SEE-NHK
Roller shutter drive with crank-operated emergency operation
Product information
The emergency and escape route drive for added safety.
The drive SEE-NHK for roller shutters combines easy setting of end limit positions and maximum operating safety. Next to the thought out characteristics of the SEE drive (maximum construction protection and the tight closing of the construction) an operation with emergency hand crank is possible – e.g. in case of an emergency and power failure. After the SEE NHK has been cranked upwards manually, the drive programms the end limit positions automatically.
SEE NHK drives have to be installed with blocking springs or burglar proof fixations and need a fixed end limit on top. The parallel connection of various SEE NHK drives is possible.
The one-way clutch installed between the crank and the rocker bearing ensures that the blind can only be cranked in the correct direction, i.e. upwards. This prevents the system from being damaged. When cranking the shutter in the wrong direction of rotation, the force is not transferred by the one-way clutch.
Available in series 2 ( from SW 50 ) up to 20 Nm included. For drives of series 2 adapters have to be ordered separately.
PRODUCT BENEFITS
- 13:1 gear transmission lets you crank open the roller shutter quickly in an emergency
- Emergency hand crank delivers excellent reliability, ensuring that the emergency function works even in the event of a power failure
- Operating the emergency hand crank does not shift the end positions of the roller shutter
- Requires absolutely no maintenance
- Plug-in connection cable (universal connector)
- Quick and easy plug & play end position setting
- Obstacle detection in downward direction and learning overload protection in upward direction (protection against freezing) extend roller shutter service life
