1. Description
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.
Dampers have two inspection holes.

1.2 Working conditions
Right damper function is secured under the following conditions:
a) Maximum air circulation speed: 12 m/s
Maximum pressure dierence: 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.
2. Design
2.1 Design with mechanical control
Design .01
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 .11
Design .01 with mechanical control can be complemented with a limit switch signalling of the damper blade

2.2 Design with actuating mechanism
Design .40, .50
The damper are equipped by Belimo actuators with spring return and thermoelectric activation device of BFL,
BFN or BF depending on the damper size (furher mentioned as „actuators“).
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 120 sec. If the actuating power supply is cut o (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 o 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.
