4. Do not put any metal into the unit though the openings./^
Fire or electric shock or unit trouble could result.

5. Do not plug or unplug with wet hands. /O
Electric shock could result.

6. Do not use DC power supply with a voltage other than
specified. Fire or electric shock could result.

CAUTION

A

1. Before turning on power, make sure wires are not
crossed or shorted. Fire or electric shock could result.

2. When mounting the unit on wall, install the unit in a
convenient location, but not where it could be
jarred or bumped. Injury could result.

3. Do not install or make any wire terminaiions while power
supply is plugged in. It can cause electrical shock or
damage to the unit.

4. Do not manually hold down hook switch while testing
and verifying call tone volume. The call tone is very
loud in earpiece, and could cause hearing damage.

5. Do not install the unit in any of the following locations.
Fire, electric shock or unit trouble could result.
— Places under direct sunlight, or near heating equipment

that varies in temperature.
— Places subject to dust, oil, chemicals.
— Places subject to moisture and humidity extremes, iOv

such as bathroom, cellar, greenhouse, etc. 'Sk
— Places where the temperature is quite low, such as inside

a refrigerated area or in front of air-conditioner.

6. On products with ground terminals, connect to an earth
ground. Fire or malfunction could result.

A GENERAL PRECAUTIONS

1. The unit is for domestic use only. Do not use outdoors.

2. When wall mounted, the unit may become dusty.
Clean with a soft cloth.

3. In areas where broadcasting station antennas are close by,
the intercom system may be affected by radio frequency
interference.

4. The unit case may become a little warm with use, but this
is not a unit malfunction.

5. If a cellular phone is used close by, the unit may malfunction.

6. Keep the unit more than 1 m away from Radio or TV set.

7. If the intercom station is operated near OA equipment.

Radio or TV, they interactively influence by radio frequency
interference. Carefully select locations for both installation
and operation.

STEP #1

Assign a Station number from 10 through 99.

• The YAZ-90-3W system does not require central
exchange unit and, therefore, assigning
Station number must be done on each Station.

• The YAZ-90-3W Station may have any number
from 10 through 99 according to users’
convenience.

• Be sure to assign a Station number for every
installed Station otherwise that Station would not
be able to receive calls.

» Do not assign a same number to more than one

Station.

4 WIRING ------------------------------------------------------------------------------------------------------------

1. Cable

Use twisted pair cable, not straight conductors. (Type CPEV, shielded)
(1) YAZ-90-3W station employs such components as CPU(microprocessor) and 1C chips. Twisted pair

cable must be used to prevent the unit from being interfered by line inductive noises generated by
the surrounding electricai appiiances and from crosstalk and malfunction caused by cable
conductors themselves.

(2) Keep at least 30cm (1 ’) away from other cable, like AC power lines, paging speaker lines or

telephone lines, or provide metal conduit for running cable.

2. Wiring distance

The total wiring distance should not exceed 2.9Km (1.8 mile) with 0.8mm dia. cable (20AWG).
(Ii+l2+i3 +

Note; The line loop resistance should not exceed 200 Ohm for communication line between the farthest

Notes;

• When power supply is installed in each Block:
#1,2 and 3 as shown in the left illustration, do
not connect terminals +, - between each Block.

• The loop resistance of power supply line
between PS-2420 power supply and the
farthest Station in each Block, should be less
than 20 Ohm.

• When locating power supplies for each Block,
count the paging adaptors as follows;

• one YAW-RB single-zone paging adaptor as
5 X YAZ-90-3W Stations.

4. Installation location requirements

In general, observe the installation location requirements as stated in PRECAUTIONS section.
When the YAZ system is installed outside the building, such as ski resort and/or between buildings, etc.
the cable has to be buried under ground in metai conduit. Be sure not to run the cable in midair which
can invite lightning surge and causes permanent damage to the YAZ system.

IMPORTANT WIRING INSTRUCTIONS

WIRING

• Use twisted pair cable.

• Connect 1st twisted pair to terminals 1 and 2, 2nd twisted pair
to terminals 3 and 4, 3rd twisted pair to 5 and 6 and 4>d twisted
pair to + and -. Do not cross wires.

■ Even if you have extra wires, do not use them for talk line.

Do not connect two or more wires to each number terminal.

PS-2420 POWER SUPPLY CONNECTION

• One PS-2420 power supply is required for every 30 Stations.

' Each PS-2420 power supply must be located near center

of each 30 Station group.

• The + and - lines must not be installed between each groups,
i.e. If the system includes 60 Stations, the 1st pS-2420 should
be connected to Station No.25 and the 2nd PS-2420 to Station
N0.55. Do not connect terminals + and - between Stations
N0S.39 and 40.

• If you have extra wires, it may be used for wiring to +, ­lines (never for talk lines). It is important, however, the line
resistance on +, - lines is equal as shown in the drawing.
