Fire Damper ETCE and ETCS - Instructions for Installation, Operation and Maintenance

7. Check the functioning of the fire damper and proper
movement of the blade. Clean the damper, if necessary.
Place plastic covers on the openings and keep them
covered, until ducts are connected to the damper.
8. To reset the fuse mechanism: Turn the handle towards
the OPEN position until the mechanism clicks and the
blade locks into position.
9. Manual function testing of the motorized fire damper can
be performed with the tool delivered with the
actuator. When connected to a power supply, function
testing is done by using the switch of the thermal trip
(3). NOTE! If you open the damper blade manually with
the tool, be sure to release the damper back to the
closed position before switching on power.
10. Connect ducts to the damper according to the instruc-
tions provided by the designer and the manufacturer.
Access panel should be placed next to the fire damper
to enable necessary cleaning and inspection. Suspend
the ducts according to instructions from the manufac-
turer and ensure that the ductwork does not cause any
load on the damper installation.
11. If the fire damper is used as an air transfer or air termi-
nal device, it must be equipped with a protective grille.
The distance between the grille and the damper blade
in the open position must be at least 30 mm. In case of
large fire dampers, an extension piece must be installed
between the grille and the damper blade. A circular duct
of suitable length can be used as an extension piece.
12. When dampers are to be mounted next to one another,
the distance between the dampers should be
≥
200 mm
(Figure 8).
