Operation Manual
After installation, it is necessary to adjust the damper into its operating position “closed”.
In case, that the damper is used for extraction of pollutants, adjust the damper into its operating position “open”.
Connect the actuator to the relevant electric power supply ( Fig. 20 up to Fig. 23)
The electromotor is activated and adjusts the damper into its operating position.
Smoke Control Damper Functionality Check
Switching the damper to the “open” position:
•
The blade must come to the fully open position within 60 seconds and must remain locked.
•
After reaching the end position of the blade, the appropriate signaling circuit must switch on
– wires S1 and S2 must be connected.
Switching damper to the “closed” position:
•
The blade must come up to the fully closed position within 60 seconds and must remain locked.
•
After reaching the end position of the blade, the appropriate signaling circuit must switch on
– wires S4 and S6 must be connected.
Smoke Control Damper Inspection
The actuator 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 or to 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 3 months.
The check needs to be performed by an employee who has been specifically trained for this purpose by the
manufacturer. The current damper condition evaluated during the inspection must be entered into the “Operating
Journal” 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 on page 46 of this user manual.
Immediately after the installation and activation of the damper, it must be checked under the identical conditions
as apply to the above mentioned 3-month inspections. On its external side, the damper housing and the actuator
movement are checked. Due to the need to perform a visual check of the damper’s internal parts, it is possible
to dismount the grille, which will enable access inside the damper or open
the inspection lid installed in the duct close to the damper.
The damper’s internal casing, sealings, 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.
NEVER OPEN THE INSPECTION LID WHEN THERE IS AIR FLOWING IN THE DUCT CONNECTED TO THE SMOKE
CONTROL DAMPER.
