I'm not a huge fan of building electronics into buildings for the exact reason shown here. If something fails you can end up with defective energised electronics sitting inside a wall.
As with many similar items, when they go bang like this it often obliterates any clue as to what initiated the failure. It's just one big sooty skidmark inside.
