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.

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.
- 8 -

OCU (Output Control Unit)
Function: temporary storage before usage of
the output data from CPU classified
by lines.
SCN SELECT Lamp
These lamps display the scanning conditions of
both the station "Privacy ON/OFF" conditions
and the dial data from the station in each LMU.
--- 9 -

HCU (HIGHWAY CONTROL UNIT)
Function: For turning on and off the time-
sharing switches at LMU, DLU and SGD
according to instructions received
from the CPU.
LINE ADDRESS Lamp
These lamps dispaly the numbers of the stations
using the selected link (T: Transmitting station,
R: Receiving station)
SIGNAL CODE Lamp
These lamps display the code of signal tone
being used by the selected link.
SIGNAL CODE TONE
0 Calling
1 Privacy/Disconnected
2 Busy
3 Dialing/No-registration
4 Group paging/Zone paging
5 All call
6 Priority/Executive priority
7 Registration/Call holding/Mic-off
--- 10 -

LINK SELECT Switch
The switch position is to be selected in accor-
dance with the number of links in use. The line
address and the signal code of the link in use
are then displayed by the lamps.
Note: These select switches are to be manipu-
lated using the binary notation.
LINK BUSY Lamp
These lamps display the number of the link in
use.
CLOCK Lamp
Indicates that the control signal for the time
sharing switch is being transmitted normally.
--- 11 -

DLU (DUPLEX LINK UNIT)
Function: This unit operates under HCU control
to connect or disconnect the in-
dividual links for hands free con-
versation between two stations.
One DLU is provided with 4 links.
Up to 3 DLUs can be installed with
the EX-510, and up to 4 DLUs with
the EX-520.
----- 12 -

SGD (SIGNAL GENERATING AND DISTRIBUTING UNIT)
Function: Composed of 8 kinds of signal
generators (calling, privacy/dis-
connected, busy dialing/no-regist-
ration, group paging/zone paging, all
call, priority/execution priority,
registration/call holding/mic-off)
and distributors.
This unit distributes under HCU
control the required signal tones to
the individual links.

Function: This unit operates under HCU control
to connect or disconnect the links
for hands-free conference among up
to 4 parties and hands-free speech
between two parties.
One CLU is provided with 1 conference
link and 2 hands-free speech links.
The CLU is optionally available.

LMU (LINE MODEM UNIT)
This unit is composed of a modulator to receive
signals from the station, a demodulator to send
out signals to the station and a scanning circuit
that scans the station "Privacy ON/OFF" condi-
tions and the dial data.
Up to 8 stations can be connected to 1 LMU.
Station No. Lamp
Of the numbered lamps, the one corresponding
to a given station is lit brightly or dimly to
reflect the condition of the station.
Bright : Exchange and station are connected
and the privacy switch is off.
(It is not known whether the station
is busy or not)
Dim : Exchange and station are connected,
with the privacy switch on.
----- 16 -

Off : Exchange and station are not con-
nected.
Arrangement of the LMUs with individual ranges
for the station numbers covered (from left to
right) is shown here.
----- 17 -

PIU (PAGING INTERFACE UNIT)
Function: This unit is provided for zone pag-
ing and group paging. It is design-
ed to send out over the lines both
zone and group paging signals.
The zone paging signal goes out
through the assigned YR-801 cable to
terminal J8 or J16 of the Terminal board
(BOX-064), while the group paging
signal is distributed to the connec-
tor of the PIU unit.
This unit can control up to 7 areas
(zones and/or groups) plus All-Call.
All-Call and Individual (Zone/Group) Paging Lamp
These lamps display the areas being paged as
well as All-Call paging conditions. All-Call
paging is displayed when all of the lamps are
lit.
