The AH30-3-0 Communication Hub is the link between Aperio locks and the existing access control system. Up to 8 locks can be paired to one Hub and has a standard RS485 connection, making it compatible with most systems on the market today. It communicates directly with Aperio enabled locks via an encrypted 2.4GHz wireless link, and is designed to be positioned above the door within approximately 5 -25m of the lock.
