Viking FXI-1 Technical Practice
Viking’s FXI-1 universal paging interface allows you to provide paging
from virtually any type of phone system instead of from a microphone.
You can also provide background music and electronic night bell over
the audio system.
The FXI-1 provides 26V talk battery for interfacing with an FXO or
unused analog line input/trunk port. With the flip of a switch, the unit
can connect to a FXS or PABX station ring trip port. No power sup-
ply is required in this mode. In the event that it must be connected
to a “dry” 600 ohm paging port, the built-in voice activation (VOX) is
in control. This configuration is useful when interfacing with systems
that do not provide a paging contact closure, such as Panasonic,
South Western Bell, Intertel, etc.
In all modes the FXI-1 provides normally open or normally closed relay contacts to activate the
central paging amplifier equipment or connect to an external background music source. After
paging, the FXI-1 auto disconnects on CPC, busy signal, silence or default disconnect timer. An
electronic night bell over paging feature can be activated from a momentary phone system contact closure (FXO and page port mode only).

FCC REQUIREMENTS
This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA. On the side of this equipment is a label that contains, among other information, a product identifier in the format
US:AAAEQ##TXXXX. If requested, this number must be provided to the telephone company.
The REN is used to determine the number of devices that may be connected to a telephone line. Excessive REN's on a telephone line may result in the devices not ringing in response to an incoming call. In most
but not all areas, the sum of the REN's should not exceed five (5.0) To be certain of the number of devices that may be connected to a line, as determined by the total REN's, contact the local telephone company.
For products approved after July 23, 2001, the REN for this product is part of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point (e.g.,
03 is a REN of 0.3). For earlier products, the REN is separately shown on the label.
The plug used to connect this equipment to the premises wiring and telephone network must comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA. If your home has specially wired
alarm equipment connected to the telephone line, ensure the installation of this FXI-1 does not disable your alarm equipment. If you have questions about what will disable alarm equipment, consult your telephone
company or a qualified installer.
If the FXI-1 causes harm to the telephone network, the telephone company will notify you in advance that temporary discontinuance of service may be required. But if advance notice isn't practical, the telephone
company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the equipment. If this happens, the telephone company will provide advance notice
in order for you to make the necessary modifications to maintain uninterrupted service.
If trouble is experienced with the FXI-1, for repair or warranty information, please contact:
Viking Electronics, Inc., 1531 Industrial Street, Hudson, WI 54016 (715) 386-8666
If the equipment is causing harm to the telephone network, the telephone company may request that you disconnect the equipment until the problem is resolved.
Connection to Party Line Service is subject to State Tariffs. Contact the state public utility commission, public service commission or corporation commission for information.
WHEN PROGRAMMING EMERGENCY NUMBERS AND (OR) MAKING TEST CALLS TO EMERGENCY NUMBERS:
Remain on the line and briefly explain to the dispatcher the reason for the call. Perform such activities in the off-peak hours, such as early morning or late evenings.
It is recommended that the customer install an AC surge arrester in the AC outlet to which this device is connected. This is to avoid damaging the equipment caused by local lightning strikes and other electrical
surges.

A. Adding Background Music
If background music is not available on the central paging amplifier, the FXI-1 can be wired as shown below. This application works in all modes and the music is suppressed during paging.
Up to 6 FXI-1 units can be wired as shown below and share a single 12V 500mA adapter. This is useful in the FXO or
VOX (powered) mode.
B. Recommended Wiring to Eliminate Idle Noise and Clicks
