Fire Dampers | 3 / 12
1396 - CPD - 0062
Fire damper is the closure for the HVaC ductworks so that the damper blade on the mechanical, thermal, or electrical
impulse close the duct and restrict the spread of re, heat and smoke. Explosion-proof version is modied by 2014/34/
EU directives, which set out the technical requirements for equipment and protective systems intended for use in
potentially explosive atmospheres - re dampers are in the design of group II category 2 G against the ignition of gas
explosion group IIB, temperature class T5 and Equipment Protection Level Gb according EN ISO 80079-36.2016.
Manually Operated Fire Dampers
In case of re, the re damper is automatically set to the closed position. Depending on the version, the damper closes
either after the thermal fuse melts or by means of activation in electromagnet in impulse connection, or disconnecting
the electromagnet in interrupted connection (see wiring diagrams in the Installation, operation and inspection manual of
the re dampers UserManual_PKIR_PKIS). After the closing of the damper blade, it is mechanically locked in the closed
position and can only be opened manually. The actuating mechanism is activated when the temperature of the air in the
duct reaches 74°C and the damper closes within 10 seconds after the fuse melts.
Actuator Operated Fire Dampers
The re damper can be equipped with a actuator which closes the damper after the command from the building
management system, or after the breach of the thermoelectric fuse. The actuator controlled re dampers are standardly
equiped with a thermoelectric fuse that activates the closing of the damper after reaching or exceeding of an ambient
temperature of 72°C, the actuator circuit is interrupted and the spring closes the damper blade within 20 seconds.
Pictures of the re dampers components and dimensions are available in the “DataSheet_PKIR_PKIS”
document on Systemair DESIGN.

Systemair DESIGN.
Design
Fire dampers have casings made from galvanized sheet metal, the blades from non-asbestos insulants have a cold
rubber seal and an intumescent one for a re situation.
Material Composition
The product contains galvanized sheet metal, calciumsilicate board, reproof carbon berglass, polyurethane foam
and ethylene - propylene rubber. These are processed in accordance with local regulations. The product contains no
hazardous substances, with the exception of the solder in the thermofuse, which contains a milligram of lead.
Connection of the Electrical Parts
Connection of all electrical parts according to the types of activation mechanisms is described in the Installation,
operation and inspection manual of the re dampers “UserManual_PKIR_PKIS” on
Systemair DESIGN.
Tightness of the Blade and the Casing of the Fire Damper
All rectangular re dampers have tightness of the blade and casing class 2C according to EN 1751.
On demand rectangular re dampers can be supplied with tightness class 3C. All circular dampers have standard
tightness class 3C.
Inspection Openings
Each Systemair re damper has a minimum one inspection opening:
