An EDACS Trunked System This chart shows how talk groups may organized within an EDACS system at the AGENCY level. The FLEETS and SUBFLEETS cannot be shown at this scale because there are 2048 possibilities. The system is logical and easy to understand. System users are given blocks of talk groups. Sizes vary but most large cities and other agencies have blocks of 128 channels. Smaller cities have only 64 or 32 channels. In this example, the County Sheriff is Agency 01. The city of Sullivan is Agency 03. Adams Hill and Matthew Junction share Agency 08. Your scanner shows EDACS talk groups in AFS (Agency-Fleet-Subfleet) format. This helps you see, at a glance, who you are monitoring. And with the XPAND feature (see page 50) you can easily include nearby, related channels in the same Fleet or Agency. Assuming that you have the system frequencies programmed, and your scanner is locked to the control channel, you can select a desired city by simply searching on the AGENCY part of the AFS talk group number. For example, you can select the entire city of Sullivan with 4 key presses zero, three, dot, SRCH. If you hear an interesting talk group, capture it to your scan list by pressing E during the transmission. If you want to monitor the Sullivan Police Dispatch channel (which is talk group 03-062), you key in zero, three, dot, zero, six, two, SRCH. Your scanner can switch between AFS and DECIMAL display. This channel, in decimal format, is 434. But decimal format does not give you any information about the system hierarchy. For example Sullivan, in decimal, uses channels from 384 to 511. This is not as easy to remember as Agency 03. But it will help you if you need to use decimal talk group lists. 84
