Based on the record system 20, the record STA 21au has been modified to meet the requirements of light to medium doors in heavy duty applications. Both have the same Swiss engineered intelligence system, enabling the interactive exchange of
information between control, sensors and electronic remote control unit. The majority of the record STA 21au components are taken from the famous record system 20, which has a proven track record in global markets, but fitted with smaller, lighter electrical motors and a specially modified control.
