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 will be carried out through the use of e-mail, SMS (text messaging) and voice messaging, and sirens/public address systems.  

Emergency Notifications and Emergency Contact Information Enrollment:

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.


April 13, 2016 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.  There was an issue uploading the message to the social media sites. This is has been noted and will be resolved. 


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.
