When there is an impending or imminent threat to campus, the University issues a NinerAlert. NinerAlerts are sent using a variety of methods, which are determined based on the nature of the threat. NinerAlerts are sent via University email, text message, digital screen take-over, the LiveSafe App, social media, and/or alert sirens. This mixture of communication avenues allows the University to reach the widest number of people during an emergency.

University Email

During an emergency, the only way for the University to ensure notification to every member of the UNC Charlotte community is via University email. Anyone with a University email account will receive this notification. It does not require registration. (Family members, please complete this form to sign up for email alerts.)

The University has equipped more than 8,400 on-campus computer and TV screens with an emergency alert software called Alertus. In the event of an emergency, this software allows the NinerAlert system to override current content with urgent information.

Emergency Sirens

The main campus has three emergency sirens that can be used to disseminate important information in the event of an emergency. These sirens are located at the Atkins Library, behind the Police and Public Safety/ Facilities Management building, and in the wooded area in between the EPIC building and Grigg Hall. When activated, the sirens will emit a loud siren tone followed by an audible voice message. While the tone and message may be heard inside some buildings on campus, the sirens are primarily designed to alert individuals that should take action. If you here the sirens activated, please immediately seek shelter and check the University website and/or University email for important information.

LiveSafe App

The LiveSafe app functions as a mobile bluelight phone with direct access to Police and Public Safety. The app can also function as an emergency alert tool by pushing information directly to users’ phones. Click here for more information on the app, including download instructions.
