In addition to nearby active shooter and armed intruder emergency alerts, the Hero911 app also provides non emergency Nationwide Situational Awareness Messaging System (NSAMS) alerts to provide information to all first responders in the Hero911 Network about shootings happening all across the country.

This alert is an information only alert to provide situational awareness of mass shootings nationwide. It is not intended to be an emergency alert, however if this alert goes off with an emergency in your immediate, area first responders may choose to respond.

Since active shootings take place more often than most people realize, the NSAMS alerts is designed to provide information about these shootings happening around our nation.

The alert contains short details about the shooting and a link to the NSAMS alert on the Hero911 site to view more information about the alert.
