ThermShield Standard Installation Method

Applies to...
• Actionair ThermShield FD
Health and safety
• This process must be undertaken by competent per-
sons. More than one person may be required to ensure
the safe handling of large dampers and other materi-
als. 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 accor-
dance 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 regula-
tions 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 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.

ThermShield Standard Square/Rectangular Installation Guide
Fire damper installation
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 exible
connection 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!

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 setting.
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!
Ensure that the damper is sufciently supported!

Periodic Maintenance
Manufacturer Recommended Service
Intervals
• After commissioning and handover (see DW145 check
sheet), in order to remain compliant with 15650:2010,
we recommend that you follow a regular service and
inspection programme to ensure correct operation
of dampers in the event the damper is required to
actuate.
• In addition to regular physical inspections (in
accordance with 15650:2010) we recommend using a
dedicated damper control panel with a digital reporting
mechanism (such as an Actionpac LNS system) to
frequently monitor and report on regular remote
damper testing.
• Ensure maintenance is performed in line with the latest
best practice and relevant local or specialist guidance.
• Our recommended service intervals for life safety
products are as follows:

cable) for Damage

BS EN 15650:2010 - Ventilation for Buildings
- Fire Dampers
• Section 8.3 states regular testing/ inspection should
be undertaken to meet regulatory requirements, or at
intervals not exceeding six months.
• A comprehensive example of the maintenance
procedure is given in Annex D of the standard. Some
automatic systems may allow more frequent testing
(48hr or less) and this may be required by a national
standard.
Approved Document B, Volume 2
• Clause 10.12 states adequate means of access must be
provided to allow inspection, testing and maintenance
of both re damper and its actuating mechanism.
BS 9999:2017 - Code of Practice for the Fire
Safety in the Design, Management and Use
of Buildings - Annex I
Smoke Control Systems
• For means of escape states actuation of the system
should be simulated once a week. It should be ensured
that any fans and powered exhaust ventilators operate
correctly, smoke dampers close (or open in some
systems), natural exhaust ventilators open, automatic
smoke curtains move into position, etc.
Three Monthly
• In addition to the checks recommended in V.2, V.3 and
V.4, the actuation of all smoke control systems should
be simulated once every three months. All zones should
be separately tested and it should be ensured that any
fans and powered exhaust ventilators operate correctly,
smoke dampers close (or open in some systems) etc.
Yearly
• In addition to the following checks should be made
for annual inspections and tests of the following to
be carried out by competent persons, for any defects
to be logged and the necessary action taken, and for
certicates of testing to be obtained.
– Fire detection and re alarm systems;
– Self-contained luminaires with sealed batteries, if more
than 3 years old;
– Sprinkler, drencher and watermist systems;
– Smoke ventilators and smoke control systems;
– Fire dampers
BS 9999:2017 - Code of Practice for the Fire
Safety in the Design, Management and Use
of Buildings - Annex W
• Maintenance of air conditioning and ventilation
equipment including air lters, motors, re dampers
and their controls, smoke detectors and alarms is
of paramount importance both in preventing re
and in ensuring that measures taken to mitigate
its consequences are effective when needed.
Arrangements should be made for all re dampers to
be tested by a competent person on completion of the
installation and at regular intervals not exceeding 2
years. They are to be repaired or replaced immediately
if found to be faulty. Spring operated re dampers
should be tested annually and re dampers in dust
laden and similar atmospheres should be tested much
more frequently, at periods suited to the degree of
pollution.
