VIKING
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 30V 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
supply 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).
Power: 12-24V DC @ 100mA, 120V AC/12V DC @
500mA, UL listed adapter included (not required in FXS
mode)

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.
IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges from both the AC
outlet and the telephone line. It is recommended that a surge protector be installed to protect against such surges.

In this mode, the unit is powered by the ringing line and answers after 1 second, activates the relay contacts and
provides a pre-page beep if enabled (dipswitch 4 on). If more than 2.5 seconds of silence, a busy tone (default
timer >16 seconds), or a CPC are detected, or the default timer expires, the unit releases the relay and drops
the line.
In this mode, the unit waits until loop is detected, then activates the relay contacts and provides a pre-page beep
if enabled (dipswitch 4 on). If more than 2.5 seconds of silence or a busy tone (default timer > 16 seconds) is
detected, or the default timer expires, the unit releases the relay and provides a 2 second CPC.
An FXO port is an analog input RJ11 port just like a POTS trunk input on a PABX or key system. An FXO port
receives talk battery and ring voltage. In the FXO mode, the FXI-1 provides 30V talk battery to connect to an
FXO port or plain analog phone.
An FXS port is an analog output RJ11 port just like a station port on a phone system or PABX extension. It
provides talk battery, dial tone and ring voltage. In the FXS mode, the FXI-1 is triggered by ring voltage to
seize the line, it is then powered by the talk battery being provided.

FXS Power Assist (Ring Trip) Mode - Power Required
In this mode, the unit waits until audio is detected, then activates the relay contacts. If more than 2.5 seconds of
silence or a busy tone (default timer > 16 seconds) is detected, or the default timer expires, the unit releases the
relay. There is no pre-page beep in this mode.
If the unit is installed in FXO or VOX mode and not currently paging or providing a CPC, a momentary closure
on the Night Bell input for 50mS or more will trigger a 1 second pause followed by relay activation, a 1.5 second
warble tone, and relay release. A continuous closure on the night bell input causes the 1 second pause, 1.5
second warble tone cycle to repeat until the closure is removed.
Some VoIP products provide a low power ring signal designed for electronic phones that adaptor-
powered equipment can detect easily, but line-powered equipment has trouble using to activate a relay.
In this case it is recommended to use FXO (Loop Start) mode if possible by changing to an unused
trunk input, otherwise connect the equipment as shown in the special “FXS Power Assist (Ring Trip)
Mode”.
In this installation, a short page may be heard when the unit is powered on, but will then function as
normal.

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.
PART 15 LIMITATIONS
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
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.
