Valve dimensional information refers to valve type supplied with the
fire damper.
A different valve model can be used according to installer choice.
The valve shall not be fixed directly on the fire damper. The valve
shall be fixed on the duct and shall not interfere with fire damper
functioning. Please see section Installation for further information.
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 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;
• 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
The sizes shown are in mm.
It is recommended to perform a functional test before Installation to
exclude possible damage during transport.
