AxesMain is the main CPU board /gateway controller designed to manage the access control system. Access authorizations and rules are uploaded to the AxesMain resulting in autonomous functionality even when there is no connectivity to the axesplus® servers. To address different site architectures and ensure a flexible deployment, AxesMain can support Doors I/O boards (up to 4 AxesIO2 and 10 AxesI01) and Lifts I/O boards (up to 32 floors). In addition, the AxesMain can be used as a gateway bridging between the axesplus®servers and the AxesMain controllers. AxesMain can also be used as a Backup g ateway (Standby) unit to ensure system resilience and eliminate any single point of failure. The AxesMain can contain up to 65,000 cardholders details in its high capacity 32MB RAM.
