■
Check the shift of the blade to "CLOSED" failure position after cutting off the power supply to the actuating mechanism (e.g.
by pressing the reset button on the thermoelectric starting mechanism BAT, by cutting off the power supply from electrical
fire signalization). Check the shift of the blade back to "OPEN" position by restoring the power supply to the actuating
mechanism (e.g. by releasing the reset button, by restoring the power supply from electrical fire signalization).
For the designs with actuating mechanisms, the following checks must be carried out
■
By cutting off and restoring the power supply, e.g. by a signal from electrical fire signalization.
■
Directly on the installed damper, with the help of the button on the thermoelectric starting mechanism BAT (simulating
fuse tripping).
The check of function of the damper with actuating mechanism can be carried out as follows
■
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 dampers should be moved to "CLOSED" position with the fan off or with closed regulation valve
situated between the fan and the fire damper.
Before putting the dampers into operation and during subsequent function checks, the following checks must be carried
out for dampers with optical smoke detector
Spare parts

Spare parts are supplied only on basis of an order.

Inspection hole disassembly
■
release the covering lid by turning the wing nut and
while turning the lid right or left release it from the
security belt. Then tilt the lid and remove it from its
original position.
■
If fuse Tf1 is initiated (duct outside temperature) than is necessary to change thermoelectrical starting mechanism
BAT72B-S
. Whereas is initiation temperature higher than actuator mechanism operating temperature
+50°C, recommended actuating mechanism manufacturer make complete revision or change actuating mechanism and
thermoelectrical starting mechanism.
■
If fuses Tf2/Tf3 are initiated (duct inside temperature) than it's possible to change only part ZBAT72
The check of function of the damper with actuating mechanism can be carried out as follows
■
Ensure each damper is fully checked for operational capa-
bility, control should be initiated from the control system
and/or with manual operation type (.01) Dampers blades
should open and close correctly and operation should be
visually inspected and documented prior to handover.
