An upstate teenager whose cousin died in the Parkland, Fla., massacre is pushing a state bill that would force public schools to install silent panic alarms to alert law enforcement when an active shooter is on the loose, she told The Post on Monday.

Jadyn Turner, a 15-year-old from Nyack, and her dad, Jordan Turner, are relatives of Alyssa Alhadeff, one of the 17 students killed at Marjory Stoneman Douglas High School last year.

“It would’ve helped save some of the lives lost in Parkland,” Jadyn Turner, a freshman at Nyack High School, said of the panic alarm. “I want to know my school is doing everything possible to keep us safe.”

The legislation, which is similar to a bill that passed in New Jersey earlier this year, has already garnered more than 20 legislative sponsors and is currently in the Senate and Assembly education committees.

Under the bill, a silent alarm would send a message to cops when students are in danger. Advocates say it would result in quicker response times from law enforcement during active shooter cases and in other school emergencies.

Sen. David Carlucci (D-Rockland), who sponsored the bill, said it will also help ease fears inside classrooms.

“The anxiety has boiled up,” he said. “It seems like every week there’s a school shooting. It puts a chilling effect on the whole education system … We have to give [students] this sense of security. You can’t learn, if you’re in fear.”

The slain teen’s parents, Ilan and Lori Alhadeff, helped get similar legislation, known as Alyssa’s Law, passed in New Jersey in February.

The Turners are optimistic the bill will pass here eventually, but aren’t sure it will happen this session, which ends June 19.

“It’s a way to honor my cousin,” Jadyn said. “Hopefully it’ll save other kids from shootings.”
