Appalachian State University will test its campus siren warning system at 11:55 a.m., Wednesday, July 11.
Examples of the tones that are used in an emergency or during tests can be heard online at https://emergency.appstate.edu/siren-warning-system.
Appalachian uses the hi/low tone for emergencies, discontinuous air horn for tests of the system and the alert tone for all-clear signal.
