communication system, voice access, electric door release, aiphone intercom system The Door Com System(LDC) is a simple open voice door answering and internal All Call intercom system. The LDC-S/A multi-door capable open voice access control kit includes (1) door station, (3) master stations with door release button and (1) power supply. The LDC-S/A is great for any residence or business and up to 6 inside stations can be used with the LDC-S/A system.

Communication is done via a general page (or all-call) throughout the system. This means you cannot selectively call a particular station from another. Any of the 6 indoor stations can communicate with the door station. 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. Listen to the door station area from any inside station. Speak to all inside stations simultaneously. Activate electric door release, or open or close a garage door from any inside station. The chime tone can be turned off or adjusted to three volume levels. The All Call can be muted at any station, which will cut-off the station from receiving the all-call page, ideal in the study or baby's room. The all-weather door station has a built-in doorbell button, which is backlit for ease of use at night. The LDC-S uses easy common wiring and is simple to use.
