Alarm Configuration
The Threshold field allows you to configure a new threshold for the alarm
highlighted in the Alarm Type list.
The Status field allows you to enable or disable the alarm highlighted in the
Alarm Type list.
Click on to save any changes you have made to an alarm before
selecting another alarm; click on to exit the window.
Setting a Ring Level Alarm
To set an alarm at the ring level:
1. In the Timebase field, enter the amount of time, in seconds, you want the
selected variable counted for comparison to your alarm thresholds.
Remember, this timebase will apply to all enabled alarms at both the ring and
station levels.
2. In the Alarm Type list, click mouse button 1 on the alarm type you wish to
configure.
3. Enter your desired alarm threshold in the Threshold field, keeping in mind
that ring-level alarms will count
all occurrences of the selected variable on the
ring as a whole.
4. Enable or Disable the selected alarm type by clicking mouse button 1 in the
appropriate Status option.
5. Click mouse button 1 on to save your changes. If you wish to
configure more than one alarm type, be sure to click on before
selecting another alarm type, or the changes you made to the first alarm will
be lost.
Your new alarm status and thresholds will take effect immediately.
Setting and Viewing Station Alarms
To view or set station-level alarms, highlight the appropriate interface in the
Ring/Stn Alarms window, then click mouse button 1 on
; the Station
Alarms window, Figure 4-3 , will appear.
NOTE
When setting thresholds for ring-level alarms, keep in mind that the TRMMIM is
counting all occurrences of the selected variable on the whole ring, not just those
occurrences on a single station. Note, too, that ring-level alarms can only be set for non-
isolating errors — that is, those that do not pinpoint a specific trouble spot on the ring.
