PART1. OUTLINES OF EXES-6000 SYSTEM AND RELATED EQUIPMENT

1. Description and Features

1-1 System

Since the EXES-6000 System is a fully electronic intercom

system, it has the following features that surpass conventional

mechanical systems.

1. All components of the exchange are designed according to the

modular concept. This results in a sizable reduction in the number of procedures required to install the system.

2. The exchange and terminal boards (BX-610/620) are designed as separate units, allowing independent inspection of the wiring and the exchange.

3. The wiring for each station is a non-polar 2-wire system which uses a minimum

number

connecting

ease

wiring.

1-2 Exchanges EX-610 (64 stations)/EX-620 (128

stations)/EX-630 (256 stations)

The features of the exchange of the Toa EXES-6000 Intercom

Syste m are as follows:

1. All exchange are of modulor constructions. This results in a great increase in ease and speed of system installation.

2. Extensive incorporation of ICs makes each exchange efficient and space-saving as well as allows quieter operation than conventional intercom system.

1-3 Stations

The stations of the Toa Intercom EXES-6000 have the following features:

Each

station

connection to cables.

provided

2. Wiring from the exchange to each station is the non-polar 2-wire

system. The fact that only 2 wires are necessary makes installation easier, and with a 2-Pin jack (YC-601 or YC-603) at the end of each cable, connection can be quickly made with a screwdriver.

3. There are eleven types of stations available for selection: desk-

top type, flush-mount type and desk/surface-mount type, etc.

1-4 Terminal Boards (BX-610/620)

The terminal boards BX-610/620 connect the line between the exchange and the station. Compact and easy to connect, this

terminal board saves space and ensures simple disconnection of any

station line from the exchange when inspection is necessary. One

terminal board BX-610 or BX-620 can connect a maximum of 64 stations (EX-610) or 128 stations (EX-620) to the exchange all-call plus 15 paging zones and 8 tie-line links. The exchange and the

terminal board are connected by junction cable YR-810 (2-wire)

for stations and YR-801 (4-wire) for paging and tie-line links.

To connect the station line to the terminal board, clip terminals are

provided which allow ensure simple connection without soldering.

For future system expansion or modification, the collective terminal

board to be described later on. (See page 12) This terminal is part of

the exchange.

1-5 Junction Cables ( Y R -810/801)

The YR-810 or YR-801 junction cable connects the exchange to the terminal board BX-610 or BX-620. A single line of this junction cable is capable of connecting the exchange to 8 stations (YR-81 0) or to 8 paging zones (YR-801) or to 8 tie-line links (YR-801) through the terminal board BX-610 or BX-620. Both cable ends are

equipped with multi-pole connectors which can easily plugged into

the exchange or the terminal board BX-610 or 620. Refer to the

drawing which appears in the Cable Installation and Connection

seciton of this manual for the right direction and order of cable connections.

PART2. INSTALLATION OF EXES-6000 SYSTEM

6. Installation of the EXES-6000 System

6-1 Exchanges

Pay particular attention to the following points du ring installation

of the exchange:

The layout should allow easy servicing and inspection. The exchange is compact and lightweight; however it is important to ascertain the strength of the floor or wall on which it will be placed. The exchange should be grounded. When it is used in combination with other systems, for example, a PA system, the exchange should be connected to the other components for common grounding. Choose a low "source noise" AC power supply f or th e exchange. Line noise can downgrade speech quality. Be sure to provide a power outlet for the exchange and have its

capacity checked. A capacity of 500 watts is su fficient.

Plan the layout so that the terminal board BX-610 or BX-620 can be installed near the exchange.

System should include a surge protector.

This high performance exchange is compact as well as quiet, and can be easily installed almost anywhere. Areas described below, however, should be strictly avoided.

An area where it will obstruct traffic, for example, an indoor hallway or near the entrance or exit of a room. An area where it will be exposed to fire, heat or direct sunlight (suitable ambient temperature is 0° ~ +40°C (+32° ~ +104°F)). A dusty area (where there is metal dust or dirt). Near a storage place for chemicals, oil, etc. An area susceptible to vibration. Near high-voltage equipment. In a strong electric field. Near equipment vulnerable to the influence of an electric field.

6-3 Accessories

The terminal board BX-610 or BX-620, which is to be connected to the exchange by junction cable YR-810 or YR-801, can be mounted

on a wall near the exchange if the cable length 2.5m (8.2 feets) and cable routing is adequate. The exchange should also be installed so that it can easily be connected to the station line.

Junction cable YR-810 or YR-801, which connects the exchange

and the terminal board, should not be bent at a sharp angle. The terminal board should be installed so that the cable can be connected with a reasonable amount of slack in it.

6-2 Stations

Particular attention should be given to the following points during

installation.

Choose a desk-top type, flush-mount type or desk/surface

mount typ e station according to the user's need.

If the PA paging function is adopted, precautions should be taken to ensure against feed-back due to interference between the station (microphone) and the paging speaker; that is, they should be installed facing different directions or separated from each other as far as possible. The "para-branching" operation or the connection of more than

one station to one circuit is not possible.

Stations are compact for each installation almost anywhere. However, areas described below should be strictly avoided.

An area where it can be exposed to fire, heat or direct sunlight

(suitable ambient temperature is 0° ~ +60° C (+32° ~ +140°F)

(except HF-640S) or -10° ~ +60°C (+14° ~ +140°F) (Door

Station HF-640S)).

A dusty area (where there is metal dust or dirt). Near a storage place for chemicals, oil, etc.

An area subject to vibration.

Near high-voltage equipment.

In a strong electric field.

SCR type light dimmers.

7. Cable Installation

7-1 The Ty pe of Cables

Wire type, number of wi re pairs and number of individual wires are to be determined for individual sections of the wiring system according to the guidelines set out below.

Twisted paired cables (such as those used for key telephones)

are to be used for wiring between the station and the intermediate

or indoor terminal board. As a rule, private branch cables are to be used f or wiring between indoor terminal boards, intermediate terminal boards, main

terminal boards, e tc.

4. 2-Wire Cable Never use a cable of 4 cores or more which is not paired or quad-paired for connection to stations.

Note: Since hardware to connect the cable to the terminal board BX-610 or BX-620 is

provided, there is a limit to the diameter of cables that can be used to connect the terminal board BX-610 or BX-620 and the main terminal board, and this limit must be taken into consideration when planning wiring of the system. The diameter must be between 0.41mm (0.016") and 0.79mm (0.031").

7-3 Wiring

1. General Information

Wiring should be done independently of public telephone lines. Otherwise the EXES-6000's line (+30 dBm) can cause cross-talk in

the telephone line.

Wiring conduit is often installed underground or embedded in

building structures such as walls and floors, so care must be taken to draw up a wiring plan that has ample reserve for future extension of the system and that can be adapted to future remodelling

or expansion of the building it is housed in. Wiring systems must be planned with ample wires and conduit and with provision for

additions to the system.

Do not connect an unused cable to a connection cable between

the exchange and the station.

Station

3. Piping

Where wiring is to be passed through a wall or the like, it should be protected by a hard P VC or metal tube.

If the number of connecting wires between an indoor terminal

board and a station is small and the station's site is fixed so that

it wil l not be moved frequently, install a box at that site and pull

wiring through a metal or hard PVC tube as required by job or

ordinance.

Use a fl o o r duct if the number of connecting wires is large and th e

stations are likely to be moved frequently. Station wiring which must be laid-across open areas of floor should be protected by plastic or metal shields. (See drawing

below)

EXAMPLE:

Not allowed

When a multi-pair cable is used for connection, it must not be used

as a power cable or data transmitting cable for facsimile, etc.

2. Spacing

Since the working voltage of this system is low and the current

passing throug h it is small, there is no major safety problem involved

in the wiring. However, since interference due to contact with other indoor wiring

can cause wire damage, leakage, and other problems, spacing should be given close consideration when the small-current wiring of this

system is laid close to other indoor wiring, particularly AC wiring.

The following chart lists spacing standards to be followed in respect to typical causes of interference.

9. Connection and Adjustment of Equipment

9-1 Connection of the Speaker Station (Simplified Paging)

In the EXES-6000, instead of using a station, a speaker for one-way conversa tion can be installed using a jumper in the LM-62B. This is possible at each station position on th e LM-62B.

1. Cutting off the jumper wires of the LM units.

Cut off the jumper wires (JP101-

JP801) corresponding to the line con-

nected for "Speaker station" function.

<For the LM-62B/LM-62C/LM-65/

LM-65C units>

Cut off the jumper wires (JP104JP804) corresponding to the line connected for "Speaker station" function.

2. Speaker Volume Adjustment

1. Speakers with an impedance of 600 ohms or more may be

used without a transformer. If it is desired to use lower impedance speakers, a transformer

should be used to assure proper impedance matching.

2. Volume may be controlled only when:

(a) a matching transformer is used.

9- 4 Precautions in using conference unit

The Conference Unit CL-62A is required for holding the interco m conference. Build this unit in all exchanges connected by tie-line. It is not possible to orginate the conference from a station connected to the exchange without the CL unit but possible to participate in the conference from that station.

9-5 Indication and control

Use the DT-E60 data transmitting unit or the DR-B61 data receiving unit for indication and control.

DT-E60: One (1) DT-E60 unit can be mounted in the rack type

DR-B61: Such devices as indicator, control unit etc. can be made

exchange. Use the YR-806 cable (1000 mm in length).

When using 2 or more DT-E60 units, mount the m in an

equipment rack. Use the YR-802 cable (400 mm in length) for connection between the exchange and the DT-E60, and the YR-803 extension cable f o r the DT-E60.

9-6 Connecting the station f or emergency paging

Connect the station to pin No.247 (147). An emergency paging call can be placed by lifting a handset of the handset type station

or by shifting back the Privacy switch of the handsfree station from

ON to

OFF.

9-7 Press-to-talk control

The PI -62 paging interface is required.

1. Be sure to use the PI-62 T ype 2, a modified version of Type 1.

2. Insert the Type 2 into the PI2 slot (Z one No.8 ~ No.15) when the EX-610 or EX-620 exchange is used, and into the PI4 slot

(Zone No.24 ~ No.31) when the EX-630 exchange is used.

3. Call the station No.200 (No.100) ~ No.207 (No.107). Pressing the PTT bar causes the relay corresponding to No.0 to No.7 of the PI unit to be connected, and releasing it disconnects the relay.

4. The press-to-talk control function can be used for door lock release, switch control of signal transmission/reception to and

from radio equipment via an interface, etc.

The BGM volume of each individual station may be decreased by cutting off the corresponding jumper wires (JP103-JP803, JP102-JP802). See the figure below.

1. Cutting off the jumper wire having the greatest number of the two (JP103-JP803) decreases the volume by 6

dB.

2. Cutting o ff the both of the paired jumper wires (JP103JP803, JP102-JP802) decreases the volume by 12 d B.

10. Preformance test 10-1 Check when Power is Switched On

Before turning on the power switch, check if the power cord is plugged in and th e fuse is in place. Also, check for damage to the printed circuit board, connectors a n d power section. Make sure that the connections of exchange and stations are co mpleted. Turn on the Power switch o f th e exchange. The front-mounted AC indicator of the exchange comes on. If it does not come on, set the power switch to OFF and check both the cor d a n d fuse. Connect batteries after confirming that the system operates on AC mains. Use 2 batteries for the EX-610 and 3 batteries for the EX-620/ 630: voltage; 24V, capacity; 3.5 Ah per battery for EX-610/620, 6A per battery for EX-630. With batteries connected, system unit automatically switches to battery operation when AC power source is cut off . In the event of the

DS-610, DC indicator lamp will be on being accompanied by buzzer. To stop the buzzer, push the buzzer reset switch.

In the event of the DS-620/630, an operation indicator lamp changes from green to red.

10-2 Speech and Function Tests

After completion of wiring, exchange checks and power supplying, perform operation and function tests from each station. Record the test

results

"Initial

Checking

1. Speech Te st

Under the normal condition, make conversation using the stations connected to the exchange and check the sound volume and sound quality. According to the operation environment (surrounding noise,

echo, installed location, etc.), the microphone sensitivity or

speaker volume needs to be adjusted for hands-free conversation.

When the paging function is employed, adjust the gain of the

paging amplifier or change the installed location of the speakers

and stations to minimize f eed-back.

at station A is high.

(Voice from station B is almost impossible to hear.)

(1) Hands-free conversation

1. Call the other station.

2. Start conversation about 50 cm away fr o m each s ta tio n to check the sound quality and its volume.

3. Confirm that the automatic voice switching allows for smooth conversation.

4. When the other station is in a very noisy area, the voice switches are liable to fail to work properly, causing the voic e from the station in a quiet area to be interrupted. In this case, adjust microphone sensitivity and speaker sound volume according to the operating instructions contained in a package of each s ta tio n.

(2) Conversation between a handset station and handsfree station

1. Call the other station.

2. Start conversation and check the sound quality and sound volume. Also confirm that simu lt aneous conversation is possible.

3. When feedback occurs, adjust the microphone sensitivity or speaker volume of t he hands-free station.

(3) Handset conversation
