One of Illinois' largest school districts will outfit its buildings with new wireless alarm technology this summer as a safeguard against violent intruders.
If a gunman enters one of Plainfield District 202's 30 schools this fall, the principal could press the electronic pendant on the lanyard around her neck. Or an office worker will be able to tap the wireless panic button beneath his desk.
A tone would echo through the school's public address system, telling teachers and students to go into their intruder lockdown protocol. Fire doors would swing shut, cutting off the intruder's path. At the same time, police would be alerted.
In a post-Sandy Hook world, district officials say the alarms are a way to improve security, reassure parents and not break the bank in the process.
