Supported Alarms
Alarms can come from many sources. These include:
• The meter event log (within the meter)
• The voltage event log (within the meter)
• Diagnostic indicators (within the meter and the NIC)
• Tamper indicators (within the meter)
• Last-gasp and power-restored messaging (from the NIC)
The NIC processes alarms by logging them and storing them in one of two
messaging queues. One queue is for alarms published in real time, and the other
for alarms which are published opportunistically (i.e. at the next opportunity -
riding along with other data which is being published anyway.) Alarms have a
default priority assigned to them. Alarms which have a priority above the real time
alarm threshold (>170) are sent immediately in a dedicated alarm message. Alarms
which have a priority which fall below the opportunistic alarm threshold (≤ 85) are
discarded. Alarms between the two thresholds (85-170) are sent opportunistically.
To disable an alarm which originates in the meter, the meter must be programmed
(configured) to not generate that alarm. In this way, unwanted (nuisance) alarms
can be masked so that they are not communicated to the headend.
