sonusAlarmOutAdmnValue is a read-write INTEGER (clear or alarm) giving the default value for this relay, though the MIB notes only alarm contact five can be manually reconfigured — contacts 1 through 4 have a fixed default of clear that cannot be changed. Admins use this to manually force relay five into an alarm or clear state independent of system-triggered events, since the other four contacts are locked to clear as their default. For example, an admin testing the alarm panel wiring might set sonusAlarmOutAdmnValue to alarm(2) on relay five to manually trigger it, since that's the only relay where this default is user-configurable.
