SAFETY PRECAUTIONS (For N-8000EX and N-8000MI)
• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.
• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.
• After reading, keep this manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.
WARNING
CAUTION
When Installing the Unit
• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.
• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in fire or electric shock.
• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.
• Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.
When the Unit is in Use
• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.
· If you detect smoke or a strange smell coming from the unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged (exposure of the core, disconnection, etc.)
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to your nearest TOA dealer.
• Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit's cover, as this may result in fire or electric shock.
• Do not touch a plug during thunder and lightning, as this may result in electric shock.
When Installing the Unit
• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.
• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.
• Do not block the ventilation slots in the unit's cover or fan exhaust vent. Doing so may cause heat to build up inside the unit and result in fire.
CAUTION
WARNING
11
• Be sure to follow the instructions below when rack­mounting the unit. Failure to do so may cause a fire or personal injury.
· Install the equipment rack on a stable, hard floor.
Fix it with anchor bolts or take other arrangements to prevent it from falling down.
· To mount the unit on the TOA equipment rack,
use the rack mounting hardware supplied with the unit.
· When connecting the unit's power cord to an AC
outlet, use the AC outlet with current capacity allowable to the unit.
When the Unit is in Use
• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.
• Do not stand or sit on, nor hang down from the unit as this may cause it to fall down or drop, resulting in personal injury and/or property damage.

Chapter 1: GENERAL DESCRIPTION
1. GENERAL DESCRIPTION
The N-8000 Series is a packet intercom system (IP network compatible intercom) employing packet audio technology*1. By connecting IP intercom exchanges (which can connect up to 16 stations per exchange) and Multi interface units to a network (LAN or WAN), an optimal system can be constructed for in-house or wide area information communications such as duplex conversations between stations, periodical broadcasts, and BGM broadcasts. Since up to 80 exchanges and multi interface units can be combined, systems of up to a total of 1,280 stations can be realized. The system's "echo cancellation"*2feature makes hands-free duplex conversation possible (conversations made without using a handset at both parties) between stations. In addition, the multi interface unit features a contact bridge function to be performed by way of contact input and output control.
*1Technology related to audio transmission over a network. *2A circuit that prevents acoustic feedback or echo generated when the voice output from the station's
internal speaker enters the microphone.
Warning
This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.
2. FEATURES
Exchanges and Multi interface units can be distributed over a data communications network.
Can be connected to an existing local area network (LAN) or wide-area network (WAN). The system can
also be easily connected to fiber-optic networks without restrictions on operating distance.
The dedicated software program enables centralized control with a personal computer.
System maintenance (verifying operation log and Line supervision) can also be performed with a personal
computer and Internet browser.
Can be connected to the Exchange of the EXES-2000 or EXES-6000 Intercom System by a tie-line, or the PBX exchange via the OD (out-band-dialing) trunk.
The Multi interface unit can interlock with an electronic lock system or CCTV surveillance system by way of contact input/output control function.

4.2. Component Description
4.2.1. Exchange
[N-8000EX IP Intercom Exchange]
The Exchange permits connection of up to sixteen N-8000 Series stations and features two outputs for public address paging. The exchange is equipped with a networking interface, allowing connection with other IP intercom exchanges and multi interface units. The Exchange can be mounted in an EIA standard rack (1U), to a wall or installed on a desk.
4.2.2. Peripheral components
[N-8000MI Multi Interface Unit]
Having 2 channels each for audio input and output, and 16 contacts each for control input and output, the N­8000MI performs the following interface functions*.
Tie-line interface for connection with the EXES-2000 and EXES-6000 systems.
PBX interface for connection with the PBX via the OD trunk.
PA paging interface for connection with PA equipment
External input broadcast interface for connection with a music player (chime unit) or paging
microphone irrespective of with or without remote control function.
Interface to control an indicator or external equipment such as a CCTV's switcher using relay contacts.
The N-8000MI also features Network interface for connection with an IP intercom exchange or other Multi­interface unit.
* The interface functions can be combined in the following 9 patterns.
[40-Station Terminal Board E-7000TB]
The E-7000TB is a clip type terminal board for connecting station lines to each exchange. Up to 40 lines (twisted pair cables) can be connected. The optional YC-105 clipping tool is required for wiring. The E-7000TB is rack-mountable (3U size).
