1 Safety
1.1 General safety notes
Sharp edges, sharp corners and thin sheet metal
parts
CAUTION!
Danger of injury from sharp edges, sharp cor-
ners and thin sheet metal parts!
Sharp edges, sharp corners and thin sheet metal
parts may cause cuts or grazes.
– Be careful when carrying out any work.
– Wear protective gloves, safety shoes and a hard
hat.
Electrical voltage
DANGER!
Danger of electric shock! Do not touch any live com-
ponents! Electrical equipment carries a dangerous
electrical voltage.
– Only skilled qualified electricians are allowed to
work on the electrical system.
– Switch off the power supply before working on
any electrical equipment.
1.2 Correct use
The fire damper is used as an automatic shut-off
device to prevent fire and smoke from spreading
through ducting.
The fire damper is suitable for supply and extract air
in HVAC systems.
The use of the fire damper in potentially explosive
atmospheres is permitted with the corresponding
special accessories and a CE conformity state-
ment according to ATEX directive 2014/34/EU. Fire
dampers for use in areas with potentially explosive
atmospheres are marked for the zones for which
they have been approved.
The fire dampers may only be operated in com-
pliance with these installation instructions and the
technical data in these installation and operating
instructions.
Modifying the fire damper or using spare parts that
have not been approved by TROX is not permitted.
Additional provision for use in Germany:
Do not use it in extract air systems in commercial
kitchens.
For use as an air transfer damper see general type
approval Z-6.50-2516.
Use with a combined penetration seal requires indi-
vidual type-approval.
Use with firestop blocks requires individual type-
approval.
Crossflow fasteners may require a building inspec-
torate licence. This must be checked and applied for
by the client.
Flame-resistant, non dripping building materials
(elastomer foams) must at least comply with fire
rating class C - s2, d0 according to the German
MVV TB (2019/1) guideline. The applicable local
building regulations have to be observed.
Incorrect use
WARNING!
Danger due to incorrect use!
Incorrect use of the fire damper can lead to dan-
gerous situations.
Never use the fire damper:
– without specially approved attachments in areas
with potentially explosive atmospheres
– as a smoke control damper
– outdoors without adequate protection against the
effects of weather
– in atmospheres where chemical reactions,
whether planned or unplanned, may cause
damage to the fire damper or lead to corrosion

3 Supply package, transport
and storage
Scope of delivery
If attachments and accessories are supplied from the
factory with the fire dampers, they are already taken into
account in the order code.
Depending on the installation situation, supplementary
materials for assembly and fixing may be needed to
ensure proper installation, e.g. mortar, screws, mineral
wool, etc.
Such materials are not usually included in the supply
package (unless stated otherwise).
The selection of additional attachments or accessories
as well as the identification and provision of materials
for assembly and fixing is the responsibility of those
involved in the building project and must be done taking
into account the required classification.
Delivery check
Check delivered items immediately after arrival for
transport damage and completeness. In case of any
damage or an incomplete shipment, contact the ship-
ping company and your supplier immediately.
Fire damper
– Attachments/accessories, if any
Operating manual (one per delivery)
Colour hues on the damper blade
The blades of fire dampers are treated with a
greenish impregnating agent. Resulting colour hues
on the damper blade are due to technical reasons
and do not constitute a defect of any kind.
Transport on site
If possible, take the product in its transport packaging
up to the installation location.
Storage
For temporary storage please note:
Remove any plastic wrapping.
Protect the product from dust and contamination.
Store the product in a dry place and remote from
direct sunlight.
Do not expose the unit to the effects of weather (not
even in its packaging).
Do not store the product below -40 °C or above 50
°C.
Packaging
Properly dispose of packaging material.
