comands the closing of the damper.
Blade opening mode
Make sure that the damper is open before the ventilation system
start-up, otherwise there is a risk of product malfunction.
In case of closed damper by pressing the closing button or remotely
by electromagnet (magnetic version), it is possible to manually open
the re damper blade by rotating the lever antyclockwise.
For power supply interruption electromagnet, provide power supply
and pull the magnet knob before opening the re damper.
In case of closed damper as a result of the action of the thermosen-
sitive element, it is possible to manually reopen the damper by rota-
ting the lever counterclockwise once the element has been replaced.

MAINTENANCE AND INSPECTIONS
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 re damper.
The implementation of a periodic inspection plan allows to guaran-
tee the eciency and functionality of the re dampers for the re
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 specic 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;
• Check the correct opening and closing of the re damper by ma-
nual operation according to the instructions in the technical ma-
nual of the re damper;
• Check the opening and closing operation of the damper control-
led by the re alarm system (if present);
• Check the operation of the end switches in open and closed state,
adjust and report if necessary;
• Conrm that the damper fulls 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 re-ghting componen-
ts must be carried out only by qualied personnel.
Only original spare parts supplied by the re 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 re 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
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 re damper can be installed with the blade axis positioned verti-
cally or horizontally or tilted at any angle.
Positioning brackets before xing
1. Positioning brackets
Installation of exible 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 re
dampers are installed require the use of exible connectors.
Flexible connectors compensate any duct thermal expansion and
wall bending in case of re.
Flexible connectors are used to limit re damper stresses due to ex-
ternal forces in case of re and to preserve re resistance class.
In general it is always appropriate the use of exible connectors for
the followings installations:
– light walls;
– Plasterboard and rock wool or Fire Batt (Weichschott) sealing;
– Applique xing system.
Flexible connector must be normal ammability and in case of re
the grounding bonding should disconnet to guarantee the comple-
te separation between re damper and connected air duct.
When exible connectors made of conductive material (e.g. alumi-
num) are used, no additional grounding bonding is required.
Despite exible connector installation, the re damper must be in-
stalled in the construction support so that its weight does not aect
damper’s installation position both during normal operation and in
case of re.
It is recommended not to compress exible 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 exible 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 specic obligation is required.
Following tests performed as per EN 1366-2, section 6.3.6 Standard,
it is possible to install the re damper free from air duct from one or
both sides.
• Attention: re resistance classication for transfer application is
conform to section Fire resistance classication according to EN
13501-3-2009 limited to EI 90S if the ducted classication is higher.

Construction supports characteristics
The European standard for re dampers foresees a precise correlation
between the wall/oor characteristics and the re resistance class
obtained, as well as the correlation between wall/oor used for the
test and wall/oor used for the actual installation.
The test results obtained on a type of wall/oor are valid also for wal-
ls/oor of the same type but with greater thickness and/or density
than those used in the test.
For plasterboard walls, the test results are also valid for walls with a
greater number of plasterboard layers on each side.
As a result, the indicated thickness and density characteristics are to
be considered as minimum values.
The wall/oor in which the re dampers are installed must be re
class certied according to the standards foreseen for the structure.
Rigid walls
Can be made with aerated concrete blocks, poured concrete, concre-
te panels, perforated cell elements in concrete or brick in accordance
with the following characteristics:
• minimum thickness 100 mm;
• minimum density 500 kg/m³.
The use of a reinforcing beam above the opening is recommended
for walls made from concrete blocks, bricks or in concrete cell ele-
ments.
For walls built with perforated elements, it is also recommended that
the area of the opening be made from full elements (for example
aerated concrete blocks) to guarantee the correct adhesion of the
mortar.

Gypsum blocks light walls
Gypsum blocks wall can be built with special solid gypsum blocks
with interlocking shaped edges as indicated in the supplier's in-
structions and according to the following characteristics:
• minimum thickness 70 or 100 mm according to the type and resi-
stance class required;
• minimum density 995 kg/m³.

Aerated concrete oors can be built during installation or with pre-
formed slabs with interlocking shaped edges according to the fol-
lowing characteristics:
• minimum thickness 100 or 150 mm according to the type and re-
sistance class required;
• minimum density 650 kg/m³
Poured concrete oors
Poured concrete oors can be built during installation or with pre-
formed slabs with interlocking shaped edges according to the fol-
lowing characteristics:
• minimum thickness 100 or 150 mm according to the resistance
class required;
• minimum density 2200 kg/m³.
