# Aggregate Alarm Levels

Object lists and objects have aggregate alarm levels.

The aggregate alarm level of an object list reflects the most severe alarm possessed by any object in the list.

The aggregate alarm level of an object reflects the most severe alarm possessed by the object.

### Object List

An object list is a collection of similar objects. For example, one object list might contain all the Agent Groups that handle inbound telephone calls, and another might contain all the Agents in a given Agent Group.

An object list has a list-centered aggregate alarm level. This level is defined by the most severe alarm possessed by any object in the object list. For example, if a given object list contains all the Agents in an Agent Group, the aggregate alarm level of the Agent list reflects the most severe alarm possessed by any Agent in that Agent Group.

### Group Object

A group object contains other objects. For example, Agent Groups and Place Groups are group objects.

A group object has an object-centered aggregate alarm level. This level is defined by the most severe alarm possessed by the group object itself. For example, the aggregate alarm level of an Agent Group object is based on the most severe alarm possessed by the Agent Group object itself (as opposed to the alarms possessed by the Agents in that Agent Group).

### Terminal Object

A terminal object does not contain other objects. For example, Agents and Places are terminal objects.

A terminal object also has an object-centered aggregate alarm level. This level is defined by the most severe alarm possessed by the object itself.
