N-8000EX

The N-8000EX IP Intercom Exchange uses packet audio technology to permit connection of up to 16 N-8000 series 2-wire master or door stations. Master stations and door stations use the same unshielded twisted pair wiring. Each N-8000EX supports up to 8 external voice links and 4 internal voice links. The N-8000EX supports the audio trigger function. The N-8000EX includes two balanced line level analog audio output channels and two relay outputs. The exchange may be used as a stand-alone system (requires at least one master station) or connected to an N-8000 IP intercom system over LAN or WAN.
