For the designs with actuating mechanisms, the following checks must be carried out:
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).
The check of function of the damper with actuating mechanism can be carried out as follows:
a) by cutting off and restoring the power supply, e.g. by a signal from electrical fire signalization
b) directly on the installed damper, with the help of the button on the thermoelectric starting
mechanism BAT (simulating fuse tripping).
Before putting the dampers into operation and during subsequent function checks, the following
checks must be carried out for dampers with optical smoke detector.
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
provably 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.
Spare parts are supplied only on basis of an order.
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 is possible change only part ZBAT72
or ZBAT95 (according initiating temperature).
