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 S/T p/P
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 S/G p/P
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.
The operating principle and behaviour of the mcr FID S/... p/... single-plane dampers depend on their application
versions:
shut-off fire dampers
– mcr FID S/S p/O
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
shut-off fire dampers for fire ventilation systems
– mcr FID S/V p/O
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
shut-off fire dampers for mixed fire ventilation systems
– mcr FID S/M p/O
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 S/T p/O
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 S/G p/O
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.
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.
