The N-8000AF provides either an analog audio input/output bridge to the N-8000 system, a bell schedule generator with internal tones, or record functionality for archival purposes. It can also function as the system master clock, with sync to contact closure or NTP server as required. When used as an analog audio bridge to the N-8000 intercom system, it accepts one mic or line level input which can be broadcast to any paging zone or station on the system. One line-level output is provided, with eight contact closure inputs and eight contact closure outputs. Contact closures may be synchronized with a paging event. When used as a bell schedule generator, the N-8000AF provides 16 schedules with 64 events per schedule. Five internal tones are available, with the option to trigger up to four external paging sources. When used as for recording it provides an analog audio output and contact closure control for external recording devices to record pages, announcements, and conversations.
