Interpreting the
LAC Alarm
Reports
This section describes how to interpret the LACSUM and LACALM reports at the
MSC. The following alarm descriptions are intended as a guide for determining
possible causes and corrective actions for LAC alarms, to the greatest extent
possible, from the MSC. Knowledge of the detailed troubleshooting procedures in
paragraph D is assumed. It is also important to understand the differences in how
A/B-Series and C-Series LACs report alarms, as described in paragraph F.
Additional technical details of the LAC alarm detection and reporting system are
also included in paragraph G.
NOTE:
Be sure that the line of "equals" signs is printed out at the bottom of the
LACSUM report. This line indicates that the hourly update has been
completed. If this line is not present, the file was printed in the middle of the
update and is not complete. Reprint the file.
