DU-COMM and Consolidated Services

DU-COMM has been a model of efficient government and consolidated services for over forty(40) years.  During all of that time and even before the 1989 formation of the DuPage Emergency Telephone System Board (ETSB), municipalities and fire districts have worked together to provide a high level of service to their citizens in public safety communications.  Nothing demonstrates this more than during the last eight (8) years eighteen (18) agencies joined DU-COMM to benefit from the cost savings and improved service. Interagency cooperation, efficiency, and shared governance have all been successful within DU-COMM model.

DU-COMM and the DuPage Emergency Telephone System Board (ETSB)

DU-COMM is supported by the DuPage Emergency Telephone System Board (ETSB), which funds much of the infrastructure in the center, including CAD (Computer Aided Dispatch) and Motorola STARCOM21.  DU-COMM is one of two 9-1-1 centers, or PSAP’s (Public Safety Answering points) in the DuPage ETSB system, but as the largest center, DU-COMM accounts for seventy-five percent (75%) of all police and fire agency’s in the ETSB system.

Our Facility

DU-COMM is located in a new facility on the DuPage County Campus. The facility was operational in August of 2018. The new facility has over 34,000 sq feet of space including a weather hardened Communications Center and support space for our employees. The Communications Center has 34 dispatch consoles.

Radio Frequencies

DU-COMM operates on a variety of communications systems. In 2012 we moved our communications onto the statewide STARCOM21 system as part of the DuPage ETSB Interoperable Radio System.


DU-COMM is the dispatch center for M.A.B.A.S. Division 12 and Division 16. M.A.B.A.S.(Mutual Aid Box Alarm System) is a Fire/EMS mutual aid system that has existed since the late 1960's. During major incidents DU-COMM acts as the single point of contact for either division and coordinates the responses.
