• Two watts of paging power
• All lines are optically coupled for compatibility
with fax switches and analog PABX/KSU
stations
• Can provide background music from an external
source (trunk mode only)
• Paging from an unused trunk port or paging port
• Choose one of four ringing sounds:
- Electronic warble (traditional loud ringer)
- Double gong (two identical “gong” tones)
- Quadruple chime (four descending chime tones)
- Door chime (ding-dong)
• Provides loud ringing or night bell, from 1-6 lines
for warehouses, yards, etc.
• Output for controlling a 12 volt relay from 1-6
ringing lines
• Page alert tone (trunk mode only)
• 600 ohm output for sourcing high powered
amplifiers
The PA-2A provides loud ringing and paging to elec-
tronic key systems, 1A2 Key systems, PABX’s as
well as No-KSU phones and multiline phones.
Paging is accomplished by connecting the PA-2A to
a paging port or unused telephone line input (trunk
port) of nearly any phone system.
The PA-2A will also generate adjustable loud ringing
from up to 6 analog lines or from a dry contact clo-
sure. Either a loud electronic warble, or one of three
other soft chime sounds may be selected. An external “night transfer” switch can be
added to turn loud ringing on or off in night bell applications.
The PA-2A is easy to install and eliminates the installation of multiple bells, relays and
paging cards. The unit comes
complete with a power supply,
amplifier and (1) paging horn.

Technical Support Department at 715-386-8666 to obtain a Return Authorization (R.A.) number.
This warranty does not cover any damage to the product due to lightning, over voltage, under voltage, accident, misuse, abuse, negligence or any damage caused by use of the product by the purchaser or others.
Vikings sole responsibility shall be to repair or replace (at Viking's option) the material within the terms stated above. VIKING SHALL NOT BE LIABLE FOR ANY LOSS OR DAMAGE OF ANY KIND INCLUDING INCIDENTAL OR CONSE-
QUENTIAL DAMAGES RESULTING DIRECTLY OR INDIRECTLY FROM ANY BREACH OF ANY WARRANTY EXPRESSED OR IMPLIED, OR FOR ANY OTHER FAILURE OF THIS PRODUCT. Some states do not allow the exclusion or limi-
tation of incidental or consequential damages, so this limitation may not apply to you.
THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, WHICH ARE HEREBY EXCLUDED
BEYOND THE ONE YEAR DURATION OF THIS WARRANTY. Some states do not allow limitation on how long an implied warranty lasts, so the above limitation may not apply to you.

The PA-2A uses the USOC jacks RJ11C, RJ14C, and RJ25C.
It is recommended that the customer install an AC surge arrester in the AC outlet to which this device is con-
nected. This is to avoid damaging the equipment caused by local lightning strikes and other electrical surges.
This equipment is Hearing-Aid Compatible (HAC).
The telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other
electronic device, including fax machines, to send any message unless such message clearly contains in a mar-
gin at the top or bottom of each transmitted page or on the first page of the transmission, the date and time it is
sent and an identification of the business or other entity, or other individual sending the message and the tele-
phone number of the sending machine or such business, other entity, or individual. (The telephone number pro-
vided may not be a 900 number or any other number for which charges exceed local or long-distance transmis-
sion charges.)
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 radi-
ate 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. Located on the equipment is a label that contains,
among other information, the FCC registration number and ringer equivalence number (REN). If requested, this
information must be provided to the telephone company.
The REN is used to determine the quantity of devices which may be connected to the telephone line.
Excessive REN's on the 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 the line, as determined by the total REN's, contact the telephone company to deter-
mine the maximum REN for the calling area.
This equipment cannot be used on the telephone company-provided coin service. Connection to Party Line
Service is subject to State Tariffs.
If this equipment causes harm to the telephone network, the telephone company will notify you in advance
that temporary discontinuance of service may be required. If advance notice isn't practical, the telephone com-
pany 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 in order to maintain uninterrupted service.

When interfacing the PA-2A to a paging port, the TALK BATTERY switch (DIP switch 4) must be OFF. The PA-2A will
amplify all signals sent from the paging port.
When interfacing with an unused telephone line input (trunk port), the TALK BATTERY switch (DIP switch 4) must be ON
and the PA-2A must be connected to an unused trunk port. Simply access that trunk port and talk into the handset to page.
A page alert tone may be enabled or disabled with DIP switch 3. When the page alert tone is enabled, paging will interrupt
and hold off loud ringing for the duration of the page.
In both instances, the PA-2A can monitor 1 - 6 C.O. lines, 1 - 6 analog PABX/KSU stations or a dry contact closure for loud
ringing. The PA-2A will produce the selected ringing tone when ring voltage is detected on these line inputs or a contact is
closed on pins 3 and 4. Select the electronic warble tone (traditional loud ringing) for noisy areas. The softer chime tones
work well in less noisy environments.
All tones require a minimum of 180ms of ringing voltage (or contact closure) to trigger. Once triggered, the electronic war-
ble will run continuously until ringing stops (or contacts open). All other tones (double gong, quadruple chime, doorbell) will
run through their full sequence once and will not cycle again until the ringing stops (or contact opens) for at least 50ms and
a second ring signal (or contact closure) triggers them again.

Even the best designed paging systems can experience feedback. Now you can elim-
inate annoying feedback over your paging speakers with Viking’s model FBI-1A dig-
ital anti-feedback paging interface.
The FBI-1A utilizes state of the art digital recording technology to record the “live”
page from a phone system’s paging port output or unused trunk port. The FBI-1A
then immediately plays back the recorded page once or twice (selectable) over the
paging system.
Pages of up to 16 seconds (expandable to 60 seconds) can be stored and the FBI-
1A automatically adjusts to the page length for faster processing. In addition, the FBI-
1A can be programmed to provide pre-page and post-page alert tones.

The M15W is designed to add more paging power to almost any amplified paging
product, or it may be used as a primary paging amplifier.
Audio can be input from a 600 ohm source or from an 8-ohm amplified source. The
15 watt output can drive an eight to four ohm load, or two separate two-ohm loads,
which simplifies installation of up to eight 8-ohm speakers. Installation of up to 32
speakers is possible. A power adapter and
one 25AE Paging Horn are included. ?Need More Information on the M15W?

The CPA-7B is a cost effective, multi- purpose, telecom paging system. The unit
features a low noise, high fidelity amplifier, providing 6 watts of power for a variety
of telecom paging applications. It can also provide background music and night
bell/common audible. In addition, multiple units may be daisy-chained for larger
paging applications.
The CPA-7B allows paging from any one of the following: an unused trunk input, a
page port, a C.O. line, Centrex line or analog PABX/KSU station port. For loud ring-
ing, the CPA-7B generates an adjustable loud warble from a dry contact closure, a
ringing C.O. line or a ringing analog
PABX/KSU station port. ?Need More Information on the CPA-7B?

The 25AE and 30AE paging speakers provide additional economi-
cal paging coverage to existing Viking paging units (PA-2A, CPA-
7B, HF-3W, M2W) or to any system with an 8 ohm output.
In outdoor, factory or warehouse environments, 25AE paging horns
are the best method of producing understandable sound. In these
environments the directional design allows the installer to focus the
sound cone down aisles and toward work areas.
In office and restaurant environments, it is best to distribute sound
more evenly. Ceiling mounted 30AE speakers in close proximity
offer the best distribution and are cost effective.
The 25AE Paging Horn features: adjustable base for easy mounting and directional adjustment, compact design for out of
the way mounting, and is designed to work with all of Viking’s paging products.
The 30AE Ceiling Speaker features: attractive white grill for flush mounting in office ceiling, mounting hardware included,
large permanent magnet, excellent frequency response, and is designed to work with all of Viking’s paging products.
