Well, there's an easy way to find out. Hook it up and try it out. Try it on your cheapest speaker first just in case there are issues. If it doesn't work, just hook up one speaker at a time to your receiver and you'll easily find out which is which.

Well, I don't have a toner. I was going to buy one if this would work.

I don't have any cheap speakers so don't want to fry anything, I didn't think damage was an option, I just thought the toner would sound a beep or not. But maybe it could damage the speakers, and I could end up damaging all my speakers without realizing it.

Hooking up one speaker at a time to the receiver is a pita, which is why I want to use the toner. I have hundreds of wires in my equipment closet. Connecting each to my receiver one at a time would be a nightmare. The toner will take time too but it would go faster.

Hundreds of wires? Damn, do you have like 10 rooms with full surround systems in each one? There are threads online from other forums. Most say to unhook your speakers to tone out, but i did see one youtube video doing exactly what you asked about and it worked. Proceed at your own risk.

My point for you to try it was not to try all of your speakers and then test them for damage. Test one, and check for damage.

And I dont understand how hooking each up speaker to your receiver would be any different than using a toner you dont have. Connect a speaker wire to your receiver to one set of terminals, and attach some alligator clips to the other end of said wires. Then connect one set of wires at a time to the clips to find your speaker locations. Easy peasy

I like your idea of attaching alligator clips to speaker wire, that makes sense. I will probably do that.

I have many sets of speakers all over, network cable, alarm, automation, cameras, etc. Here's a photo of the wiring into the equipment closet. Maybe not hundreds as in 200+ but over 100.

That much cable and no labels? No schematic left from the install? Bad Home Automation install if you ask me. All of that should have been provided. And to answer your question yes the Tone and Probe kit will work as you concluded.

What do you mean about schematic? What kind of schematic should I have?

Many/most of the wires are labeled. Nobody said they aren't labeled, although I can see how you could make that assumption.

You wrote, “but they aren’t labeled”

Yea I was responding to you saying that they were not labeled. If they are labeled then great-- don't even need a tone and probe kit.

On the schematic, typically there is a schematic used to design all the wiring in the home. Once the install is finished, that schematic should be left with the homeowner, much like the rest of the architectural plans.

OK, my bad. I did say they aren't labeled just to keep it simple.

The reality is many/most of the wires are labeled. But as you can see they are neatly and tightly bundled (you can also see a few labels in the photo) so I can't see most of the labels without making a giant mess in there. I just said they are unlabeled to make the point that I have no easy way to identify what leads to where.

With a toner (or the alligator clip suggestion) I can test each of the wires in place without disrupting anything util I find what I am looking for.

I'm still unclear on the schematic. It is obvious where all the components are and where the wires lead to. Are you saying I should have a schematic that shows the exact path of every wire from point A to point B? Isn't knowing where point A and point B is sufficient?

This isn't a new construction job, it was a huge retrofit. I think asking them to diagram every wire as they were installing it would have been unreasonable and really slowed things down or made it way more expensive. Once everything is working, what is the purpose of the schematic?

Thank you.

Now that you say they are labelled, and it seems they're all in bunches. if the cablers were nice to you, then they bundled them by room or purpose so it might be easier than you think. See if you can read a couple labels in each bundle to see if that lines up. If so, just undo one bundle at a time and terminate as needed. Make sure to use some hook and loop, don't use zip ties like what's being used now especially for cat5/6 as it can pinch the wires and degrade service.

Not only is it gentle on cables, it allows you to readjust or add cables easily as needed.
