2.3.14 Multiple Reader Formats

Readers with a 26-bit Wiegand output can be

connected directly to the door controller (see Figure

27 and Figure 28 for details).

Note:

If these readers are used, you can only connect one

reader per channel. If you require an in and out

reader, you must use lock sharing where two reader

channels are used to control the same lock.

2.3.15 Anti-Passback

Local Anti-Passback

Local anti-passback records which keys have been

used to enter an area. This information is then used

to determine whether or not a key can be used to

enter or leave the area. This can be used to prevent

keyholders passing their keys to others to gain entry.

Local anti-passback only operates between the doors

on a single door controller with specific readers

allocated as entry (“Doors” 1 and 2) and exit

(“Doors” 3 and 4) - see Figure 4.

Note:

On the Readykey K1200, which only controls 2 doors,

Door 1 is entry and Door 2 is exit.

Figure 5: Possible Reader Locations for Local Anti-Passback

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 5, 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 produced and the lock will not

operate. Access will continue to be denied until

the key has been used at an exit reader.

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 5, 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.

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.
