(16 stations max.)
– 2 –
Central control unit CC-20:
This unit is comprised of a CPU that processes the exchange procedures, a speech link consisting of a
voice switch circuit and a signal tone generating circuit, and a power circuit.
Line modem unit LM-20:
This unit is comprised of a circuit for sending out signals from the station to the speech path, a circuit to
transmit signals from the speech link to the station, a receiver and a scanning circuit for dial data, and a
terminal block. Wires from the station are connected directly to the terminal block on the LM unit. A
maximum of 4 stations can be connected per LM unit, and up to 4 LM units can be mounted in the EX-200
and FC-210.
BGM unit BI-20:
This unit is comprised of a circuit to send out signals from BGM equipment, and alarm or time signals to
the LM unit, a circuit that transmits control signals from the alarm or timer to the CPU, and a terminal
block. The Bl unit is mounted in the exchange from the bay solely intended for this unit.
Remote control unit RC-20:
This unit is formed from relays for door remote control, power remote control and PTT control, a circuit to
activate these relays, and a terminal block. It is possible to use any bay for "option" unit to mount the
RC-20 in the exchange.
Pager control unit PC20:
This unit has the control output to remotely operate the TR-321 or TR-322 pager controller as well as the
serial data output that complies with ESPA standards. The PC-20 may be mounted in the exchange from
any bay for "option" unit.
Speech message unit SM-20:
This unit includes a circuit to convert audio signals into digital signals, a memory storing the converted
signals, and a circuit that converts digital signals into audio signals. A single SM unit has a memory
covering 4 stations, and a control circuit. A maximum of 5 SM units can be mounted in the EX-200
exchange (in this event, no room is left for mounting the RC unit, PC unit and Tl unit in the exchange), and
up to 6 in the FC-210 cabinet. However, an entire system can only accept up to 8 of the SM-20 unit.
Tie-line unit TI-20:
This unit is comprised of DTMF transmitting and receiving circuits for exchanging dial data with the other
exchange, and a circuit for transmitting voice signals.
Power transformer unit PU-200:
This unit supplies power to the EX-200 and the FC-210. Power output is 20V AC, 2.5 amperes for both
exchanges.
Extension cabinet FC-210:
This unit is employed when a system has more than 16 stations or a number of "option" units are used. A
maximum of 4 LM-20's and 6 "option" units can be mounted in the FC-210. Note that the YR-820 and
YR-821 cables are necessary for adding the LM-20 and the "option" unit, respectively.

Connection of equipment
Selection of function by No. 24 programming
Speech and performance tests
Installation of equipment
4-1 Selection of the place to install
Observe the following precautions in installing each equipment:
Allow for weight exerted on the wall when mounting the exchange on
it.
Each equipment is to be so installed as to permit easy checkup and
maintenance.
When the PA paging or talk-back function is employed, keep the
station and speaker as apart as possible from each other in order to
avoid feedback.
Do not install the exchange nor the station in the following locations:
(A) Areas where unit is exposed to heat or sunlight.
(B) Areas where metallic particles or dust are accumulated.
(C) Areas close to chemicals or oil.
(D) Areas of high moisture or near the window where unit may be
splashed by rain water.
(E) Areas close to high voltage equipment or where strong electric
field exists.

4-3 Installing FC-210 extension cabinet
Follow the procedures below to install the FC-210 cabinet:
Unscrew screws that hold the top case to a chassis at 4 places
in the sides of a cabinet.
Insert attached brackets (2 pieces) into bracket
receptacles on the bottom case of the EX-200.

Fit bracket receptacles of the FC-210 into the
brackets.
Fix the cabinet on the wall through fixing holes
provided on its bottom case.
Connect the connector CN-5 on the CC-20 card
mounted in the EX-200 to the connector CN-4 on the
printed circuit board of the FC-210 using the
attached GND connector.
Remove a rubber membrane of 2 bushings on the
bottom case of the EX-200 and FC-210 to allow the
cable entry.

(FC-210)
Note
(1) Since the YR-820 and YR-821 cables are to be used
for connecting the FC-210 to the EX-200 exchange,
there is a limit to spacing between the two units. You
should allow for this limit and fix them according to
dimensions shown at right when they are mounted
on the wall.
(2) Allow for sufficient spacing for screwing and un-
screwing the top cover when mounting on the wall.

4-5 Installation of Stations
To install stations, make connections by using station jack model YC-601 (Wall-mounted type) or YC-603
(Flush-mounted type). Since the length of station cord is 3 meters (9.8 feet), the station jack needs to be mounted
within this length.
Station jack YC-601 (Wall-mounted type)
Mount this jack on a wall, pillar or desk. Utilize either knock-out
holes provided on the top and the bottom of the case or a cable
entry hole in the base for connecting the cables to the exchange.

5. Cable installation
5-1 Cable selection
Use 2-conductor telephone or interphone cables for connection from the exchange to the station.
Be sure to use a multi-pair twisted cable such as an indoor cable and CCP-(A)P cable when the connection is
made via the external terminal board.
Select appropriate cables according to the following table that shows the relationship between cable diameter
and transmission distance.
Core diameter
0.5 mm
0.65mm
0.9 mm
Note
The figure in a parenthesis is the maximum cable length
and shown at its left is the normal service distance. The
system supplied from the factory is pre-wired for the
normal service distance. To obtain the maximum cable
length, replace the corresponding resistor R31, R39,
R51 or R59 (390k ohms) on the LM unit corresponding to
the line with that of 680k ohms. (See paragraph 6-10.)
5-2 Points to remember
The multi-pair cable used for wiring of the EXES-2000
system must not be jointly used as a power cable or
data transmitting cable for facsimile, etc.
Do not connect an unused cable to the exchange.
Do not connect an unused cable to a connection
cable between the exchange and the station.
When utilizing multi-core cables already in use for
wiring, confirm they are twisted paired cables. Unless
they are twisted cables, they may not be used due to
interference between lines.

6-1 Addition of LM unit
A basic system using the EX-200 exchange is comprised of 8
stations (2 LM units). The LM unit needs to be added according to
the following procedures when more stations are required.
(1) Establishment of the LM unit number
Set switches SW-1 and SW-2 on the LM unit to positions as
shown in the table at right according to the station numbers
connected to each LM unit. Since the LM units of a basic system
are pre-set as No. 1 and No. 2 when supplied from the factory,
the LM number has to be fixed only for the additional units.

6-4 Mounting option unit
(1) Bl unit
Insert the Bl unit into its exclusive bay and connect its connector to CN4 on the CC unit.
(2) Mounting other option units than the Bl unit
Option units other than the BI-20 are all connected to the CC unit via a common bus and so, any bay can be
used to mount them so far as it is not the one solely intended for the Bl unit. The EX-200 exchange has 5 bays
for option units, while the FC-210 has 6 bays. Insert the option units in order, stating with the bay closest to
the CC unit, and connect the connector as illustrated below.
