Unlocking
∎
manual unlocking: place the locking button on "unlock". (For types 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.
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 screwing machine.
†
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 fire damper. Such a test
might damage the mechanism or the operator might be injured.
