Hendricks County (IN)


County-wide Dispatch System

All Hendricks County public safety agencies use Indiana Project Hoosier SAFE-T (Motorola) for dispatch and tactical communications. All dispatching is handled by the Hendricks County Communications Center located in Plainfield. There are two SAFE-T sites in Hendricks County--one in Plainfield and one northwest of Danville. They are operated as a simulcast system in that both towers use the same frequencies and handle the same traffic.

In addition to the Project SAFE-T talkgroups, Hendricks County Fire radios are programmed with 853.0125 MHz FM simplex PL 156.7 Hz as a talkaround channel. This channel is often used as a Fireground channel where SAFE-T repeater coverage is poor.
