PSAP Talkgroups

TACN provides free access for Public Safety Answering Point (PSAP) talkgroups. Using a TACN PSAP talkgroup, any public safety dispatch, including law enforcement, fire, and EMS, can communicate with their officers in the field and any other agency that has access to the talkgroup.

TACN’s PSAP talkgroups are an alternative to using an intercity channel or telephone. Unlike intercity channels, which are reserved for law enforcement dispatches, TACN PSAP talkgroups can serve local, state, and federal first responder dispatches. Talkgroups are P-25 Phase I (FDMA), unencrypted and cover specific regions of the state. Dispatches can access multiple TACN PSAP talk groups.

PSAP Talkgroup Requirements:

  • Low power P-25 Phase I trunked capable radio or consolette - low gain antenna at 20’ or less in height to affiliate to the nearest TACN tower site.
  • Talkgroups can be programmed into any mobile command vehicles or mobile communications vehicles.
  • Several manufacturers provide radios that work on the TACN system, including Kenwood, Harris, Tait, E.F. Johnson, and Motorola.
  • TACN can provide the state system radio programming for free. A local radio shop can provide the radio and any installation and configuration to a console system. TACN can work with your local radio shop to ensure the installation is completed and operational.

Contact TACN administration to determine which is best for your agency.
