6core runs behind consumer unit and comes out at a small hole at bottom just next to the bell transformer. (Which is wired up to the door bell) the 6core runs back to store/cupboard with all other alarm cables ready to be wired in. I was just trying to figure out what the previous spark had intended this to be for. Wer the alarm is to be situated he has left a fsu which goes back t&e to the cu.
