Smoke dampers are installed in duct served for smoke outlet. Damper closes the smoke duct.

Dampers are installed in the position "OPEN". Dampers 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.

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 is

switched off. The goal is the securing of proper closing and safe function of Smoke

Damper in case of Fire.

c) The air circulation in the whole damper section must be secured as steady on whole

surface.

Damper characteristics

• Tested in accordance with EN 1366-2

• Classified acc. to EN 13501-3+A1 as E 30 ve, ho (i↔o) S or E 90 (ho i→o) or E 60 (ho i→o) S or

E 90 (ve i→o) S

• Fire resistance ES 30 (ES 60, E 90)

• ES Certificate of conformity No. 1391-CPR-2016/0083

• Declaration of Performance No. PM/DM-S/01/20/1

• Hygienic assessment of fire dampers - Report No. 1.6/pos/19/19b

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.

DM-S is always equipped by actuating mechanism BFL (BFN, BF) 24-T (further only "actuating

mechanism"). 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 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".

For round smoke damper the open damper blade overlaps the damper body from dimension

250 by the “c” or “a” and “c” values. These values are specified in the Tab. 3.2.1.

Value has to be respected when projecting related air-conditioning piping.

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.

The distance between the smoke damper and the construction (wall, ceiling) must be min. 75mm.

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 min. 200 mm according to EN 1366-2

paragraph 13.5.

The control mechanism has to be protected (covered) against damage and pollution during

installation process.

All smoke dampers have 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.

Installation opening dimensions

Dampers are with rubber tightness and glued all the way around.

Statement of installations

Examples of smoke damper installing

The smoke damper can be installed into a solid wall construction made e.g. of normal

concrete/masonry, porous concrete with minimum thickness 100 mm or into solid ceiling
