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)
Audio Input Level : +10dBm max.

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.
