New security systems at entrances to Great Bend USD 428 elementary schools should be in place by the end of December, Superintendent Brad Reed said.Enhanced security at the middle school and high school will take a little longer.“We’re in the middle of a security audit,” Reed told the school board Monday. Administrators at the District Office have been talking with principals about how to secure the buildings.Earlier this year, the district had Dayton Security install a buzz-in system at Riley Elementary School. Assistant Administrator Khris Thexton said visitors press an intercom buzzer and are seen on camera by someone in the office, who can release the door lock so the visitor can enter the school.
