Entry into service and revisions
■
Before entering the dampers into operation after
assembly and after sequential revisions, checks and
functionality tests of all designs including operation of the
electrical components must be successfully provided and
finished. Check of thermal protective fuse and closing
mechanism. Check the closing function of the damper
blade. This can be done by removing of thermal fuse from
damper body. After entering into operation, these
revisions must be done according to requirement set by
national regulations.
■
In case that dampers are found unable to serve for their
function for any cause, it must be clearly marked. The
operator is obliged to ensure that the damper is put into
condition in which it is ready for function and meanwhile
he is obliged to provide the fire protection by another
appropriate way.
■
Results of regular checks, imperfections found and all-
important facts connected with the damper function must
be recorded in the "FIRE BOOK" and immediately repor-
ted to the operator.
■
Before entering the dampers with actuating mechanism
into operation after their assembly and by sequential
checks. Check of blade displacement into the breakdown
position "CLOSED" can be done after cutting off the
actuating mechanism supply (e.g. by pressing the RESET
button at the thermoelectrical starting mechanism BAT or
cutting off the supply from ELECTRICAL FIRE
SIGNALISATION). Check of blade displacement back into
the "OPEN" position can be done after restoration of
power supply (e.g. by releasing the RESET button or
restoration
of
supply
from
ELECTRICAL
FIRE
SIGNALISATION). Without power supply, the damper can
be operated manually and fixed in any required position.
Release of the locking mechanism can be achieved
manually or automatically by applying the supply voltage.
It is recommended to provide periodical checks,
maintenance and service actions on Fire Equipment by
Authorized persons. The authorized persons can be
trained by Producer, or by authorized Distributor. All
effective safety standards and directives must be
observed during fire damper assembly.
■
Visual inspection of proper damper integration, inside
damper area, damper blade, contact surfaces and silicon
sealing.
■
For regular or exceptional inspection of interior of fire
damper, micro-camera device can be used. On each fire
damper is inspection hole. In the case of inspection by
camera, take out the black rubber cap, insert the camera
inside the damper, check interior and at the end of
inspection, put the rubber cap back tightly to cover the
empty hole.
For dampers with mechanical control (designs .01, .11, .80), the following checks must be carried out
Check of closing mechanism and thermal fuse
To check the function of the mechanism proceed as follows:
■
Move the damper blade to "CLOSED" position as follows:
■
The damper is in "OPEN" position.
■
Press the control button of the mechanism to move the damper to "CLOSED" position.
■
Check the damper blade shift to "CLOSED" position.
■
Damper closing shall be sharp, the control lever shall be in „CLOSED“ position.
■
Move the damper blade to "OPEN" position as follows:
■
Turn the control lever by 90°.
■
The lever will automatically lock in "OPEN" position.
■
Check the damper blade shift to "OPEN" position.
■
Check of function and condition of the thermal fuse:
■
To check the function and the status of the fuse it's possible to remove the whole mechanism from the body of fire
damper which is attached to the damper's body with four screws M6.
■
Removing the thermal fuse from the fuse holder of initiation device, checks its correct functionality.
■
The mechanism is identified as M1 to M4, depending on the closing spring strength.
