INTRODUCTION TO THE INSTALLATION MANUAL FOR EXES-6000
This manual forms part of the Installation Manual for INTERCOM SYSTEM EXES-6000.
The EXES-6000 permits various functions besides normal speech by programming or con-
necting optional equipment according to your specific needs. Correct operation of these
additional functions is not performed by simply connecting the additional equipments/
devices. Provision of such additional function requires the following:
(1) Connection of the additional equipment, as required.
(2) Selection of functions which satisfy your needs and setting up these functions in the
respective equipment.
This "Installation Handbook of Exchanges EX-610/620/630 for EXES-6000 System"
contains technical instructions as to connection of exchange, etc, mentioned in the above
Paragraph (1). In addition to this, the proper installation of the system necessitates the

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 of connecting to ease wiring.
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.
1-2 Exchanges EX-610 (64 stations)/EX-620 (128
stations)/EX-630 (256 stations)
The features of the exchange of the Toa EXES-6000 Intercom
Systemareasfollows:
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 conven-
tional intercom system.
1-5 Junction Cables (YR-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-810)
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.
1-3 Stations
The stations of the Toa Intercom EXES-6000 have the following
features:
1. Each station is provided with a 2-Pin plug (YC-602) for easy
connection to cables.
2. Wiring from the exchange to each station is the non-polar 2-wire
system. The fact that only 2 wires are necessary makes installa-
tion 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 screw-
driver.
3. There are eleven types of stations available for selection: desk-
top type, flush-mount type and desk/surface-mount type, etc.

PART2. INSTALLATION OF EXES-6000 SYSTEM
6. Installation of the EXES-6000 System
6-1 Exchanges
Pay particular attention to the following points during installation
of the exchange:
The layout should allow easy servicing and inspection.
The exchange is compact and lightweight; however it is impor-
tant 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 combina-
tion 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 for the 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 sufficient.
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.
6-2 Stations
Particular attention should be given to the following points during
installation.
Choose a desk-top type, flush-mount type or desk/surface
mount type 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. How-
ever, 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.
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 con-
nected with a reasonable amount of slack in it.
– 9 –

7. Cable Installation
7-1 The Type of Cables
Wire type, number of wire pairs and number of individual wires are
to be determined for individual sections of the wiring system ac-
cording 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 for wiring between
indoor terminal boards, intermediate terminal boards, main
terminal boards, etc.
Indoors, the number of cables that can be run through a conduit
is, as a rule, less than 200 pairs.
Outdoor wires should be used where wiring passes through inac-
cessible areas such as in ceilings or under floors. Indoor wires may
also be used, however, in cases where there is no risk of deteriora-
tion due to exposure to heat, etc.
The number of cable pairs laid should be determined considering
the possibility of future expansion of the system.
The following chart is provided to give an actual example of the
wiring plan within an installed system.

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 diam-
eter 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 exten-
sion 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.

3. Piping
Where wiring is to be passed through a wall or the like, it should
be protected by a hard PVC 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 will 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 floor duct if the number of connecting wires is large and the
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:
Wall
Metal or hard PVC tube
2-Pin Jack
& Plug
Wire
protector
Box
Desk

Floor duct
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 through 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.

Remarks
This minimum spacing
requirement should be
observed, since intercom
cable is vulnerable
to heat.
More spacing is required
where there is a risk of
induction.
