3.4.5 Anti-Passback Feature

The anti-passback feature prevents users from giving access to others by “passing back” their

access cards. In a typical anti-passback installation, users must “register” themselves by

accessing a door programmed as Entry when they enter the building. They will only be

allowed to leave from a door programmed as Exit. A user cannot access an Entry door twice

consecutively. The menu allows users to be “forgiven” (allowed access even if

they have not exited properly) and provides other anti-passback options. See Section 3.4.6.

Figure 3-8 below shows an example of anti-passback application. In this example, employees

enter through an anti-passback doors (must enter and exit through separate doors). The man-

ager’s entrance is not an anti-passback door, allowing employees to come and go freely.

Note: The anti-passback feature must be enabled through programming. See Section 6.
