COMMISSIONING AND MAINTENANCE
COMMISSIONING
Before the ventilation and air-conditioning system and thus
also the fire dampers are put into operation for the first
time, they must undergo an inspection in order to determine
and assess the installation and function (see model protocol,
page 25).
FUNCTIONAL CHECKING, CLEANING, REPAIR
The owner or operator of a ventilation and air-conditioning
system must arrange for its function to be checked. The in-
spection must be carried out at least every six months. If two
successive functional tests at intervals of half a year do not
reveal any defects, the interval may be increased to one year.
The following standards describe the basic maintenance
measures and are generally to be taken into account:
- EN 13306
- DIN 31051
- EN 15423
In addition, any possible national or building code regulations
regarding the safe operation of ventilation and air-condition-
ing systems must be observed.
1. Manual trigger device
1.1. Visual inspection
Check the fire damper for damage and contamination
(e.g. housing, damper blade, seals).
Perform necessary cleaning work.
1.2 Manual release
–
Closing the fire damper
Pull the manual unlocking disc (pos. 42) at the hand lever
(pos. 3), thus releasing the lock (in the "OPEN" position)
of the locking bolt (pos. 44) in the trigger (pos. 5).
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 (lock-
ing of the damper blade in the CLOSED position).
1.3 Opening the fire damper
Pull manual unlocking disc (pos. 42) at the hand lever (pos.
3) and move it toward the trigger device (pos. 5)
Locking bolt (pos. 44) must snap into the trigger device
(pos. 5)
The fire damper is ready for operation again. (Damper
blade is locked in the "OPEN" position).
When the fusible link becomes damaged, its replacement
must be carried out as follows.
If, for example, the fusible link is damaged or corroded, it
is must be replaced.
Perform manual release as described in section 1.2.
Unscrew the fastening screws (pos. 43; 2 pieces), 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. 45) 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 check has to be carried out.
