The act was sponsored by State Representatives Scott Baltz and Bruce Cozart.
School administrators will approve who has access to the panic button app on their phone.
The phone app will alert 911 immediately as it works hand in hand with the state's Smart911 program.
Since floor plans will be loaded into the Smart911 system, first responders will be able to pinpoint where the emergency is and better protect students in the more than 1,000 public schools nationwide.
Jonesboro E911 Director Jeff Presley said the program has been started in the Jonesboro area schools.
He said those districts were among the first in the state to go live with the program.
Presley called it “a great day for our schools and public safety.”
