The TOA N-8000MI Multisource Interface for N-8000Intercom System serves as an analog audio bridge. It can accept twoline-level inputs that can be distributed to any paging zone or station withinthe system. Moreover, it is equipped with two line-level outputs, sixteencontact closure inputs, and sixteen relay outputs. These contact closures canbe synchronized with paging events, linked to contact closure inputs, triggeredby a station call, controlled via IP or a master station, or prompted by anetwork fault or a 2-wire (N-8000EX/N-8010EX) line fault for continuous monitoring.The package includes both rack mount and wall mount hardware.
Key Features
- The N-8000MI serves as a versatile interface for the N-8000intercom system.
- It functions as an analog audio bridge, allowing twoline-level inputs to be broadcasted to any paging zone or station within thesystem.
- The interface provides two line-level outputs, along withsixteen contact closure inputs and sixteen relay outputs.
- Contact closures can be synchronized with paging events,linked to contact closure inputs, triggered by station calls, IP control,master stations, network faults, or 2-wire line faults for continuoussupervision.
- The N-8000MI comes with both rack mount and wall mounthardware for easy installation.
- It features a 10/100BaseTX Ethernet network connection forseamless connectivity.
- The interface occupies one network node, with a maximum of192 nodes supported.
- It includes a contact bridge, enabling smooth communicationbetween different components of the intercom system.
- The N-8000MI offers sixteen contact inputs, allowing forvarious input sources to be integrated into the system.
- Additionally, it provides sixteen relay outputs forcontrolling external devices or triggering specific actions within the intercomsystem.
