Remote Touch
Tone Controller
April 18, 2001
The RC-2A Remote Controller provides
remote relay operation from any standard
Touch Tone telephone.
The controller is designed to be installed
either locally or remotely. For local installations the RC-2A can be installed in series
on any analog communications path, such
as analog C.O. lines, analog PABX/KSU
stations or Viking’s W-Series Doorboxes.
and will passively monitor for Touch Tone
commands.
For off-premise applications, the RC-2A will

A. Security Access Code
Note: An access code should be used, when the RC-2A is used on a line with other equipment that may dial.
1. Setting the Access Code
The RC-2A contains (3) rotary access code switches (see diagram above). Using a small flat blade screwdriver,
rotate the white arrow on each switch to the desired access code setting. The code may be any digit 0-9 or “C” (#
on a Touch Tone pad). Note: For extreme security applications, a special telephone with a 4 x 4 keypad may be
used (Fax Back Document 855).
2. Disabling the Access Code
If any rotary access code switch is set to position “D” the access code is disabled. In this case, any call to the
RC-2A will have immediate access to activation codes (see section D). Note: When the access code is disabled,
the setting of DIP switch 3 has no effect (unlimited closures allowed).

Switch 1: Latch Commands
If this DIP switch is in the ON position, the relay will not be able to be latched (maintained) and command codes 10
and 19 will be ignored.
Switch 2: Ring Delay
The RC-2A answers on the fifteenth ring by default. This can be changed to the first, second or sixth ring by
following the instructions above.
Switch 3: Closure Limitations
If this DIP switch is placed in the ON position, only one closure will be allowed during the access.
Important: The RC-2A ships by default in the Legacy Programming mode. Optional programming is also available (see
Alternative Programming). The alternative programming mode dramatically changes the programming and operation of
the RC-2A. Use only the programming features described in the respective sections for the programming mode you
choose.
B. Entry Code Switches
The blue access code switches set the relay activation code. This code can make use of any
of the digits available on the rotary switches, as long as the user is aware that D and E can
only be entered using a special 4x4 keypad. Note: For more information on using the RC-
2A with a special 4x4 keypad, retrieve Fax Back Document 855.

1. Single Digit Relay Activation Code
To program a single digit relay activation code, set any two of the three code
switches to F. Example: FF3 (shown right).
2. Two-Digit Relay Activation Code
To program a two-digit relay activation code, set any of the code switches
to F. The other two switch settings comprise the relay activation code.
Example: F47 (shown right).
3. Special Character Relay Activation Code
To program the relay activation code to be ✱ or #, set all three code switch-
es to F (shown right). In this case, either a ✱ or # will activate the relay.
4. Ring Delay
To program the ring delay to 2 instead of the normal 15, set at least one of
the code switches to B or C (shown right). Example: FFB = “✱” as the
activation code and 2 as the ring delay.

A. Accessing the RC-2A Remotely
1. Call the RC-2A using a Touch Tone phone.
2. When the RC-2A answers, a single beep will be heard.
3. If no access code was set, go to step 4. If an access code was set, enter “✱” followed by your access code.
4. Enter a one, two or three digit relay activation code (see Legacy or Alternative Programming section). An
acknowledgement tone should be heard.
5. Enter “8” or “18” before hanging up to force the RC-2A to release the line. Alternatively, the unit will disconnect if
no Touch Tones are detected for 60 seconds.
B. Accessing the RC-2A Locally
1. Establish voice connection with the RC-2A by accessing the doorbox or dedicated line.
2. If no access code was set, go to step 3. If an access code was set, enter “✱” followed by your access code.
3. Enter a one, two or three digit relay activation code (see Legacy or Alternative Programming section). An
acknowledgement tone should be heard.
4. If an access code was set, enter “8” before hanging up to place the RC-2A back into secure mode. Alternatively,
the unit will disconnect if no Touch Tones are detected for 60 seconds.

If the RC-2A is programmed to answer a ringing line, it will do so after the selected ring delay. A single acknowledgement
tone will be heard, signaling the user that the RC-2A has answered the line. If a security code has been programmed, it
may be entered at this time and a second confirmation tone will be heard. If the RC-2A is not programmed to answer the
line, it can passively monitor a communication path for the proper access and/or activation code.
The RC-2A provides a contact closure (normally open contacts) remotely via DTMF Touch Tone input over a standard analog C.O. line or P ABX/KSU station. When the correct relay activation code is entered, the RC-2A produces a closure at the
terminal strip followed by a single beep as an acknowledgement tone. If the RC-2A is accessed remotely and there is a
closure already in progress, the RC-2A indicates this by producing two beeps instead of a single beep when it answers. At
this point the user may allow the existing closure to continue or start the closure over again by entering the relay activation
code.
