House full of an old security system bits. How easy to remove? (infosec.pub)

I tested this with an electrical socket reader and it chimed, so there is some power to it still. I'd like to remove this, the old keypad, a siren, etc.

Besides shutting off the power while doing it and maybe capping the cable ends, what do I need to think about? I'm just trying to make sure I don't burn my house down 😅

Your electrician eyes would be better than my non-electrician eyes...

But is that home power wiring? That looks closer to thermostat wire to me in that picture. Colors are wrong though so...

Edit: I for sure wouldn't touch these though. You can probably use a meter across the 4 terminals without even having to disconnect anything. It might just be the kind of wiring that you use for a 3 way switch with the ground wire sheathed. What was the device?

No it's probably 18ga, but it could have 120v on it from the panel, with very little current.

Yeah test across the terminals first

Edit: yeah looks like 18/4 shielded I think

It's "station Z" wire which is 4c/22awg, which has been super common in residential alarm installation for forever.

There's the stuff my company orders en mass.
