If the RC-2A is programmed to answer a ringing line (DIP switch 7 ON), 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 acknowledgement tone, the one, two or three digit relay activation code can be dialed and a second ac-
knowledgement tone will be heard. The relay activation code is programmed by the setting of the code switches
(see page 5, B. Entry Code Switches). If the RC-2A is not programmed to answer the line (DIP switch 7 OFF),
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 provides a single beep as an acknowledgement tone and activates its relay contacts on the terminal strip.
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 continue or start the relay activation over again by entering the relay activation code.

2. Accessing the RC-2A Locally
Step 1. Establish voice connection with the RC-2A by accessing the doorbox or dedicated line.
Step 2.
If the security access code has been disabled (one or more code switches set to D), go to step 3. If a security ac-
cess code has been set (no code switches set to D), enter "Q" followed by your 3 digit security access code (see
page 3, A. Security Access Code).
Step 3.
Enter a two digit relay activation code (see page 5, C. Relay Activation Codes). A single or double beep (ac-
knowledgement tone) should be heard.
Step 4.
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
Step 1. Establish voice connection with the RC-2A by accessing the doorbox or dedicated line.
Step 2.
Enter the one, two or three digit relay activation code (see page 5, B. Entry Code Switches). A
single beep (acknowledgement tone) should be heard.
1. Accessing the RC-2A Remotely
Step 1. Set DIP switch 7 to ON and call the RC-2A using a Touch Tone phone.
Step 2. When the RC-2A answers, a single or double beep (acknowledgement tone) will be heard.
Step 3.
Enter the one, two or three digit relay activation code (see page 5, B. Entry Code Switches). A
single beep (acknowledgement tone) should be heard.
Step 4. The unit will disconnect when no Touch Tones are detected for 60 seconds.
Step 5. Set DIP switch 7 to the desired position.
The SRC-1 enables a standard touch tone phone to securely operate a
set of timed relay contacts to control a doorstrike or gate controller at a
remote location. The SRC-1 is fully user programmable and uses non-
volatile memory. The SRC-1 eliminates the possibility of dialing the acti-
vation code through the entry phone using a hand held touch tone dialer.
The SRC-1 features a switchable 32V talk battery to allow use with any of
Viking’s entry phones (E Series), doorboxes (W Series) or hot-line/panel
phones (K Series).
The SRC-1 is installed between the entry phone and the secure phone,
and will reject touch tones from the entry phone and only operate the relay
if the correct activation code (user programmable) is given from the secure
phone.
The SRC-1 also provides up to 32 keyless entry codes to operate the relay from the entry phone with 1 to 6 digits.
This feature can be disabled in programming for increased security.
