RC-2A
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

programmable access code can also be programmed to prevent unauthorized usage.
The RC-2A will then allow remote relay operation.

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.
