Add Paging, Loud Ringing and Background Music to Centrex, PABX, IP, or Key Systems
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 disipation, 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.
For more information on the PA-15, see DOD 486.
Add Paging and Loud Ringing with Background Music to Any Phone System
The PA-30 can directly drive up to thirty (30) 8 Ohm paging speakers or fifty (50) 70 volt or 25 volt paging
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
disipation, smaller size, higher reliability, and lower cost.
The PA-30 provides loud ringing and paging to electronic key systems, 1A2 Key systems, PABX's as
well as No-KSU phones and multi-line phones.
Paging is accomplished by connecting the PA-30 to a paging port or unused telephone line input (trunk
port) of nearly any phone system.
The PA-30 will also generate adjustable loud ringing from a ringing analog line or from a dry contact
closure. 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-30 eliminates the installation of multiple bells, relays and paging cards. The unit comes complete
with a power supply, and integrated 30 Watt amplifier.
For more information on the PA-30, see DOD 489.
60 Watt Compact Two Zone Amplifier to Drive up to 60 Paging Speakers
The PA-60 can directly drive up to sixty (60) 8 Ohm paging speakers or one hundred (100) 70 volt or
25 volt paging speakers. Both channels can be fed the same input so the PA-60 can be used as a
single large amplifier, or each channel can be fed different inputs so the PA-60 can be used as a two
zone amplifier.
This small and lightweight 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 disipation,
smaller size, higher reliability, and lower cost.
Since each input has its own gain adjustment, one zone can be turned up louder for warehouse paging
horn speakers, and the other zone can be turned down for office ceiling speakers. Two zones can also
be helpful for installations in which one group of speakers is connected to a source that provides
background music using the Viking PI-1A Paging Interface unit, and the other zone provides only
paging.
The Viking models CTG-1A or CTG-2A can be used to add clock controlled tones with paging to both
zones, or one zone can have just paging and be free of the time scheduled alert tones. The same can
be done with the Viking model MTG-10 in which one zone can have just paging, and the other zone
can have paging plus the 10 different siren, warble, and chime tones that the MTG-10 can provide.
One or two PA-60's can be added to the Viking model ZPI-4 four zone paging interface to provide either 60 Watts or 120 Watts of total paging power in four
zones. The PA-60 can also be used to add additional paging power to other Viking paging products such as the PA-2A, PA-15, and PA-30.
The PA-60's inputs are transformer coupled so they are floating and isolated. Because of this they can be connected to any line level audio signal, or by
turning down the input gain control to unity gain, can be connected directly to the output of another amplifier. This allows the PA-60 to be connected directly
to an existing paging system speaker wire run to extend the run, with up to 60 more speakers.
For more information on the PA-60, see DOD 493.
