The Rule Bilge Alarm Kit consists of a Rule "Plus" float switch with debris guard and an in-dash gauge that features a visual and 85 decibel audible alarm to warn of pump system failure.
The float switch should be mounted in the bilge just above the existing pump system float switch and will activate if water rises to that level due to the failure of the pump system. The Rule bilge alarm kit allows an unmanned compartment to be constantly monitored.
For additional compartments, add another float switch.
