CHAPTER 6
6-70
If equipped, a gas vapor detector is a state of the art fume monitoring
and alarm system. It ia highly effective detector of engine compartment
gasoline fumes from unburned hydrocarbons emitted 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 over current 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 an 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 illuminate 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 Red warning light
will remain on until the vapor problem has been resolved.
NOTE: THE PROBLEM SHOULD NEVER BE CONSIDERED
CORRECTED UNTIL RED WARNING LIGHT IS OUT.
