Door Timezones are Highly Configurable and Essential to a Good System Design
Door Timezones are the backbone of any well designed access control system. They determine the when and how for personnel access through a door point. Though User Timezones are an integral part of the access process, they are associated with the Access Privilege Groups and work in conjunction with the Door Timezones.
The first thing to understand is that there are only two door states, Secure, which means the door is locked and requires a credential action to allow access, and Unsecure, which means the door is unlocked for free egress not requiring a credential action.
When a door is in a secure state (locked), there are 8 methods of credential presentation to gain access. The ninth method is the unlocked or public state.
The assumption is that the user or users presenting their credential has a valid access privilege group assignment for the door. In the below DID YOU KNOW? pdf, you will find a list of each method with a brief explanation.
