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,

OPERATIONS
1. Calling & Communication (RA-A, RA-B & RA-D)
Press two-digit buttons of desired station (i.e.l 1 I , | 0 | for station #10). Note: Station numbers available: from 110 | to I If I for RAX-8 system
from 110 I to I 25 I for RAX-16 system from to I 33 I for RAX-24 system
The line is established when a short tone sounds as well as call LED gets illuminated, and talk handsfree. After communication, press p»~| (OFF) button.
When Busy Tone is heard; Short intermittent tone means called station is occupied.
You may press | * | button or hang up handset in RA-D to disconnect OR press | 0 |
(ME MORY) button to leave request for automatic call back. You will be automatically connected as soon as called station completes its conversation.
If your message is urgent; You may break in on the called station's conversation by pressing [ 0 | button. Called (Urgent Message or Break-in) station will receive signal and place present conversation on HOLD to reply.
When Privacy Tone is heard; Longer intermittent tone indicates called station is in Privacy Mode. You may wait for
station to release from Privacy Mode, as call tone will signal at the station in Privacy Mode for about 4 seconds.
2. Rceiving a call (RA-A, RA-B, RA-D & RA-C)
An incoming call is annunciated by a short tone and call LED illumination. Reply hands free. In RA-A you may pick up the unit and depress and hold the bar switch and in RA-D, pick up handset for private handset communication. After communication, press the
I » I (OFF) button or hang up handset in RA-D,
Urgent Message Break-in Signal; A short tone, like the call tone, received during a conversation indicates another station
is trying to reach you with an urgent message. Press [ 0 I (MEMORY) button to place present call on HOLD and automatically connect
you to the calling station. Touch I • I (OFF) button or hang up handset in RA-D to restore connection to station on HOLD and resume conversation.
Privacy I
To block out incoming calls and prevent monitoring, slide PRIVACY SWITCH to the right position. ' An incoming call is announciated by longer intermittent tone signalling about 4 seconds. Press | >i< | (TEMPORARY PRIVACY) button to reply hands free or, in RA-A, pick up the unit and hold the bar switch or, in RA-D, pick up hand set to reply. After communication press [ > | (OFF) button or hang up handset in RA-D and the station automatically returns to PRIVACY mode.
To release from Privacy Mode, slide PRIVACY SWITCH to the left position.'
* Setting or releasing from Privacy Mode must be made while your station is in standby mode.
