ESN100 Operation and Installation Manual
Chapter: Introduction and Specification
Alarm
There are a number of alerts available. Shallow water alarm and power failure alert are mandatory. In addi-
tion there is a Deep water alert, power reduction, system error and time synchronisation alerts.
These are sent as alarm/alert sentences on the NMEA and LAN output of ESN100-SB unit.
The recommended setup of alarms from the navigational echo sounder is that echo sounder alarms are to be
connected to CAM (Central Alarm Management). If the system fails, and there is no other system to detect
the failure, a relay is available within the JB40POW unit that should connected to an external beeper.
The ESN100 has two configurations of alarm NMEA formats available in the software setup.
ALF: Is the NMEA standard complying with IEC62923-1/2:2018 and IEC62288:2014.
ALR is the older standard and may comply with IEC61924-2:2012 and IEC62288:2014 only by connecting
the “Power failure alarm relay”in JB50E1-SA to the external CAM. If no CAM is available, a beeper must be
connected to the power failure relay in JB50E1-SA, and on “power failure” the beeper will sound.
More information about the alarm settings is available in the alarm setup part of this manual.
