transfer fire dampers – mcr FID B/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 B/G
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
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.
