  4. Battery compartment to reset motor
  5. Plug (ST)

Variants

  • ONE T 24 FDCU
    Spring return actuator ONE 24V (with fusible link) + unipolar beginning- and end-of-range switch
  • ONE T 24 FDCB
    Spring return actuator ONE 24V (with fusible link) + bipolar beginning- and end-of-range switch
  • ONE T 230 FDCU
    Spring return actuator ONE 230V (with fusible link) + unipolar beginning- and end-of-range switch
  • ONE T 230 FDCB
    Spring return actuator ONE 230V (with fusible link) + bipolar beginning- and end-of-range switch
  • ONE T 24 FDCU ST
    Spring return actuator ONE 24V (with fusible link) + unipolar beginning- and end-of-range switch and plug (ST)

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).

BFL(T) - Remotely controlled spring return actuator

The spring return actuator BFL(T) is specially designed to remotely control fire dampers. The BFL(T) model is intended for fire dampers with smaller dimensions (ø ≤ 400 mm or W+H ≤ 1200 mm/1400 mm for CU-LT, CU-LT-1s).
  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)
  • BFLT24
    Spring return actuator BFL 24V with thermo-electric fuse (T)
  • BFLT24-ST

  • BFL230
    Spring return actuator BFL 230V
  • BFLT230
    Spring return actuator BFL 230V 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.
