An Act amending the act of March 10, 1949 (P.L.30, No.14), known as the Public School Code of 1949, in school safety and security, providing for panic alerts.

HB 653, known as Alyssa's Law, requires all Pennsylvania public school buildings (including elementary, middle, and high school campuses) to install silent panic alert systems. These systems must be manually activated via devices like buttons or apps and immediately send emergency alerts directly to designated local law enforcement responders during security threats like active shooters or lockdowns. The law defines "panic alerts" as silent notifications for life-threatening emergencies and specifies that the alert must link to first responders on the school's campus. This mandate applies to all buildings used for instruction during school hours, replacing vague prior security language with a concrete equipment requirement.
