ILLINOIS LAW ENFORCEMENT ALARM SYSTEM
One of the primary missions for ILEAS is to coordinate statewide mutual aid for law enforcement in Illinois. For years, police and sheriff's agencies have worked together locally and developed literally dozens of different mutual aid arrangements. Over 20 years ago, agencies north and west of Chicago formed a mutual aid organization called the Northern Illinois Police Alarm System (NIPAS). It was based on the Fire Mutual Aid Box Alarm (MABAS) that had existed already for many years. Over time, NIPAS grew to include dozens of police agencies.
Mutual Aid Box Alarm System
Oak Lawn Central is the MABAS Division XXI dispatch headquarters of the Mutual Aid Box Alarm System, which began in 1968. There are currently 48 divisions throughout Illinois and 4 divisions in Wisconsin. As time goes on more divisions in these and other states are likely to form. MABAS allows Oak Lawn Central to communicate with and receive assistance from many non-Oak Lawn Central fire agencies during major incidents.
