4. DESIGN AND OPERATING PRINCIPLE
Design
The mcr FID 240 single-blade fire dampers comprise a casing with a rectangular cross-section, a moving
isolation partition and a trigger control gear which is tripped remotely or automatically by tripping a thermal
trigger. The damper casing and moving isolation partition is made of fire-proof panel. The isolation partition
is 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 offire-proof
panel, which limit the rotating motion of the isolation partition. The damper has both ends of body with
flanged connections.
Function
The operating principle and behaviour of the mcr FID 240/... single-blade dampers depend on their
application versions:
cut-off fire dampers – mcr FID 240 /S
In the normal operating position the dampers are open. The dampers are closed (to the safety
position) as follows:
automatically, by tripping the thermoelectric trigger
manually, by pressing the control button on the thermoelectric trigger
remotely, by tripping an electric axial actuator with a return spring caused by isolation from the
supply voltage
automatically, by tripping the thermal trigger and the driving spring
cut-off fire dampers for fire ventilation systems – mcr FID 240 /V
In the normal operating position the dampers are closed. The dampers are opened (to the safety
position) as follows:
remotely, by tripping an electric axial actuator without a return spring, as a result of applying the
supply voltage to the actuator in the right manner
remotely, by tripping the electromagnetic release and a spring as a result of applying the voltage
cut-off fire dampers for mixed fire ventilation systems – mcr FID 240 /V-M
In normal operation the dampers are closed or open, depending on the function carried out. The
dampers are opened/closed (to the safety position) as follows:
remotely, by tripping the electrical axial actuator without a return spring in order to apply supply
voltage to the actuator in the right manner
remotely, by tripping the electromagnetic release and a spring as a result of applying the voltage
transfer fire dampers – mcr FID 240 /T
In the normal operating position the dampers are open or closed. The dampers are switched to the
safety position as follows:
automatically, by tripping the thermoelectric trigger
manually, by pressing the control button on the thermoelectric trigger
remotely, by tripping an electric axial actuator with a return spring caused by isolation from the
supply voltage
automatically, by tripping the thermal trigger and the driving spring
relief fire dampers – mcr FID 240 /G
In normal operation the dampers are closed or open, depending on the function carried out. The
dampers are opened/closed (to the safety position) as follows:
remotely, by tripping an electric axial actuator with a return spring caused by isolation from the
supply voltage The actuator has no thermoelectric trigger.
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.
The mcr T2 tester is recommended to check the proper performance of dampers with electric actuators.

6. DEVICE ASSEMBLY
CAUTION
During the assembly of the damper and installation finish, future access to the device and removal
of the triggering and control mechanism must be considered to enable servicing and inspection.
The mcr FID 240 dampers can be installed in the following building partitions (i.e. walls or ceilings):
masonry and concrete walls min. 150 mm thick
masonry walls of bricks or blocks min. 150 mm thick
panel walls min. min. 125 mm thick
floor slabs min. min. 150mm thick
Additionally, the dampers can be installed:
outside of walls
in modules (multiple damper sets)
The mcr FID 240 fire dampers may also be installed in partitions with a lower class of fire resistance. In
this case the damper fire resistance is equal to the partition fire resistance if the smoke tightness is met.
When installing the 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 recommended dimensions of the installation opening that permits correct installation of the rectangular
damper is (B+140)x(H+140) mm.

6.3. EMBEDDING / FIXING THE DAMPER
1. Damper mcr FID 240 BxH
2. Mounting anchors elements
Protecting the damper against buckling
The mcr FID 240 fire damper will work properly if the isolation partition rotation axis is horizontal. The
triggering and control mechanism 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 wool with non-
flammability class A1 confirmed by a certificate, and the density and thickness ensuring fire resistance not
lower than the resistance of the wall in which the damper is installed. Do not let the wool 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. Then mount the plasterboard bands around the damper body. The
moving isolation partition must remain closed throughout the installation. After installation, remove the
supports and reopen and close the damper to check if it works properly.
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 240 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.

7. TRANSPORT & STORAGE CONDITIONS
Fire dampers are packaged in cardboard boxes or placed on pallets. Dampers are protected against
damage by film or another covering material. Damper transport may take place using any means of
transport, provided they are protected against weather factors. Dampers placed on means of transport
should be secured against shifting of position during transport. Before installing dampers, control each of
them visually. Do not move the damper by holding by the connection cable or put a device on a release
and control mechanism. Do not hit or drop the damper. When moving and installing, support the damper
on the sides or edges of the body.
Dampers should be stored in closed rooms that provide protection against external weather conditions. In
the case dampers are stored on the ground, place them on protection pads in order to protect them against
damage. Storage should take place in rooms where:
• there is no access to dust, gases, caustic vapors and other aggressive chemical vapors that can
destroy insulating elements and structural elements;
• the dampers are not affected by direct sunlight and UV radiation;
• maximum relative humidity does not exceed 80% at the temperature of + 20 ºC;
• the ambient temperature is between - 20 ºC and + 40 ºC;
• there are no vibrations.
