Cornell University Emergency Mass Notification Systems

Cornell University is committed to protecting the health and safety of its students, faculty and staff.  Emergency procedures are in place that allow us to quickly notify authorities and the campus population when an emergency situation is underway and then provide instructions on how to respond.  These communications are carried out through the use of e-mail, SMS (text messaging) and voice messaging, CU VIew digital screens and sirens/public address systems.  

In our continuing efforts to provide state-of-the-art emergency communications to the University, we will begin introducing new technology from RAVE Mobile Safety during our October 2017 tests.

This integration will require additional testing to ensure that the systems are working as they are designed to do.  The campus community will be notified when a campus-wide test will be conducted.

Current enrollment procedures:

EMN systems are a critical component for emergency response. At this time, Cornell’s systems are managed as an “opt-in” program.  Every Cornell community member should be enrolled to receive messages.   

It is also very important to record emergency contact information for use by the Cornell Police in the event something happens to you.

If you have not yet entered your emergency notification and emergency contact information, please do so now.


October 25, 2017 EMN Test Results:

The test of the siren/PA systems was successful with all four sirens firing and annunciation reported to be within acceptable limits.  The test of the voice and sms (text) messaging campaigns was successful.  


To contact the Cornell Police:

Call 911 (from campus phones), 607-255-1111 (from cell phones or off-campus phones) or pick up one of the Blue Light phones installed around campus.  Calling 911 from a cell phone will connect the caller to the Tompkins County emergency dispatcher, who will forward the call to the Cornell Police.  Dial these numbers to report incidents such as an accident, a serious injury, a crime in progress, a fire, or chemical spill. 

Campus-wide Emergency

When there is a significant emergency or dangerous situation involving an immediate threat to the health or safety of the University community, an Emergency Mass Notification (EMN) is written and distributed without delay to the entire University community using one or many of the campus EMN systems.  An EMN notification would not be distributed only if it could compromise efforts to contain the emergency.

Weather Emergency

In the event of an adverse weather condition such as a blizzard or ice storm, you should check the Operating Status web page ; for status of University operations.  Condition updates such as delayed university openings, road closings, and university closings will be available on this site, and, through subsequent e-mails and local media as necessary.
