Re: Battery alarm while moored.
All panel breakers were OFF.... including the fridge breaker.
Nothing on the boat had electricity yet the battery voltage dropped enough to cause the voltage alarm to sound.
Often essential equipment, like bilge pumps, will be wired directly to the house battery bank - not via the breaker panel.
It could be that the house battery is on it's last legs and the bilge pump is telling you.
Like others have already suggested, you'll need to get out a multimeter and find out. Good luck!
