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.

• 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.
