FGS Inspection
The FGS manual or actuator 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 FGS in any way nor perform any changes
to its structure without the manufacturer’s consent.
The operator performs regular checks of the FGS as per country established regulations, standards or at least once
every 12 months. The check needs to be performed by an employee who has been trained for this purpose by the
manufacturer following the “FGS Functionality Check”
procedure. The current FGS 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 from page 20 up to 22 of this
manual. Immediately after the installation and activation of the FGS, 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 is seen. On its external side, the damper housing and the activation mechanism are
checked. Through the removal of mesh a visual check of the FGS blades are to be checked. The FGS’s internal casing,
thermal fuse, sealing’s, foaming substance, the blades 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 foreign objects or a layer of impurities
present on the FGS.
Recommended Course of Action and Inspection Log as per EN 15 650:
1. FGS identication
2. Date of inspection
3. Checking of the electric connection of the activation mechanism (where applicable)
4. Checking of the FGS for cleanliness and possible need for cleaning (where needed)
5. Checking of the blades and sealing condition, possible correction and logging (where needed)
6. Checking of the proper re FGS closure – details can be found in the previous paragraphs
7. Checking of the FGS functionality – opening and closing using the control system, physical examination of the
FGS’s behaviour, possible correction and logging (where needed)
8. Checking of the end switches functionality in the open and closed position, possible correction and logging
(where needed)
9. Check whether the FGS remains in its standard operating position - open.
10. The FGS is usually part of a system. In that case the whole system needs to be checked as described in its
operation and requirements published by the builder of the system.
