Dampers are transported by box freight vehicles without direct weather impact, there must not
occur any sharp shocks and ambient temperature must not exceed +40°C. Dampers must be
protected against mechanic damages when transported and manipulated. During transportation,
the damper blade must be in the "CLOSED" position.
Dampers are stored indoor in environment without any aggressive vapours, gases or dust. Indoor
temperature must be in the range from -5°C to +40°C and maximum relative humidity 80%.
Dampers must be protected against mechanic damages when transported and manipulated.
All effective safety standards and directives must be observed during fire damper assembly.
To ensure reliable fire damper function it is necessary to avoid blocking the closing mechanism
and contact surfaces with collected dust, fibre and sticky materials and solvents.
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.
In case that dampers are found unable to serve for their function for any cause, it must be clearly
marked. The operator is obliged to ensure so that the damper is put into condition in which it is
able to function and meanwhile he is obliged to provide the fire protection another appropriate
way.
Before entering the dampers into operation after their assembly and by sequential checks, the
following checks must be carried out.
Results of regular checks, imperfections found and all-important facts connected with the damper
function must be recorded in the "FIRE BOOK" and immediately reported to the operator.
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.
Inspection hole disassembly: release the covering lid by unscrewing screws. Then tilt remove lid
from its original position.
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).
