Echosounder “Shallow water” alarm is a safety critical alarm and should be configured such that
the user must view the echogram screen to acknowledge a shallow water alarm. This is so that
the history of the water getting shallower is seen.
“Shallow water” is classed as a category A alarm. On a single channel ESN100 the shallow
alarm will be triggered when the depth goes from deeper area, passes the alarm limit, on the
active transducer.
If the system is part of an approved INS system with the capability of showing the echogram
on other devices, then the system can be classed as Category B. This allows the Alarm to be
acknowledged from that system. Responsibility transfer of this alarm will only be available in the
CAT B mode.
The system has an internal alarm sounder, that can be disabled for CAT B usage on the display
menu.
There are three levels of alerts:
The ESN100 can be made to handle alerts using the ALR/ACK protocol or the ALF/ACN/ALC
Protocol.
The Protocol is selected on the config – Alert setup page
