FUNCTIONAL TEST, MAINTENANCE/CLEANING, REPAIR
Impure and humid air may impair permanent operational sa-
fety. This is the reason why the function of all fire dampers
must be checked every six months after commissioning of
the ventilation system. If two consecutive functional tests
show no defects, the fire dampers only have to be tested at
a yearly interval. If maintenance agreements are made for
ventilation installations, it is recommended to include the
functional tests of the fire damper in these maintenance ag-
reements.
1. Manual trigger device
1.1. Visual inspection
Check the fire damper for damage and contamina-
tion (e.g. housing, damper blade, seals).
Perform necessary cleaning.
1.2 Manual triggering – Closing the fire damper
Pull manual unlocking disc (pos. 1) at the hand le-
ver (pos. 2), this removes the locking (in the open
position) of the locking bolt (pos. 4) in the trigger
device (pos. 3).
Hand lever has been released and is moved toward
the closed position by spring force.
ATTENTION! Do not reach into the pivoting range of the
damper blade and of the manual lever. There is a risk of in-
jury.
The fire damper must close and lock automatically
(locking of the damper blade in the closed positi-
on).
1.3 Opening the fire damper
Pull manual unlocking disc (pos. 1) at the hand le-
ver (pos. 2) and move it toward the trigger device
(pos. 3)
Locking bolt (pos. 4) must snap into the trigger de-
vice (pos. 3)
The fire damper is ready for operation again (dam-
per blade is locked in the open position).
S = Lubricate moving parts (bearing) only if they are not run-
ning smoothly (lubricant: free of resin and acid).
1.4 Replacing the fusible link (if necessary)
If the fusible link is damaged or corroded, for example, it
is necessary to replace it.
Perform manual triggering as described in section 1.2.
Unscrew the fastening screws (2 pieces, pos.5), pull the
release device out by turning it 90° and remove it from
the housing.
Compress the retainer screws of the fusible link holder
(pos. 7) using a suitable tool (e.g. pliers) and replace the
fusible link by a replacement fusible link (pos. 6).
Insert the release device and fasten it with screws (make
sure that the position of the coding screw with regard to
the coding hole is correct).
Finally a functional test has to be made.
