1. Introduction

This is the installation manual for the exchange,

stations, and other components of TOA Intercom System

EXES-5000.

It includes an outline of the system, an explanation

of installation, cable connection, and inspection proce-

dures, 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

components of the system to make sure that they are in

order.

2. Introduction of the EXES-5000 System

Because the EXES-5000 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 accord-

ing to the modular concept. This results in a

sizable reduction in the number of procedures re-

quired to install the system.

2. The exchange and terminal board (BOX-064) are design-

ed as separate units, allowing independent inspec-

tion of the wiring and the exchange proper.

3. The wiring for each station is an independent 4-

wire system which uses a minimum number of connect-

ing wires and means greater ease in wiring.

2-1. Exchange

2-1-1. Feature

The features of the exchange of the TOA EXES-

5000 Intercom System are as follows:

1. All components of the exchange are designed as

plug-in modules. This results in a great in-

crease in ease and speed of system installa-

tion.

2. Extensive incorporation of ICs in the electro-

nic circuits of the exchange results in a

highly compact, space-saving design and quieter

operation than conventional intercom system.

--- 3 -

This, in turn, means greater freedom in selec-

tion of installation site.

3. Since the system is completely electronic,

power consumption is kept to a minimum, and

incorporation of a built-in batteries is also

possible.

2-1-2. Specifications

The exchange of the system is available in the

following two models.

EX-510 Capacity : 64 lines max. (56 lines

with paging function).

12 links max. (10 links

with conference function).

Dimensions: 20.6" (H) x 19.7"(W) x 12.6"(D)

(522mm) (500mm) (320mm)

Weight : 99.2 Lbs max. (45 kg. max.)

EX-520 Capacity : 128 lines max. (120 lines

with paging function).

16 links-max. (14 links

with conference function).

Dimensions: 29.3" (H) x 19.7"(W) x 12.6"(D)

(744mm) (500mm) (320mm)

Weight : 114.6 Lbs max. (52 kg. max.)

Exchange capacity can be increased within the

given limits in units of 8 lines or 4 links.

The number of links available, however, is

reduced by two when the optional conference

- 4 -

function is incorporated. The number of lines

available, on the other hand, is reduced by 8

when the paging function is adopted.

(3.5AH x 2).

2-1-3. Further Details

The component modules of the exchange are

grouped according to function as follows:

Common Control Section

CPU (Central Processing Unit)

OCU (Output Control Unit)

HCU (Highway Control Unit)

Speech Path Section

SGD (Signal Generating and Distributing Unit)

DLU (Duplex Link Unit)

CLU (Conference Link Unit)

LMU (Line Modem Unit)

PIU (Paging Interface Unit)

The individual units will be described later in

detail. The exchange also includes the power

supply unit (DS-510) and case.

The power supply unit is self-contained and can

be removed from the exchange cabinet.

The exchange usually operates on AC power.

The optional battery takes over automatically

- 6 -

in the event of a power failure. The case is

composed of a cabinet and a frame with connec-

tors

The cabinet is not needed when the exchange is

mounted on a 19" rack.

The connectors and the frame are completely

wired at the factory.

--- 7 -

CPU (Central Processing Unit)

Function: Reads out the exchange procedure

written into the memory and collates

the data from the stations for pro-

cessing in succession.

PROGRAM Switch

When functions such as secretary transfer,

master/substation and executive priority are

employed, the registration, cancellation and

changing of these functions are taken care of

through Station No.200. The PROGRAM switch is

for converting Station No.200 to Programming

station for such functions. Normally, this

Switch should be kept in the OFF position.
