Working as a standalone solution, GV-AS120 is a card reader and also a single door controller. It is possible to add one more card reader to GV-AS120 for entry and exit applications. GV-AS120 has the capability to store up to one thousand cards. When GV-AS120 is being used as a standalone unit, the programming is done from the software GV-ASManager through the RS-485 connection.
An economic solution for access control, GV-AS120 is suitable for controlling doors, parking gates and access to elevator call buttons.
