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 rack-
mounting 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.

GENERAL DESCRIPTION
This chapter describes the Exchange and Multi interface unit system configurations,
station types, and functions of the N-8000 Series Packet Intercom System.

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 N-
8000MI 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 Multi-
interface unit.
* The interface functions can be combined in the following 9 patterns.
