Elevator Access Control systems allow people access to certain floors within a scheduled time frame. The system can control one or more elevator controllers in a system. It provides a range of system authority for users. The maximum number of elevators on the system depends on the control panel you choose. Elevator access can depend on the users classification, the time of day, which elevator is being approached, and the armed state of a department. In addition, changes to the status of a zone can either cause elevator to grant access to a floor, or cause the elevator to deny access.
