N-8640DS IP Door Station

N-8640DS

The N-8640DS is an IP door station employing packet audio technology. Connecting the N-8640DS to an IP network (LAN or WAN) permits hands-free conversation of high sound quality to be made between the N-8640DS and the intercom station connected to the IP Intercom Exchange, or between the N-8640DS and an IP multifunctional master station. Besides, the N-8640DS can be used in conjunction with the Multi Interface units through a network. The N-8640DS 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.
