Police Dispatcher Practice Test

An "all units" call refers to a message that is sent out to all available units within a specific area or jurisdiction that requires immediate attention. This type of communication is crucial in law enforcement as it ensures that all officers or units on duty are alerted to a situation that may require their presence or assistance.

In emergency situations, for example, an "all units" call might be used to quickly mobilize available officers to respond to a crime in progress, a major accident, or another urgent incident. This approach maximizes the response capability of the agency involved, making it easier to deploy resources effectively.

The other options do not accurately describe the purpose of an "all units" call. While a system test, call for backup during a routine stop, or instructions for community events may involve communication to units, they do not encompass the urgency and broad reach of an "all units" alert.
