RFC-1 Basic Operation page 5.1
Section 5 — Basic Operation
5.1 Overview
The primary function of the RFC-1 is to monitor and control outboard devices. To perform these functions, a user
connects to the RFC-1 with a telephone. The telephone can be directly connected or through a telephone line. The
user issues two-digit commands with the telephone keypad. The RFC-1 responds with a synthesized voice.
The RFC-1 is controlled with the tones generated by a typical telephone keypad. Rotary phones do not work.
RFC-1 installations can be simple or as complex as is reasonably necessary depending on the site requirements.
The system is capable of answering calls, taking basic telemetry readings and performing manual control activity
immediately on installation. Even non-technical users can take readings and perform basic control operations. With a
few adjustments, basic monitoring activities with telephone alarms can be enabled.
The RFC-1 can also serve more demanding installations requiring automatic power and/or pattern changes. With
appropriate hardware accessories, the system can perform sophisticated monitoring activities with optional data
communications. These more advanced features are described in Section 6 of this document.
Information in this section is based on the original factory programming. Portions of this chapter may not be accurate
if changes have already been made to the system.
5.2 Operation from the Local Telephone
The system can be operated from a telephone that is connected directly to the RFC-1 at the jack labeled "Phone".
This telephone is referred to as the “local phone”. Users control the RFC-1 by entering commands with the keypad of
the local phone. The command codes are described later in this document.
5.2.1 Connecting to the RFC-1
Operation from the local phone is initiated by pushing the button labeled "Local Control" on the RP-8 relay panel.
When the button is pressed, the RFC-1 activates the local phone and speaks the identification phrase "This is RFC-
1/B". No security code is needed to access the system from the local phone. The system activates immediately and
awaits commands. This state of operation is referred to as the “operating mode”.
As a security precaution, the RFC-1 will not remain active indefinitely. After 2.5 minutes of inactivity the RFC-1 will
release the local phone. Press the local control button to re-activate the RFC-1.
5.2.2 Selecting a Channel
To select a channel, simply enter the two-digit channel number on the telephone keypad while the system is in
operating mode. It is important to use two digits. Enter a leading zero for channels with less than two digits.
Channel numbers start at 00 and continue through 63 depending on how many relay panels are installed. Both digits
must be entered within 5 seconds of one another.
Only one channel can be selected at a time. A channel remains selected until any of the following occur:
• Another channel is selected
• A programming command is entered
• The user hangs up and/or the system disconnects
A channel must be selected to take readings or operate control relays.
