For commercial vessels 26 feet and longer operating in US waters, CFR 182.530 requires a visual and audible alarm in each unmanned space — this system satisfies that requirement. The expandable float switch design means you can monitor multiple compartments (engine room, lazarette, forward bilge) by adding additional float switches to the same gauge, which is a cost-effective way to cover a larger vessel.
