• Status LED turns on when the unit is active and
brightens to indicate the presence of audio
• Programmable 6 digit security code
• Programmable 6 digit access code
• Two programmable levels of access
• Programmable toll restriction
• Allows 1-8XX and 911 calls
• Separate 600 ohm audio and telephone line outputs
• Disconnects on CPC, call time out, silence time out,
busy or by dialing #7
• Programmable 2 hour call timer
• Programmable 1-99 second silence timer
• Alternate screw terminal connection for phone line out
• Provides a 500ms hookswitch flash to access features on
PABX, Centrex or C.O. lines
• Provides a 2 second disconnect for new calls
• Connects phone line to the 600 ohm input/output of one-
way paging amplifiers, digital announcers and other audio
programs
• Relay contacts available for systems that need a dry con-
tact closure (activate whenever the unit’s output is active)
• Non-volatile memory (no batteries required)
The RAD-1A, 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 program-
mable toll restriction, the RAD-1A provides the security
required to help prevent phone system and toll abuse.
The RAD-1A answers on the first ring and disconnects on
CPC, call time out, silence time out or by dialing #7.
Separate 600 ohm audio and telephone line outputs are
provided, allowing connection to audio amplifiers, digital
announcers, telephone lines or analog PABX extensions.
For “line extender” applications, the user does not have to
hang up and redial the RAD-1A to make another call. The RAD-1A will also provide a hookswitch flash
on the telephone line out ports to access PABX, Centrex or Electronic Key system features.

The security code allows the user/installer to program the RAD-1A. The factory set security code is 845464 (V-I-K-I-
N-G). It is recommended that the factory security code be changed. Example: To store 123456 as the security code:
Enter Your Security Code Here:
#47
Step 1. Access programming as shown in Programming section A.
Step 2. Enter 123456 #47.
Step 3. Hang-up.
Note: The security code must be 6 digits and cannot include a , or a #.

A. Accessing the Programming Mode
?
The RAD-1A can be programmed from any Touch Tone phone using a C.O. line, analog PABX/KSU station, or a DLE-
200B Line Simulator.
Step 1. From a Touch Tone phone, call the line attached to the RAD-1A’s PHONE LINE IN jack.
Step 2. When the RAD-1A answers, enter ,, plus the 6-digit security code (factory set to 845464, see section B). A
double beep should then be heard indicating you have entered the programming mode.

D. 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-1A. When the RAD-1A answers, you have 20 seconds to enter ,followed
by your 6 digit security code (a double beep should be heard). The RAD-1A may now be programmed. Note: While
programming, if no Touch Tones are entered for 20 seconds, the RAD-1A will give 3 beeps and disconnect.

The RAD-1A 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-1A
and the lines and/or PABX stations connected to the RAD-1A, so that any and all toll fraud and other system abuse possi-
bilities are understood. This enables the installer and owner to make risk managing decisions about the system in which
the RAD-1A is put into. Viking Electronics Inc. is not able to assume responsibility since it is a function of the entire sys-
tem 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.
The RAD-1A will answer an incoming call on the first ring. The RAD-1A 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 RAD-
1A’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-1A’s outbound line is a PABX extension.
If neither the “Priority 1”, nor the “Priority 2” access codes have been programmed, the unit is “Unsecured.” In this
mode, the RAD-1A answers the inbound call, double beeps, bridges the lines together, and the caller is given full and
immediate access to the outbound line port. Anybody that calls into the RAD-1A is given unlimited access to the
extended line and may dial unrestricted phone numbers.
When a “Priority 1” 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 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 and bridge the lines together providing access to the outbound line port. Anybody that calls into
the RAD-1A and successfully dials the “Priority 1” access code has unlimited access to the extended line and may dial
unrestricted phone numbers.
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 trust-
ed 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.
This mode is specific to PABX applications. When a “Priority 2” 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 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 “Priority 2” access code has been entered, the RAD-1A will double beep and bridge the lines together providing
access to the outbound line port. If the caller attempts to dial the PABX outside line number (programmable, but typi-
cally a 9) to place a call outside of the PABX, the caller will hear a triple beep and be immediately disconnected. If no
outside line access number is programmed, then toll restrict selections are used. 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-1A can not prevent toll fraud and system abuse on a “Priority 2” access call.

When the unit’s output has been accessed, several other commands can be used. For a 500ms hookswitch flash on the
PHONE LINE OUT port, dial #1 (##1 with DIP switch 2 ON). To create a 2 second disconnect on the PHONE LINE OUT
port for making a new call, dial #2 (##2 with DIP switch 2 ON). To disconnect the RAD-1A, dial #7 (##7 with DIP switch 2
ON). The RAD-1A will also disconnect when a CPC break occurs on the PHONE LINE IN port, after the call timer has
expired, or after the silence timer has expired.
The SO-24A mode is useful when using the RAD-1A with other devices that use Touch Tone commands in their operation,
such as the Viking’s SO-24A. In this mode, the RAD-1A will only accept the #7 (##7 with DIP switch 2 ON) hang-up com-
mand. All other toll restriction functions are disabled.
Note: For applications where an audio decibel loss is a problem, the RAD-AMP is suggested.
