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).

  2. Blade position indicator
  3. LED red: status
  4. Battery compartment
  5. LED blue: communication
  6. LED orange: error message
  7. Supply
  8. Bus cable
  9. Bus cable

Variants

  • ONE-X 24
    Spring return actuator ONE-X 24V (with fusible link T) with integrated communication module
  • ONE-X 230
    Spring return actuator ONE-X 230V (with fusible link T) with integrated communication module

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
    via ZENiX controller

Resetting

  • manual resetting
    Open the battery compartment (4) and press a 9V battery against the contact springs. Hold this position until the red LED (3) emits a continuous light. Control whether the indicator (2) indicates that the damper blade is open. Remove the battery. Close the battery compartment.

BFL(T) - Remotely controlled spring return actuator

The spring return actuator BFL(T) is especially designed to operate fire dampers remotely. The BFL(T) variant is intended for fire dampers with smaller dimensions (CR60, CR120, CR2 with ø ≤ 400 mm, CRS60 with ø ≤ 315 mm, CU2 / CU2-15 / CU4 with B+H ≤ 1200 mm or for CU-LT and CU-LT-1s). For Markage FD with H = 200 mm or H = 2200 mm (in combination with BFT motor).
  1. Locking button
  2. Plug (ST)
  3. Access for manual resetting
  4. Thermo-electric tripping device (T)

Variants

  • BFL24
    Spring return actuator BFL 24V
  • BFL24-ST
    Spring return actuator BFL 24V with plug (ST)
  • BFL230
    Spring return actuator BFL 230V
  • BFLT24
    Spring return actuator BFL 24 V with thermo-electric fuse (T)
  • BFLT24-ST
    Spring return actuator BFL 24 V with thermo-electric fuse (T) and plug (ST)
  • BFLT230
    Spring return actuator BFL 230 V with thermo-electric fuse (T)

Options - Switch

  • SN2 BFL/BFN
    Auxiliary limit switch 'open/closed'

Unlocking

  • manual unlocking
    place the locking button on “unlock”. (In case of BFLT: 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 BFLT).
  • remote unlocking
    by interrupting the power supply.

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.
