The fire ratings depend on the use as well as the manner and place of fire damper installation.
Manufacturing versions
The mcr FID PRO type fire dampers may be manufactured as:
rectangular fire dampers
rectangular fire dampers with circular connections
round fire dampers
Size range
The mcr FID PRO type fire dampers are manufactured in the following dimensions:
width: from 100 to 315 mm
width for nipple fire dampers: 170 mm (with an option to be extended to 310 mm)
width for coupling fire dampers: 140 mm (with an option to be extended to 280 mm)
The fire dampers may be additionally fitted with connection flanges.
Apart from the standard dimensions, there is a possibility to manufacture fire dampers with any dimensions within
the above ranges. The maximum surface area of the mcr FID PRO type fire damper is 0.078 m2. The minimum
surface area of these fire dampers is 0.008 m2.
4. DESIGN AND OPERATING PRINCIPLE OF THE FIRE DAMPER
Design
The mcr FID PRO single-plane fire dampers consist of a housing with a round cross section, movable cut-off partition
as well as a release and control mechanism which is started remotely or automatically (after a thermal release has
been actuated). Fire dampers’ housings are made of galvanised steel sheet or stainless steel sheet. In the fire
damper’ housing, along its perimeter, there is an insulation perforation of suitable width. The fire damper’s cut-off
partition is made of non-flammable board. The partition is lined on both sides with sheet metal reinforcement. On the

housing, in the area of insulation perforation, an intumescent seal is installed. Along its perimeter, the partition is
sealed by means of a rubber seal installed on the partition.
Normally, the fire dampers have a spigot (nipple or coupling) connection. Connection flanges are available on request.
Operation
The operating principle and behaviour of the mcr FID PRO single-plane fire dampers depends on the version and
use:
mcr FID PRO/S fire dampers
These dampers remain open during normal operation. They are closed (safety position) in the following ways:
automatically – by actuation of the thermoelectric release
manually – by pressing the control button on the thermoelectric release
remotely – by actuation of the axial electric actuator with a return spring as the supply voltage disappears
automatically – by actuation of the thermal release and the power spring
mcr FID PRO/V fire dampers for fire ventilation systems
These fire dampers remain closed during normal operation. They are opened (safety position) in the following
ways:
remotely – by actuation of the axial electric actuator without a return spring as the
supply voltage is appropriately applied to the actuator
remotely – by actuation of the electromagnetic release and spring as the voltage is supplied
mcr FID PRO/M fire dampers for mixed-mode fire ventilation systems
Depending on the function they serve, these fire dampers remain either closed or open during normal operation.
They are opened/closed (safety position) in the following ways:
remotely – by actuation of the axial electric actuator without a return spring as the supply voltage is
appropriately applied to the actuator
mcr FID PRO/T transfer dampers
These dampers remain open during normal operation. They are closed (safety position) in the following ways:
automatically – by actuation of the thermoelectric release
manually – by pressing the control button on the thermoelectric release
remotely – by actuation of the axial electric actuator with a return spring as the
supply voltage disappears
automatically – by actuation of the thermal release and the power spring
mcr FID PRO/G pressure relief fire dampers
These dampers remain open during normal operation. They are closed (safety position) in the following ways:
remotely – by actuation of the axial electric actuator with a return spring as the
supply voltage disappears The actuator does not have a thermoelectric release.
It is possible to check manually the correct functioning of a fire damper with electric actuator for maintenance
purposes. To do this, use a special hex key which should be placed in the socket marked on the actuator. Then, by
rotating the hex key, the fire damper’s partition may be set in the desired position. Bearing in mind to take enough
care, rotate the hex key uniformly and slowly. Too fast and violent rotation may cause damage to the internal
mechanism of the actuator or the power transmission system.
To manually check correct operation of fire dampers with a manual release and control mechanism in the integrated
version for maintenance purposes, press the lever on the mechanism.
NOTE
Never try to open or close a fire damper’s partition by pulling it directly. Such attempts may cause
damage to the self-locking powertrain of a fire damper and this is not covered by warranty.
It is recommended that the fire damper were opened and closed when the ventilation system is
turned off.

6. INSTALLATION OF THE FIRE DAMPER
NOTE
During the installation of a fire damper and while conducting finishing work, you should allow for
the possibility of later access to the fire damper and removal of the release and control mechanism
in order to carry out possible service work and technical inspections.
The mcr FID PRO fire dampers may be installed in the following space dividing elements (walls or structural floors):
masonry/concrete walls with the minimum thickness of 120 mm
brickwork walls or blockwork walls with the minimum thickness of 125 mm
walls made of boards with the minimum thickness of 125 mm
structural floors with the minimum thickness of 150 mm

mcr FID PRO single-plane fire dampers
„MERCOR” SA – the Company reserves the right to make modifications and changes. 9/24
Additionally, fire dampers may be installed:
outside walls
in dampers sets (multiple damper sets)
How to fill the space between the damper and the partition:
wet - e.g. cement, gypsum or other mortar with appropriate approvals for use in construction, ensuring the required
fire resistance of the set: partition / filling / flap
dry - installation culvert system based on mineral wool and sealing / swelling mortars.
The mcr FID PRO fire dampers may also be installed in space dividing elements in buildings that have a lower fire-
resistance rating. In such cases, fire dampers will have a fire-resistance rating equal to that of a space dividing
element, with the condition of smoke leakage rating being satisfied. When installing a fire damper in a given type of
wall which is thinner than required, its thickness should be increased along the perimeter of the fire damper, e.g. by
installing an additional board or other building element.
6.1. PRE-INSTALLATION INSPECTION
Each fire damper is inspected by the manufacturer before packing and transport. Once the product has been
unpacked at the destination, visual inspection should be conducted to check for possible deformations of the housing
or fire damper transport damage.
6.2. INSTALLATION OPENING
The minimum size of the opening enabling correct installation of the damper is:
• for dampers installed in the wet system, filling the gap between the partition and the damper: min. (D + 40) mm. In
the case of flange mounted dampers, the mounting hole is a minimum (D + 80) mm. For light walls minimum □ A (D
+ 40).
• for dampers installed in a dry system, filling the gap between the wall and the damper: min. (D + 100) mm. In the
case of flange mounted dampers, the mounting hole is a minimum (D + 140) mm. For light walls □ A (D + 100).

6.3. BUILDING IN (EMBEDDING) THE FIRE DAMPER
NOTE

mcr FID PRO single-plane fire dampers
„MERCOR” SA – the Company reserves the right to make modifications and changes. 10/24
At least a 2.5 mm gap between the body and partition has to be ensured at each place along the fire damper
perimeter. The fulfilment of this requirement is a prerequisite for product warranty.
Ensuring an appropriate gap between the fire damper body and partition
The mcr FID PRO fire damper works correctly if the rotation axis of the partition is horizontal. The release and control
mechanism may be located on the right or left of a fire damper irrespectively of the air flow direction. Installing a fire
damper on its side, i.e. with rotation axes of the partition being vertical, is only permitted when this has been
previously made known to the manufacturer at the time of placing the order.
Before building in/embedding, a fire damper should be placed axially in a space dividing element (a wall or structural
floor that divides separate fire compartments), i.e. in a previously prepared opening. Next, level and secure the fire
damper so that it does not move. Once the above have been completed, start manually the fire damper’s partition,
checking if it rotates correctly (it should not touch the housing elements, etc.). Close the fire damper’s partition. The
gap between the fire damper’s housing and the wall should be completely filled with appropriate mixture which will
provide the required fire-resistance rating of the wall and the fire damper. Moreover, special attention should be paid
to ensure that the mixture does not come into contact with the equipment of the fire damper responsible for its proper
operation (release and control mechanism, partition, seals and limiters). For this purpose, it is essential that you put
plastic film or other material on the fire damper, which will protect it while masonry and finishing work is being carried
out. The partition has to remain closed until the mixture sets. Once it has set, remove the brackets. Then, again open
and close the fire damper in order to check if it works correctly. In the case of installation of a fire damper in a wall
made of boards, the space between the fire damper’s housing and the wall should be completely filled with A1 class
non-flammable (certified) mineral wool. Its density and thickness should ensure fire-resistance not lower than that of
the wall in which the fire damper has been installed. Additionally, the filled space should be sealed with an appropriate
mixture or mastic having fire-resistance required by the wall.
In order to ensure fire-resistance of a fire separation, the depth to which it can be built in should never be exceeded,
i.e. the rotation axis of the fire damper’s partition cannot be outside the wall (off the wall surface). In the case of space
dividing elements with a thickness comparable to that of a fire damper, it is recommended that the fire damper be
installed in such a manner that its axis divides the thickness of the space dividing element precisely in half.
The installation of the fire damper off the wall shall be the exception to the above rule. If the fire damper is installed
this way, a ventilation duct section between the fire damper’s partition and fire separation shall be secured by means
of fire-resistant boards or layers of mineral wool and structurally reinforced as recommended by the manufacturer of
the solution. The fire resistance of the duct between the fire damper and the fire separation construction, should have
a classification of not less than required for the fire damper and fire separation. The fire damper can be installed at a
maximum distance of 1000mm from the fire zone space dividing elements.
The built-in fire damper has to be coaxially connected to a ventilation duct. When installing a fire damper, be sure
that you do not damage its body, and in particular do not subject it to any stress. A fire damper cannot function as a
“structural element” of a duct or ventilation system in which it has been installed. It is unacceptable to drill through
the fire damper’s housing, screw in bolts/screws and other elements that pierce through the housing towards the
interior of the fire damper. Having connected the fire damper to a ventilation duct, check again if it works correctly.
When installing the mcr FID PRO fire dampers, ensure in particular that the thermal release (fusible component) is
not damaged. It should not be exposed to high temperature (fire, welders, soldering irons) which causes its actuation
(it is a component that has been designed to be used once only and will not be replaced under warranty). Similarly,
the intumescent seals installed in the housing of the fire damper should not be exposed to high temperature.
Expansion of the seals makes it impossible to close the fire damper. After the installation has been completed, clean
thoroughly the fire damper and ensure that no debris has been left inside, as it could affect its correct operation.

Note:
Controlling the operation of BE and BLE actuators requires connecting them to an electrical wiring system using
three-wire cables. The change of rotation direction is effected by applying supply voltage to terminal 2 or 3, depending
on the desired direction of rotation.
The position of limit switches for all actuator types applies to a potential free position.
For proper operation of a device equipped with electrical actuators, it is recommended that the rated voltage housed
tolerance of 24V±10% or 230V±10%. Power supply devices other than listed above may cause malfunction and will
not be covered by the warranty conditions.

RST/KW1 release and control mechanism
In the RST/KW1/S manufacturing version, the limit switches are installed on the mechanism itself. Electrical
connection is carried out by connecting the wires (marked accordingly) to the electrical wiring system. The fusible
release link is installed on the mechanism itself. The dampers with the RST/KW1/230I, RST/KW1/230P mechanisms,
are supplied with the RST/KW1/24... triggering and control mechanism, together with the 230/24V transformer
module type MP230/24. For the trigger and control mechanism of the "impulse" type damper, adequate power must
be provided to ensure that the control signal is supplied to the device in the event of fire.
