Installation
Fire dampers ETCE and ETCS (with stainless steel casing)
must be installed according to this installation manual, see
pages 4-9.
General instructions for using hangers
The fire damper must be supported so that the ductwork
connected to the damper does not impose any load on the
damper body.
In practice, a good way to fit the product centrally in the
installation opening is to hang the ductwork prior to sealing.
If the subsequent sealing is done using grouting concrete,
also other types of support can be used during installation
until the concrete has dried.
It is essential that no stress is imposed on the fire damper
or the duct. The hanging and fixing solution must be ade-
quate in the event of fire. The hanger must be located either
at the fire damper or immediately after the duct connection.
Designing the use of hangers is the responsibility of a
structural engineer.
Operation and function testing
According to CE marking, a fire damper must always be
equipped with a tripping mechanism based on
temperature. Fire dampers can be delivered equipped with
either a fuse mechanism or an actuator.
ETCE motorized fire dampers may additionally be linked to
a smoke detection based tripping mechanism. A tripping
system based on smoke detection is easy to install using
FläktGroup’s FICO control and monitoring system. The FICO
system can also be used for automatic function tests of fire
dampers.
The function testing for the motorized damper can be per-
formed by cutting off the power supply by using the switch
of the thermal trip connected to the motor. The spring
should then close the damper. The function testing can also
be done by means of the control and monitoring system
FICO, either manually or automatically. The recommended
automatic function testing interval for the motorized model
is 48 hours.
The operation of the fuse mechanism is tested by
pushing the red test button – the spring should close the
blade. Beware of the reset handle as it will rotate rapidly
during test operation. To reset the mechanism, turn the
handle until the mechanism clicks.
The function testing interval is always determined
separately for each building, but testing must be carried
out at least twice a year according to product standard EN
15650:2010.
Maintenance
According to product standard EN 15650:2010, fire damp-
er installations and function are to be checked every six
months (see example of check list beside).
WARNING! Never put your hands inside the damper while
it is closing.
Clean the fire damper by means of a vacuum cleaner. Avoid
chemical cleaning agents.

Installation of ETCE fire damper outside building elements with fire classification
EI 60 (Fig. 9-11)
1. Install the duct in the usual manner so that it pene-
trates the building element, and seal the openings (M or
S) using an approved method.
2. Prepare the fire damper for remote of wall installation:
Place the supplied accessory clamp collar ETCZ-1-
aaa-1 (3) as shown in Figure 11 over the taping on the
fire damper and tighten it in place with the screws on
the clamp collar. NOTE. The custom-built clamp collar is
a mandatory accessory for installation outside building
elements.
3. Connect damper to duct according to the instructions
provided by the designer or manufacturer and remove
the blade supports. Use rivets of sufficient length (e.g.
DIN 7337 4x10 or shorter) to lock fire damper to the
duct. Note! Always check that damper blade can rotate
freely and rivets/screws are out of the way. Access
panel should be installed next to the damper to enable
necessary cleaning and inspection.
4. Support the duct installation so that there is no extra
load on the fire damper. In horizontal installation (Fig-
ures 9-10) the dimensioning of threaded rod hangers
(1) can be done based on the following table. In vertical
installation (Figure 11) use shaft hangers (6) or other
approved methods to stabilize the damper according
to instructions from structural engineer. NOTE! The fire
damper brackets (2) shall not be used for suspending
in the installation outside building elements.

8. Manual function testing of the motorized fire damper
can be performed with the tool delivered with the
actuator. When connected to a power supply, function
testing is done by using the switch of the thermal trip.
NOTE! If you open the damper blade manually with the
tool, be sure to release the damper back to the closed
position before switching on power.
9. The fixings used to secure the fire damper and ventila-
tion duct must have a fire resisting capacity that is at
least as high as the fire classification of the penetrated
building element (the fire resistance rating of a class
EI60 element is R60, etc.).
10. If the fire damper is used as an air transfer or air
terminal device, it must be equipped with a protective
grille. The distance between the grille and the damper
blade in the open position must be at least 30 mm. In
case of large fire dampers, an extension piece must be
installed between the grille and the damper blade.
