Metropolitan Emergency Response and Investigative Team (MERIT)

County-wide task force charged with leading investigations into serious crimes, critical incidents and other law enforcement endeavors. Created in 2019, MERIT is a consolidation of law enforcement specialty teams including FIAT, IMAT, DuCART, the DuPage County Major Crimes Task Force and the DuPage County SWAT Team. MERIT consists of ten components, namely, SWAT, Crisis Negotiation Team, Canine Response Unit, Incident Management Assistance Team, Planned Events, Major Crash Reconstruction Team, Major Crimes Unit, Public Integrity Team, Forensics Investigation Unit and Digital Forensics Unit.

  • It is believed that they use at least two encrypted STARCOM21 talkgroups (2642 and 2643). SWAT personnel were seen using what appeared to be (from the antennas) small VHF radios during an exercise in October of 2019. The SWAT team's predecessor (FIAT) was confirmed using 155.415 (146.2 PL) in the past.

Frontline rigs use radio IDs that match their respective station numbers (i.e. Engine 38 is housed at Station 38, etc.). In addition, some departments have designated response areas which are outside of their city, village or district boundaries ("closest unit"). For example, Wheaton units will be responding to some areas of Winfield and Carol Stream and Winfield will be responding to some areas of Wheaton and Carol Stream, etc. More information on these changes will be posted at the "DuPage County Fire Station Numbering" heading (bottom of this page) as it becomes available.

  • The administration recommended the MOTOTRBO system, equipping each building with a desktop radio hardwired to an antenna and supported with battery backup. Installation of centrally located roof-mounted repeaters would extend signal range, making the system stronger and more reliable than their current analog two-way system and would allow communications among district buildings and with emergency personnel, providing coverage throughout the entire district.
  • The radios, with dual analog-digital capability, allowed users to easily switch over to analog mode to seamlessly communicate with personnel still using the old analog radios, enabling a cost-effective migration to all-digital. Each of the schools, as well as the district office and the transportation office, were issued a MOTOTRBO digital portable radios, along with eight desk top control stations that are used by the schools’ administrative personnel.
  • The radios also allow staff to increase efficiency through better coordination of school activities, such as assemblies, sporting events, school bus loading/unloading and cafeteria peak periods. Teachers, bus drivers, crossing guards and coaches can deter, or take immediate action as needed, when disturbances or emergencies occur.
  • Our buses are operated by First Student Bus Transportation Services and we gave their coordinator one of our radios too. That allows us to maintain contact with the buses as well.”
