Indianapolis Fire/EMS dispatches for all Marion County Fire Departments, except Eli Lilly Fire/Rescue, City of Lawrence Fire/Rescue, and the Indianapolis International Airport Authority Fire/Resue.   IFEMS has Mutual Aid agreements with Lawrence Fire and EMS, as well as surrounding areas Fire/Rescue agencies and can Dispatch their units on Mutual Aid Calls, and vice versa. This occurs on both the IDPS TRS, and the SAFE-T TRS.  **IFEMS Dispatch is simulcast on IDPSC Mutual Aid talkgroups.**
