MAINTENANCE AND INSPEC TIONS
Fire dampers and control mechanisms do not require routine main-
tenance.
Extraordinary maintenance (repairs) and periodic inspection opera-
tions are the responsibility of the ventilation system operator.
It is recommended to keep enough space (about 200mm) for using
or replacing the control mechanism or for maintenance. Also provide
the necessary space to remove the ventilation duct from the damper
whenever necessary.
It is recommended to provide inspection hatches on both sides of
the ducts connected to the fire damper.
The implementation of a periodic inspection plan allows to guaran-
tee the efficiency and functionality of the fire dampers for the fire
safety of the building.
Periodic inspection and cleaning
„
Periodic inspection shall be performed in accordance with the re-
quirements of the law or by the building regulations or other local
regulations.
In the absence of specific regulations (or to their complement), in ac-
cordance with point 8.3 of the EN 1560 standard, it is recommended
to carry out the following control activities at intervals of no more
than 12 months:
• Check the servomotor electrical wiring for damage (where appli-
cable);
• Check end-switch wiring for damage (where applicable);
• Check damper cleanliness and clean where necessary;
• Check the condition of blades and seals, rectify and report where
necessary;
INSTALLATION
The sizes shown are in mm.
It is recommended to perform a functional test before Installation to
exclude possible damage during transport and another test imme-
diately after installation to exclude accidental damage to the product
and interference with mounting components.
Blade rotation axis positioning
„
The fire damper can be installed with the blade axis positioned verti-
cally or horizontally or tilted at any angle.
Positioning brackets before fixing

1.
Positioning brackets
• Check the correct opening and closing of the fire damper by ma-
nual operation according to the instructions in the technical ma-
nual of the fire damper;
• Check the opening and closing operation of the damper control-
led by the fire alarm system (if present);
• Check the operation of the end switches in open and closed state,
adjust and report if necessary;
• Confirm that the damper fulfils its function as part of the control
system (where necessary);
• Check that the damper is left in its normal operating position, whi-
ch usually corresponds to the open position.
Repair
„
For safety reasons, repair activities involving fire-fighting componen-
ts must be carried out only by qualified personnel.
Only original spare parts supplied by the fire damper manufacturer
must be used.
A functional test must be performed after each repair.
.
At the end of the inspection, cleaning or repair operations, check that
the fire damper is in the normal operating position.
Keep records of all inspections, repair activities, any problems en-
countered and their resolution.
This practice, even when not mandatory, is very useful in practice.
Disposal
„
Disposal in case of destruction must be carried out in accordance
with national legislation. For electrical and electronic parts also refer
to EU Directive 2011/65.
Installation of flexible connectors in order to balance out the
„
ventilation ducts expansion
ATTENTION: the following indications must be considered
binding only if legislation or local regulation where the fire
dampers are installed require the use of flexible connectors.
Flexible connectors compensate any duct thermal expansion and
wall bending in case of fire.
Flexible connectors are used to limit fire damper stresses due to ex-
ternal forces in case of fire and to preserve fire resistance class.
In general it is always appropriate the use of flexible connectors for
the followings installations:
– light walls;
– Plasterboard and rock wool or Fire Batt (Weichschott) sealing;
– Applique fixing system.
Flexible connector must be normal flammability and in case of fire
the grounding bonding should disconnet to guarantee the comple-
te separation between fire damper and connected air duct.
When flexible connectors made of conductive material (e.g. alumi-
num) are used, no additional grounding bonding is required.
Despite flexible connector installation, the fire damper must be in-
stalled in the construction support so that its weight does not affect
damper's installation position both during normal operation and in
case of fire.
It is recommended not to compress flexible connectors in the in-
stallation phase.
Flexible connector must be at least 100mm long and in order that
possible duct thermal expansions are balanced.
Take care that the flexible connector does not interfere with opening
/ closing movement of the blade.
Transfer Application (application not connected to air ducts on
„
one or both sides)
Note: For this application please refer to national legislation to verify
if any specific obligation is required.
Following tests performed as per EN 1366-2, section 6.3.6 Standard,
it is possible to install the fire damper free from air duct from one or
both sides.
• Attention: fire resistance classification for transfer application is
conform to section Fire resistance classification according to EN
13501-3-2009 limited to EI 90S if the ducted classification is higher.
We reserve the right to make changes without prior notice
