to activate command channel 10’s A switch (or an additional “#” can be
entered to activate command channel 10’s B switch) after accessing status
channel 8 with the “7 0 8 *”.
Step 7 — Sign Off
Sign off from the VRC2000 by entering the following code:
☎ “9 9 9”
The VRC2000 will respond:
• GOOD-BYE
Then the unit will automatically hang up the telephone line.
HANG-UP NOTE:
The VRC2000 will also automatically hang up if no codes are entered for a
period of five minutes (if the inactivity timer is enabled).
Remembering VRC2000 Codes
The codes for status, metering, and command channels correspond to the
letters that are etched into the number keys of a standard DTMF telephone
(Figure 23, left).
Thus, command corresponds with 2, metering corresponds with 6, and status
corresponds with 7.
Alarms
The VRC2000 saves the most recent 32 alarms and reports them to you.
Alarms can be cleared at any time and, of course, commands can be issued
to the VRC2000 to correct the condition which caused the alarm. There are
four types of alarms: unauthorized access, status channel, metering channel
and metering-system failure.
Unauthorized Access
An alarm condition will be activated by three attempted unauthorized
accesses. In other words, if anyone attempts to enter an incorrect access
code three time in a row, the VRC2000 will report that an anauthorized
person is attempting to gain access to the site. If such an alarm occurs,
Gentner Communications recommends changing access codes as a safety
measure.
Status Channel
Each status channel can be programmed to cause an alarm condition when it
changes its state.
Metering Channel
Each metering channel can trigger an alarm from any one of four tolerance
limits.
Metering-System Failure
A metering-system failure alarm will be generated if any status or metering-
channel input is overloaded.
