Remain Calm.
All is well.
If you're on the Duke University campus Wednesday or Thursday, you may be startled by a blaring emergency alarm. University officials ask that you do NOT call 911; they're simply testing the new emergency response system they purchased recently.
The tests will be conducted Wednesday from 2 to 4:30 p.m., and Thursday from 8 a.m. to 4:30 p.m.
Sirens will sound intermittently. If you're outside on campus or close to it you may hear loud tones and live and recorded messages.
