A. Legacy Mode
If the RC-2A is programmed to answer a ringing line, it will answer after the selected ring delay. A single acknowl-
edgement tone will be heard, signaling the user that the RC-2A has answered the line. If a security access code has
been programmed (no code switches set to D), a touch-tone "," plus the security access code may be entered at this
time and a second acknowledgement tone will be heard. After this acknowledgement tone, the built in 2 digit relay com-
mands can be dialed (see page 5, C. Relay Activation Codes). If "," plus an incorrect security access code is entered,
the RC-2A will immediately disconnect (hang-up). To prevent unauthorized use, if a user dials "," plus an incorrect
security access code on 5 consecutive incoming calls, the unit will disconnect and not answer the line for 60 minutes.
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 relay activation (opening or closing a relay contact) remotely via DTMF Touch Tone input over
a standard analog C.O. line or PABX/KSU station. When the correct relay activation code is entered, the RC-2A acti-
vates its relay contacts on the terminal strip followed by an acknowledgement tone.
Step 1
Step 2
Step 3
Step 4
Step 5
Call the RC-2A using a Touch Tone phone.
When the RC-2A answers, a single beep (acknowledgement tone) will be heard.
If the security access code has been disabled (one or more code switches set to D), go to step 4. If a security
access code has been set (no code switches set to D), enter "
," followed by your 3 digit security access code
(see page 4, A. Security Access Code).
Enter a two digit relay activation code (see page 5, C. Relay Activation Codes). A single or double beep
(acknowledgement tone) should be heard
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.
1. Accessing the RC-2A Remotely
Step 1
Step 2
Step 3
Step 4
Establish voice connection with the RC-2A by accessing the doorbox or dedicated line.
If the security access code has been disabled (one or more code switches set to D), go to step 3. If a security
access has been set (no code switches set to D), enter "," followed by your 3 digit security access code (see
page 4, A. Security Access Code).
Enter a two digit relay activation code (see page 5, C. Relay Activation Codes). A single or double beep
(acknowledgement tone) should be heard.
If a security code has been set (no code switches set to D), enter "8" or "18" before hanging up to place the RC-
2A back into secure mode. Alternatively, the unit will automatically return to the secure mode if no Touch Tones
are detected for 60 seconds.
2. Accessing the RC-2A Locally
B. Alternative Mode
If the RC-2A is programmed to answer a ringing line, it will do so after the selected ring delay. A single or double
acknowledgement tone will be heard, signaling the user that the RC-2A has answered the line. After this acknowl-
edgement tone, the one, two or three digit relay activation code can be dialed and a second acknowledgement tone
will be heard. The relay activation code is programmed by the setting of the code switches (see pages 5-6, B. Entry
Code Switches). If the RC-2A is not programmed to answer the line, it can passively monitor a communication path
for the proper activation code.
The RC-2A provides a relay activation (opening or closing a relay contact) remotely via DTMF Touch Tone input over
a standard analog C.O. line or PBX/KSU station. When the correct relay activation code is entered, the RC-2A acti-
vates it's relay contacts on the terminal strip followed by a single beep as an acknowledgement tone.
Only "timed" relay activation is possible in the Alternative mode. When the relay activation code is dialed, the timing
of the relay contacts depends on the setting of DIP switches 1-4 (see page 6, C. DIP Switch Settings). If the RC-2A
is accessed remotely and there is a relay activation 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 relay activation to con-
tinue or start the relay activation over again by entering the relay activation code.
