Are you using the existing bilge pump
level sensors or adding in extra ones?
Does your vessel currently have an audible bilge alarm
connected to existing bilge pump
The reason I ask is because on my 2013 L450F the alarm and pump
control wires are already wired up to switches up at the helm
. An easy point to connect to if this works for you.
While doing this if you do not have already, a visual indication (Led) of which alarm Port/Starboard is going off is also a very useful addition.
1) from the port hull through to the main switch panel in the salon.
Access via the aft cupboard with fresh water pump
in it, use a fiberglas wire running fish
tape to get across under the Main cabin
floor to switch panel in the salon.
2) from the starboard hull through to the main switch panel in the salon.
From under floor up into electrical
distribution cupboard to aft of doorway down intocabin, then straight up into switch panel in the salon.
3) from the motion sensor (near the chart table) through to the main switch panel in the salon.
If it mounted on chart table: across the boat
behind Couch below the front windows, accessible in starboard hull through the back of the cupboard (owners version) then under floor aft, then same as bilge alarm to the main switch panel in the salon.
If it mounted above chart table on ceiling: Then you need to start removing ceiling panels
a much bigger job.
