Before entering the dampers into operation after their assembly and by sequential checks, the
following checks must be carried out. Visual inspection of proper damper integration , inside
damper area, damper blade, contact surfaces and silicon sealing. 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.
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 author-
ized persons can be trained by Producer, or by authorized Distributor. All effective safety
standards and directives must be observed during fire damper assembly.
For regular or exceptional inspection of interior of fire damper, micro-camera device can be used.
On each fire damper is ispection 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:
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.
• To check the function and the status of the fuse is possible to remove whole mechanism from
the body of fire damper - mechanism is attached to the dampers body with four screws M6.
• Removing the thermal fuse from the fuse holder of initiation device, check its correct
functionality.
• The mechanism is identified as M1 to M5, depending on the closing spring strongness.
