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 CED 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 will cover the hole, when installed.
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 Central 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;

PAGIIMG/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 jlOl — |11| , |12| — [T^
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. 11, pressing | | 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 [jJ , .
NOTE: 1. The lower number in a pair of stations must be an even number, such as pT^ — [U] . • • ■ il8| — jl9| . . .
- [25] .
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_________11
RA-A RA-C I Either combination will be acceptable for master/
RA-C RA-A I sub communication between Station No. 10 and 11,

VII. 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 foilowing 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.

X. Post Installation System Testing
Once installation is finished, testing is recommended prior to indoctrination of used personnel regarding operation of the system.
Proper installation of the RAX system, and its full range of communication functions, can be tested with three simple steps.
Step 1: Checking Station-to-Station Communication
• Select one station as the key station. Label it "S-1". Label remaining stations "S-2" through "S-n".
• Call S-2 from S-1 and confirm communication.
• Call S-1 from S-2 and confirm communication.
• Repeat process from S-1 to S-n until each station in the system has been tested.
Step 2: Checking Busy Tone signal
Using three stations (S-1, S-2 and S-3)
• Call S-1 from S-2.
• While S-2 is calling S-1, call S-2 from S-3 to confirm that Busy tone signal is heard.
Step 3: Checking Paging Function (If applicable)
Using S-1, page each zone (touch |j^ and 1,2,3 or 4), then depress Talk button to confirm paging is transmitted
to selected zone (If talkback function is included, release | t \ Talk button to confirm talkback). To check remote
control operation, touch | | and zone number button connected to the external devices, and momentarily depress [ t |
Talk button in handset. Depress button to confirm either continuous or intermittent tone.
Upon completion of the above tests, if any of the remaining communication functions are not found to work as pre
scribed in the Operations Manual, the cause is not due to improper installation. Rather, the Central Exchange Unit must
be checked. If this is the case, an Aiphone Specialist must be consulted.
XL User Indoctrination
Upon completion of post installation testing and confirmation of the system being fully operable, used personnel should
be indoctrinated as to how to use the system.
The Operation Manual clearly describes all of the communication features of the system. A complete understanding of
the operation of the system by those who will be using it well avoid post installation call backs and related service.
* Special Instructions:
(1) Please turn on the power switch on the RAX C.E.U. after all the equipment wiring is completed. If intercom sta-
tion(s) would be connected after system powered on, the station(s) would not work properly. Please turn off the
power switch temporarily for about 10 seconds.
(2) Do not make temporary operation of turning ON and OFF power switch again and again. At least 3 seconds have to
elapse between ON and OFF operations.

XIII. Servicing
1. Be sure to turn off power switch on RAX C.E.U, before you remove the cover of Central Exchange Unit.
2. Removing the cover of Central Exchange Unit will automatically activate the automatic switch and shut off the power.
When the system has to be powered for testing, the automatic cutoff switch must be in a depressed position.
3. As the printed circuit boards in Central Exchange Unit employ MOS-ICs, do not touch the printed circuit boards. Doing
so may damage the printed circuit boards with static electricity discharged from your fingers.
4. Before removing the printed circuit board: XC-063 (subscriber card), wait until all three (3) LEDs go out on the mother
board (XC-064) after the power is off.
5. Before replacing any station, be sure to turn off the power supply.
6. When your RAX system includes paging amplifier(s) or remote control devices, turning on and off will cause noise through
paging speakers and switchover of the remote control ON/OFF mode of the remote control devices. This is not due to
equipment failure but rather what occurs when the power supply is turned on or off.
7. When replacing Cards, locate the Card in the right position by matching color of the Card with that on the chassis. Locate
the subscriber card (XC-063) as from the position next to the voice-switching card (XC-062).
