MAInTEnAnCE AnD InSPEC TIonS
Fire dampers and control mechanisms do not require rou-
tine maintenance.
Extraordinary maintenance (repairs) and periodic inspec-
tion operations are the responsibility of the ventilation sys-
tem operator.
The implementation of a periodic inspection plan allows to
guarantee the efficiency and functionality of the fire damp-
ers for the fire safety of the building.
Periodic inspection and cleaning
Periodic inspection shall be performed in accordance with
the requirements of the law or by the building regulations
or other local regulations.
In the absence of prescriptions (or their complement), in
accordance with point 8.3 of the En 15650 standard, it is
recommended to carry out an opening and closing test
at intervals of no more than 6 months and checking the
correct movement of the blade and correct operation of
the 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 sup-
port.
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.
It’s not allowed to use abrasive detergents or mechanical
abrasive cleaning systems.
These indications comply with the standards En 15650 an-
nex D and En 15423 annex C.
Repair
For safety reasons, repair activities involving fire-fighting
components must be carried out only by qualified person-
nel.
only original spare parts supplied by the fire damper man-
ufacturer 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 po-
sition.
Keep records of all inspections, repair activities, any prob-
lems encountered 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 ac-
cordance with national legislation. For electrical and elec-
tronic parts also refer to EU Directive 2011/65.
