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 ๐
Just don't short them. If you leave the cables in (why not; it sucks to add new ones into walls, if you need them later), make sure the ends are somehow shielded and don't touch, i.e. add a clamp to the end or wrap it in electrician's tape.
