Appalachian State University will test its campus siren warning system at 11:55 a.m., Wednesday, March 7.

Appalachian uses the hi/low tone for emergencies, discontinuous air horn for tests of the system and the alert tone for all-clear signal.

The siren tests are conducted on the first Wednesday of each month.
