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.

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).

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.
