be programmed to cause an alarm condition. The VRC2000 can also be
programmed to turn on a set of auxiliary lights if the main set failed.
CHANNEL OVERLOAD NOTE:
Be very careful not to overload status channels with excessive voltage or current.
Overloads can seriously damage the VRC2000. For status-channel electrical
specifications, see Specifications (Page 90).
Alarm Delay
There is an alarm delay built into each status channel. The amount of time
that will pass between when a status channel changes states (from high to
low, or vice versa) and when an alarm condition is activated is user-
programmable. The alarm delay can be anywhere from one to 99 seconds.
Always use two digits when programming this parameter.
Preparation for Programming
Because each status channel has many functions and options, setting up
status channels will take some time. To speed up the process, it is important
to plot out the site parameters to be monitored with the status channels
before beginning to program the VRC2000. When doing this, be sure to
decide if the parameter being monitored should cause an alarm, and if the
VRC2000 should automatically take some action when the a status-channel
state changes.
Status Channel Programming
The VRC2000 can access set-up information about a particular status
channel. When this is done, the unit will list functions available for the
status channel.
For each parameter of the 10 status-channel parameters, the VRC2000 will
respond with a preprogrammed message, followed by the default parameter,
followed by a [BEEP].
To begin, enter
☎ “7 0 1”
The VRC2000 will respond with the following 10 phrases:
• CHANNEL IDENTIFIER FOR STATUS CHANNEL ONE IS ... {5 MILLISECONDS SILENCE,
5 MILLISECONDS SILENCE} ... [BEEP]
STATUS CHANNEL IDENTIFIER NOTE:
Two words from the VRC2000 word list (See Appendix I: Word List, Page 125.)
for the unit to use as a status-channel identifier. The default setting for each
status channel is two five-millisecond silences. Silences do count as words.
• DEFAULT COMMAND CHANNEL FOR STATUS CHANNEL ONE IS ... {DISABLED} ...
[BEEP]
STATUS-COMMAND CHANNEL ASSOCIATION NOTE:
A status channel can be associated with a command channel. This will allow
control of the selected command channel directly after requesting information
about a status channel. The default setting {Disabled} indicates that this status
channel is not associated with any command channel.
