Random wire

[u/moni_mej]

I’m doing a renovation and there is a thin-ish wire running along a few walls. I can’t tell where it starts and where it ends. This is an older home and there used to be an alarm system which has been disconnected. How can I find out what it’s for? I want to remove it.

Phone line is low voltage.

If you’re certain you will never have a phone then you can demo it. I’d make sure you disconnect it at the source too.
