Indications of current alarm classesexisting in the various maintenance subsystems are displayed on the MAPworkstation. Usually only critical and major alarm classes activate visual oraudible alarm devices.The alarm class is also printed on any log message concerning maintenanceoccurrences. If no alarm is associated with the log, the "information only"classification is printed.The alarm system can also be affected by commands given as input at theMAP workstation. For example, the SIL command can be input to silence anaudible alarm while troubleshooting is in progress.Log systemThe log system records and prints messages concerningmaintenance-related events. As output reports are generated, they arestored in the Meridian SL-100 log system in log buffers. Each subsystemhas a log buffer dedicated to it.
