• 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

• 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.

1-2

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.

7. PAGING FUNCTION OUTLINES

There are two types of paging: (1) PA paging by way of external PA equipment and (2) Station paging by way of the station's internal speaker. Both types have access to the (1) zone paging function which pages one zone, (2) the paging function which pages multiple selected zones, and (3) the all-call paging function which pages all zones simultaneously.

7.1. Paging Types

7.1.1. PA paging

Connecting PA equipment to the exchange's or multi interface unit's output terminal permits PA paging to be made by dial operation at the station.

7.1.2. Station paging

By performing dial operation at the station, paging can be made to another station's internal speaker. Except busy stations assigned to "Conversation Priority" mode (p. 5-33). This interrupts all current conversations to allow the paging to go through, can be selected. Use the supplied N-8000 Software program to perform the mode setting.

Chapter 1: GENERAL DESCRIPTION

7.2. Paging Functions

7.2.1. Zone paging

Calls can be made to one of the pre-programmed zones. For PA paging, assign a PA paging output to the zone number. For station paging, assign a station to the zone number. One of the following three settings can be selected: PA paging only, station paging only, or a combination of PA paging and station paging. Use the supplied N-8000 Software program to perform the mode setting. There are no limitations of the number of stations that can be programmed nor the number of PA paging output.

7.2.2. Paging

By performing dial operation at the station, paging can be made to up to 10 zones of the pre-programmed multiple zones.

7.2.3. All-call paging

Calls can be made simultaneously to all of the pre-programmed zones

7.3. Station Paging Receiving Mode

The station that receives Station Paging must be set to one of the following two modes using the supplied N8000 Software program.

7.3.1. Conversation priority mode

• When a paging is made, the station in standby mode receives it. If it is engaged in conversation or dialing, it does not receive the paging.

• If paged during a conversation with another station in the same zone, the paged station receives the paging and the conversation is placed on hold. If the conversation partner belongs to a different zone, a holding tone is transmitted while the conversation is placed on hold.

Note

Dialing is possible even while receiving a paging.

7.3.2. Paging priority mode

• When a page is made, the station in standby mode receives it. If paged during a conversation, the paged station receives the page without terminating the current conversation, while a holding tone is transmitted to the conversation partner during a conversation between paging and paged parties if the paging station does not belong to the same paging zone.

• When the station being paged receives a call from another station, the paged station becomes busy and maintains the paging. When the station is paged during a conversation and the paging is still connected even after conversation completion, the paging is put through to the station.

Note

Dialing is impossible while receiving a page.

Zone 1 Zone 2 Zone 3

Chapter 1: GENERAL DESCRIPTION

7.4. Responding to Paging

If the paged party responds at the nearest station, the paging party is called and put through to the paged party. The following two response modes are available. Use the supplied N-8000 Software program to set either mode.

7.4.1. Automatic response

If the paged party dials the number assigned to paging response, the paging party who initiated the paging last is called and put through to the paged party. To use this mode, each paging zone must be independent of responding master stations assigned to each zone. When using external PA speakers, their zones must match those of master stations.

7.4.2. Zone number dialing

When making a paging, the paging party notifies the paging zone to use, and the paged party dials the designated zone number when responding. If the paged party responds dialing the designated zone number, the paging party who made the paging to the designated zone last is called and put through to the paged party. Use this mode in locations where broadcasts from multiple zones can be heard or if the Station Paging function is not used.

Step 1. Dial the number of the station to be called.

• Dialing from a master station is possible with its handset either lifted or in place.

The calling station's internal speaker sounds an audible call tone (heard in the handset speaker if the handset is lifted). When a busy tone is heard, wait till the line becomes free, and you are automatically connected to the called party.

Step 2. Conversation can begin when the calling tone stops

and the called party responds.

• When the called station is set to Automatic connection mode, the calling party is automatically connected after a brief call tone and conversation can begin.

• When the called station is set to Continuous call tone mode, a continuous call tone sounds until the called station responds, after which conversation can begin.

Step 3. When conversation is finished, press the Clear key

or replace the handset.

Note

If the system has been set for call time-out or conversation time-out, the call or conversation automatically stops after the specified time limit. The specific length of this time-out (in 10-second units between 10 and 999 seconds) is preprogrammed into individual exchanges using the supplied N-8000 software (Refer to p. 5-26).

• When a station is assigned to group call member station, if the station is called, this station (representative station) and all member stations are simultaneously called by a continuous call tone regardless of their call connection mode settings.

• Even when the representative station is busy, all of the associated member stations within the same group are called by means of a continuous call tone. This continuous call tone stops when any one of the associated stations responds to the call.

Notes

• Use the supplied N-8000 Software program to perform the group call member station setting. (Refer to p.5-38)

• The N-8050DS Door Station cannot be assigned to the group call representative station nor member station.

Call receiving modes, and call tone on/off can be selected for each station.

Use the supplied N-8000 Software program to perform the setting. (Refer to p. 5-38.)

2.3.1. Automatic connection

Incoming calls are automatically connected after a brief call tone (about 1 second) or without a call tone. When a call is received, the status indicator flashes red. It lights red continuously when a conversation begins. Lifting the handset creates a handset conversation.

2.3.2. Continuous call

Calls continue with a continuous call tone (or without a call tone) and a status indicator continuously flashes as long as no response is made. When a call is received, the status indicator flashes red. It lights red continuously when a conversation begins. Lifting the handset to respond to a call creates a handset conversation. Pressing any key to respond to a call creates a hands-free conversation (one-touch key response).

Note

The N-8050DS Door Station cannot be set for the continuous call function.

Chapter 2: FUNCTIONS AND OPERATION

2.9. Executive Priority

If a called station is busy, as indicated by a busy tone, performing Priority operation from a call station transmits a short priority call tone, then forcibly terminates the current conversation, allowing the call to go through. Access to priority call operation or refusal of priority calls can be set individually for each station. Use the supplied N-8000 Software program to perform the setting. (Refer to p.5-38)

[Operation]

When Station A calls Station B, which is at that time engaged in a conversation with Station C, Station A presses its [9] key.

A call tone is transmitted to both Stations B and C, and the conversation is forcibly terminated, enabling Station A to be connected to Station B.

• If a setting has been performed to allow Station B to refuse interrupt calls, the Priority Call function cannot be used, and the busy status remains unchanged.

2.10. Time-Out

This function restricts the duration of calling, conversation, and paging to prevent the speech path from being left unused when a user neglects to terminate conversation or paging. When the set time has elapsed, stations automatically return to standby state.

Note

Use the supplied N-8000 software to set each time limit (programmable for 10 – 990 seconds in 10-second units). (Refer to p. 5-26.)

Tip

The time limit is the duration programmed into the exchange to which the station that makes the call is connected.

2.11. Group Blocking

Stations can be blocked into groups (up to 31 groups) which can or cannot make calls to each other. Paging zone numbers available among such groups can also be set.

Note

Use the supplied N-8000 software to set the station groups, calls that can be made among groups, and paging zones that can be mutually called. (Refer to p. 5-43.)

[Group blocking group setting example]

Set arbitrary station groups (up to 31 groups).

[Setting example for enabling or disabling calls among groups]

Calls that station groups can or cannot make to each other can be freely set. In this example, Group 1 can call Groups 2 – 4 and Group 2 can call only Group 1. Groups 3 and 4 cannot call other groups.

[Setting example for paging zone numbers that can be called]

Paging zone numbers that can be called from each group can be freely set. In this example, Group 1 can make all-zone calls or page Zones 1-4, Group 2 can make all-zone calls or page only Zone 1, and Group 4 can page only Zone 4.

Note

Paging zones can be set freely regardless of group blocking group assignment. (Refer to p. 5-42.)

Chapter 2: FUNCTIONS AND OPERATION

3.2. External Input Paging (only when the N-8000MI is used)

Activating the control input after connecting the Remote microphone or playback components to the Multi interface unit enables broadcasting to the preprogrammed zone(s). There are two methods of activation: one is to use the Audio input terminal (A in the following figure), and the other is to use the Contact input terminal (B). Set only the broadcast zones when activating the Audio input terminal, and both the broadcast zones and input sound source when activating the Contact input terminal. Set the input sound source operation mode to "External input paging."

Note

Use the supplied N-8000 software to perform each setting. (Refer to p. 5-34, p. 5-36.)

• Closing the control input terminal broadcasts the outputs from the external sound source to the preprogrammed paging zone(s).

• The broadcast ends when the control input terminal opens.

In this example, a sound source is broadcast to Paging Zone 1 by activating the Audio input terminal and to Paging Zone 23 by activating the Control input terminal. Both broadcasts will not coincide. While a broadcast is being made to Paging Zone 1, another broadcast by the Control input terminal activation is neglected.

[Priority]

• There is no priority between control signals coming to the Audio input terminal and the Contact input terminal. Even if either terminal is closed while the other terminal is closed, the later activation is not accepted.

• Priorities are equal between paging calls, whether they are initiated by the N-8000 system station or other system station. If one input terminal closes while the other terminal is closed for paging, the last paging is placed in standby mode, and is allowed to go through when the other paging is completed.

3.3. Responding to Paging

If the paged party responds at the nearest station, the paging party is called and put through to the paged party. "Automatic Response" and "Zone Number Designation Response" modes are available, and the system is preset to one of the two paging response modes. (Refer to p. 5-26.)

3.3.1. Automatic response

If the paged party responds dialing the Paging Response key, the paging party who made the last page is called and put through to the paged party.

[Operation]

If the paged party presses the Paging Response key, the paging party who made the last page is called and put through to the paged party.

• Since each paging zone is independent, responding from any station where a paging is audible connects the

paged party to the paging party.

INSTALLATION & WIRING

This chapter describes installation and wiring procedures, including the installation and connection of the Exchange, Multi interface unit, and stations.

3-2

Chapter 3: INSTALLATION & WIRING

1. INSTALLATION OF THE EXCHANGE

The Exchange can be installed in any of three ways: (1) equipment rack mounting, (2) wall mounting, and (3) desk-top installation.

1.1. Equipment Rack Mounting

A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient

temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow

required for safe operation of the equipment is not compromised.

C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is

not achieved due to uneven mechanical loading.

D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit

and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention

should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips)."

The Exchange can be mounted on the CR-273 or CR-413 or standard EIA 19" Equipment rack. One CR-273 for up to 128 stations, one CR-413 for up to 192 stations and seven CR-413 for up to a total of 1280 stations can be connected. For the CR-273 and CR-413 Equipment rack assembly or BU-412 Blower unit installation, read the installation manual supplied with the rack.

Note

When installing the Blower units, Terminal boards, and Exchanges, lay the equipment rack down face-up to do installation work safely. Since the Blower unit is installed from the inside of the rack, be sure to install it first, before mounting the other components.

1.1.1. Setting space

For maintenance works, allow much space between the wall and Equipment rack.

CAUTION

Do not block the fan exhaust vent. Doing so may cause heat to build up inside the unit and result in fire.

1.1.2. Caution when installing the unit

Do not stack up 3 Exchanges or more. If 2 or more Exchanges are mounted in the Equipment rack, be sure to mount the perforated panel of 1-unit size (PF-013B) or more above and below every 2 Exchanges.

Using the supplied rack mounting screws, install the terminal board in a location that facilitates wiring and maintenance work, taking into consideration the direction of cable entry into the rack.
