Smoke exhaust dampers -single are classified as according to EN
13501-4.
Smoke exhaust dampers - single are shutters in smoke exhaust piping systems. Dampers are designed to
remove heat and combustion products (e.g. smoke) from single fire compartment. The damper blade is
operated by an actuating mechanism. The dampers can be installed in various duct sizes with respect to the
field of direct applications according with EN 1366-9.
The field of direct applications based on tests results is acceptable according to EN 1363-1, part A.1 and
A.2, EN 1366-2, part 13 and EN 1366-10, part 9.
In the event of fire the Smoke and Fire ventilation system opens the damper in the affected section which
removes combustion products and heat from this section.
4. To provide needed access space to the control device, all other objects must be situated at least 350 mm
from control parts of the damper. Inspection hole must be accessible.
1. During installation the damper blade must be in position “CLOSED”. The damper body should not be
deformed in the course of bricking in. Once the damper built in, its blade should not grind on the damp-
er body during opening or closing.
2. During installation the control mechanism must be protected against damaged and pollution.
3. Damper assembly procedures must be done so as all load transfer from the fire separating constructions
to the damper body is absolutely excluded.
Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3 zm.A2.
5. Statement of installations
Smoke extraction dampers - single are designed for installation with horizontal blade axis.
Air flow (smoke) must be directed from the control device side (see arrow on the damper body).

7. Flanges
6. The blade overlaps
Flanges for square fire dampers are 30 mm wide
with oval hole.
The blade of dampers exceeds body of fire damper by the
values “a” and “c”. There has to be enough space in duct
or installation shaft for blade rotation. Values have to be
respected when projecting related air - conditioning duct.

4. 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 regula-
tions.
1. Assembly, maintenance and damper check can be done only by qualified persons, i.e. “AUTHORIZED
PERSONS” that have been trained by the manufacturer.
2. All effective safety standards and directives must be observed during fire damper assembly.
3. Manual operation:
Any position of the damper blade can be manually set by using a special key. The functionality of the
damper can be then easily tested.
5. After fire damper assembly the following checks must be carried out:
Visual inspection of proper fire damper integration, inside fire damper area, fire damper blade, contact
surfaces and silicon sealing.
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.
The adjustment of the blade can be proven by connecting the power supply to the actuator (or by the
signal from the Smoke and Fire Ventilation system). The blade is adjusted to the position "OPENED"
and then back to position "CLOSED".
