The N-8650DS is an IP door station for indoor use, employing packet audio technology. Connecting the N-8650DS to an IP network (LAN or WAN) permits hands-free conversation of high sound quality to be made between the N-8650DS and the intercom station connected to the IP Intercom Exchange, or between the N-8650DS and an IP multifunctional master station. The N-8650DS can also be used in conjunction with the Multi Interface units through a network. It is equipped with 1 channel of control input, 5 channels of control outputs (including 1 channel of relay control output), and speaker output, thereby enabling connections of external equipment such as a sensor, indicator, and external speaker.
