VIKING
Viking’s FXI-1A 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-1A provides 30V talk battery for interfacing with an FXO,
plain old telephone, 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-1A 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-1A auto disconnects on CPC, busy signal, silence or page timer.
An electronic night bell over paging feature can be activated from a
momentary phone system contact closure.

A. Page Input Type
1. FXS (Ring Trip) Mode (Not Using the Included Power Supply)
Use one of the following three diagrams (depending on the type of page input that will be used), to
connect the paging source. In all three cases, the 600 Ohm Audio Output can connect to a paging
amplifier. The Relay Contacts can be used to either switch in and out background music (See
Installation section B), or trigger the paging amp (See Installation section C).
Select this mode if connecting to a FXS Port, or a Ringing PABX Extension. The FXI-1A will
answer a ringing line, activate its relay, and pass the paging audio onto the amplifier. It will then
drop the call based on Page Time Out, Silence Time Out, detecting a Busy Signal or Calling
Party Control (CPC). See Operation section A for further details.
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.

Select this mode if connecting to a FXO Port, a Plain Old Telephone, or a Trunk Input of a PABX
or Key System. The FXI-1A provides 30 VDC Talk Battery. When the port, phone, or trunk has
seized the line, the FXI-1A will activate its relay, and audio will pass through the FXI-1A to the
paging amplifier. See Operation section B for further details.

Select this mode if connecting to a Paging Port. When the FXI-1A detects audio it will activate
its relay and pass the paging audio onto the amplifier until the Silence Time Out is reached. See
Operation section C for further details.
Note 1: The Page Alert Tone is not recommended in this mode, so keep DIP Switch 1 in the
OFF position.
Note 2: Since this mode is dependent on detecting audio, it is important to set the Silence Time
Out POT to a time setting that works best for the application. It is also recommended to keep
the Busy Detect feature disabled (DIP Switch 2 OFF), and to set the Page Time Out POT to the
Disabled position (fully clockwise). This way the FXI-1A stops paging only when the paging
source goes silent.

If there is not a background music input on the paging amplifier, the FXI-1A relay contacts can be
used as shown below to add a background music source. This application works with all paging
input types (FXS, FXO, and VOX), and the music is suppressed during paging.
If the FXI-1A relay contacts are not being used for adding background music (as shown above),
they can be used as a page trigger. Connect the common and normally open contacts to the paging
amplifier’s Page Trigger input. The contacts will provide a contact closure when paging is active.
If the phone system provides a
“Night Bell” contact closure output,
it can be connected as shown
below. The FXI-1A will produce a
loud ringing warble tone on contact
closure. Not compatible with FSX
(Ring Trip) Mode. See Operation
section D for more details.

If the phone system does not provide a “Night Bell” contact closure output, loud ringing can be
achieved from a ringing station, or a ringing FSX port, with the addition of a Viking Model K-600F
Night Bell Over Paging Adapter. The two products can be wired so that either paging has priority or
loud ringing has priority. If both events happen at the same time, the higher priority will take
precedence. The loud ringing warble tone will follow the cadence of the incoming ring signal.

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-1A provides 30V talk battery to connect to
an FXO port, trunk input, 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-1A is triggered by ring voltage to
seize the line, it is then powered by the talk battery being provided, so the supplied 12VDC power supply is
not needed.
NOTE: If both the Page Time Out POT and Silence Time Out POT are turned to the “Disabled” position, and if
the phone system does not provide a CPC or Busy Signal, the FXI-1A will appear as if it is locked up. In actuality,
the FXI-1A simply does not have anything to tell it the page has ended. When this happens, the only way to clear
the ongoing page is to power down the unit by disconnecting the power and/or disconnecting it from the ringing
station. Be sure to move the Page and Silence Time Out POTS from the “Disabled” position before reconnecting.

FXS Power Assist (Ring Trip) Mode - Power Required
In this mode an external power adapter is typically needed. The unit can be powered by a ringing line and will
answer after 1 second at which time it will activate the relay contacts and provide a pre-page alert tone if enabled
(Dip switch 1). The FXI-1A will release the relay and hang up after a break in loop current (CPC) or if any of the
following are enabled; silence time out, busy detect, or page time out.
In this mode the unit waits until loop is detected (when a FXO port, telephone, or PABX trunk coming off hook),
then activates the relay contacts and provides a pre-page alert tone if enabled (Dip switch 1). The FXI-1A will
release the relay, end the page, and provide a 2 second CPC signal, on either loss of loop current or if any of the
following are enabled; silence time out, busy detect, or page time out.
Dip switch 4 and 5 must be ON and the Talk Battery switch should be in the FXS position. In this mode the unit
waits until audio is detected then activates the relay contacts. The FXI-1A ends the page when audio stops and
the silence time out is met.
If the unit is powered 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 may have trouble powering a relay
from this weak signal.
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”.
