ATEX rated versions of fire dampers can be delivered with
Schischek 24 V / 230 V electric actuators that are rated for
installation in explosive atmosphere areas.
All fire dampers are tested according to the EN 1751 for
airtightness and retain class 2 leakage on the closed damper
blade and class C on the casing air leakage.
PRODUCT OVERVIEW
Fire dampers FD are used for prevention of fire spread trough the
ventilation ducts and between fire sections. Fire dampers consist
of steel sheet case, calcium silicate damper blade, damper blade
mechanism outside of the airflow and a manual or electric
actuator.
Fire damper case is made out of galvanized steel sheet. Variants
produced from stainless steel and powder coated steel are also
available. Calcium silicate blade is equipped with brass bearings
and seals made out of polyurethane and elastomer rubber.
Fire dampers FD25 are produced up to size 800x600 and have
25 mm thick damper blade. Fire dampers FD40 are produced in
sizes 800x600 up until 1500x800 and have 40 mm thick damper
blade.
FD25 fire dampers are equipped with R25 manual mechanism and
FD40 fire dampers are equipped with R40 manual mechanism.
Manual spring return mechanism is equipped with thermal fuse
that is triggered automatically when the temperature inside the
duct reaches 72 °C. It can also be activated manually by the
push of the button on the mechanism.
Additionalequipment for manual mechanism include end
con-tact switches for damper position signaling.
Fire dampers with electric actuators are equipped with
Belimo actuator drives in 24 V or 230 V versions.
Activation of fire dampers equipped with electric drives
can be via 72 °C or 95 °C thermal fuse or remotely via
control signal. Rearming of the electric fire damper can also
be done remotely via control signal. All electric actuators are
equipped with end switches for position signaling.

TESTS AND
CERTIFICATES
All our dampers are submitted to a number of tests by official
test institutes. Reports of these tests form the basis for the
approvals of our dampers. Klimaoprema fire dampers are
also suitable for installation in buildings with high hygienic
demands such as hospitals, clinics and pharmaceutical areas.
To confirm this, our products are tested in independent Institute
of Hygiene, based in Gelsenkirchen, Ruhr, and comply with
directives and guidelines in VDI 6022.
FIRE RESISTANCE
CLASSIFICATION
FD fire resistance is tested according to EN 1366-2 “Fire
resistance tests for service installations- Part 2: Fire dampers”.
Classification of the fire dampers is defined according to EN
13501-3 Fire classification of construction products and
building elements.
Installation in both, vertical and horizontal axis of rotation of the
dampers blade is acceptable (with the axis in vertical or
horizontal).
Fire resistance of fire damper depends on classification of walls
or ceilings. It is allowed to install products to walls or ceilings
only according to products Declaration of Performance. Walls
or ceilings with greater fire resistance can also be used. Fire
damper should be installed according installation manual which
can be found within this document.
Please consult latest Declaration of Performance on our
website:

R (R-S)
Manual operating mechanism, optionally with end switches (R-S). In case
of fire, the fire damper closes automatically. Damper closing can be initiated
either by thermal fuse melting, or by manual activation on the operating
mechanism. Upon closure, damper blade is locked in closed position and
can only be opened manually. Thermal fuse melting point is 72 °C.
M230-S
Belimo 230 V electro motor operating mechanism, comes with
integrated end switches. In case of fire, the fire damper closes
automatically. Damper closing can be initiated either by thermoelectric
release device or remotely by triggering the electro motor. Upon
closure, damper blade is locked in closed position and can be opened by
sending a signal to electro motor. Standard thermoelectric release point is
72 °C, optional 95 °C.
M24-S
Belimo 24 V electro motor operating mechanism, comes with integrated
end switches. In case of fire, the fire damper closes automatically.
Damper closing can be initiated either by thermoelectric release device
or remotely by triggering the electro motor. Upon closure, damper blade
is locked in closed position and can be opened by sending a signal to

Pressure drop values are described with the “Zeta” values for
each size. The exact pressure drop in [Pa] is calculated using
the following formula:
Pressure drop tables
Δp [Pa]= ζ * v² * 0,6
where ζis Zeta value from the tables below, v is airflow
velocity in [m/s]

The duct connected to the fire damper must be supported or
hung in such a way that the damper does not carry its weight.
The damper must not support any part of the surrounding
construction or wall which could cause damage and
consequent damper failure. It is recommended to connect the
damper to a flexible connection on either end of the damper.
The damper driving mechanism can be placed on either side of
the wall, however it needs to be placed so as to ensure
easy access during inspection.
•Mounting is possible with the blade axis in horizontal or in
vertical position
•The installation must comply with the tests that were
performed during certification
•Avoid any obstruction of the moving blade by the connected
ducts
•The class of air-tightness is maintained in case the installation
of the damper is made in accordance with the technical
manual
•Operating temperature: 50 °C max
•For indoor use only
The recommended / maximum installation opening is in the
table below. The smallest installation opening is where there
is enough space to install the seal!

All dampers can be installed with the blade axis in a horizontal
position or a vertical position in all installation types except
installation remote from the wall and battery installation.
The fire damper must be installed into a fire partition structure
in such a way that the damper blade in its closed position
is located inside this structure (except for installation with
Applique/MF1/MF2 installation frame).
To help you find the suspension plane, a bendable fixing bracket
is provided on the damper body (the use of bendable fixing
brackets is not required to meet the classification) and the red
tape is placed on the casing to mark the location of the wall
limit (distance from wall limit to the end of fire damper is 125
mm). This does not apply for Applique/MF1/MF2 kit installations.
Check the operation of the fire damper before commencing
the installation!
INSTALLATION
The FD25/FD40 fire d amper i s a lways t ested i n
standardized support frames (both in a concrete wall
and in a flexible wall) in accordance with EN 1366-2:
2015 table 3/4/5. The results obtained are valid for all
similar support frames which have a thickness and/or
density and/or fire resistance similar or greater
than the one tested.
Always ensure the damper is sufficiently supported
