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.

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.
