ACCESSORIES AND PRODUCT MODELS
ACCESSORY CODE DESCRIPTION
Mesh on one side N1 galvanised steel
Mesh on both sides N2 galvanised steel
Fuse (manual) FU Thermal release at 50, 65,
72, or 100 ºC
Microswitch MS Closed position indication,
enclosure class IP 65
The manual fire damper can be equipped with a
bipolar microswitch, MS, which indicates the closing
of the shutoff blade. The microswitch has potentialfree
points (no = normally open and nc = normally
closed), which can be used to control other fire
dampers equipped with an electric release, e.g.,
triggering an alarm in the fire suppression system. The
maximum operating voltage and current is 400 V, 10 A.

RELEASE TYPES (manual actuator)
The manual fire damper has always a thermal release
operation via a thermal a fuse. Additional release
systems available:
• Solenoid operation, providing a possibility for
electric signal release
• Electromagnetic release
• Pneumatic release with pressurised gas (e.g., CO2)
Solenoid operation
The manual fire damper can be released using
solenoid, by switching on the solenoid operating
voltage. The release can be initiated by e.g. a smoke
detector, microswitch, pressure switch or similar,
which connects the power supply via e.g. an auxiliary
relay.

Electromagnetic operation
The fire damper stays open when the electrical circuit
is closed. The fire damper is shut by opening the
circuit.
Note: Interruption of the power supply closes the
damper. Uninterrupted power supply (e.g., a battery
backup system) is recommended.
Option
EM
Pneumatic release
The manual fire damper can be released by
a pneumatic release, connected to e.g. a fire
suppression system. When the system is activated,
pressure acting on the pneumatic cylinder releases
the spring, closing the fire damper. The actuator is
suitable for common pressure levels used in fire
suppression systems. The lowest operating pressure
of the actuator is 200 kPa.

Function
The FDI is a circular fire damper, which prevents
fire and smoke from spreading in the ductwork of
ventilation and air conditioning systems.
The FDI is approved for horizontal and vertical
installation in heavy and light-weight structures
fulfilling the fire resistance class EI 60 (ve,ho,io)
S requirements. It is also approved for horizontal
installation in concrete floors/ceilings to fulfill fire
resistance class E 90 (ho,io) S requirements.
The fire damper is equipped with either manual or
electric actuators. All models are equipped with a
thermal fuse and a visual position indicator. The fuse
responds to a rise in temperature, closing the springreturn
blade.
Alternatively, the damper may be released by a
system using an electric actuator or release systems
that are available as accessories to the manual
actuator (solenoid, electromagnetic, or pneumatic).
If the power in the motorised actuator system is
switched off, the blade is automatically closed by a
springreturn actuator.
A double-sealing solution closes the duct, effectively
preventing the spreading of fire gases in the
ventilation ductwork when the fire damper closes. The
flexible seal of the double-sealing system operates
at lower temperatures, while the graphite mass seal
expands to insulate the system at temperatures above
150 ºC.
The nominal release temperature of the fuse with an
electric actuator is 72 °C. Fuses with optional release
temperatures 50, 65, 72 and 100 °C are available for
the manual actuator.
The fire dampers equipped with electric actuators are
released by switching off the power supply.
The FDI fire damper is recommended to be connected
to the MSH Fire Damper Management System. The
MSH system enables the use of smoke detectors in
ductwork or room spaces. The FDI fire damper can
also be connected to other commonly used building
automation systems.

Installation
The fire damper is installed on concrete or masonry
walls and ceilings and on lightweight walls.
An opening is always left in the separating element
for the casing of the product to be led through the
structure. The maximum diameter of the installation
hole is the fire damper diameter D + 20 mm.

To make installation easier, all products come with an
installation/casting frame, which is used to fasten the
fire damper to the wall surface or the steel frame of
the plasterboard wall.

The installation is finished by filling the casting frame
from the front of the device with a gypsum-based
firestop mastic that is tested for use for this purpose
(such as GBG, from Palokatkomiehet Oy; CB 637, from
Hilti; and FIREBREAK COMPOUND, from Würth).

During installation, the fire damper and actuator must

be protected with, e.g., a plastic cover.
The correct operation of the fire damper must be
ensured both before and after grouting. Setting of the
damper is performed from outside the device.

installer’s installation certificate form, are supplied
with each product. See also the section ‘Documents /

INSTALLATION OF MODULES
Two fire dampers can be installed using the same
screws on one side such that the lip of the installation
frame of the lower damper is either flattened or
removed, and the casting is spread uninterrupted
from one outside end to the other. See the installation
instructions.

Servicing
A manual fire damper can be reset after the fuse
temperature has fallen below the release temperature.
If the shutoff blade does not lock, the fuse is worn out
and must be replaced. The fuse can be changed from
outside the fire damper.
The fuse of a fire damper equipped with an electric
actuator must be replaced if the fuse has been
released because of a rise in temperature.
To ensure proper operation of fire dampers, they
should be inspected regularly. The minimum
recommended inspection period is one year or
according to the building code It is recommended
that the fire damper is connected to automatic fire
damper management system MSH (operating voltage
24-VAC).
Upon failure during testing of the fire damper,
maintenance service shall be ordered from an
authorised Halton representative to ensure appropriate
operation of the product.

double-sealing solution that ensures fire-gas tightness
and fire resistance both at room temperature and in
high temperatures when the fire damper is closed.
In motorised models, the fuse shall be activated at 72
°C.
In the manually operated model, the fuse activation
temperature corresponds to the specifications (50, 65,
72, or 100 °C).
The fuse shall be located inside the damper, and it
shall be possible to replace it from the outside.
The fire damper shall have means for external opening
/ triggering of the release and closing.
The fire damper shall include a position indicator.
Where indicated, the manually operated fire damper
shall be supplied with the following release options:
• Electric signal release by closing circuit (initiated
by, e.g., a smoke detector or a microswitch or
pressure switch); the enclosure class of the
electric release arrangement shall be IP54 or better.
• Electromagnetic release by opening circuit.
• Pneumatic release.
20/FDI/0000/0608/EN
