• Actionair ThermShield FD
• Actionair ThermShield FD-C
Health and safety
• This process must be undertaken by competent
persons. More than one person may be required to
ensure the safe handling of large dampers and other
materials. Use must be made of access equipment to
ensure unsafe practices are not used to approach walls
or difcult access areas.
• Standard site PPE should be used (minimum steel toe
cap boots, hard hat); together with any protective
eyewear, gloves and masks, when drilling or cutting is
being undertaken. The latter should also be used when
handing the wall construction materials, as dened by
the material suppliers. If loud equipment is being used,
hearing protection should be used.
• All waste materials should be collected and disposed of
as dened by the relevant supplier.
• Actuators: All wiring should be carried out in
accordance with the wiring details provided by the IEE
and BS regulations and by a competent person. Care
must be taken when installing and inspecting dampers,
as they are likely to close without warning due to
loss of electrical power or a temperature rise in the
ductwork. This is their prime function. Do not insert
any items, ngers or limbs between the blades. Larger
dampers must be handled in accordance with current
regulations and good practice due to weight.

• For full classications please refer to our Declaration
of Performance (DoP), which can be found on our
website.
• The methods in this manual should be followed to
ensure a CE-marked installation.
• The instructions are based on the tested method using
Actionair ThermShield PTC re/smoke dampers.
• Our ThermShield dampers are designed to be
used with re separating elements to maintain re
compartments. The ThermShield is an actuated failsafe
close damper with low smoke leakage, often referred
to in the industry as a Fire/Smoke damper.
• Under the Fire Damper Product standard BS EN 15650
our Fire Damper products are tested to BS EN 1366-2
and classied under BS EN 13501-3.

Fire damper installation
square openings
The FD25 / FD40 re damper is always tested in
standardised support frames (both in a concrete wall and
in a exible wall) in accordance with EN 1366-2: 2015
table 3/4/5. The results obtained are valid for all similar
support frames which have a thickness and / or density
and / or re resistance similar or greater than the one of
the tests.
The duct connected to the re damper must be
supported or hung in such a way that the damper does
not carry its weight. The damper must not support
any part of the surrounding construction or wall which
could cause damage and consequent damper failure. It
is recommended to connect the damper to a dilatation
compensator on either end of the damper.
The damper driving mechanism can be placed on either
side of the wall, however it needs to be placed so as to
ensure easy access during inspection.
The gap in the installation opening between the re
damper and the wall/ceiling can be increased by up
to 50% of the gap area, or decreased to the smallest
dimension (B + 60 x H + 60)
• The installation must comply with the tests that were
performed during certication
• Avoid any obstruction of the moving blade by the con-
nected ducts
• The class of air-tightness is maintained in case the
installation of the damper is made in accordance with
the technical manual
• General operating temperature: 50 °C max
• For indoor use only
All dampers can be installed with the blade axis in a
horizontal position or a vertical position in all installation
types except installation remote from the wall and battery
installation. The re damper must be installed into a re
partition structure in such a way that the damper blade
in its closed position is located inside this structure.
To help you nd the suspension plane, a bendable xing
bracket is provided on the damper body and the red tape
is placed on the casing to mark the location of the wall
limit (distance from wall limit to the end of re damper
is 125mm). This does not apply for Applique / MF2 kit
installations.
Check the operation of the re damper before
commencing the installation!

Mounting is possible with the blade axis in horizontal or
in vertical position

Avoid any obstruction of the moving blade by the
connected ducts
The class of air-tightness is maintained in case the
installation of the damper is made in accordance with the
technical manual
General operating temperature: 50 °C max.
For indoor use only
The gap in the installation opening between the re
damper and the wall/ ceiling can be increased by up
to 50% of the gap area, or decreased to the smallest
dimension that is shown in the table:
Damper size - Ød [mm] Opening size - A (minimum)
Ød ≤160 Ød + 85 mm
180 ≤Ød ≤315 Ød + 75 mm
355 ≤Ød ≤ 450 Ød + 65 mm
Ød > 450 Ød + 55 mm
Installation in both, vertical and horizontal axis of rotation
of the dampers blade is acceptable (with the axis angle
0 - 360°).
The re damper must be installed into a re partition
structure in such a way that the damper blade in its
closed position is located inside this structure (except for
installation with MF installation frame).
To help you nd the suspension plane, a bendable hinge
is provided on the damper body and the red tape is
placed on the casing to mark the location of the wall
limit (distance from wall limit to the end of re damper
is 215mm). This does not apply for Applique/ MF1/ MF2
kit installations. Check the operation of the re damper
before commencing the installation!

Flexible Wall Subframe
When installing the re dampers in the exible walls it
is necessary to make a metal subframe onto which the
damper will be xed with screws. Subframe should be
prepared according to the drawings below.
Support for Installation with Mortar
In re damper installations with mortar, it may be
necessary to use wooden supports to prevent the casing
from deforming while mortar is getting hardened.
Before lling the gap between wall and re damper, close
the damper blade and install the wooden supports as
seen in the drawings below.
Place the wooden support as close as possible to the re
damper blade!
