Alarms Overview; Alarm Manager Overview - Lighthouse a65 Installation And Operation Instructions Manual

12.1 Alarms overview

Alarms alert you to a situation or hazard requiring
your attention, such as shallow depth or a change in
water temperature.
Alarms are triggered by system functions, and
external devices connected to the Multifunction
display (MFD).
Audible and visual warnings are displayed on all
networked MFD screens when an alarm is triggered.
The alarm message provides details of the reason
for the alarm.
Alarm messages are color coded to signify their
severity as follows:
• Red Alerts — immediate attention required due
to potential or immediate danger to life or vessel.
Red Alerts continue to sound until acknowledged
or the conditions that triggered the alarm are no
longer present. Red Alerts are accompanied by
an urgent audible tone.
• Orange Warnings — used to warn a user about a
change in situation that they need to be aware of.
Orange Warnings are accompanied by a normal
audible tone.
• Blue Cautions — used to inform a user of any
other information. Blue Alerts are also used for
user acknowledgments and disclaimers. Blue
Alerts are not accompanied by an audible tone.
Acknowledging an active alarm
When an alarm event occurs it can be acknowledged
by selecting Ok, this will dismiss the alarm message
and stop the alarm tone.
During an active alarm event (i.e. an alarm message
is displayed):
1. Select Ok.
The message is dismissed and the alarm tone
is stopped.
Tip If an alarm message includes an Edit button
then the alarm's settings can be accessed directly
from the alarm message.
Most alarms will remain active until the conditions
that triggered the alarm are no longer present e.g. a
Shallow Depth alarm will automatically dismiss when
the depth becomes deeper. Whilst active the alarm
will be triggered at a set time interval.
