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 rotat-
ing the lever counterclockwise once the element has been replaced.
Position indication microswitches
On request, the re damper can be supplied with position mi-

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.
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 6 months:
• If the damper is connected to a remote control or command sys-
tem (eg BMS or alarm or re detection), that responds correctly to
commands by performing at least one opening and closing test
and verifying the correct movement of the blade and the correct
functioning of the microswitches (limit switches).
• If the damper is not connected to a remote control or command
system, manually execute an opening and closing test and check
the correct movement of the blade and the correct functioning of
the microswitches (limit switches) if present.
Together with the control activities, it is recommended to visually
verify the absence of corrosion, the integrity of the electrical wiring
and the sealing of the construction support.
Damper cleaning is included in the ordinary maintenance activities
of the ventilation ducts.
Fire dampers can be cleaned with a dry or wet cloth.
In the case of resistant dirt, it is possible to use normal household
detergents.
If prescribed for the type of building, it is possible to use disinfectant
detergents.
The use of detergents or mechanical abrasive cleaning systems is not
permitted.
These indications comply with the standards EN 15650 annex D and
EN 15423 annex C.
Repair
For safety reasons, repair activities involving re-ghting compo-
nents 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.

8/16
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 immedi-
ately after installation to exclude accidental damage to the product
and interference with mounting components.
Positioning brackets before xing
1. Positioning brackets
Blade rotation axis positioning
The re damper can be installed with the blade axis positioned verti-
cally or horizontally or tilted at any angle.
Installation of exible connectors in order to balance out the
ventilation ducts expansion
CAUTION: Refer anyway to law and national standardization.
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 com-
plete 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 interfer with opening
/ closing movement of the blade.
Transfer Application (application not connected to air ducts on
one or both sides)
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.
• End cap with mesh shall be mounted on the side not connected
to air duct.
• End cap with mesh is made from galvanized steel sheet.
• End cap with mesh is supplied loose from the re damper.

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
walls/oor of the same type but with greater thickness and/or densi-
ty 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, con-
crete panels, perforated cell elements in concrete or brick in accord-
ance with the following characteristics:
• minimum thickness 100 mm;
