Hendricks County Fire/EMS Encrypts Dispatch: Scanner Delay in 2026
Hendricks County 911, a western Indianapolis suburb, announced in early August 2026 that it will expand radio encryption to its fire and EMS dispatch channels this September — pushing public scanner feeds onto a roughly 30-minute delayed loop. The move follows the county’s earlier encryption of its law-enforcement channels and makes Hendricks the latest agency in central Indiana to pull real-time emergency traffic away from the public.
Director Renee Tomlinson described the change as a way to “enhance the safety of emergency personnel.” At the same time, the county says fire and EMS traffic “will remain available through public scanner platforms,” but with location and sensitive details delayed by approximately 30 minutes — a lag that effectively removes listeners from live incident coverage. The announcement was quoted in full on the RadioReference forums and cross-posted by the county’s 911 office.
What Is Actually Being Encrypted
In a public clarification, Tomlinson confirmed that only the initial dispatch talkgroup (32F-DSP) is being encrypted for the public. Fire operations talkgroups, which carry the on-scene tactical traffic, are staying in the clear — at least for now. That is a meaningful distinction for listeners who follow incidents once crews arrive, even if they no longer hear the first alert that sends units out the door.
How the Decision Came Together
The county’s 911 advisory board voted on May 6, 2026, to recommend the move, with fire chiefs pointing to “scanner heads” showing up on active scenes as a driver. County commissioners then approved the plan in June 2026, according to reporting via the Hendricks County Scanner Facebook page, a secondary source the county has not formally disputed.
The concern cited by fire leadership is a familiar one across the country: real-time dispatch audio lets curious or opportunistic listeners learn exactly where units are headed, sometimes beating crews to the scene. Agencies argue that creates a safety risk; transparency advocates counter that delayed or dark feeds leave the public with no independent window into emergency response.
Scanners Keep Some Audio, Lose the Live Picture
Because only the initial dispatch talkgroup is encrypting and fire operations stay in the clear, Hendricks listeners will still hear meaningful on-scene traffic. What they lose is the real-time “first alert” — the moment a call is assigned. That first 30 minutes is often where the most important details are shared: the nature of the emergency, the exact location, and the severity.
Listeners have also noticed the county’s police feed delay was briefly bumped to 30 minutes before returning to its previous 15-minute delay. Whether that was a test or a configuration change is unclear, but it signals that delay settings can shift without public fanfare.
Part of a Broader Indiana Trend
Hendricks County joins a wave of Indiana agencies constraining real-time scanner access. Across central Indiana, departments and 911 centers have been moving toward encrypted or delayed dispatch, and the pattern has drawn the attention of scanner listeners and journalists alike. For anyone who monitors the Indianapolis metro, the takeaway is the same as in much of the country: the open, real-time feed you used to count on can change with a single board vote.
If you still listen to central Indiana, a reliable scanner that holds the remaining open talkgroups is worth having on hand — and worth keeping programmed as agencies shift channels.

Frequently Asked Questions
When does Hendricks County fire/EMS encryption start?
Hendricks County 911 announced in early August 2026 that it will expand encryption to fire and EMS dispatch channels in September 2026.
Will scanners still pick up Hendricks County fire/EMS?
Partially. Only the initial dispatch talkgroup (32F-DSP) is being encrypted for the public. Fire operations talkgroups stay in the clear, and public scanner platforms will carry fire/EMS traffic on a roughly 30-minute delayed loop.
Why is Hendricks County encrypting fire and EMS radio?
Director Renee Tomlinson said the move aims to “enhance the safety of emergency personnel.” The county’s 911 advisory board voted to recommend it on May 6, 2026, with fire chiefs citing “scanner heads” showing up on active scenes.
Is the public losing all Hendricks County scanner audio?
No. The county says fire/EMS traffic “will remain available through public scanner platforms,” but with location and sensitive details delayed by approximately 30 minutes. The county’s law-enforcement channels were already encrypted in an earlier phase.
Does this affect Indianapolis-area scanner listeners?
Yes. Hendricks County is a western Indianapolis suburb, and its real-time dispatch has been part of the metro’s scanner landscape. The delay removes the real-time “first alert” for fire and EMS calls.
Is Hendricks County unusual in doing this?
No. It is the latest in a wave of Indiana agencies constraining real-time scanner access, following similar moves across central Indiana departments and 911 centers.
Bottom line: Hendricks County is keeping fire/EMS audio on public feeds but moving it to a 30-minute delay as its dispatch talkgroup encrypts this September — the latest sign that real-time scanner access in the Indianapolis metro keeps narrowing.
