icons will reflect the Global Lock/Unlock state. An operator with the appropriate per-
missions must change the state to Normal via the Situation Manager icon, hence the soft-
ware reset distinction. The following graphic shows the Situation Manager parameters to
set to enable this mode:

By setting the Global Reset Type to Momentary the hardware input now can trigger the
state change but cannot reset the system back to normal. This must be done through the
System Manager icons. Since Hardware Control is set to Software Has Precedence it is
still possible to initiate a Global Lock/Unlock from the Situation Manager icons.

Hardware Driven ONLY

For this application the system Global Lock/Unlock state is completely controlled by
latched input hardware. The Situation Manager icons only display status, they cannot ini-
tiate or clear a Global Lock/Unlock. The input hardware should be some kind of on/off
toggle switch. Hardware configuration consists of the doors to be assigned/unassigned
Global Lock/Unlock values and defining the inputs that control Global Lock/Unlock
events. The following graphic shows the Situation Manager parameters to set to enable
this mode:

Once configured, the system tracks multiple inputs over multiple controllers. If the system
is in the Normal state, the first Global Lock input triggered will place the entire system
into the Global Lock state. If another Global Lock input goes active, it is added to a list of
active Global Lock inputs. When the first switch is returned to Normal, there is no change
in the Global Lock state as the second switch is still active. It is only when all global lock
inputs return to Normal that the system returns to the Normal state.

As shown in the graphic above, Global Unlock Has Precedence. So if the system is in
the Global Lock state and one or more Global Unlock inputs are activated, the system
immediately changes to the Global Unlock state. The same input logic applies here as
with multiple Global Lock inputs. The system now waits until all of the Global Unlock
