Event Groups
An event group is a collection of playback events that require different mix/attenuation properties than a
standard event. Use event groups to sequence alarms when multiple events are active simultaneously.
The maximum number of event groups is 16. There are three types of event groups; standard, sequenced,
and contingent override.

Event Group Description
—user-defined unique description of the event group. This name identifies the
event group in all areas of the system.
Type: (of Event Group)
•
Standard
—included events can have
mix/attenuation
properties that differ from the
Global
Mix/Attenuation
properties. Use standard event groups for various scenarios when the
implementation requires unique
Mix/Attenuation
properties.
•
Sequenced
—active events play in sequence if more than one event in the group becomes active.
Active events in the group will effectively take turns playing as long as they are active.
•
Contingent Override
—initiate an alternate event if more than one event in the group becomes
active.
The contingent event must have a higher priority than the group. For example, if multiple fire
alarm events within the group initiate; the contingent event overrides the active events within the
group.
