■
Before putting the damper into operation, serviceability
checks and functional tests must be carried out including
testing of functionality of all electrical elements. After
putting into operation these serviceability checks must be
carried at least twice a year. If no defect is found during
two subsequent serviceability checks, these checks can be
carried out once a year.
■
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
allimportant facts connected with the damper function
must be recorded in the "FIRE BOOK" and immediately
reported to the operator.
■
Before entering the dampers with actuator into operation
after their assembly and by sequential checks. Check of
blades 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 blades
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 blades, contact surfaces and silicon
seal.
Commissioning and revisions
■
Check the rotation of the blades to "CLOSED" failure position after disconnection the power supply of the actuator (e.g. by
pressing the test button on the thermoelectric activation device BAT or by disconnection the power supply from electrical
fire signalization). Check the rotation of the blades back to "OPEN" position by restoring the power supply to the actuator
(e.g. by releasing the test button or by restoring the power supply from electrical fire signalization).
Following checks must be carried out for all dampers
■
The function checks of the optical smoke detector are to be carried out by employees of an authorized organization who
have corresponding electrotechnical qualification and have been properly trained by the manufacturer. The function
checks are to be carried out as a part of function checks of the fire dampers, at least 1x a year.
■
For the function checks, the damper blades should be in "CLOSED" position with the fan off or with closed air regulation
situated between the fan and the fire damper.
Following checks must be carried out for dampers with optical smoke detector
■
If the thermal fuse
Tf1
is interrupted (due to temperature outside the duct), it is necessary to replace the spring return
■
If the thermal fuse
Tf2
is interrupted (due to temperature inside the duct) , only the spare part ZBAT 72 (95/120/140) needs
to be replaced (acc.to the activation temperature).
How to proceed after Tf1 or Tf2 fuses have been activated
