place where the insulation is performed, there is a swelling gasket. The sealing at the partition circumference is
effected by a rubber gasket installed on the partition.
The enclosure is ended from both ends with flange connections.
Action
The principle of action and behaviour of single-plane dampers mcr FID S/… c/P depends on the version of their
application:
shut-off fire dampers – mcr FID S/S c/P
In normal operating position, the dampers are open. Closing the dampers (safety position) takes place:
automatically, by activation of the thermoelectric release
manually, by pressing the control button at the thermoelectric release
remotely, by activation of an electric axial actuator with a return spring, as a result of removing
its supply voltage
automatically, by activation of the thermal release and the actuation spring
shut-off fire dampers for fire ventilation systems – mcr FID S/V c/P
In normal operating position, the dampers are closed. Opening the dampers (safety position) takes place:
remotely, by activation of 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 activation of the electromagnetic release and a spring as a result of applying the voltage
shut-off fire dampers for mixed fire ventilation systems – mcr FID S/V-M c/P
In normal operation dampers are closed or open, depending on the function carried out. Opening/closing the
dampers (safety position) takes place:
remotely, by activation of the electrical axial actuator without a return spring in order to apply supply
voltage to the actuator in the right manner
transfer fire dampers – mcr FID S/T c/P
In normal operating position, the dampers are open. Closing the dampers (safety position) takes place:
automatically, by activation of the thermoelectric release
manually, by pressing the control button at the thermoelectric release
remotely, by activation of an electric axial actuator with a return spring, as a result of removing
its supply voltage
automatically, by activation of the thermal release and the actuation spring
relief fire dampers – mcr FID S/G c/P
In normal operating position, the dampers are open. Closing the dampers (safety position) takes place:
remotely, by activation of an electric axial actuator with a return spring, as a result of removing
its supply voltage The actuator has no thermoelectric release.
It is possible to check the correctness of damper co-operation with an electrical actuator manually, for service
purposes using a special hex wrench placed in the socket marked on the actuator, and rotated to set the damper
partition in the relevant position. Wrench rotation should be done evenly, slowly and carefully. Too quick or too rapid
rotation of the key may cause damage of the internal actuator mechanism, or damage of the drive transmission
system.
In the integrated version it is possible to check the correctness of damper co-operation with a release and control
manually, for service purposes by pressing a lever on the mechanism.
NOTE
In any case it is forbidden to pull directly by the damper partition in order to open or close
it. Such an action may cause damage of the devices' self-braking drive mechanism and is
not covered by the warranty.
It is recommended that the fire damper were opened and closed when the ventilation
system is turned off.
