If Momentary, then no logic is needed for the restore state. The hardware input is
the trigger to put the system into a Global Lock or Global Unlock state, but the oper-
ator must clear the state using the Situation Manager icons on the ribbon bar.
1. To set the Global Reset Type, click in the Global Reset Type field in the grid and
select the Latched or the Momentary option in the pull-down menu.
Ignore Old Events
Sets the amount of time before the system considers a past Global Lock/Unlock event as
“old.” The intent of this option is to handle offline gateways/controllers that have global
inputs that were triggered at some point in the past but have yet to be reported to the sys-
tem. When they do report, it may be undesirable to initiate Global Lock/Unlock events
based on hardware inputs triggered in the past, especially if these inputs were being
used as momentary triggers. Global Lock/Unlock input reports that are deemed to be old
are not processed. This applies to events that are from the inputs that are designated as
either a Global Lock input or a Global Unlock input and does not affect operation from
the UI, Global Linkage, or System Calendar.
NOTE: If an input is not processed because it is considered old, it is possible to have the
input in one state and the system in another state. This condition should be handled by
toggling the input while the controller is online to reset its state.
The time period for designating an event as old ranges from Never to between 1 minute
and 24 hours. The default is Never.
l
Never means the incoming input state is applied immediately, following the rules
configured for the Situation Manager.
l
A time-period selection (1, 2, 3, 4, 5, 10, 15, 30, 45 minutes – 1, 2, 4, 8, 12, and 24
hours) means the GMT time stamp for the incoming input state is checked against
the system’s current GMT timestamp. The difference in minutes is compared to the
Ignore Old Events setting. If the number of minutes is greater than or equal to this
setting, the event is ignored and no Global Lock/Unlock processing occurs. If less
than, then the incoming input state is applied immediately, following the rules con-
figured for the Situation Manager.
1. To set a time period after which events are deemed “old,” click in the Ignore Old
Events field in the grid and select the desired time period from the list in the pull-
down menu.
Global Restore Trigger
Allows a Global Linkage action to trigger off of a Global Restore event; Global Linkage is
not triggering the Restore event, but is triggered by the execution of the Restore event.
This kind of trigger/action could turn on a relay, or send an e-mail or SMS message.
