Installation
•
FR90 fire dampers, series FR92K, must be installed
according to the instructions in this user manual.
Structural requirements for walls, ceilings, ventilation
ducts etc. must be met by the customer.
The technical regulations and national statutory
regulations must be observed during installation.
In Germany, this means the “Technical Building
Regulations” (VV TB) and the “Guideline on Fire
Protection Requirements Pertaining to Ventilation
Systems” (Lüftungsanlagenrichtlinie - LüAR).
•
FR90 fire dampers, series FR92K, may be connected
to ventilation ducts made of non-combustible and
combustible materials. Thermal expansion in case
of fire must not subject the fire dampers to notable
forces. Compensatory measures must be provided as
required. In general, the compensation is achieved by
routing ducts appropriately.
•
FR90 fire dampers, series FR92K

materials.
•
Are suitable for all installation positions.
•

also in metal stud walls.
•

Maintenance-free
•
FR90 fire dampers, series FR92K, are maintenance-
free as a result of the full enclosure, corrosion-resistant
materials and precise manufacture.
The stainless steel operation mechanics are situated in
an enclosure, not in the air flow. There is no requirement
for recurrent cleaning and lubrication.
Damper blades are break-proof. Seals and other
materials are engineered to be durable.
Functional testing and servicing
•
Fire dampers must be maintained by the owner.
Functional checks should be performed periodically
and depend largely on operation of the system. The
regulations must be adhered to.
•
Repairs or service work are required in the event of
malfunctions. Original spare parts must be used.
•
Cleaning work required in ventilation systems for
hygiene reasons must be performed in an operation-
dependent manner, and also includes the fire dampers.
