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 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 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 the 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 damage on the inspected damper parts are seen. On its
external side, the damper housing and the activation mechanism are checked. Because of the need to perform a visual
check of the damper’s internal parts, the inspection lid should be opened. For small sizes there is the possibility of
removing the mechanism to perform the inspection. The removable mechanism always needs to be returned back into
the damper with the damper blade being closed.
The damper’s internal casing, thermal fuse, 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.
Recommended Inspection Steps According to the EN 15 650:
1. Damper identification
2. Date of inspection
3. Inspecting electric connection of the activation mechanism (where applicable)
4. Inspecting damper for cleanliness and possible need for cleaning (where needed)
5. Inspecting blade and sealing condition, possible correction and logging (where needed)
6. Inspecting proper fire damper closure
7. Inspecting damper functionality – opening and closing using the control system, physical examination of the
damper’s behavior, possible correction and logging (where needed)
8. Inspecting functionality of the end switches in the open and closed position, possible correction and logging (where
needed)
9. Inspect whether the damper is fulfilling its role as part of the regulation system (where needed)
10. Inspect whether the damper remains in its standard operating position.
11. The damper is usually part of a system. In that case, the whole system needs to be checked as described in its
operation manual and requirements published by the builder of the system.
