The TOA N-8000EX IP Intercom Exchange Unit for RS-1 Series makes use of packet audio technology, enabling the connection of up to 16 N-8000 series 2-wire master or door stations. Both the master and door stations are wired with the same unshielded twisted pair. Each N-8000EX can support up to 8 external voice links and 4 internal voice links, offering features such as the audio trigger function, two balanced line-level analog audio output channels, and two relay outputs. This exchange can function independently (with a minimum of one master station) or be integrated into an N-8000 IP intercom system through LAN or WAN.
