Product presentation CU2/B
The CU2/B damper is a battery assembly of several CU2 dampers with maximum 4 individual dampers (B12, B21 or B22) and with a
fire resistance up to 120 minutes. The CU2/B battery assembly is the ideal solution for installations with large dimensions.
Fire dampers are installed where air ducts penetrate fire-resistant compartment walls. Their role is to restore the fire resistance grade
of the penetrated wall and to prevent smoke propagation. Fire dampers are distinguished by their degree of fire resistance, by their
aeraulic properties as well as by their installation ease. Rf-Technologies’ fire dampers are all CE marked. They can be equipped with
various types of mechanisms depending on the specific needs linked to the project or to the local regulations.

10 Storage and handling
Storage and handling
As this product is a safety element, it should be stored and handled with care.
Avoid:
• any kind of impact or damage
• contact with water
• deformation of the casing
It is recommended:
• to unload in a dry area
• not to flip or roll the product to move it
• not to use the damper as a scaffold, working table, etc.
• not to store smaller dampers inside larger ones
Installation
General points
∎The installation must comply with the installation manual and the classification report.
∎Axis orientation: see the declaration of performance.
∎Avoid obstruction of adjoining ducts.
∎Product installation: always with closed damper blade.
∎Verify if the blade can move freely.
∎Please observe safety distances with respect to other construction elements. The operating mechanism must also remain
accessible: allow for a clearance of 200 mm around the housing.
∎The air tightness class will be maintained if the damper is installed according to the installation manual.
∎Rf-t fire dampers are always tested in standardised constructions according to EN 1366-2. The achieved results are valid for similar
supporting constructions with a fire resistance, thickness and density equal or superior to the supporting construction used
during the test.
∎The damper must remain accessible for inspection and maintenance.
∎Schedule at least 2 visual checks each year.

As the mechanism needs to be accessible at all times, you
need to provide a free working space of min. 200 mm. If the
mechanism is not accessible you need to provide an inspection

Maintenance
∎No specific maintenance required.
∎Schedule at least 2 visual checks each year.
∎Remove dust and all other particles before use.
∎Follow local maintenance regulations (i.e. BS9999 Annex V; NF S 61-933) and EN13306.
∎Read the maintenance instructions on our website: https://www.rft.be/assets//PIM/DOCUMENTS/BROCHURE%20KITS/BRO_K139_
MAINTENANCE_C.pdf
∎Use the damper at up to 95% humidity, non-condensing.
∎The fire damper can be cleaned with a dry or slightly damp cloth. It is forbidden to use abrasive cleaners or mechanical cleaning
techniques (brush).

Unlocking
∎manual unlocking: shortly press the unlocking button (1) once.
∎automatic unlocking: the fusible link reacts as soon as the temperature in the duct reaches 72°C.
∎remote unlocking: by interrupting the power supply.
Resetting
∎manual resetting: open the battery compartment (4) and press a 9V battery against the contact springs. Hold this position until
the LED (3) emits a continuous light. Check whether the indicator (2) shows that the damper blade is in the open position. Remove
the battery, the LED fades away. Close the battery compartment.
∎motorised resetting: switch off the power supply for at least 5 sec. Power the actuator (respect the prescribed voltage) for at least
75 sec. The resetting stops automatically when the end of range is reached (damper open).
Caution:
If the LED (3) flickers fast (3x/sec.), the battery is discharged: use a new battery.
If the LED (3) flickers slowly (1x/sec), the resetting is in progress.
If the LED (3) is continuously on, the resetting is complete and the motor is powered.
If the actuator detects voltage on the power cable, a brief contact of the battery is enough to start the resetting process.
The power supply of this actuator cannot be individually replaced. If the cable is damaged, the whole unit must be discarded
and replaced.
The housing of the mechanism contains a temperature sensor. When the temperature in the housing exceeds 72°C, the
mechanism unlocks. The LED flashes twice per second. When the temperature drops below 72°C, the mechanism can only be
reset in a motorised manner after a manual reset (with a battery).
The end of range switches need 1 second after operation to adopt a stable position.
Make sure the thermal trigger device is present in the actuator. The actuator might not function properly if this is not the case.

∎motorised resetting: via ZENiX controller. By applying voltage during first use (*).
Caution:
If the ONE-X detects voltage on the power cable, a brief contact of the battery is enough to start the resetting process,
provided the ZENiX controller has sent the damper to open position or the ONE-X is being operated for the first time.
The power supply of this actuator cannot be individually replaced. If the cable is damaged, the whole unit must be discarded
and replaced.
The housing of the mechanism contains a temperature sensor. When the temperature in the housing exceeds 72°C, the

The end of range switches need 1 second after operation to adopt a stable position.
Safety regulations:
Do not use the ONE-X for any application other than the specified applications, in particular not in aircraft or other airborne
vehicles.
The company that purchases and/or installs the ONE-X is fully responsible for the correct operation of the entire system.
Only authorised specialists may perform the installation. All rules and regulations, including statutory regulations, must be

∎automatic unlocking: the thermo-electric fuse reacts as soon as the temperature reaches 72°C (type BFLT).
∎remote unlocking: by interrupting the power supply.
Caution:
The thermo-electric fuse will not move the damper into its safety position (when the temperature reaches 72°C) if the motor
is not powered.
Resetting
∎manual resetting: turn the enclosed handle anti-clockwise. To block the motor, place the locking button on “lock”
∎motorised resetting: switch off the power supply for at least 10 seconds. Supply the actuator (respect the prescribed voltage) for
at least 75 seconds. The resetting stops automatically when the end of range is reached (damper open) - it takes about 60 seconds
to reset the damper - or when the power supply is interrupted.
Caution:
Do not use a drill or powered screwdriver.
Stop as soon as the motor is completely rearmed (end of range).

∎manual unlocking: place the locking button on “unlock”. (In case of BFNT: the damper can alternatively be unlocked by pushing
the “test” button on the thermo-electric fuse)
∎automatic unlocking: the thermo-electric fuse reacts as soon as the temperature reaches 72°C (type BFNT).
∎remote unlocking: by interrupting the power supply.
Caution:
The thermo-electric fuse will not move the damper into its safety position (when the temperature reaches 72°C) if the motor
is not powered.
Resetting
∎manual resetting: turn the enclosed handle anti-clockwise. To block the motor, place the locking button on “lock”
∎motorised resetting: switch off the power supply for at least 10 seconds. Supply the actuator (respect the prescribed voltage) for
at least 75 seconds. The resetting stops automatically when the end of range is reached (damper open) - it takes about 60 seconds
to reset the damper - or when the power supply is interrupted.
Caution:
Do not use a drill or powered screwdriver.
Stop as soon as the motor is completely rearmed (end of range).
Caution:
The mechanism may never be tested on its own, without being attached to the damper. Such a test might damage the
mechanism or the operator might be injured.
