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. The shutting spring is started by releasing an initiation lever. The impulse for
releasing the lever can be either a manual one, a thermal one or an electromagnetic one. 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.
rectangular dampers have two inspection holes.
Round 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).

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) 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 - 30°C to + 50°C.
Design with mechanical control
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 with mechanical control can be complemented with a limit switch signalling of the
damper blade position "CLOSED".

Design .01 with mechanical control can be complemented with initiation by means of an
electromagnet (solenoid). The voltage of the electromagnet (solenoid) can be AC 230V, AC/DC
24V. By voltage AC 230 V is damper equipped by electromagnet EM230. By voltage AC/DC 24
V is damper equipped by electromagnet EM230 with pre-pulse switch SIEM24. SEIM24 activates
the electromagnet after capacitor charge witch is placed inside of SIEM24. It takes about 10 sec.
Charging time depends on the current supply. For reliable operation is necessary connect to
electromagnet or pre-pulse switch appropriate supply for 20 to 30 sec. After activation of
electromagnet is released initiation lever and damper is closed. After activation is initiation lever
released. If is damper set up in position "OPEN" is necessary unlock initiation lever by pulling of
electromagnet core.

Product is designed to the Zone 2 with mechanical actuating mechanism and fusible link,
electromagnetic initiator (AC 230V) and auxiliary with end-switches (signalling the position of the
blade “Open” or/and “Close”). Such designs are the same as the designs .23, .24 and .83 and
they are adapted to fulfill the requirements of the usage in the Non- explosive environment.

FDMB is always equipped by electric actuating mechanism BFL, BFN, BF 230-T or BFL, BFN,
BF 230-T (further only "actuating mechanism"). After being connected to power supply AC/DC
24V or 230V, 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 140 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 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".
Signalisation of damper blade position "OPEN" a "CLOSE" is provided by two limit switches.
