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

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.
