Description
Working conditions
■Exact damper function is provided under the following conditions
■maximum air velocity 12 m/s
■underpressure max. -1200 Pa
■the air circulation in the whole damper section must be secured as steady on whole surface.
■Dampers can be installed in position with horizontal or vertical blade axis.
■Dampers can be installed in position with actuating mechanism on top or on the side of damper.
■Dampers are suitable for systems without abrasive, chemical and adhesive particles.
■Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3, class 3K22.
■Temperature in the place of installation is permitted to range from -30°C to +50°C.
Fire dampers are shutters in ducts of air-conditioning devices
that prevent spreading the fire and combustion products
from one fire segment to the other one by means of closing
the duct in the points of fire separating constructions.
Dampers blade automatically closes air duct using a shutting
spring or an actuating mechanism back spring. Closing spring
is released either by pushing of the button or by thermal fuse.
The back spring of the actuating mechanism is started when
the thermoelectrical starting mechanism BAT is activated,
when a reset button on BAT is pushed or when a power
supply of the actuating mechanism is stopped.
The damper is sealed with a silicon packing against smoke
penetration after closing the blade. At the same time, the
damper blade is bedded in a material which enlarges its
capacity and air proofs the air duct.
Dampers have two inspection holes.

Design with mechanical control
■Design .01 with mechanical control can be complemented
with a limit switch signalling of the damper blade position
"CLOSED".
■Cable is connected directly to limit switch.
■Limit switch detail → see page 5
Design .11
■Design .01 with mechanical control can be complemented
with a terminal switches signaling of the damper blade
position "CLOSED" and "OPEN".
■Limit switches are connected via damper casing, cables
are connected directly to limit switches.
■Limit switch detail → see page 5
Design .80
■Design with mechanical control with a thermal protective
fuse which actuates the shutting device, after the nominal
start temperature 72°C has been reached.
■Automatic initiation of the shutting device is not activated
if the temperature does not exceed 70°C.
■In case that other start temperatures are required,
thermal fuses with nominal start temperature +104°C or
+147°C can be supplied (this requirement must be
specified in the order).
Design .01
ATTENTION:
■Mechanisms are produced in five designs M1 to M4, dif-
ference is only in size of inner spring, which closes the fire
damper.
■For the size of fire dampers is always assigned the size of
mechanism → see pages 14 to 19
■It is not recommended to use different size of mechanism,
than given by the manufacturer, otherwise, there is a risk
of fire damper destruction.

Design with actuating mechanism
■The dampers are equipped by Belimo actuators with
spring return and thermoelectric activation device of BFL,
BFN or BF depending on the damper size (further mentio-
ned as „actuators“).
■After being connected to power supply 230V or AC/DC
24V, the actuating mechanism displaces the damper
blade into operation position "OPEN" and at the same
time it pre-stretches its back spring.
■When the actuating mechanism is under voltage, the
damper blade is in the position "OPEN" and the back
spring is pre-stretched.
■Time needed for full opening of the flap blade from the
position "CLOSED" to the position "OPEN" is maximum
120 sec. If the actuating power supply is cut off (due to
loss of supply voltage, or pushing the reset button on the
thermoelectrical starting mechanism BAT), the back
spring displaces the damper blade into the breakdown
position "CLOSED".
■The time of displacing the blade from the position "OPEN"
to the position "CLOSED" takes maximum 20 sec.
■In case that the power supply is restored again (the blade
can be in any position), the actuating mechanism starts to
re-displace the damper blade into the position "OPEN".
■A thermoelectrical starting mechanism BAT, which
contains two thermal fuses Tf1 and Tf2, is a part of the
actuating mechanism.
■These fuses are activated when temperature +72°C has
been exceeded (the fuse Tf1 when the temperature
around the damper and the fuses Tf2 when the
temperature inside the air-conditioning ducting has been
exceeded).
■After the thermal fuse Tf1 or Tf2 has been activated, the
power supply is permanently and irreversibly cut off and
the actuating mechanism, by means of the pre-stretched
spring, displaces the damper blade into the breakdown
position "CLOSED".
■Signalisation of damper blade position "OPEN" a "CLOSE"
is provided by two limit switches.

Thermoelectrical starting mechanism BAT
■If the thermal fuse Tf1 breaks (for a temperature close to
the fire damper), it is necessary to replace the actuating
mechanism. Thermoelectric starting mechanism BAT is
integral part of the actuating mechanism.
■If the thermal fuse Tf2 (for temperature in the duct) is
interrupted, it is enough to replace only the spare part
ZBAT72.
■When one of the thermal fuses responds, the supply
voltage is interrupted permanently and irreversibly.
■The function (interruption of the supply voltage) can be
checked by pressing the test button.
■Installation is carried out with the pre-assembled, self-
drilling and self-tapping screws.

FDMB - Fire damperPage 20 Version 2022-12-20
TPM 164/22
■The fire dampers are suitable for installation in arbitrary
position in vertical and horizontal passages of fire separ-
ating structures. The damper assembly procedures must
be done so that all load transfer from the fire separating
constructions to the damper body is absolutely excluded.
The back-to-back air-conditioning ducting must be susp-
ended or supported so that all load transfer from the
back-to-back ducting to the damper flanges is absolutely
excluded. The gap between the installed damper and the
building structure must be perfectly filled with approved
material all over its volume.
■To provide the necessary space for access to the control
device, all other items must be situated at least 350 mm
from the control parts of the damper. At least one inspec-
tion hole must be accessible.
■The damper must be installed so that the damper blade
(in closed position) is situated in the fire separating
structure - marked by the label BUILT-IN EDGE on the
damper body. If such solution is not possible, the ducting
between the fire separating structure and the damper
blade must be protected according to the certified install-
ation method → see pages 22 to 34
■During the installation and plastering process, the control
mechanism must be protected (covered) against damage
and pollution. The damper body should not be deformed
during bricking in. Once the damper is built in, the damper
blade should not grind on the damper body during
opening or closing.
■The distance between the fire damper and the structure
(wall, ceiling) must be 75 mm at the minimum. If two or
more dampers are to be installed in one fire separating
structure, the distance between adjacent dampers must
be 200 mm at the minimum, according to EN 1366-2.
The distance between the fire damper and the construction
■minimum distance 200 mm between dampers installed in the duct;
■minimum distance 75 mm between damper and construction (wall/ceiling).
■This is the EN 1366-2 test standard distances. They are
considered as minimum. Actual location should be
based on wall manufacturers requirements.
■Always consult the wall manufacturers specific guide-
lines for deflection heads, penetration size, location to
other services, fire stopping and load bearing capacity.
■No other services should pass through the dampers
building work opening.
■For lightweight walls always consult the wall manufac-
turer specific guidelines for penetrations sizes and dis-
tances.
