Warning

To avoid injury, make sure to wear gloves and keep the blades movement area clear while manipulating with the 
damper.NEVER OPEN THE INSPECTION LID WHEN THERE IS AIR FLOWING IN THE DUCT CONNECTED TO THE FIRE DAMPER!

Fire Damper Functionality Check

Manually Operated Activation Mechanism
1.Open the damper - turn the red crank (P10) using a hexagon bent wrench No. 10 (P13). Turn the red crank so that 
the indicator arrow is pointing to the “OPEN“ position (P11), the red crank needs to remain in the “OPEN“ position, and 
the microswitch for the open position indication must be pushed (if installed).2.Close the damper – release the 
mechanism by pressing the red release button (P9), the red crank will adjust its indicator arrow pointing to the 
“CLOSED“ position (P12) and remain locked in this position, the microswitch for the closed position indication must be 
pushed (if installed).3.Open the damper - turn the red crank (P10) using a hexagon bent wrench No. 10. (P13) Turn 
the red crank so that the indicator arrow is pointing to the “OPEN“ position, the red crank needs to remain in the 
“OPEN“ position, and the microswitch for the open position indication must be pushed (if installed).
Spring Return Actuator Operated Activation Mechanism
1.The fire damper must open automatically after the actuator circuit closes – the arrow on the actuator axis must show 
the position 90°.2.Press the control switch (P9) on the Thermoelectric fuse and hold it until the fire damper is fully 
closed – the arrow on the actuator axis must show the position 0°.3.Release the control switch on the Thermoelectric 
fuse. The fire damper must become fully open – the arrow on the actuator axis must show the position 90° - which is 
the operating position.

Operation Manual

After installation, it is necessary to adjust the damper into its operating position – open the fire damper.
Spring Return Actuator Operated Activation Mechanism
Connect the electric driving mechanism to the relevant electric power supply (see Electrical connection section). The 
electromotor is activated and adjusts the damper into its open position.
Manually Operated Activation Mechanism
Turn the red crank into the “OPEN“ position. The damper blade must remain in open position.

Damper Inspection

The activation mechanism keeps the dampers on stand-by during their entire life cycle in accordance with this manual 
issued by the manufacturer. It is not permitted to alter the dampers in any way nor perform any changes to their 
structure without the manufacturer’s consent. The operator performs regular checks of the dampers as per established 
regulations and standards at least once every 12 months. The check needs to be performed by an employee who has 
been specifically trained for this purpose. The current fire damper condition determined during the inspection needs to 
be entered into the operating logbook along with the date of the inspection, the legible name, surname and signature 
of the employee who performed the inspection. The Operating Journal includes a copy of the employee’s 
authorization. If any discrepancies are discovered, these need to be entered in the Operating Journal along with a 
proposal for their removal. The Operating Journal can be found in product documents section. Immediately after the 
installation and activation of the damper, it needs to be checked under the identical conditions as apply to the above 
mentioned 12-month inspections. The visual check ensures that visible damages on the inspected damper parts are 
seen. On its external side, the damper housing and the activation mechanism are checked. Due to the need to perform 
a visual check of the damper’s internal parts, open the inspection lid. For small sizes there is the possibility of 
removing the mechanism to perform the inspection. The removable mechanism always needs to be replaced into the 
damper with the damper blade being closed. The damper’s internal casing, thermal fuse, seals, foaming substance, the 
damper blade condition and accuracy of its closure during its leaning against the backstop in the closed position must 
all be checked. There must not be any strange objects or a layer of impurities from the air distribution systems inside 
the damper.
