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 W+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).

    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”
