done so as all load transfer from the fire
separating constructions to the damper body is absolutely excluded. Back-to-back air-conditioning piping
must be hung or supported so as all load transfer from the back-to-back piping to the damper is absolutely
excluded.
1. All fire dampers has to be closed during installation process.
2. The control mechanism has to be protected (covered) against damage and pollution during installation
process.
3. Min. gap for installation (installation opening) is 25 mm (circular dimension Ø D + 50 mm or square
dimension AxB + 100 mm).
4. Installation gap must be filled by approved material perfectly in all the installation space volume
(installation gap).
5. The distance between the fire damper and the construction (wall, ceiling) must be minimum 75 mm
according to EN 1366-2. In case that two or more dampers are supposed to be installed in one fire
separating construction, the distance between the adjacent dampers must be at least 200 mm according
to EN 1366-2 paragraph 13.5.
6. Installation openings

10. Damper blade overlaps
9. To provide needed access space to the control device, all other objects must be situated at least 350
mm from the control parts of the damper. Inspection hole must be accessible.
7. The fire damper can be integrated into a solid or gypsum wall construction or into solid ceiling
construction. Damper blade has to be inside of construction (labelled BUILD IN EDGE on the damper
body). The fire damper can also be integrated outside the wall construction. Duct and the damper part
between the wall construction and the damper blade (labelled BUILD IN EDGE on the damper body)
must be protected with fire-fighting insulation.
8. All fire dampers has to be closed during installation process. The damper body should not be deformed
in the course of bricking in. Once the damper is built in, its blade should not grind on the damper body
during opening or closing.

12. Electrical components, wiring diagrams
The blade of fire damper exceeds body
of fire damper by the value “a” and “c” or “e”
and “f”. There has to be enough space in duct
for blade rotation. Values "a" and "c" or "e" and
"f" has to be respected when projecting related
air-conditioning ducts.

13. Before entering the dampers into operation after assembly and after sequential revisions, checks and
functionality tests of all designs including operation of the electrical components must be done. After
entering into operation, these revisions must be done according to requirement set by national
regulations.

Visual inspection of proper damper integration, inside damper area, damper blade, contact surfaces
and silicon sealing.
14. Before entering the dampers into operation after their assembly and by sequential checks, the following
checks must be carried out for all designs.
Inspection hole disassembly: release the covering lid by turning the wing nut and while turning the lid
right or left release it from the security belt. Then tilt the lid and remove it from its original position.
15. Before entering the dampers with manual control into operation after their assembly and by sequential
checks, checks according 14. and following checks must be carried out.
Check of thermal protective fuse and closing mechanism.
Exert pressure on double arm initiation lever with a spring to release the control lever and check its
displacement into the "CLOSED" position. Closing must be smart and the control lever must be firmly
locked with a pawl. In case that the closing is not smart enough and the control lever is not locked with
the pawl in the "CLOSED" position, higher pre-stretch of the closing spring must be set using a ratchet
wheel.
Proper function of the thermal fuse can be checked when the fuse is removed from the starting
mechanism. The initiation lever must be turned over and control lever is moved to position "CLOSED".
If this is not possible, then the starting mechanism spring must be checked or the base plate must be
replaced. The base plate is attached to the damper body with M5 screws.
16. Before entering the dampers with actuating mechanism into operation after their assembly and by
sequential checks, checks according 14. and following checks must be carried out.
Check of blade displacement into the breakdown position "CLOSED" can be done after cutting off the
actuating mechanism supply (e.g. by pressing the RESET button at the thermoelectrical starting
mechanism BAT or cutting off the supply from ELECTRICAL FIRE SIGNALISATION). Check of blade
displacement back into the "OPEN" position can be done after restoration of power supply (e.g. By
releasing the RESET button or restoration of supply from ELECTRICAL FIRE SIGNALISATION).
Displacing the damper blade into "OPEN" position is done the following way:
Release the pawl exerting pressure and return the control lever into the second outlaying position where
the lever is hold by the initiation lever.
17. Manual operation
Without power supply, the damper can be operated manually and fixed in any required position.
Release of the locking mechanism can be achieved manually or automatically by applying the supply
voltage.
18. It is recommended to provide periodical checks, maintenance and service actions on Fire Equipment
by Authorized persons schooled by Producer.
20. All effective safety standards and directives must be observed during fire damper assembly.

1. Damper bodies are supplied in the standard design made of galvanized plate without any other surface
finish.
2. Damper blades are made of fire resistant asbestos free boards made of mineral fibres.
3. Damper controls are made of galvanized materials with no other surface finish.
4. Springs are galvanized.
5. Thermal protective fuses are made of sheet brass, thickness = 0.5 mm.
6. Fasteners is galvanized.
