General Information
WARNING
GASOLINE FUME DETECTORS ARE MEANT TO SERVE AS A SUPPLEMENTAL WARNING SYSTEM. IT
IS NOT MEANT TO REPLACE STANDARD SAFETY PRACTICES WHICH SHOULD BE CARRIED OUT
AROUND EXPLOSIVE GASES.
The G-1BB-R, G-1CB-R, and G-2BB-R Gasoline Fume Detectors are an effective means to monitor
gasoline fumes in an engine compartments, leaking fuel tanks, or fumes from un-burnt
hydrocarbons emitted from faulty exhaust systems. In addition, these units automatically actuate
your bilge Blower to purge the space of fumes. The systems use sensors, located in a place of
interest, and a central display unit that notifies you of the state of the system.

Operation of Xintex Gasoline Fume Detector(s)
There are 3 LEDs located on the Display Unit for each channel on the system, as well as an LED for
the Blower status. The Green LED, located at the top, indicates that the system is operational.
The Yellow LED, located in the center, indicates that there is a Fault in the system. This is to notify
the user to check the connections and wire runs of the sensors. There may be a break in the
wiring or a disconnected sensor on that channel. The Red LED, located at the bottom, indicates a
fume buildup of 20% of the LEL (Lower Explosive Limit) which is considered an alarm. The Blower
status LED and alarm horn will actuate when the Red LED is illuminated. Whenever the Blower
status LED is illuminated, the Blower is active.
The alarm status will continue as long as the fume level remains at an elevated level. The alarm
horn may be silenced by pressing the “Check/Reset” button, but the Blower will remain active
until the alarm status has ended. The alarm will reactivate after 30 seconds as long as the
Detector remains in alarm status. The problem should never be considered corrected as long as
the Red LED is illuminated.

Installation
Installing the Display Unit (G1BR-B01-D/G1CR-B01-D or G2BS-B01-D)
The Display Unit should be located at the instrument panel, so that the visible and audible
indicators may be easily observed.
Drill a 2-1/16” hole to accommodate the G1BR-B01-D/G1CR-B01-D Display Unit.
Drill a 2-1/8” hole to accommodate the G2BS-B01-D Display Unit.
Insert Display Unit into hole and secure with the provided threaded mounting nut. A Trim Ring is
available if needed.
NOTE
DO NOT MAKE ELECTRICAL CONNECTIONS AT THIS TIME. THEY WILL BE ADDRESSED IN A LATER
SECTION.
Routing Sensor Cable(s) (FS-X01 CABLE XX’)
A 20 FT Sensor Cable is provided for each Gasoline Fume Sensor. The Sensor Cables should be
routed starting at the Display Unit, then to the pre-determined location of the Gasoline Fume
Sensor. Connect to the Display Unit using the attached quick-disconnect connectors. Take care
not to pinch, break, or cut the Sensor Cable or put too much stress on the connectors while
routing the cable. Secure the Sensor Cable with the appropriate hardware for the application.
NOTE
DO NOT CUT EXTENSION CABLE FOR ANY PURPOSE. DOING SO VOIDS THE PRODUCTS
WARRANTY. LONGER CABLES ARE AVAILABLE FROM 20 FT TO 100 FT.
Installing Gasoline Fume Sensor(s) (FS-T01)
The Gasoline Fume Sensor should be located in the Bilge, just above the “Slosh Line”. A good rule
of thumb is to install no lower than the height of the starter solenoid. Avoid locating sensors near
manifold or exhaust systems, as high heat may damage the sensor.
Use the appropriate #8 mounting hardware to mount the Gasoline Fume Sensor in the desired
location. The rubber gasket should be installed between the sensor and the mounting surface.
Connect to the Extension Cable using the attached quick-disconnect connectors.

Part Number 18141, H, 01/28/2020
Electrical Connections (G1BR-B01-D/G1CR-B01-D or G2BS-B01-D)
The Display Unit operates on 9-30V DC. A Red and a Black 16 GA wire are provided for connecting
to the power source. Connect the Red wire to Power (+) with an inline 1.0 Amp fuse. Connect the
Black wire to Ground (-).
A 2A fused Yellow 16 GA wire is provided for connecting the Display Unit to the Bilge Blower
system. Connect the Yellow wire to terminal 85 of MB30RLY/MB30RLY-24. Connect the positive
(+) voltage to terminals 30, 86, and the Manual Blower Switch. Connect the Ground to the Blower
System.
NOTE
UNITS MANUFACTURED PRIOR TO JANUARY 01, 2018 DO NOT INCLUDE THE 2A FUSE. A
DEDICATED 2A FUSE OR BREAKER SHOULD BE USED TO POWER THE BILGE BLOWER SYSTEM.
NOTE
IMPROPER CONNECTIONS WILL DAMAGE THE DISPLAY UNIT AND WILL VOID WARRANTY.
Testing the System Operation
The Gasoline Fume Detectors can be tested by pressing the “Check/Reset”button on the face of
the Display Unit. The Display Unit will cycle through the LEDs and the alarm horn will activate
while the LEDs cycle.
Unplug the Gasoline Fume Sensor from each channel of the Detection System one at a time. The
Yellow “Fault” LED should illuminate. If the Yellow LED does not illuminate, remove Display Unit
and return direct to manufacturer following the instructions at the back of this manual.
Press the Blower button on the Display Unit. The Blower system should turn on until the button is
released.
Testing the Gasoline Fume Sensors
WARNING
DO NOT USE A GASOLINE SOAKED RAG OR A PARTIALLY FULL CONTAINER OF GASOLINE TO TEST A
SENSOR. THE RAW GASOLINE COULD IGNITE, RESULTING IN SERIOUS INJURY.
Test the Sensors by holding an unlit Butane lighter to the sensor. Within a few seconds, the Red
“Danger” LED should illuminate, Blower will activate, and the alarm horn will sound. Remove the
lighter from the Sensor and mute the alarm horn. After approximately one minute, the Red LED
will shut off.

Part Number 18141, H, 01/28/2020
Maintenance
The system should be tested periodically in the fashion described in the previous sections. Due to
the harsh environmental conditions in marine applications, it is recommended to replace the
Gasoline Fume Sensors every 3-4 years.
In the Event of an Alarm
Immediately have all passengers and crew exit the passenger compartment and vessel if possible.
Ventilate the space being monitored.
Carefully check all fuel lines and other potential sources of gasoline fume leaks. If leaks are
identified, shut off fuel supply and make any necessary repairs.
