Product DescriptionThe directory card is used to label the call buttons on a compatible intercom master station so users can easily identify which button corresponds to each room or location. It fits neatly into the designated slot on the front of the unit and provides a clean space for writing names, numbers or descriptions. The card helps keep the intercom system organized, especially in buildings with multiple stations, and makes it easy to update information when occupants or room assignments change. It is a practical accessory that maintains a tidy and professional appearance while supporting clear and efficient communication for residential, commercial or institutional installations.
