Outdoor Public Address System

In 2009, EMU installed seven outdoor speaker arrays that provide voice messages to the outdoor areas of campus. These high powered speakers use scripted messages to alert the campus to hazards and provide information on how to respond. The system is operated by the EMU Department of Public Safety.

Halle Speaker ArraySpeakers are located on top of Phelps Hall, King Hall, Goddard Hall, Halle Library, the Student Center, the Convocation Center and next to the Sculpture Studio. Though the speakers are extremely loud, they are not designed to be heard indoors. They are intended to alert people outdoors to an emergency.

When activated, you will first hear a two tone sound followed by a message. The tone and message will repeat multiple times depending on the event taking place. Please follow the directions given by the system.

EMU conducts monthly tests of its mass notification & emergency communications system. Activation of the system includes an audible test message to all outdoor speakers and to designated in-building speakers. A full system test (all indoor and outdoor speakers and the EMU Alert text and email messaging system) takes place during the January and September tests.

Testing is scheduled at 12 noon on the 4th Friday of the month  (except when adjustments for holidays and  in December when testing will be on the second Friday of the month).  Typical duration of tests is approximately 2 minutes.
