The Door Com system (LDC) is a simple open voice door answering and internal All Call intercom system.
A 2-stroke chime is heard when the door station button is pressed, and can be answered from any inside
station by pressing the door "Talk" button. An internal "All Call" announcement can be made from any
inside station by holding down the "All Call" button. The chime tone can be turned off or adjusted to three
volume levels. The All Call can be muted at any station. Door release can also be included.
Up to 6 inside stations can be included in one system.
