A customer called that had a whole house Nutone intercom, in Sparta, NJ. The system had never worked properly. We verified the models of the existing system and the wiring in the walls. The customer also wanted to use their I pad for playing music on the system. We discussed the replacement and settled on the new Nutone whole house intercom replacement. We also custom installed a digital Teac I pod interface into the system. This consisted of nine inside stations, a master station, and a outside station with bell button.
