The Norstar Doorphone is a digital two-way intercom that allows a Norstar telephone user inside a building to monitor and communicate with visitors outside the building. Also, when used with the Door Opening Controller (optional), the user can allow visitors access to the building remotely by pressing a soft key on the telephone set. The Norstar Doorphone uses a station port, eliminating the need for additional lines. This model comes with a stainless steel or brass faceplate.
