Adding a request to exit device to scenario 1 allows the system to control when to

allow people to exit through a door. Request to exit devices include buttons that a

person must press in order to exit, or a motion detector that automatically unlocks

the door when a person approaches. These devices are always installed on the

secure side of the door.

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.

Determine Fingerprint Access Requests

The biometric recognition technology used in the fingerprint controller provides a higher

security level than regular card access system. Determine the number of the access points where

the fingerprint access is required. The fingerprint controller has a built-in reader, so it can be

used as an entry reader. A common door configuration with the fingerprint controller is shown

in the below figure:
