To disable a card, the user can designate a card as an invalid card. An invalid<br />

card cannot gain access to the system. At the same time, an Invalid Card event<br />

will be generated when an invalid card is presented to a reader.<br />

The controller generates alarm output(s) according to the settings in the<br />

“Invalid Card” column.<br />

• Invalid Door:<br />

Each card belongs to an access group. For each group, the system administrator<br />

can assign access privileges to certain doors for certain time zones. An Invalid<br />

Door event will be generated when a card is presented at any door at which it<br />

does not have the right to pass.<br />

The controller generates alarm output(s) according to the settings in the<br />

“Invalid Door” column.<br />

• Invalid Time:<br />

Each card belongs to an access group. For each group, the system administrator<br />

can assign access privileges to certain doors for certain time zones. An Invalid<br />

Time event will be generated when a card is presented at any door during a time<br />

period in which it does not have the right to pass.<br />

The controller generates alarm output(s) according to the settings in the<br />

“Invalid Time” column.<br />

• Card Anti-Passback Fail:<br />

Anti-Passback (APB) is an access control function whereby a cardholder is<br />

prevented from “passing back” his card to another person to gain entry into the<br />

same area twice, without leaving. Facilities are typically fitted with both Entry<br />

and Exit readers when Anti-Passback is implemented.<br />

A cardholder must alternate usage between entry and exit readers. If the<br />

cardholder attempts to pass through an entry reader twice consecutively, his<br />

access will be denied and the system will generate an illegal event when the<br />

cardholder’s card is configured as APB enabled.<br />

Be careful when enabling this function in a system if there are doors with single<br />

side readers. Cards with APB enabled will not allow the user to access doors<br />

unless they have both and entry and an exit reader.<br />

For a detailed description of Anti-Passback, please refer to the Anti-passback<br />

(APB) section in this chapter. A Card Anti-Passback Fail event will be generated<br />
