1. Introduction
This is the installation manual for the exchange,
stations, and other components of TOA Intercom System
EXES-1000.
It includes an outline of the system, an explanation
of installation, cable connection, and inspection pro-
cedures, and a trouble-shooting guide. Careful study of
this manual is recommended prior to installation of the
system.
This manual is only intended to give the information
necessary for proper installation of the system.
Prior to installation of the system, unpack the com-
ponents of the system to make sure that they are in order.

2. Introduction of the EXES-1000 System
Because the EXES-1000 System is a fully electronic intercom
system, it has the following features that surpass con-
ventional mechanical systems:
1. All components of the exchange are designed according
to the modular concept. This results in a sizable re-
duction in the number of procedures required to install
the system.
2. The exchange is a wall-mounted type for space conser-
vation. The exchange and terminal board module are
designed as separate units so that installation only
involves securing of the terminal board to a wall and
attachment of the exchange to the terminal board,
3. The wiring for each station is an independent 4-wire
system which uses a minimum number of connecting wires
and means greater ease in wiring.
2-1. Exchange
2-1-1. Features
The features of the exchange of the TOA EXES-1000
Intercom System are as follows:
1. All components of the exchange are designed
as plug-in modules. This results in a great
increase in ease and speed of system instal-
lation.
2. Extensive incorporation of ICs in the elec-
tronic circuits of the exchange results in a
- 4 -

highly compact, space-saving design and
quieter operation than conventional intercom
system.
The system consists of only three types of
basic units. This, in turn, means greater
freedom in selection of an installation site.
3. Since the system is completely electronic,
power consumption is kept to a minimum.
2-1-2. Specifications
The exchange of the system is available with the
following specifications:
EX-110 Capacity: 32 lines max. (31 lines with
paging function).
4 links
Dimensions : 19.1"(H) x 15.8"(W) x 7.0"(D)
(486mm) (400mm) (180mm)
Weight : 49 lbs max.(22 kg max.)
Exchange capacity can be increased within the
given limits in units of 8 lines.
The number of lines available is reduced by 1
when the paging function is adopted.
Exchange Specifications
Ambient Temperature Range
: 32° - 122°F (0° - 50°C)

2-1-3. Further Details
The component modules of the exchange are grouped
according to function as follows:
Common Control Section
CCU (Central Control Unit)
Speech Path Section
DLU (Duplex Link Unit)
LMU (Line Modem Unit)
The individual units will be described later in
detail. The exchange also includes the Frame &
Cabinet (FC-11). The Frame and Cabinet includes
a power supply module (DSM-11) and terminal
board module (TBM-11).

The power supply unit is self-contained and can
be removed from the exchange cabinet.
The exchange operates on AC power.
The exchange is a compact, wall-mounted type.
The connectors and the frame are completely wired
at the factory.
CCU (Central Control Unit)
The Central Control Unit is composed of the
following three sections:
a) Central Processing Section
Controls ROM for the exchange procedure and
RAM for the data in the memory, as well as
performing transmission of input/output data
between exchange and station.
b) Input/Output Control Section
Systematically classifies output data from
Central Processing Section and then, after
temporary storage, transmits the data.
It also receives dial data from station(s)
for Central Processing Section.

c) Highway Switch Control Section
Directed by the Central Processing Section,
connects and disconnects the time-sharing
switches of station selection, link selection
and signal tone selection provided by LMU and
DLU.

DLU (Duplex Link Unit)
The Duplex Link Unit is made up of the following
two sections:
a) Duplex Link Section
Operates under CCU control to make for inde-
pendent hands-free conversation between two
stations. It is equipped with connection
circuitry for 4 links.
b) Signal Generating and Distributing Section
Composed of a 4 tone signal generator [Call
(All Call Paging), Line Busy, Hold and
Privacy] and a distributor controlled by CCU
which transmits the necessary signal tone to
the line.

LMU (Line Modem Unit)
This is an interface unit for connecting
stations and exchange and performs the follow-
ing two functions:
a) Line Scanner Section
Scans the station "Privacy ON/OFF" conditions
and the dial data of the station and also
transmits data to the CCU.
b) Line Modem Section
Modulates the audio signal from a station and
transmits the modulated signal to DLU through
Highway T also demodulates the signal from
DLU through Highway R and transmits the de-
modulated signal to the station. Up to 8-
station can be connected to one LMU.

The Frame and Cabinet consists of the following
modules:
a) Power Supply Module (DSM-11)
The power supply is especially designed for
the exchange EX-110 and is housed in the
cabinet. Connections must be done as shown
in the photograph.

b) Terminal Board Module (TBM-11)
The Terminal Board Module is designed to be
separated from the exchange and is wall-mounted
for space conservation. It is provided with an
AC input terminal and terminals for 32 stations.
The clip terminals make soldering or screws
unnecessary.

2-1-4. Installation of each unit (CCU, DLU, LMU)
The card rack containes each unit is fixed with
the fitting metal. The location of these unit
is clearly marked on the card rack.
Remove the fitting metal. Pull out connection
plugs from LMU's and pull a top part of the
card rack toward you, then plugging in or out
LMU's. No connection cable is required for CCU
and DLU.
To increase the LMU, pull out the connection
cable from the cable pocket to make the complete
connection of the LMU which is additionally
plugged in.
Finally, please double check if the LMU's are
plugged in the proper location.

2-2. Stations
2-2-1. Features
The stations of the Toa Intercom EXES-1000 have
the following features:
1. Each station is provided with a 4-Pin plug
(YC-102) for easy connection to cables.
2. Wiring from the exchange to each station is
the independent 4-wire system. The fact that
only 4 wires are necessary makes installation
easier, and with a 4-Pin jack (YC-101 or YC-103)
at the end of each cable, connection can be
quickly made with a screwdriver.
There are three types of stations available
the desk-top type, the flush mounting type
and desk/wall type. Each type is available
in 2 models, both master and substation, and
these can be chosen in accordance with re-
quirements.
