Operations & Maintenance of fire dampers
Damper electrical function check
If the damper is in manufacture DV1÷DV6 with electromagnet it is necessary to test the mechanism function
also with electromagnet. Electromagnet receives the signal for actuating (for example from the central building
system) releases the actuating lever (4) and mechanism closes. Adjusting lever (1) immediately moves from
position OPEN to position CLOSED. If the damper is in manufacture with terminal switch (9) it must signal
closing the leaf after actuating the mechanism.
Dampers in basic version ZV and with additional manufacture DV1 ÷ DV6 (valid only for PK-I-R to
diameter 200 mm including)
Mechanical triggering
By pulling of securing part (2) we lock-off the adjusting lever of the mechanism (1) and we move it from the
CLOSED position to OPEN position. When turning the adjusting lever (1) it is simultaneously tensing also the
return- spring, that is why it is needed to use light power to tense the spring. Securing part must easily fit into
securing mechanism.

Wiring the electrical accessories
If a damper is equipped with electromagnet (8) or terminal switch (9) it is necessary to connect these devices
to el. power according to the wiring schemes.
Damper mechanical function check after putting it into operation
After putting the damper into operation (leaf opening) it is necessary to check damper function. By pulling the
securing part (2) adjusting lever releases (1) and moves from OPEN position to CLOSED position. Closing the
damper is provided by return-spring .Securing part (2) fits into holder and by that is the damper leaf secured
against opening. After actuating the damper immediately closes and the process of closing must be fluent
without the adjusting lever (1) stopping in any other position as CLOSED. If the damper is in manufacture with
terminal switch (9), by actuating the mechanism must the terminal switch (9) signal leaf closing.
By mechanical function damper check, please pull the actuating lever (4) with finger and pull your hand back
from the damper, so that it will not get injured by the main lever!
