Definition
Disturbance
Disturbance is a detected and localized mechanical motion or vibration in the
protected area.
Event
When the total amount of disturbance within the specified limits of location and
time exceeds the event threshold, the disturbance is declared to be an event.
In Progress
An event remains in progress as long as the disturbance continues within a
specified distance of the event location. The attributes of the event, including
the event location, may be updated while the event is in progress. There may be
more than one event in progress at different locations at the same time.
Complete
An event expires and becomes complete if the disturbance stops for a period
longer than the event life time. If the disturbance resumes at the same location,
it may be declared a new event.
Alarm
An alarm is a notification of an event, either in progress or complete. An alarm is
generated for each event, once the event is declared (one event = one alarm).
Time of Alarm
The date and time the alarm was generated. The alarm time may differ from the
time the disturbance began.
Current Alarms
An alarm remains current and is reported until the alarm is acknowledged or the
system is disarmed. (The event may be in progress or complete.)
Clear Alarm
(Acknowledge)
An alarm is cleared (acknowledged) by an operator’s action. The operator must
perform all actions defined by the facility’s alarm handling procedures before
clearing the alarm. A cleared alarm is removed from the current alarms list and
is no longer reported. If the event remains in progress, it can generate a new
alarm, which will then be reported.
Event Location
The average location of the disturbance which caused the event. The event
location is refined while the event is in progress.
Event Duration
The length of time between the beginning and the end of the disturbance.
Event Level
The cumulative amount of disturbance over the event duration.
