Equipment Operation

6-47

If equipped, a gas vapor detector is a state of the art fume montoring

and alarm system. It ia highly effective detector of engine compartment

gasoline fumes from unburned hydrocarbons wmitted from faulty

exhaust systems and hydrogen battery vapors.

The unit operates with a head unit at the helm, a sensor located in

the bilge installed just above the normal accumulation of oily bilge

water.

A .5 amp buss fuse (for overcurrent protection) is located behind the

helm head unit.

Operation

The display panel at the helm features 3 windows. The left window

is a green power on indicator. The right window is and opening for

the Var-a-Brite light intensity detector. The center window is the red

warning indicator.

To check for fumes, turn the ignition key to the “on” position. the

green power on LED will show on and the red warning LED may

light momentarily to indicate a warm-up period for the sensor. The

alarm horn will not sound during this period.

If a vapor build-up reaches 10-20% of lower explosion limit the

red warning LED will light indicating a detection of fumes. Should

this condition last for longer than 10 seconds, the alarm horn will

sound.

The alarm will continue as long as vapors are present. The alarm horn

may be silenced by pressing the “mute” switch, the the Red warning

light will remain on until the vapor problem has been resolved.

NOTE: THE PROBLEM SHOULD NEVER BE CONSIDERED

CORRECTED UNTIL THE RED WARNING LIGHT GOES

OUT.

If the red LED begins to glow softly and or intermittently, it is an

indication that the gasoline vapor build-up is beginning to occur and

you can anticipate a full alarm momentarily.
