ok I know this is an electrical forum.But if anyone can help id appreciate it. I got a call to a water damaged house. leaking pipe and the contractor had to open up all the walls in a bed room. The house had no hard wired smokes. In Mass. I know that when you alter a bed room you have to update the smoke system. The insurance company is looking for the code article that for a reference. Its in the build code not the electrical and I don't have one...….. can anyone help me out
