Some City Council members want to make sure all exterior doors in elementary and special education schools have alarms on them.
The Audible Alarms Bill comes in the wake of the disappearance and death of Queens teen Avonte Oquendo.
The bill hopes to safeguard students living with autism and particularly, those who wander, are non-verbal or have trouble communicating.
Officials say six young children with disabilities walked out of their schools without officials' knowledge in this year alone.
"While we celebrate (universal pre-K), we're going to have an influx of four- and five-year-olds by the thousands who will be entering these school buildings in the fall, and we want to make sure that they're safe," said City Councilman Robert E. Cornegy Jr. of Brooklyn.
"So as far as all these security buzzers, I find it's a necessity," said Regina Castro, a member of the NYC Parents Union. "I thank all the Council people that also thought it was a necessity."
The bill has 46 sponsors in the council.
