Mechanism type
Manual
Blade closing mode
Automatic closing with thermal fuse.
The control mechanism has a thermosensitive element that automa-
tically closes the blade when the temperature in the duct exceeds
70°C.
The damper can be closed manually as per the following instructions.
The re damper is equipped with a spring for closing the blade: pay
attention to the hands.
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 as a result of the action of the thermosensi-
tive element, it is possible to manually reopen the damper once the
thermosensitive element has been replaced.
The re damper can be opened manually as per the following in-
structions.
The re damper is equipped with a spring for closing the blade: pay
attention to the hands.
Position indication microswitch
On request, the re damper can be supplied with position microswi-
tch (S1 optional) that signal the closed position of the blade. Refer to
the section Electrical connections for more details.

Valve dimensional information refers to valve type supplied with the
re damper.
A dierent valve model can be used according to installer choice.
The valve shall not be xed directly on the re damper. The valve
shall be xed on the duct and shall not interfere with re damper
functioning. Please see section Installation for further information.
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 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.
The re dampers FBC must be accessible for maintenance and in-
spections.
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
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.
Refer to the section Technical data for blade exposition values.
Minimum distances
In accordance with Articles 7 and 13 of EN 1366-2 respect the mini-
mum distances indicated below.
Minimum distances
1. Vertical lateral wall
2. Floor
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 550 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.
1. Reinforcing beam
Light plasterboard vertical walls
During testing, light plasterboard walls have been used with the fol-
lowing characteristics:
• U-shaped horizontal metal frame (50 mm) and C-shaped vertical
frame (49 mm) made from 0,6 mm thick sheet metal;
• vertical proles placed with a maximum spacing of 1000 mm;
• Filling made of rock wool;
• Each side is made from two plasterboard layers 12,5 mm thick, una-
linged to avoid alignment between the joints of the layer above
and below.
The following indications are given for the installation walls:
• metal proles minimum width: 49 mm;
• metal proles minimum thickness: 0,6 mm;
• vertical proles placed with a maximum spacing of 1000 mm
between each other;
• vertical prole xing with selfthreading screws or by clinching to
the bottom horizontal prole and insertion in the top horizontal
prole;
• proles xed using self-threading screws or by clinching on every
intersection.
• installation of a frame around the damper with base and height
where shown in the installation instructions;
• Filling made of rock wool;
• each side is made from two plasterboard layers 12,5 mm minu-
mum thick, unalinged to avoid alignment between the joints of
the layer above and below.
• the front plasterboards layers are xed using long enough screws
to pass through the lower plasterboard and attach to the steel pro-
le underneath.
