And until very recently, these were NOT in use on locution, or aural dispatching for IFEMS. Only time you heard any codes were when an incident code was changed while the units were en route, and control would announce the change. About a week ago, this changed, and now ALL medical response calls have the letter code added. A lot of changes have occurred rather recently. No longer are IFEMS FD OPS TGs called FD OPS XX... They are now just OPS XX. Only Speedway, and Airport FDs still have any other designations. Airport is Airport FD OPS XX... Speedway is still SFD OPS. Most if not all IFEMS MDT/Laptops have been taken in to be redone, or replaced in last week or so also. This indicates some changes with the CAD system finally. And in the not to distant future, Pulse Point will begin use with IFEMS, as well as Westfield FD in Hamilton County.
