The Wiegand and RS485 Lift Elevator Control Panel supports both RS485 and Wiegand interfaces. It can restrict access to up to 16 floors when combined with the BF-333 floor secure I/O. Each SEMAC S3 panel can connect with a BF-333. For instance, a lift with floor accession would be SEMAC S3 + BF-333 + RS485/Wiegand reader. The integration of our SOMAC software makes it easy to manage the entire elevator control system.
