To assure that Georgia Tech's Siren Warning System is in continuous operational condition, the Office of Emergency Preparedness will begin testing the system today at 11AM. All seven speaker stations will be tested simultaneously playing the following test message twice: "Attention. Attention. This is a test of the Georgia Tech Emergency Notification System. This is only a test. This is a test of the Georgia Tech Emergency Notification System. This is only a test." In addition, if you subscribe to the Georgia Tech Emergency Notification System (GTENS) through phone or e-mail, you will receive an email message, a voice message and a text message. The System to Create and Relay Emergency Action Messages (SCREAM) will provide an alert message to classroom projectors logged in to the GT network, computer clusters on campus and digital signs around campus. Finally, the Georgia Tech Cable TV Alert System will show a test message for 30 seconds.
