Chesterfield County FD TAC Channel Question

[Jimru]

Hi,
I live in Henrico County, but have friends (and I sometimes work) in Chesterfield County, so I like to listen to Chesterfield FD from time to time. Although they are on the same system, they (Henrico and Chest FD) don’t seem to utilize TAC channels the same way. In Henrico, the automated dispatch channel will announce the incident and assigned units, then it will announce which TAC channel for the units involved to use. It seems that in Chesterfield, I’m hearing the dispatch voice announce incidents and apparatus assigned, but no mention of a TAC channel. Are there any regular listeners to Chesterfield FD here that can explain the seeming disparity? Thanks!

The database incorrectly labels some of the talkgroups. They changed some of the TG aliases when the new subscribers rolled out in 2018.

• 25392: Dispatch 1 - Phoenix system (computerized voice) & unit status changes
• 25408: OPS 1 - All small-scale incidents (medical, minor MVA/fire, etc. - a majority of calls for service are handled on this TG)
• 25424: TAC 3 - Significant incident 1 (structure fire, etc.)
• 25440: TAC 4 - Significant incident 2 (structure fire, etc.)
• 25456: TAC 5 - Significant incident 3 (structure fire, etc.)
• 25472: TAC 6 - Interstate assignments (any significant incident on an interstate - crash, etc.)
• 25488: Dispatch 2 - redundant dispatch channel
• 25504: OPS 2 - redundant operations channel
• 25520: TAC 9 - tactical 9
• etc.

Phoenix will announce the channel assignment for significant incidents, like structure fires, major crashes, etc. but not for routine incidents like EMS calls.

Although the radio system is shared amongst several localities, the automated dispatch systems are paid for and programmed by each locality. Henrico, Chesterfield, and Richmond all have their automated dispatch systems programmed to meet their needs, and each one also uses their Tacs differently. The post above describes Chesterfield's Tac plan very well.
