[CA] [CA11] Low voltage alarm

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Peter,

Unfortunately, the LightHouse 3 Alarms settings (HOME->ALARMS) does not include a configuration setting to set a threshold for the low voltage alarm, nor does it include a option to switch off the Low Voltage Alarm. Within the MFD's Fishfinder application, a dialog will pop up to report "Sounder supply voltage too low" when the voltage level to the MFD drops below 10.8V. No audible alarm is produced as a result of this condition. Low voltage alarms can also come from the engine system if it has been interfaced to the marine electronic system's NMEA 2000 backbone and the engine system or gateway report an engine system low voltage alarm. The latter alarms may be switched ON/OFF by configuring Engine Alarms (HOME->ALARMS->SETTINGS->ENGINE ALARMS) to OFF. In the case of the latter, it would be recommended that data from the engine system and gateway be inspected to determine why this alarm has been generated.
