MODEL: YAZ-90-3 (wall mount)

- INSTRUCTIONS -

YAZ-90-3 is a microprocessor-based intercom, requiring no central exchange unit and with a maximum capability of

90 stations installed per system.

Wiring is accomplished by running 4 twisted pairs in parallel throughout the system, which facilitates ease in installation,

changing location and system expansion.

Various communication functions are standard and the YAZ system is ideal for use in schools, hospitals, offices, public

institutions, factories, banks etc.

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.

Maintenance;

1. Clean your intercom equipment with a soft cloth dampened with neutral household cleanser. Never use thinner nor benzine, etc.

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.
