Cornell will conduct a full-scale test of its new emergency siren/public address system on Wednesday, April 30.

The test will take place at 11:05 a.m. and will involve the four siren assemblies located on the roofs of Hans Bethe House, Mary Donlon Hall, Bartels Hall and the Veterinary Medical Center.

The test will begin with the broadcast of a 25-second prerecorded message saying, "This is a test. This is a test of the emergency warning system. This is only a test. This is a test of the emergency warning system. This is only a test." The message will be followed by an alert tone that will sound for 60 seconds and a repeat of the prerecorded message. A sample of the alert tone can be accessed at http://www.epr.cornell.edu.

The tests will be conducted by technicians from Mid-State Communications, Cornell Police and Facilities Services.
