enough so the monitor does not trigger on unwanted Events such as nearby vehicle traffic. At the
same time, you have to set the trigger level low enough so that an Events activity exceeds the
trigger level and starts the monitor recording.
To set a trigger level, click on the Trigger Level box. Enter the new level.
ii Alarm Level (Blastmate II Only)
The alarm level controls the triggering of an optional remote alarm (711A1401).
The remote alarm sounds two alarms: warning and alarm. The warning alarm sounds when Event
activity exceeds the set Geophone trigger level. The alarm level can be set to a different level that
is higher than the trigger level of the Geophone. This allows for the triggering of a second alarm at
the higher level.
For example, in pile driving operations the remote alarm triggers a warning when activity exceeds
the trigger level for the Geophone, notifying the operator that the pile driving activity has
exceeded that set level. The second alarm triggers when activity exceeds the alarm level, set to a
higher level, notifying the operator to re−evaluate the piling operation.
To set an alarm level, click on the Alarm Level box. Enter the new level.

ii Trigger Level
The trigger level sets a threshold that must be exceeded by an Events activity before the monitor
begins recording. Use your judgment when setting a trigger level. You must set the level high
enough so the monitor does not trigger on unwanted Events such as nearby vehicle traffic. At the
same time, you have to set the trigger level low enough so that an Events activity exceeds the
trigger level and starts the monitor recording.
To set a trigger level, click on the Trigger Level text box. Enter the new level.
