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.
Damper blade automatically closes air duct using an actuating mechanism back spring. 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 bed in a material which enlarges its capacity and air proofs
the air duct.
Dampers have one inspection hole, since the shutting device and the inspection hole can be set
into the most advantageous position (with respect to the operation and manipulation with the
control device).
Damper characteristics
• CE certified acc. to EN 15650

• Classified acc. to EN 13501-3+A1
• Fire resistance EIS 60
• External Casing leakage class C, Internal leakage class 1 acc. to EN 1751
• Cycling test in class C 10000 acc. to EN 15650
• Corrosion resistant acc. to EN 15650
• Certificate of constancy of performance No. 1391-CPR-0090/2014
• Declaration of Performance No. CDM/FDMC/001/13

Working conditions
Right damper function is secured under the following conditions:
a) Maximum air circulation speed: 12 m.s
Maximum pressure difference: 1200 Pa
b) Dampers could be displaced into position “CLOSED” only in case that ventilator, or Air
Handling Unit is switched off. The goal is the securing of proper closing and safe
function of Fire Damper in case of Fire.
c) The air circulation in the whole damper section must be secured as steady on whole
surface.

Operation of the dampers does not depend on the direction of air circulation. The dampers can
be located in an arbitrary position.
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.
Temperature in the place of installation is permitted to range from - 20°C to + 50°C.
FDMC is always equipped by actuating mechanism BFL 24-T (further only "actuating mecha-
nism"). After being connected to power supply 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 140s. If the actuating power supply
is cut off (due to loss of supply voltage, activation of thermoelectrical actuating mechanism 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 16 s. 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 three 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-condition-
ing piping 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".

Weight and effective area
The Blade overlaps
For fire damper the open damper blade overlaps the damper body from dimension 250 by the
“a” value. These values are specified in the Tab. 3.2.1
Value has to be respected when projecting related air-conditioning piping.

The distance between the fire damper and the construction (wall, ceiling) must be minimal in
range from 10 to 50 mm. In case that two or more dampers are supposed to be installed in one
fire separating construction, the distance between the adjacent dampers must be at least 50 mm
Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages
of fire separating constructions. Damper assembly procedures must be done so as all load
transfer from the fire separating constructions to the damper body is absolutely excluded.
Back-to-back air-conditioning piping must be hung or supported so as all load transfer from the
back-to-back piping to the damper is absolutely excluded.
To provide needed access space to the control device, all other objects must be situated at least
350 mm from the control parts of the damper. Inspection hole must be accessible.
The control mechanism has to be protected (covered) against damage and pollution during
installation process.
All fire dampers has to be closed during installation process. The damper body should not be
deformed in the course of bricking in. Once the damper is built in, its blade should not grind on
the damper body during opening or closing.
Round dampers are with rubber tightness and glued all the way around.
