Description
Fire dampers with round Kit up to size 630 mm represent passive fire protection, designed with the help of
compartmentalization to prevent the spread of toxic gases, smoke and fire. FDR-3G...KR fire dampers installation is
designed with simplicity in mind. Standard fire dampers are designed and certified in accordance with EN 15650 and
tested for EIS criteria according to EN 1366–2. By default, all fire dampers are supplied with an manual mechanism or
actuator mechanism, optionally with a supply and communication unit.
IMPORTANT: The installation kit can not be delivered separately! The installation kit is delivered pre-mounted on a
damper.
Highlights
•Fast installation rated EI60S, EI90S, EI120S
•Tightness class 3C as standard
•Low pressure drop
•Changeable mechanism
•Inspection opening built-in
•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.
• H0-KR
Fire damper with an activation mechanism with a cover, manual crank and with a spring return release mechanism
activated by a fusible thermal link set to 74°C (on demand 100°C).
• H2-KR
Fire damper with an activation mechanism H0 + open and closed indication with AC 230 V or AC/DC 24 V contact
switches.
• H5-2-KR
Fire damper with an activation mechanism H0 + a AC/DC 24 V electromagnetic release mechanism in the impulse
connection (release takes place when the electromagnet is activated) + open and closed indication with AC 230 V or
AC/DC 24 V contact switches.
• H6-2-KR

4/35 | FDR-3G...KR
Fire damper with an activation mechanism H0 + an AC 230 V electromagnetic release mechanism in the impulse
connection (release takes place when the electromagnet is activated) + open and closed indication with AC 230 V or
AC/DC 24 V contact switches.
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.
The activation mechanisms are removable and are interchangeable, for example an actuator operated mechanism
instead of a manually operated mechanism.

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 SystemairDESIGN.
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.
• The distance between the fire damper bodies is defined by the Kit base plate. Smallest distance between two
dampers with kit is when the Kit base plates are touching.
• The distance between the wall/ceiling is defined by the Kit base plate. Smallest distance between wall/ceiling and a
damper with kit is when the Kit base plates is touching wall/ceiling.
• 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. Kit base plate on the damper body represents a plane where supporting
constructure begins.
• 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.
IN ACCORDANCE WITH EN 15650, EACH FIRE DAMPER MUST BE INSTALLED ACCORDING TO THE INSTALLATION
INSTRUCTIONS PROVIDED BY THE MANUFACTURER!

15/35 | FDR-3G...KR
Installation - Kit
Installation Using an Installation Kit
IMPORTANT: The installation kit can not be delivered separately!The installation kit is delivered pre-mounted on a
damper.
1. The supporting construction opening must be prepared as depicted. Opening surfaces must be even and cleaned
off.
2. 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.
3. This is the simplest installation method. Insert the damper into the opening and fix the front panel using
appropriate screws (recommended screw diameter 5,5 - e.g. DIN7981) into pre-drilled holes.
4. If needed, uncover and clean the damper after installation.
5. Check the damper’s functionality
Installation - Standard Distances
The distances are defined by the kit base plate. Minimum distances are when kit base plate is touching ceiling or side
wall. This means from the wall or ceiling to the duct axis it is Wp/2. For multiple crossings through a fire resistive wall
the minimum distance between two duct axes is Wp, this means the Kit base plates are touching. This Kit base plate
also serves as a distance limiter for nearby foreign objects crossing the fire resistive wall.
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.
