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.

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. Recommendation is at least once every 6 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.
Immediately after the installation and activation of the damper, it must be checked under the identical conditions as
apply to the above mentioned six-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 body extension fitted with the grille, which will enable access inside the damper or open the inspection
lid if the damper is equipped with one. 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 DAMPER.

Recommended Course of Action and Inspection Log as per EN 12 101

1.Identification of damper
2.Date of inspection
3.Check actuator wiring for damage
4.Check the wiring of the end switches for damage
5.Check the damper cleanliness and clean where necessary
6.Check the inspection lid, cover tightness
7.Check the blade and sealings, and correct and record where necessary (where applicable)
8.Check the damper functionality (open and close) as per the “Smoke Damper Functionality Check” chapter and
confirm operation by using the control system, tracking the physical behavior of the damper and signalization of the
end positions, and correct and record where necessary (where applicable).
9.The damper is part of the SHEVS. Therefore, the complete system must be checked as specified in its operational and
maintenance requirements.
10.Set into the operating position – as per the “Operation Manual”.
11.Record the result into the “Operating Journal” with the name and signature of the Inspection Technician.
