Requires silent alarms to be installed in all school classrooms

This bill requires all public and nonpublic schools in New York State to install silent alarm systems in every classroom. The systems must include a button teachers can press to alert local law enforcement and school administrators during emergencies, without producing any audible sound. It defines "silent alarm" specifically as a security system that triggers silent alerts to authorities. The mandate applies to all school districts, charter schools, and nonpublic schools, with installations required in locations easily accessible to teachers. The bill takes effect immediately upon enactment.
