For the first time, Cornell's sirens/public address system was tested simultaneously with emergency voice and text messaging Nov. 12 at 12:10 p.m. As the four sirens blared across campus, the test message was launched and 17,147 messages were delivered to carrier networks within 14 minutes.

"All units worked as expected," said Richard McDaniel, vice president for risk management and public safety. "We will review these test results over the coming days and continue to try to improve the systems."
