DANGER!
Danger due to malfunction of the fire damper.
If the damper blade has been opened by means of
the crank handle (without power supply), it will no
longer be triggered by a temperature increase, i.e. in
the event of a fire. In other words, the damper blade
will not close.
To re-establish its function, connect the power
supply.

The damper blade is CLOSED
1. Insert the crank handle (1) into the opening for the
spring winding mechanism (the crank handle is
clip-fixed to the connecting cable).
2. Turn the crank handle in the direction of the arrow
(2) to just short of the travel stop.
3. Then quickly rotate the crank handle by
approx. 90° towards the 'lock' position .
ð
The damper blade remains in the OPEN posi-
tion.
4. Remove the crank handle.
