Addison Consolidated Dispatch Center (ACDC) is a Commission on Accreditation for Law Enforcement Agencies (CALEA)-accredited, consolidated public safety communications center serving police, fire, and EMS agencies. Based in Addison, Illinois, ACDC provides emergency dispatch services for nine police departments and seven fire agencies.

In addition to primary dispatch operations, ACDC handles after-hours 211 calls and coordinates callouts for Northern Illinois Critical Incident Stress Management (CISM), supporting responder wellness across the region.

Call 911 anytime there is an immediate threat to life, safety, or property. This includes crimes in progress, serious injuries, fires, and medical emergencies requiring urgent response.
The non-emergency line should be used for situations that still require police, fire, or EMS assistance but are not urgent or life-threatening. Examples include past incidents, delayed accidents, or general public safety concerns.

Your call is answered by a trained telecommunicator who will quickly ask a series of questions to determine the nature of the emergency. They will provide instructions as needed and dispatch the appropriate responders while staying on the line if necessary.

The questions help ensure responders are sent with the right information, equipment, and urgency level. While help is being dispatched, additional details can improve safety and response effectiveness.

The Premise Alert Program allows residents to voluntarily share information about individuals in their household who may require special consideration during an emergency. This helps telecommunicators and first responders provide more informed and effective assistance.

Residents who are away for extended periods can request extra attention to their property. Law enforcement may conduct periodic checks to help deter suspicious activity and provide peace of mind while you are gone.

Yes. Overnight parking requests can be submitted online when temporary parking is needed outside of normal restrictions. This helps ensure vehicles are documented and avoids unnecessary enforcement action.

MABAS (Mutual Aid Box Alarm System) is an organization that provides mutual aid to area fire departments. ACDC is the communications center for MABAS Division 10.
Staffing levels vary by time throughout the day; there are generally 6 to 9 Telecommunicators on duty at any given moment.

Do not hang up. Stay on the line and let the telecommunicator know the call was accidental. This prevents responders from being dispatched unnecessarily to check on your welfare.

If possible, be prepared to provide the location of the incident, what is happening, who is involved, and whether anyone is injured or in immediate danger.
