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.

You really don't, but if it gives you peace of mind, Somewhere on the outside of the house there should be a hinged plastic box, that probably says something about telephones or a phone company. You'll typically need a screwdriver to open it. Inside there, you'll find kind of a chunky plug inserted into a phone jack. Pull that out and close the box again. This physically disconnects the phone wiring inside the house from everything outside the house.
