Line Powered Remote Access Device
The RAD-1, remote access device, gives authorized users remote access to PABX, Centrex and
Electronic Key system features. It can also provide
bridging to a second central office line. With two
levels of access and programmable toll restriction,
the RAD-1 provides the security required to help
prevent phone system and toll abuse.
The RAD-1 answers on the first ring and disconnects on CPC, time out or by dialing #7. The 600
ohm LINE OUT port provides loop closure for audio
access to system features or an external device. For “line extender” applications, the
user does not have to hang up and redial the RAD-1 to make another call. The RAD-1
will also provide a hookswitch flash on the LINE OUT port to access PABX, Centrex or
Electronic Key system features.

This product does not eliminate the possibility of toll
fraud! To further protect against fraudulent calls, use
with a TR-1 Toll Restrictor (Fax Back Document 705).

Programming
A. Security Code
The security code allows the user/installer to program the RAD-1. The factory preset security code is 845464 (V-I-KI-N-G). To program your personal security code follow the directions below.
Step 1. Call into the RAD-1.
Step 2. Dial ✱ followed by 845464 (a double beep should be heard).
Step 3. Enter your new 6 digit security code followed by #47 (a double beep should be heard).

Important: It is recommended that the factory set security code be changed. This number should be written down
and stored in a safe place.
Note: While programming, if no Touch Tones are entered for 20 seconds, the RAD-1 will disconnect.
3.

B. Programming and Remote Access Features (requires a Touch Tone phone)
If a valid Touch Tone sequence is entered while programming, a double beep will be heard. Three beeps indicate an
error. To begin programming, call the RAD-1. When the device answers, you have 20 seconds to enter ✱ followed by
your 6 digit security code (a double beep should be heard). The RAD-1 may now be programmed.
Note: While programming, if no Touch Tones are entered for 20 seconds, the RAD-1 will disconnect.

Operation
The RAD-1 allows remote access to loop start C.O. lines, analog PABX stations or any other 600 ohm audio device. This
can be very useful for many applications including using a local line to access an inexpensive WATS line (line extending),
utilizing your PABX/KSU features (DISA), service observing with Viking’s SO-24A, or remote access to paging systems.
Important: It is crucial that the installer and system owner understands the functions and capabilities of both the RAD-1
and the lines and/or PABX stations connected to the RAD-1, 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 in which
the RAD-1 is put into. 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-1 toll restriction is not adequate.

A. Access
The RAD-1 will answer an incoming call on the first ring. The RAD-1 offers either unsecured access, or two levels of
secured access, designated “Priority 1” and “Priority 2.” “Priority 1” access may be used in applications where the RAD1’s outbound line is either a CO line or a PABX extension, whereas the “Priority 2” access mode is specific to applications where the RAD-1’s outbound line is a PABX extension.
Note: The “Priority 1” and “Priority 2” access codes can work well together. As an example, one group of users can be
given the “Priority 2” access code, and hence only have the ability to dial within the PABX system. Another group of
trusted users (supervisors, for example) could be given the “Priority 1” access code, and thus have unrestricted remote
access to the PABX system, including outbound dialing.
1. Unsecured Access
If neither the “Priority 1”, nor the “Priority 2” access codes have been programmed, the unit is “Unsecured.” In this
mode, the RAD-1 answers the inbound call, double beeps, bridges the lines together, and the caller is given full and
immediate access to the outbound line. The caller may then dial un-restricted phone numbers. Anybody that calls
into the RAD-1 is given an extended line.
2. Priority 1 (unlimited) Access
When a “Priority 1” access code has been programmed, the RAD-1 answers the inbound call and prompts the caller
with a single beep. The caller is then required to enter a 6 digit access code. If the proper access code is not entered
within 20 seconds, the RAD-1 will triple beep and hang up. When a valid access code has been entered, the RAD1 will double beep and bridge the lines together providing access to the opposite line port. Anybody that calls into
the RAD-1 and successfully dials the “Priority 1” access code has unlimited access to the extended line, and may
dial un-restricted phone numbers.
3. Priority 2 (limited) Access
This mode is specific to PABX applications. When a “Priority 2” access code has been programmed, the RAD-1
answers the inbound call and prompts the caller with a single beep. The caller is then required to enter a 6 digit
access code. If the proper access code is not entered within 20 seconds, the RAD-1 will triple beep and hang up.
When a valid “Priority 2” access code has been entered, the RAD-1 will double beep and bridge the lines together
providing access to the opposite line port. The caller is then given limited access, and may only dial extensions and
features within the PABX. If the caller attempts to dial the PABX outside line number (programmable, but typically
a 9) to place a call outside of the PABX, the caller will hear a triple beep and be immediately disconnected. This
effectively prevents toll fraud and system abuse. Important: If the PABX utilizes any special direct trunk access
codes in addition to the outside line number, the RAD-1 can not prevent toll fraud and system abuse on a “Priority
2” access call.
5.

When the LINE OUT relay has been actuated, several other commands can be used. For a 500ms hookswitch flash on the
LINE OUT port, dial #1. To create a 2 second disconnect on the LINE OUT port for making a new call, dial #2. To disconnect the RAD-1, dial #7. The RAD-1 will also disconnect when a CPC break occurs on the LINE IN port or after the call
timer has expired. When disconnecting, both LINE IN and LINE OUT relays are opened.
The SO-24A mode is useful when using the RAD-1 with other devices that use Touch Tone commands in their operation,
such as the Viking’s SO-24A. In this mode, the RAD-1 will only accept the #7 hang-up command. All toll restriction funcNeed More Information on the SO-24A?
tions are disabled.

Call (715) 386-4345 and select 690.

Note: For applications where an audio decibel loss is a problem, the RAD-AMP is suggested.

Other Products
DVA-2WA Digital Voice Announcer with Amplifier
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.

PA-2A Paging/Loud Ringing Amplifier 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 C.O.
line input of nearly any phone system. The PA-2A will also generate an adjustable
loud warble from up to 6 C.O. lines or from a dry contact closure. 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.
