METERING CHANNEL ALARMS
Metering-channel alarms are generated the same way as status-
channel alarms. The second high limit for a metering channel
could be set to generate an alarm. If an alarm is generated and
cleared, a new alarm will not be generated until the metering-
channel’s sample returns to the metering-channel’s nominal
range and then rises to above the second high limit. Once again,
the alarm is generated by the transition over the tolerance limit.
REMEMBERING VRC2500 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.
Thus, c
ommand corresponds with 2, metering corresponds with
6, and s
tatus corresponds with 7.
MUTING OUTBOUND TELEPHONE NUMBERS
The VRC2500 can be prevented from calling alarms to an
outbound telephone number(s) by entering the following code:
 “1 0 1 *” through  “1 0 5 *”
The VRC2500 will respond:
• P
HONE NUMBER X DISABLED
This disables alarm reporting for that outbound telephone
number. To enable the outbound telephone number(s) again,
enter:
 “1 0 1 #” through  “1 0 5 #”
The VRC2500 will respond:
• P
HONE NUMBER X ENABLED
You can also disable alarm reporting to all outbound telephone
numbers can for one hour. To disable alarm reporting, enter:
 “0 3 0 *”
The VRC2500 will respond:
• A
LARM REPORTING DISABLED
