Public address system is used to evacuate employees in case of a fire, bomb, and poisonous gas or any spillage which poses a safety and health hazard. When linked to a fire evacuation system, it automatically alerts building occupants of a fire hazard.

The system can also be used to page occupants of a building as well as playing background music. When an emergency is detected, background music is automatically muted.
