Figure 263 – Trigger Configuration Editor – Tripped Alert
Re-trigger Period – When you accept an alert, it will change to the “Accepted” state, and
annunciators that are sounding for that alert will stop sounding. If the condition which caused
the alert remains true after the amount of time in this field, the alert will return to the “Active”
state, and annunciators will begin sounding again for that alert. If a value of 0:00 is entered,
then the alert will never re-trigger.
Alert Set Delay – If the switch being monitored is in the Tripped state for the amount of time
specified in this field, the alert will become active.
Alert Clear Delay – If the switch being monitored is in a state other than “Tripped” for the amount
of time specified in this field, the alert will become inactive.
8.3.7.7 Trigger Type is Outside Radius Alert
The Outside Radius Alert is used to signal an alert whenever the vessel moves outside a
programmable distance in any direction away from a reference point (expressed as a longitude and
latitude). This alert is useful when the vessel is anchored or moored and the vessel should not drift
outside a perimeter and if it does, an alert is activated. The point of reference can be selected from
the current position or it can be manually entered. Figure 264 shows an Outside Radius Alert and
associated parameters. The Outside Radius Alert and the Anchor Alert are very similar. The radius of
the Outside Radius Alert is specified in either Nautical Miles or Kilometers, while the radius of the
Anchor Alert is specified in Feet or Meters.
