4. DESIGN AND OPERATING PRINCIPLE
Design
The mcr FID S/… p/… single-plane fire dampers comprise a casing with a rectangular or circular cross-section
(depending on the form version), a moving isolation partition, made of two segments separated by a fire-proof panel,
and a trigger control gear which is tripped remotely or automatically by tripping a thermal trigger. The damper casing
is made of steel sheet, galvanized steel sheet or stainless steel sheet. The isolation partition is made of a fire-proof
panel set in a reinforcement profile made of metal sheet. The inner side of the fire damper casing features a
intumescent gasket. There are stop shapes fastened to the inner casing surface and made of steel, galvanized steel
or stainless steel sheet, which limit the rotating motion of the isolation partition. The stop shapes are lined with a
ventilation-grade seal. The rectangular form version has both ends of the fire damper body with flanged connections,
whereas the circular form version features nipple connections (øD-2). The circular form version can also be
manufactured with flanged ends.
Function
The operating principle and behaviour of the mcr FID S/... p/... single-plane dampers depend on their application

It is possible to manually service check the proper performance of the dampers with electrical actuators by placing a
special hex wrench in the socket marked on the actuator and rotating it to set the damper isolating partition in the
relevant position. Rotate the wrench slowly, smoothly and carefully. Rotating the wrench too fast or too rapidly may
damage the internal actuator gear or the drive transmission system.
It is possible to manually service check the proper performance of the integrated damper with the trigger control gear
by pressing the lever on the gear.
The mcr T2 tester is recommended to check the proper performance of dampers with electric actuators.
CAUTION

Never pull directly on the damper isolation partition to open or close the device. This may result in
damage of the self-locking driving gear of the damper that is not covered by warranty. It is
recommended that the fire damper were opened and closed when the ventilation system is turned
off.

fire damper in a wall the thickness of which is below the required minimum, increase the thickness at the installation
location e.g. by adding an extra slab or other suitable construction material around the damper circumference.
6.1. PRE-ASSEMBLY INSPECTION
Each fire damper is factory inspected by the manufacturer prior to packing and shipping. Upon unpacking the
delivered fire damper, visually examine it for any damage in transport or casing deformation.
6.2. INSTALLATION OPENING
The minimum dimensions of the installation opening that permits correct installation of the rectangular
damper is (B+90)x(H+90) mm. The minimum dimensionsof the installationopeningfor thecircular damper
is (D+90) mm.
Preparation of the installation opening
6.3. EMBEDDING / FIXING THE DAMPER
Protecting the damper against buckling
The mcr FID S/... p/.. fire damper will work properly if the isolation partition rotation axis is horizontal. If the fire damper
must have the axis in the vertical, state this when ordering. In this case the manufacturer adds optional accessories
with keep clearance between the damper body and the partition at the damper bottom. If the fire damper must be
installed with the rotation axis vertical when the device has already been delivered on site, follow Section 6.5.
The trigger control gear may be located on the right or on the left hand side of the damper at any direction of air flow.
Before embedding/fixing, place the damper axially aligned within the partition (the wall or ceiling which separates the
fire zones) in the finished installation opening. Level the device and secure in place. Next, actuate the damper
isolation partition by hand to verify that the rotation is correct (i.e. there is no collision with the damper casing parts,
etc.). Close the damper isolation partition. Install the bracing as shown in the figure. Carefully fill the gap between
the damper casing and the wall with a proper mortar formula that ensures proper wall and damper fire resistance,
and do not let the mortar get into the damper actuation components (i.e. the trigger control gear, the isolation partition,
gaskets and stops). To do this, the fire damper must be covered with plastic film or other suitable material and remain
so until the embedding and finishing is done. The damper must remain closed until the mortar has cured. Once the
mortar has cured, remove the temporary supports and open and close the fire damper to verify its performance.
When installing the fire damper in a panel wall, fill the space between the damper casing and the wall with mineral
wool certified for A1 fire protection rating; the mineral wool density and thickness must ensure fire resistance no less
than the fire resistance of the wall in which the fire damper is installed. The filled space must additionally be sealed
with a proper mortar or putty that has the fire resistance required for the wall.

In order to ensure the fire resistance of the fire separation element, it is mandatory to keep the embedding envelope
boundary: the damper isolation partition rotation axis must be within the wall envelope.
The embedded fire damper must be coaxially connected to the ventilation duct. Protect the fire damper casing from
damage, and specifically from straining the casing during the installation process. The fire damper cannot bear the
load of the ventilation duct or the ventilation system in which it is installed. Drilling the damper enclosure or driving
screws, bolts or other elements that pierce through the casing to the inside of the damper is prohibited. Once
connected to the ventilation ducts, re-verify the fire damper performance.
During the installation of the mcr FID S/... p/... fire damper mind specifically that the thermal trigger (a fusible element)
must not be damaged or exposed to high temperature (from fire, and welding/soldering equipment), which might
trigger it (it is a single use element and not subject to warranty replacement). Do not expose the intumescent gaskets
installed in the fire damper casing to high temperature. Swollen gaskets make it impossible to close the damper. With
the installation finished, carefully clean the fire damper and make sure that there is no debris which could influence
proper performance of the device.
CAUTION
It is crucial to keep the device embedding envelope so that the trigger control gear is outside of
the wall envelope and easily accessible.

CAUTION
* Smoke extraction duct should be made in accordance with the duct manufacturer's guidelines. The ducts must have
adequate fire resistance in accordance with the fire resistance provided for the entire solution. Seal all connections
between the damper and the ducts with appropriate mortar / glue / gaskets, ensuring fire resistance. The shut-off
damper in vertical position fire ventilation systems may be mounted across the horizontal smoke extract duct or on
the sides of the horizontal smoke extract duct or on the surface of any side of the vertical smoke extract duct.
