Fire damper - FDMR
TPM 140/19
■
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 fuse and actuating mechanism.
Check the closing function of the damper blade. This can
be done by removing the thermal fuse from the damper
casing. 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 actuator into operation
after their assembly and by sequential checks. Check of
blade rotation into the breakdown position "CLOSED" can
be done after disconnecting the actuator supply (e.g. by
pressing the test button at the thermoelectric activation
device BAT or disconnecting the supply from ELECTRICAL
FIRE SIGNALISATION). Check of blade rotation back into
the "OPEN" position can be done after restoration of
power supply (e.g. by releasing the test 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 installation, inner area
of a damper, damper blade, contact surfaces and silicon
seal.
■
For regular or exceptional inspection of interior of fire
damper, micro-camera device can be used. On each fire
damper is an inspection opening. 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 manual control (designs .01, .11, .80), the following checks must be carried out
Check of a manual control and thermal fuse
To check the function of the manual control proceed as follows:
■
Turn the damper blade to "CLOSED" position as follows:
■
The damper blade is in "OPEN" position.
■
Press the control button of the manual control to turn the damper blade to "CLOSED" position.
■
Check the damper blade rotation to "CLOSED" position.
■
Damper blade closing shall be smooth and fast, the control lever shall be in „CLOSED“ position.
■
Turn the damper blade to "OPEN" position as follows:
■
Turn the control lever by 90°.
■
Check the damper blade rotation to "OPEN" position.
■
The lever will automatically lock in "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 manual control from the casing of the fire
damper which is attached to the damper casing with four screws M6.
■
Removing the thermal fuse from the fuse holder of a manual control, checks its correct functionality.
■
The manual control is identified as M1 to M5, depending on the closing spring strength.
