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.
Available in series 2 ( from SW 50 ) up to 20 Nm included. For drives of series 2 adapters have to be ordered separately.
