The RAD-1A can be used to access paging systems remotely. The RAD-1A can hang-up on
silence. Use a low value like 2 or 3 seconds for the silence time out setting (see Programming
section D). If no audio is detected in the programmed amount of time, the RAD-1A will disconnect.
The RAD-1A can be used to access paging systems remotely. If the RAD-1A is to be used with a
paging system that requires Touch Tone zone selections, the RAD-1A can be set to ignore Touch
Tones. Setting DIP switch 1 to the ON position (see below) will disable the RAD-1A’s ability to see
Touch Tones so commands are only seen by the paging system. Be sure to set DIP switch 1 to the
OFF position if additional programming is needed.
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.

Operation
The RAD-1A allows remote access to any 600 ohm audio device. This can be very useful
for remote access to paging systems. The RAD-1A will answer an incoming call on the first
ring. The RAD-1A offers either unsecured access, or secured access to the 600 Ohm
input/output of one-way paging amplifiers, digital announcers and other audio programs.
When an access code has been programmed, the RAD-1A answers the inbound call
and prompts the caller with a single beep. The caller is then required to enter a 1 - 6
digit access code. If the proper access code is not entered within 20 seconds, the
RAD-1A will triple beep and hang up. When a valid access code has been entered, the
RAD-1A will double beep (if alert tones are ON) and bridge the line to the device
connected to the RAD-1A’s output.
Important: It is crucial that the installer and system owner understands the functions
and capabilities of both the RAD-1A and the lines and/or PABX stations connected to
the RAD-1A, so that any and all toll fraud and other system abuse possibilities are
understood. This enables the installer and owner to make risk managing decisions about
the system into which the RAD-1A is installed. Viking Electronics Inc. is not able to
assume responsibility since it is a function of the entire system assembled by the
installer/owner. A Viking TR-1 Toll Restrictor may be added to help prevent toll abuse if
the PABX and RAD-1A toll restriction is not adequate, see DOD 705 for more
information.
A. Unsecured Access
If the access code has not been programmed, the unit is “Unsecured.” In this mode, the
RAD-1A answers the inbound call, double beeps (if alert tones are ON), and bridges the
line to the device connected to the RAD-1A’s output.
B. Secured Access (Dip Switch 1 OFF)

The DVA-2WA is a digital announcer with a
built in 2 watt amplifier. Designed to provide
music and promotion on hold, the DVA-2WA
can playback in a continuous loop or alternate
between promotions and an auxiliary music
source in timed intervals. Any number of
multiple messages may be recorded.
The announcer comes with four professionally
pre-recorded promotion on hold messages, a
power supply and cabling for an easy plug and
play installation.
The output of the DVA-2WA may also be
connected directly to loudspeakers for repeated messages or played at the push of a button
for museum displays, information booths, point of interest locations, retail applications, etc.
The DVA-2WA’s non-volatile memory eliminates the need for batteries or costly built in tape
decks. This provides the convenience of recording at the shop or professional studio and
then shipping to the installation site.
Add Paging and Multiple Line
Loud Ringing to Any Phone System
The PA-2A provides loud ringing and paging
to electronic 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 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-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) Viking 25AE paging horn.
