V. Installation Guidelines
BE SURE TO TURN OFF RAX POWER SUPPLY BEFORE YOU OPEN THE UNIT OR
MAKE WIRING CONNECTIONS.
1. Central Exchange Unit (CEU);
* Select location for CEU that will facilitate ease of access to the unit itself.
* Plug the power supply into a clear line. Interference on the power line may cause function error.
* Select a location that:
— has low humidity.
— is free of dust.
— is vibration free.
— is free of static electricity.
— is not near flammable or chemical product.
— is not close to high voltage equipment.
— is not within a strong magnetic field.
— is not near heating or air conditioning outlets or equipment.
— does not have direct sunlight.
— does not have temperature extremes: below 0°C (+32^F) or above + 40°C (+104^F).
2. Station;
* Each station must be home run wired to the C.E.U. individually, and must have individual station numbers.
* Follow location guidelines for the Central Exchange Unit when selecting station location.
* Avoid locations where temperature dips below —10°C (+14°F) or exceeds +60°C (+140°F).
* Select a most suitable type of station according to your communication requirements and environmental conditions.
3. Wiring;
* Use 2 twisted pairs for each station.
* Keep twisted pair cable well apart (over 50 cm or 20'") from other cables such as heavy duty power lines, telephone
lines and/or paging amplifier output line (speak line).
4. Installation;
* In new construction install single-gang box for RA-A or RA-D stations or electrical box (see page 14) where
RA-B or RA-C stations are to be wall-mounted. The station wilt cover the hole, when installed.
-7 -

VI. Wiring
There are two basic wiring methods for RAX system.
In either case, you must use two twisted pair per station.
METHOD 1: 2 twisted pair in home run manner from each station to RAX Centra! Exchange Unit.
METHOD 2: More than one station can be run in multiple twisted pair cable.
DO NOT RUN SPEAKER LINE IN MULTIPLE PAIR CABLE FOR STATIONS.
* A combination of the above methods may also be used.
Refer to the chart below and select wire gauge required for your installation;

PAGING/REMOTE CONTROL
The RAX system has the capacity of paging up to four separate zones and All Page.
Each zone requires one paging adaptor Model: MC-A, one amplifier and proper number of speakers for the amplifier output
(and one PB-YKX talkback paging adaptor is required for talkback). NOTE: All Page is a system function and does not require
special equipment or wiring.
NOTES: 1. If the system includes a remote control device, one paging terminal must be used for the RC-B remote control
adaptor. This will reduce the number of paging zones to 3.
2. Adding zones of paging and/or remote control does not reduce the station capacity of the system (i.e. a 24-
station system may have 24 stations plus 4 zones of paging and/or remote control).
3. If an RC-A adaptor is installed for each zone, only one MC-A paging adaptor and one amplifier is required for
zone page/AII Page. Talkback will require one PB-YKX talkback adaptor.
WIRING REQUIRED
2 twisted pair cable or multiple twisted conductor cable may be used for connecting station to RAX terminal board.
Wiring is polarized in each twisted pair. These cables must be twisted pair.
Connection to MC-A adaptor requires two common plus one individual conductors from CEU terminal board.
* Regulator unit in CEU must be earth grounded.
Do not run speaker line in the same cable with station wires.

RAX SYSTEM DIAGRAM AND WIRING EXAMPLE
RAX Central
Excharge Unit
In case you want to include RA-C sub station in your RAX system, the RA-C station number must be assigned in consecutive
numerical sequence, either the number before or after the number of the master station, such as [To] - [HI - DU " Dl]
. . . [32] - [33] .
Example: When RA-C sub station is connected to terminal No. 10 and RA-A (RA-D or RA-B) master station is connected to
terminal No. Impressing 0 on RA-C station No. 10 calls master station No. 11 or vice versa. Any other station
may call the RA-C station No. 10 by pressing pTI, [0] .
NOTE: 1. The lower number in a pair of stations must be an even number, such as |l0| — Qj] , . . . [Ts] — [lU ■ • •
m-M ■ u • • ,
2. To make a pair of master/sub, master station may be connected to either station number in a pair, lower or
higher, as shown below;
Example: 10 _D_
rA-A RA-C \ Either combination will be acceptable for master/
RA-C RA-A j sub communication between Station No. 10 and 11.

YII. RAX System Installation
(A) Mounting Central Exchange Equipment
* Be sure to turn off the power switch on the RAX C.E.U. before you open the unit OR make wiring connections.
** The location of Central Exchange Equipment must meet the following criteria;
1. Ambient temperature range: 0°C to +40°C (+32°F to +104^F).
2. Area must be as dust free as possible, and not too dry or too humid.
3. Units must be wall mounted.
4. Avoid static electricity.
There are* two basic methods (shown below) of mounting equipment.
If the adaptor(s) and amplifier(s) must be located in an area exposed to people, use of a cabinet is recommended to reduce the
possibility of someone changing level controls, or damaging wiring.
It is recommended that the Central Exchange Unit not be installed inside of the cabinet, which could restrict ventilation.
If the equipment is to be installed in an electrical room or cabinet, it is recommended that a piece of 1.2 cm (1/2") plywood of
adequate size be secured to the wall first and equipment then mounted to the plywood. This will insure adequate backing for
mounting screws, incoming cable distribution, and tie down.

2. Install the mounting bracket to the gang boxes
with the provided screws.
Anchor the bracket with the provided screws or
bolts at 4 points.
3. Mount the RAX Central Exchange Unit onto the
bracket, and connect wires for both stations and
AC power line.
4. Replace the covers.

Notes on installing station units;
(1) Avoid to locate the station unit in such places as closely surrounded by wall or other things, which may interfere with
voice-switching to function properly.
(2) Keep the station unit away from the paging speakers to avoid acoustic feedback in paging mode.
