SYSTEM FEATURES
* Up to 90 phone stations connected in parallel by 4 twisted pairs throughout the system.
* 3 communication channels.
* Incorrect wiring causes mulfunctions of the communication channel concerned but will not affect the remaining two
communication channels.
* Complete communication privacy.
* Intercom unit designed for wall mount. YAK-A terminal box/cord is optional for desk-top use.
* Assigning station number is easily accomplished by just setting a plate on each station.
* A variety of STANDARD communication functions, such as call transfer, camp-on busy, etc. Paging and remote control
operations are available with optional accessories.
BEFORE YOU INSTALL AND OPERATE THE EQUIPMENT
Prohibitions and precautions -
* Operation;
1. DO NOT HOLD HOOK SWITCH DOWN WHILE PICKING UP HANDSET. THE CALL
TONE SOUNDS THROUGH THE HANDSET RECEIVER ELEMENT AND COULD
CAUSE HEARING DAMAGE.
NEVER
Installation;
1. DO NOT CONNECT ANY TERMINAL ON ANY UNIT TO AC POWER LINES.
2. BE SURE TO REMOVE PLUG OF POWER SUPPLY FROM AC OUTLET BEFORE
YOU OPEN THE UNIT OR MAKE WIRING CONNECTIONS.
3. Avoid running the connecting wires thorough doors, windows or between furniture,
which may pinch and disconnect the wires.
4. Installation location requirements on Page 3 must be met.

PRE-INSTALLATION INSTRUCTIONS
1. Use twisted pair cable, not straight conductors.
(1) YAZ-90-3 phone employs such components as CPU (microprocessor) and IC chips. Twisted-pair cable must be used to
prevent the unit from being interfered by line inductive noises generated by the surrounding electrical appliances and
from crosstalk and mulfunction caused by cable conductors themselves.
(2) Keep at least 30 cm (!') away from other cable, like AC power lines or paging speaker lines or telephone lines or provide
metal conduit for running cable.

Note: When locating power supplies for each block, please count the adaptors for paging or remote operation of lights as
follows;
* one YAW-R 1-zone paging adaptor as 5 YAZ-90-3 phones.
* one YAW-RA 8-zone paging adaptor as 10 YAZ-90-3 phones.
* one YAW-S remote operation adaptor as 4 YAZ-90-3 phones.
4. Installation location requirements
Do not install YAZ-90-3 phones and power supply to such places as exposed to;
1) high temperature (eg. direct sunlight, air conditioning heat, furnace, etc.)
2) low temperature (eg. refrigirated warehouse).
3) extremely high humidity.
4) water, oil, dust, chemicals, etc.
5) When the system is installed outside the building, such as ski resort and/or between buildings, etc. the cable has to be
buried under ground in metal conduit. Be sure not to run the cable in the sky which invites lightning surge and causes
permanent damage to the system.

• Be sure to assign a station number of every station installed otherwise that station would not be able to receive calls.
• Do not assign the same number to more than one station.
• Alphabets^ to]j^on the plates should remain unused.

IMPORTANT WIRING INSTRUCTIONS
(1) WIRING;
* Use twisted pair cable.
* Connect first twisted pair to terminals [T] , second twisted pair to terminals [S] , third twisted pair to ^ ^ and
forth twisted pair to[T] [J . Do not cross wires.
* Even if you have extra wires, do not use them for communication line (Do not connect two or more wires to each number
terminal).
(2) PS-24N POWER SUPPLY CONNECTION
* One PS-24N power supply is required for every 30 stations.
* Each PS-24N power supply must be located near the center of each 30 station group.
* Jp' and #-) lines must not be installed between 30 station groups, i.e. If the system includes 60 stations the first
PS-24N should be connected to station No. 25 and the second PS-24N to station No. 55. Do not connect terminals[T]
and py between stations Nos. 39 and 40.
* If you have extra wires, it may be used for wiring to [T] [)p lines (never for communication lines). It is important, how
ever, the line resistance on p] p(] lines is equal. See drawing below.
