Metro Fire Dispatch Changes and Tac Channel Usage

In the last week or so, Savannah-Chatham Metro Dispatch and the municipal fire departments that they dispatch have made some modifications to how the departments are dispatched and the radio channels they operate on.

Previously, Garden City FD, Isle of Hope FD, Port Wentworth FD, and Thunderbolt FD were dispatched on the Metro Fire Dispatch talkgroup (of the Chatham-Effingham TRS) 3568. Pooler and Bloomingdale FD were dispatched on the Pooler FD talkgroup 5424. Over the last week, I have noticed that all of the above are now being dispatched on talkgroup 3568 (a change that makes complete sense, it must have been a pain for the dispatchers to switch talkgroups when working with the different departments).

They are also making use of the Fire Tac channels that have been listed for so long in the Radio Reference database but never heard. Once the units have been dispatched and arrive on scene to an active incident, Metro Dispatch pushes them to one of the Fire Tac channels for their fireground operations. The use of the Fire Tac channels keep tactical traffic off of the dispatch channel and enable Metro Dispatch to know where to find the units to do safety checks and communicate with the incident commander.

3632 = Fire Tac 1
3664 = Fire Tac 2
3696 = Fire Tac 3
3728 = Fire Tac 4
3760 = Fire Tac 5
3792 = Fire Tac 6

Agency Monitoring Profile: Westside Chatham County Fire Departments

This article was originally written for the November issue of Key Klix, the newsletter of the Amateur Radio Club of Savannah.

Bloomingdale Fire Department, Garden City Fire Department, Pooler Fire Department, and Port Wentworth Fire Department are the four municipal fire departments on the west side of Chatham County. All four departments are dispatched by Savannah-Chatham Metropolitan Police Department.

All of the westside fire departments are dispatched using the Chatham-Effingham Trunked Repeater System and VHF repeaters. Garden City FD and Port Wentworth FD are dispatched using Metro Fire Dispatch talkgroup (3568) on the Trunked System and on the 154.385 Metro Fire Dispatch Repeater (Isle of Hope Fire Department and Thunderbolt Fire Department are also dispatched using this talkgroup and repeater combination). Pooler FD and Bloomingdale FD are dispatched using the Pooler FD talkgroup (5424) and the 154.145 Pooler/Bloomingdale FD repeater.

The westside Fire Departments use callsign structures that indicate which department the personnel are from. Likewise, the apparatus and units of each department are numbered to indicate which unit they belong to. The callsigns and unit numbers correspond to the callsigns of the respective city Police Departments, making identification easier for everyone involved. 1000 is added to the PD callsign group to get the FD callsigns; for instance Garden City PD uses 2## callsigns and Garden City FD uses 12## callsigns. Apparatus and Unit numbers are two digit numbers that begin with the first digit of the PD callsign/second digit of the fire department callsign; for example Garden City's apparatus/unit numbers are 2# units.

16## Pooler Fire Department

West Chatham County Fire Department Callsigns and Unit Numbers

Since the beginning of the year, some of the West Chatham County Fire Departments have changed their callsigns and unit numbers. It appears that they have done this to align their callsigns with their respective Police Department callsigns. This numbering should also have the effect of making the department more easily recognized without using the city name along with the callsign.

It is worth noting that Garden City FD has used 12## for some time. The other department's use of 18##, 16##, 14## respectively is much more recent.

Bloomingdale Fire
8## - PD Unit Numbers
18## - Fire Department Personnel
1#, 2# - Unit Numbers

Garden City Fire
2## - PD Unit Numbers
12## - Fire Department Personnel
1#, 2# - Unit Numbers

Pooler Fire
6## - PD Unit Numbers
16## - Fire Department Personnel
6# - Unit Numbers

Port Wentworth Fire
4## - PD unit Numbers
14## - Fire Department Personnel
