To disable a card, the user can designate a card as an invalid card. An invalid
card cannot gain access to the system. At the same time, an Invalid Card event
will be generated when an invalid card is presented to a reader.
The controller generates alarm output(s) according to the settings in the
“Invalid Card” column.
Invalid Door:
Each card belongs to an access group. For each group, the system administrator
can assign access privileges to certain doors for certain time zones. An Invalid
Door event will be generated when a card is presented at any door at which it
does not have the right to pass.
The controller generates alarm output(s) according to the settings in the
“Invalid Door” column.
Invalid Time:
Each card belongs to an access group. For each group, the system administrator
can assign access privileges to certain doors for certain time zones. An Invalid
Time event will be generated when a card is presented at any door during a time
period in which it does not have the right to pass.
The controller generates alarm output(s) according to the settings in the
“Invalid Time” column.
Card Anti-Passback Fail:
Anti-Passback (APB) is an access control function whereby a cardholder is
prevented from “passing back” his card to another person to gain entry into the
same area twice, without leaving. Facilities are typically fitted with both Entry
and Exit readers when Anti-Passback is implemented.
A cardholder must alternate usage between entry and exit readers. If the
cardholder attempts to pass through an entry reader twice consecutively, his
access will be denied and the system will generate an illegal event when the
cardholder’s card is configured as APB enabled.
Be careful when enabling this function in a system if there are doors with single
side readers. Cards with APB enabled will not allow the user to access doors
unless they have both and entry and an exit reader.
For a detailed description of Anti-Passback, please refer to the Anti-passback
(APB) section in this chapter. A Card Anti-Passback Fail event will be generated
