3.Two readers, entry and exit access control

If additional security is needed at a particular door, or if the administrator needs a record of the time and date that people enter AND exit a door. Adding a second reader on the secure side of the door will require people to present a card to exit as well as enter. This scenario provides the added security benefit of allowing the system to control who can enter, and who can exit. It also allows the administrator to control when people can enter and exit.

Scenario 1 and 2 require one reader. Scenario 3 requires two. Each door module on the EverAccess controller can control two readers. Therefore, scenarios 1 and 2 allow one door module to control two doors. Scenario 3 requires one door module for each door. This is important to consider when choosing the appropriate number of modules and readers.

Determining System Structure as well as the Number of Controller and Modules

Determine how many controllers are needed, and whether an Ethernet interface is required.

1.Each EverAccess controller can accommodate up to 8 card readers. If the system to be installed requires more than 8 readers, additional controllers are necessary. These controllers can be connected to the system as described in chapter 4.

2.If one or more controller is to be installed at a different location than the system computer is to be installed, an Ethernet interface is required to connect over the internet. An Ethernet interface may also be used in locations at which the controllers are installed a long distance away from the system PC. Please refer to chapter 4 for more details on installing the Ethernet interface.
