The N-8000MI is a multisource interface for the N-8000 intercom system. When used as an analog audio bridge to the N-8000 intercom system, it accepts two line-level inputs which can be broadcast to any paging zone or station on the system. Two line-level outputs are provided, with sixteen contact closure inputs and sixteen relay outputs. Contact closures may be synchronized with a paging event, linked to contact closure inputs, be triggered by a station call, be triggered by IP control or a master station, or be triggered by a fault in the network or a 2-wire (N-8000EX/N-8010EX) line fault for 24/7 supervision. Rack mount and wall mount hardware included.
