Several years ago Parma moved it's safety forces from it's EDACS system to a new P25 system.
Currently Parma's Project P25 system hosts, Parma PD, Parma Fire, Brooklyn PD, Brooklyn Fire and Parma Hts PD.
If you go to the Databases - Frequency Database - Ohio - Cuyahoga County web page and scroll to the bottom, you will see Parma P25 listed with the other trunked systems.
