Description
Fire dampers represent passive fire protection, designed with the help of compartmentalization to prevent the spread
of toxic gases, smoke and fire. Standard fire dampers are designed and certified in accordance with EN 15650 and
tested for EIS criteria according to EN 1366–2. Fire damper together with its installation form an inseparable part of fire
resistivity rating. FDR-3G fire dampers are designed for the installations listed and described in their User Manual. By
default, all fire dampers are supplied with a manual mechanism or actuator mechanism, optionally with a supply and
communication unit.
The activation mechanisms are removable and are interchangeable, for example an actuator operated mechanism
instead of a manually operated mechanism.
Highlights
• Lightweight construction
• Tightness class 3C as standard
• Low pressure drop
• Changeable mechanism
• Inspection opening built-in
• Great variety of installations rated up to EI120S
• Modulated actuator suitable for system balancing - possibility to open the blade at the desired angle.
Activation Types
Manually Operated Fire Dampers
By default, all manually operated fire dampers are supplied with manual control, optionally with micro switches and
electromagnets. In case of fire, the fire damper is closed automatically. Depending on the version, the damper closes
either after the melting of the thermal fuse or by means of remote activation through an electromagnet in impulse
connection. After the closing of the damper blade, it is mechanically locked in the closed position and can only be
opened manually. The actuating mechanism is activated when the temperature of the air in the duct reaches 74°C and
the damper closes within 10 seconds after the melting of the fuse.

Actuator Operated Fire Dampers
By default, all actuator operated fire dampers are supplied with an actuator with micro switches, optionally with a
power and communication unit. A fire damper can be equipped with a spring return actuator can be closed with
command from the building management system, or after the breaching of the thermoelectric fuse. Actuator operated
fire dampers are standardly equipped with a thermoelectric fuse, that activates the closing of the damper after the
reaching or exceeding of the ambient temperature of 72°C. The actuator power circuit is interrupted and its spring
closes the damper blade within 20 seconds.

Diagrams
The pressure drop and A-weighted total discharged sound power level depend on the nominal diameter of the damper
and air flow volume at different duct pressures. The type of activation does not influences the airflow parameter,
therefore only one activation type is shown in the diagrams.

Installation, Maintenance & Operation
Some damper parts may have sharp edges – therefore to protect yourself from harm, please use gloves during damper
installation and manipulation. In order to prevent electric shock, fire or any other damage which could result from
incorrect damper usage and operation, it is important to:
1. ensure that installation is performed by a trained person.
2. follow the written and depicted instructions provided within Handbook closely.
3. perform damper inspection in accordance with Handbook.
4. check the damper’s functionality as per the chapter “Fire Damper Functionality Check” before you install the fire
damper. This procedure prevents the installation of a damper that has been damaged during transportation or
handling.
Information about installation, maintenance and operation is available in the “Handbook_FDR-3G” document or more
can be found at design.systemair.com.
Installation rules
• The duct connected to the fire 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.
• According to the standard EN 1366-2, the distance between the fire damper bodies must be at least 200 mm. This
condition does not apply for tested distances. Therefore installations Wet and Soft are approved for smaller distances
under condition that the resulted resistivity is reduced to EI90S.
• The distance between the wall/ceiling and the fire damper must be at least 75 mm. This condition does not apply for
tested distances. Therefore installations Wet and Soft are approved for smaller distances under condition that the
resulted resistivity is reduced to EI90S.
• The fire damper must be installed into a fire partition structure in such a way that the damper blade in its closed
position is located inside this structure. A bendable hinge is provided on the damper body which represents a plane
where supporting constructure begins. This condition does not apply for installations On & Out.
• For each resistivity the minimum thickness of a its supporting construction cannot be decreased as per EN 1366-2 at
least 200 mm from the installation opening.
• The gap in the installation opening between the fire damper and the wall/ceiling can be increased by up to 50% of
the gap area, or decreased to the smallest amount possible that still provides sufficient space for the installation of
the filling.
IN ACCORDANCE WITH EN 15650, EACH FIRE DAMPER MUST BE INSTALLED ACCORDING TO THE INSTALLATION
INSTRUCTIONS PROVIDED BY THE MANUFACTURER!

18/67 | FDR-3G
Wet Installation
Using Plaster/Mortar/Concrete Filling
1.The supporting construction opening must be prepared as depicted. Opening surfaces must be even and cleaned off.
The flexible wall opening must be reinforced as per the standards for plasterboard walls. The opening dimensions are
driven by the nominal dimensions of the damper with added clearance. For circular dampers prepare the opening of
diameter D1.
2.Insert the closed damper into the middle of the opening so that the damper blade is in the wall. Use the bendable
hanger (2; or hangers) to secure the damper against the wall using a suitable screw (F1; recommended screwdiameter
5,5; e.g. DIN7981).
3.For damper diameter greater than 800 mm, it is recommended to use a duct support inside the damper to avoid
any damage, bend to the damper housing from the weight of the filling.
4.Fill in the area between the wall and the damper with plaster or mortar or concrete filling (2), while paying attention
to prevent the fouling of the damper’s functional parts, which could limit its correct functionality. The best way is to
cover the functional parts during installation. The seepage of the filling material can be prevented by using boards.
However, these are not required for wet installation.
First let the plaster or mortar or concrete filling harden and then perform the next steps!
5.After the filling hardens, remove the duct support from inside of the damper.
6.If needed, uncover and clean the damper after installation.
7.Check the damper’s functionality
Installation - Standard Distances
According to the standard EN 1366-2, the minimum distance from the wall or ceiling to the damper body is 75 mm.
For multiple crossings through a fire-resistive wall the minimum distance between two damper bodies is 200 mm. This
applies to distances between the damper and a nearby foreign object crossing the fire-resistive wall.
Installation - Smaller Distances - Maximum resistivity reduced to EI90S
The distance between 2 individual fire dampers can be reduced to 60 mm, measured from surface to surface of the
housing and the distance between the surface of the damper installed in the duct and the adjacent supporting
construction (wall/floor) can be reduced to 40 mm, provided that the fire resistance classification will be reduced as
follows: EI90 (ve i <-> o) S.
Installation in a Wall thinner than tested
Installation in a thinner wall is allowed under the condition that an additional layer/layers of fire protective board are
fixed to the surface of the wall in order to achieve the same length of damper penetration seal as was tested. The
minimum width of added boards around the damper is 200 mm. In addition, the alternative thinner wall should be
classified in accordance with EN 13501-2:2007 + A1: 2009 for fire-resistance required for product application. For a
protruding wall, the additional layers must be fixed on the steel supporting construction of the wall.
