Figure 3 Possible Reader Locations for Local Anti-Passback

Note

Request to Exit switches should not be used when anti-passback is required because they infringe

passback security every time they are used.

There are two types of local anti-passback available:

1. Anti-Passback on Entry. When this feature is active, any key used to enter an area cannot be used

to enter the area again unless it has first been used to leave the area. Using the example shown in

Figure 3, if you use your key to enter development, you cannot use the same key to enter

development unless it has first been used to leave development. If the key is used again at an entry

door, a No Entry: Passback transaction is generated and the lock will not operate. Access will

continue to be denied until the key has been used at an exit reader or the passback timeout period

has expired.

2. Anti-Passback on Exit. When this feature is active, a key cannot be used to exit an area unless it

has first been used to enter the area. This is only available when anti-passback on entry is also

active. Using the example shown in Figure 3, if you have not used your key to enter development

(e.g. you came in with someone else), you cannot use your key to leave development. If the key is

used again at an exit door, a No Exit: Passback transaction is produced and the lock will not

operate. Access will continue to be denied until the key has been used at an entry reader or the

passback timeout period has expired.

Note

If door monitoring is used, local anti-passback will only be set if a key is presented and the door is

opened. Simply presenting a key will not set local anti-passback. If door monitoring is not used,

local anti-passback will be set when a valid key is presented.

1.3.13.2 Timed Anti-Passback

Timed anti-passback is where the period for which a key is denied access is specified. After the specified

period has elapsed the key will be allowed access again, even if it has not been used to leave the area.

The time may be set to between 10 and 70 minutes in 5 minute steps (10, 15, 20, etc.).

Using the timeout period means you could use anti-passback without an exit reader. A car park, for

instance, may have an entry barrier with a reader. When a key is used to raise the barrier, that key will not

be able to gain access again until the time period expires. Provided that genuine use of the key is unlikely

to be needed within the time period, no exit reader is required.

Note

Timed anti-passback also works with global anti-passback.
