I occasionally hear acronyms or terms used during fire/rescue calls.

Most common I hear are BLS, ALS, MVA, and yesterday, a call for “Man vs. Machine” (call details were a little ugly).

I looked up what these are, but is there a web site or wiki dedicated to listing/describing these type of things you might hear on a scanner?

I found this article with a list of 600 acronyms:

You have a long road to study.
1.MVA = Motor Vehicle Accident
2.BLS = Basic Life Support
3.ALS = Advanced Life Support
Let me guess you do not know what CPR stands for either.
How about Full Code?
When you get old enough you might like EMT School.

Thanks. Yes, 1-3 those I know as I looked them up, and of course CPR. But I was looking for a central source for future reference as new ones pop up - if it exists.

Full Code? I’m guessing someone has flat-lined? Or in Cardiac arrest?

Making it a tad more complicated, terms vary by location. Around these parts a "Truck Company" means a fire apparatus with a mounted ladder, lots of ground ladders and primary assignment is search/rescue/ventilation. Other parts of the country would call this apparatus a "Ladder Company".

Then you got terms like "First Alarm Assignment", "Box Alarm", "Silent Alarm" and "Still Alarm". All meaning different things owing to where you are.

It's not as easy as "here's a list"
As others have indicated, there's *LOTS* of local variability (e.g. "tanker" vs "tender"), varying 10-codes, unofficial acronyms that get used occasionally on accident (e.g. DRT - "dead right there"), and so on.
You'll have to use context clues from the "big picture" that you're hearing. Sometimes you'll have to come right out and ask someone who was (or could have reasonably been) involved, which means having someone involved in the public safety world close to you.
You stated that you looked up a few and so you know them now - that's basically the process. Look them up, get some ideas, and use the context of the call to figure out if the answers you're getting are reasonable.

I found this article with a list of 600 acronyms:
I've heard many different codes for deceased person: 10-60 Notify Coroner, 10-63 Dead Body, 10-7 Out of Service, Signal 53 Dead Body, November Charlie, November Tango Charlie "Notify the Coroner"; Medical Code is Signal 9 DOA, No Transport, Signal 10 DOA, Transport; The best one I heard on Deputies car to car: "He's Dead, Jim!".

Heard a new term this morning (telephonics) monitoring the Fitchburg, Massachusetts FD.

Asked Duck.ai:

GPT-5.6 Luna response
In a city fire-department call log, “telephonics” usually means the call was received by telephone—for example, through 911, a non-emergency line, or another agency—not automatically by an alarm system, radio, or in-person report.

It describes the source or method of notification, not necessarily the type or seriousness of the incident. The exact meaning can vary by department’s CAD system, so a specific city’s records may define it slightly differently. Fire dispatch centers commonly take calls by phone, enter them into a computer-aided dispatch system, and then send units by radio or station alerting.


2nd Opinion:
Gemma 4 response

In the context of a city fire department or emergency dispatch system, **telephonics** refers to the technical infrastructure and communication systems used to receive, process, and transmit emergency calls.

When a dispatcher or fire officer mentions "telephonics," they are usually referring to the hardware and software that facilitate the link between the caller and the responders. This typically includes:

* **The Public Safety Answering Point (PSAP):** The physical location (dispatch center) where emergency calls are first received.
* **Automatic Number Identification/Automatic Location Identification (ANI/ALI):** The systems that automatically provide the dispatcher with the caller's phone number and geographic location.
* **Computer-Aided Dispatch (CAD):** The software that takes the telephonic data and matches it with available fire units and the closest fire station.
* **Interoperability:** The ability for the telephone system to communicate with different radio frequencies or other agencies (like police or EMS) during a major incident.

If you see this term in a report or hear it during a call, it is likely referring to a technical aspect of the communication chain rather than a specific type of emergency. For example, a "telephonics failure" would mean there is a technical glitch preventing calls from reaching the dispatch center or preventing location data from appearing on the dispatcher's screen.
