Hand crank fixed in case of power failure for ERN/ERFN motors, white 1000 mm ( 1 ST ) fest | 1000 mm

If rescue windows or escape doors are closed by electrically operated roller shutters, it must be ensured that even if the electric drive fails, the roller shutter can be raised manually and the escape window or escape door can therefore be opened from the inside.

Appropriate technical solutions for windows and doors must meet the requirements of fire protection officers and approving authorities and can vary depending on the federal state.

The additional hand crank (emergency hand crank) for emergency operation offers a mechanical alternative to opening an electrically operated roller shutter. Installation is carried out on the roller shutter box either on the wall or visually concealed within the reveal. The latter depends on the respective component and the installation situation and cannot always be implemented.

The crank is not removable, but is firmly connected to the roller shutter motor and is fixed to the masonry using a small plastic holder.
