12.5.3 Secondary TM Alarm Acknowledged
On acknowledging the Secondary TM alarm, the Secondary TM will resume communications with
the Primary TM resulting in the acknowledged ‘Duplication’ alarm on the Primary TM ceasing.
From that point on, it will not be automatically apparent, that the original alarm on the Secondary
TM has cleared. For example, if the original problem at the Secondary TM was loss of GPS signal
(‘PPS’ fail), once this alarm is acknowledged, the return of the GPS signal will not be notified, i.e. it
will be necessary to log back into to the Secondary TM at intervals to check if the problem is still
present or has cleared. Once the original alarm has been acknowledged on the Secondary TM,
the occurrence of any other alarm or re-occurrence of the same alarm will be notified as described
above.
