Fireboy-Xintex G-2BB-R Marine Gasoline Detector, 2-Zone with Blower Relay

The Fireboy-Xintex G-2BB-R Marine Gasoline Detector protects your boat by proactively detecting gasoline vapor issues in the bilge and engine compartment before they become dangerous. It uses a remote sensor to monitor the bilge and engine compartment continuously, including during and after fueling, giving you an early warning of fuel vapor buildup rather than waiting for a problem to develop.

The system covers two sensor zones, so it can monitor multiple compartments on the vessel at once. When gasoline vapor is detected, the unit alerts you with both LED warning lights and a 68 dBA audible alarm, making the warning hard to miss whether you are aboard or nearby. A silence/test button lets you quiet the alarm or verify the system is functioning correctly. Built in is a 10A relay that can automatically start the bilge blower fan when vapor is detected, helping to ventilate the compartment and clear fuel vapor without requiring you to manually intervene.

The G-2BB-R runs on a 9-30 volt input range and draws power at 12VDC, making it compatible with standard marine electrical systems. This gasoline detector does not include generator shutdown functionality. It is designed for boaters who want dependable, always-on monitoring for gasoline vapor hazards in enclosed compartments.
