PRODUCT MANUAL
Designed, Manufactured and Supported in the USA
COMMUNICATION & SECURITY SOLUTIONS
Add Paging, Loud Ringing and Background Music
to Centrex, PABX, IP, or Key Systems
Features
The PA-15 interfaces with virtually any telephone system
to provide 15 watts of paging power - enough to drive
fifteen 8-ohm paging horns or speakers. This small and
light weight chassis design is possible by utilizing new
amplifier technology that is 300% less inefficient than old
designs competitors use. High efficiency means much
less heat dissipation, smaller size, higher reliability, and
lower cost.
The PA -15 provides 36V 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/Centrex station ring trip port or connect to a 600
ohm paging port. When interfacing with systems that do
not provide a paging contact closure, the built-in voice
activation (VOX) is in control.
After paging, the PA-15 auto disconnects on CPC, busy
signal, silence, or default disconnect timer (helps prevent
accidental paging system lock-up if phone is hung-up
incorrectly). The unit will generate adjustable loud ringing
from an independent ringing analog FXS/PABX/Centrex
station or from a dry contact closure. The PA-15 can
provide background music (muted during page) if
connected to an external music source.

This input provides loud ringing through the speakers whenever ringing voltage is detected. Connect an analog
ringing line to screw terminals 9 & 10 for this feature.
B. Loud Ringing
1. Ringing Line
Some phone systems provide a “common audible” dry contact closure whenever a call is coming in. Wire the
contact closure across screw terminals 11 & 12 for this feature.
DIP Switch 5 ON: This input provides a door chime through the speakers when a contact closure is detected.
DIP Switch 5 OFF: This input provides loud ringing through the speakers when a contact closure is detected.
2. Contact Closure
This input can be used to disable loud ringing. For example, if loud ringing is only necessary during off business
hours, an external switch can be added to disable loud ringing during the day, and transfer it back on at night.
Connect an external switch across screw terminals 11 & 12, when the switch is closed, the loud ringing sound
(or door chime if DIP switch 5 is ON) will sound once and loud ringing will be disabled. When the switch is
opened, a double beep will be heard (if DIP switch 5 is OFF) through the speakers to indicate loud ringing
enabled. When the switch is closed the door bell button will not work. If night transfer and door bell button are
required, use Viking model MTG-10 to connect the door bell button. Connect the MTG-10 to the music input
of the PA-15.
3. Night Transfer
The PA-15 can produce one of 4 selectable loud ringing sounds. Use DIP switches 1 and 2 to choose between
Electronic Warble, Double Gong, Quadruple Chime, or Door Chime sounds. Select the Electronic Warble tone
(traditional loud ringing) for noisy areas. The softer chimes work well in quieter environments. The loud ringing
volume can be adjusted with the trim POT in the middle (R13).
4. Loud Ringing Sounds
The PA-15 can be interfaced to an analog extension or FXS port by setting the FXO/FXS switch to FXS and
connecting the wires to screw terminals 5 & 6. In this mode a ring signal triggers the PA-15 to grab the line,
send a tone over the line, and then (if DIP switch 8 is on) over the speakers, after which you may speak. The
PA-15 will end the page when either a busy signal (if default timer is not 16 seconds) or CPC is detected, or
the silence timer (DIP switches 3 & 4) or default timer (DIP switches 9 & 10) runs out. Paging audio volume
can be adjusted with the trim POT on the left (R6).
C. Paging
1. Analog Extension or FXS port
The PA-15 can be interfaced to a trunk input, FXO port, or analog phone by setting the FXO/FXS switch to
FXO and connecting the wires to screw terminals 5 & 6. In this mode an off hook condition triggers the PA-15
to pause 1 second, send a tone over the line, and then (if DIP switch 8 is on) over the speakers, after which
you may speak. The PA-15 will end the page with a 2 second CPC when either a busy signal (if default timer
is not 16 seconds) or hang up is detected, or the silence timer (DIP switches 3 & 4) or default timer (DIP
switches 9 & 10) runs out.
2. Trunk Input, FXO port, or Analog Phone
The PA-15 can be interfaced to a phone system paging port by setting the FXO/FXS switch to FXS, turning
DIP switch 6 ON, and connecting the wires to screw terminals 5 & 6.
With Page Contacts: If the phone system supplies a page contact, wire it to screw terminals 7 & 8. When the
contact closes the PA-15 will send a tone to the port and then (if DIP switch 8 is ON) over the speakers, after
which you may speak. The PA-15 will end the page when the contacts open.
Without Page Contacts: If the page contacts are not used, then the PA-15 relies on a Voice Activation Switch
(VOX) feature that will switch to paging when voice audio is detected. In this mode the PA-15 does not have
the opportunity to supply a page alert tone. The VOX sensitivity can be adjusted by turning DIP switch 7 ON
to reduce the sensitivity if noise on the wires creates false pages. The PA-15 will end the page when the silence
timer (DIP switches 3 & 4) or default timer (DIP switches 9 & 10) runs out.
3. Paging Port
This audio output is provided so that additional paging amplifiers can be added if additional paging power is
needed. This is a 600 ohm line level output that can be connected into any single ended amplifier input (such as
a second PA-15 or a PA-60).
D. 600 Ohm Output
Note 1: Mount the amplifier close to where the speakers are installed to minimize the speaker wire run lengths.
Note 2: Using half the recommended distance or half as many speakers per run will keep the volume lost limited to 3db.
Note 3: Doubling up the wires will allow double the length, or reduce the amount of volume loss.
Note 4: Heavier gauge wire, fewer speakers per run, and shorter runs will all minimize volume loss.
7
The PA-15 contains a high current amplifier which can drive up to fifteen 8-ohm speakers. The more speakers that
are used, the less shared power each speaker will receive, the softer they will each play. A single speaker with a
short speaker wire run will receive the full 15 watts of power, where if 15 speakers are used, there will be less then
1 watt of power available for each speaker. See DOD 895 for additional information on paging horn volume per
number of speakers being used. If additional paging power is needed, add a Viking model PA-60 for 60 more watts
of paging power.
Another consideration when budgeting speakers is paging power that is lost in the wire runs. A single speaker on
a short heavy gauge wire will have no loss, but many speakers on a long light gauge wire will have an unacceptable
amount of volume lost. Use the below chart as a guide line to keep the volume lost limited to less then 5db. Using
half the recommended distance or half as many speakers per run will keep the volume lost limited to less then 3db.

All tones require a minimum of 180mS of ringing voltage (or 50mS contact closure) to trigger. Once triggered, the
loud ringing sound selected by DIP switches 1 & 2 will be created as per the chart below and on page 8. The ringing
must stop or the contacts must open for at least 50mS before the PA-15 can produce another loud ringing sound.

RETURNING PRODUCT FOR REPAIR
The following procedure is for equipment that needs repair:
1. Customer must contact Viking's Technical Support Department at 715-386-8666 to obtain a Return Authorization (RA) number. The customer MUST have a complete description of the problem,
with all pertinent information regarding the defect, such as options set, conditions, symptoms, methods to duplicate problem, frequency of failure, etc.
2. Packing: Return equipment in original box or in proper packing so that damage will not occur while in transit. Static sensitive equipment such as a circuit board should be in an anti-static bag,
sandwiched between foam and individually boxed. All equipment should be wrapped to avoid packing material lodging in or sticking to the equipment. Include ALL parts of the equipment. C.O.D. or
freight collect shipments cannot be accepted. Ship cartons prepaid to: Viking Electronics, 1531 Industrial Street, Hudson, WI 54016
3. Return shipping address: Be sure to include your return shipping address inside the box. We cannot ship to a PO Box.
4. RA number on carton: In large printing, write the R.A. number on the outside of each carton being returned.

The following procedure is for equipment that has failed out-of-box (within 10 days of purchase):
1. Customer must contact Viking’s Technical Support at 715-386-8666 to determine possible causes for the problem. The customer MUST be able to step through recommended tests for diagnosis.
2. If the Technical Support Product Specialist determines that the equipment is defective based on the customer's input and troubleshooting, a Return Authorization (R.A.) number will be issued.
This number is valid for fourteen (14) calendar days from the date of issue.
3. After obtaining the R.A. number, return the approved equipment to your distributor, referencing the R.A. number. Your distributor will then replace the Viking product using the same R.A. number.
