You can talk directly with visitors using integrated technology. Even open a locked door right from your Norstar telephone. It's the secure, easy-to-use answer you need to manage traffic. When a visitor presses the Call button on your Doorphone, the Norstar system rings the designated phone or phones in your office. Your Norstar telephone displays which Doorphone is calling. You can then greet your visitors over the intercom. And with the optional Door Opening Controller (DOC), any Norstar telephone can control a latch on a door or a gate. Simply press the softkey below OPEN in your LCD Window. And the door opens.
 
The Norstar Doorphone, available in brass or stainless steel faceplates, is a snap to install. Up to four Doorphones can be added to your Norstar.
