I would like to fit a burgler alarm that is connected directly to the mains supply (as opposed to via a plug with a laughable pp3 battery backup). I want to know how exactly you figure out where the cables are, how you tap into them and how much damage to the wall is necessary? Do you need one of those devices that detect wires through the wall? How was it done before such things were invented?
Before now I've only changed a couple of light swtiches, a relatively simple affair since the wires are already there and I was coached by people on this forum. The height of my dad's DIY skill was sticky taping the brakes on my bike (turns out there are allen keys for such things!) so accordingly, my experience is limited.
