1. Description

1.1 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. 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.

1.3 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).

Fig. 3 Design .01

Design .11

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.

Fig. 4 Design .11

ATTENTION:

Mechanisms are produced in four designs

M1 to M2 , dierence 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 - Tab 4.2.1. It is not

recommended to use dierent size of mecha-

nism, than given by the manufacturer, other-

wise, there is a risk of ﬁre damper destruc-

tion.

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.
