Allow operator defined linkage triggers to use the same logic as in AutoUnlock trig-
gers (i.e., prevent a trigger from occurring while in a Global Lock/Unlock state).

These applications are made possible by including the Global Lock and Global Unlock
Trigger variables (used by the MSC based controller to indicate its current “Global” state)
as selections in the local linkage trigger menu.

NOTE: These two trigger variables are not displayed in the local linkage procedure
menus as the system cannot allow the controller itself to change Global Lock/Unlock
states.

Local Linkage Example – Trigger On Global Lock

The following trigger macro will execute whenever the Global Lock variable is changed
by the system:

This trigger can execute a local linkage procedure that can accomplish a number of dif-
ferent tasks. It can be used to turn off certain schedules that will deny access to a certain
group of cardholders (which will affect all cardholders assigned to that schedule). It can
also be used to change the mode of selected readers to something different than the
Global Lock type setting (configuring those readers to ignore the Global Lock/Unlock
command). There are many more macro possibilities that can be performed from this trig-
ger; essentially anything except turning off the trigger variables for Global Lock/Unlock.

Local Linkage Example – Prevent Trigger On Global Lock/Unlock

To stop certain local linkage triggers from executing when Global Lock or Global Unlock
is in effect, set the trigger variable logic as shown below:
