On a 6/22/2021 city council agenda item, a new system name is mentioned. "The City of Fort Worth operates a public safety radio system called the North Texas Interoperable Radio Network (NTIRN)."

As of 10/1/2010 the cities of Colleyville, Keller, and Southlake are sharing dispatch operations. For the police, it's handy to know the unit numbers. They are dispatched by "NETCOM" on the NETCOM Patrol 1 talkgroup on the NE Tarrant/Site 3 of the Fort Worth Regional Radio System. Update 8/2/2018, several of the NETCOM police and fire talkgroups are now carried on Layer 1(Site1) in addition to NE Tarrant/Site 3.

Police Department Unit Numbers

1##s Colleyville

2##s Southlake

3##s Keller, which also patrols Westlake

It sounds like the 2nd digit will be the shift for most of the patrol units.

18# Colleyville School Patrol

7## Southlake School Patrol

This is important to know now, because they are all on NETCOM PATRL 1.

Similarly, the cities of Richland Hills, North Richland Hills, Haltom City, and Watauga share dispatching for police, fire, and animal control officers (ACO) on shared channels on Layer 2/Site 2 of the Fort Worth Regional Radio System. Dispatchers address each city's units with the city name and then the unit number. For example, "North Hills 304". The first digit of 3 digit unit numbers are probably the shift number(need to confirm this). These units use NRHW Patrol 1 for their primary patrol channel.

Mansfield and Kennedale also share dispatching for their police and fire departments and can be heard on the Mansfield/Site 5 as well as Layer 2/Site 2 on the Fort Worth Regional Radio system. Mansfield police units are typically 4##s and Kennedale police units are typically 3##s, both on Mansfield Patrol 1. The second digit is often a letter that might correspond to the shift or beat.

Battallion chiefs and specialized units only use the first 2 digits("Battalion 24", "Heavy Rescue 56", etc.). Most others will be 3 digits, with the 3rd digit being the apparatus's station assignment. Example, Truck 153 is Bedford's Truck at station 3, Engine 201 is Hurst's engine at station 1.
