Blade closing mode
Automatic closing with thermal fuse.
The control mechanism has a thermosensitive element that auto-
matically closes the blade when the temperature in the duct exceeds
70°C.
The damper can be closed manually as per the following instructions.
The fire 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 fire damper can be opened manually as per the following in-
structions.
The fire damper is equipped with a spring for closing the blade: pay
attention to the hands.
Position indication microswitch
On request, the fire damper can be supplied with position mi-
croswitch (separate accessorial) that signal the closed position of the
blade. Refer to the section Electrical connections for more details.

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
We reserve the right to make changes without prior notice
