My power supply to my alarm system is on a receptacle close to the attic ladderIt run through the attic to the master bedroom which has a high flat ceiling that slopes on two sides(no space except on sides where ducting is running) to a bathroom closet on the other side where it goes down a wall and powers the control box.and no, I don't want a wireless system.How do electricians/HVAC technicians run wire through such small spaces and then down a wall?
