42C System Operations - 29
AUTOMATIC FIRE
EXTINGUISHER SYSTEM
Your 42C is equipped with a Automatic
Fire Extinguisher System, which is per-
manently mounted on the forward bulk-
head of the engine compartment.
The Automatic Fire Extinguisher System
(AFE) is designed for use in enclosed
compartments that are not normally occu-
pied by passengers and are not normally
subject to weather or water exposure. The
automatic fi re extinguisher is designed to
extinguish Class B fi res (fl ammable liq-
uids) and Class C fi res (electrical), which
would be the type that would normally oc-
cur within the confi ned area of the engine/
generator compartment.
NOTE: The automatic fi re extinguisher
system DOES NOT replace the need for
additional portable-type fi re extinguish-
ers required by the United States Coast
Guard.
The automatic fi re extinguisher is acti-
vated when the engine/generator compart-
ment reaches 165° Fahrenheit/74° Cel-
sius. The system releases HALON 1301
into the compartment, which immediately
converts to a safe, odorless, and electri-
cally non-conductive vapor that will not
harm the components in the engine/gen-
erator compartment. In contrast to other
fi re extinguishing materials, HALON 1301
leaves no residue, assisting in the even-
tual cleaning of the compartment.
The automatic fi re extinguishing system
on your 42C is equipped with a GREEN
indicator light, located on the helm switch
panel.
The purpose of this indicator light is to
alert the operator of the charge/discharge
status of the Automatic Fire Extinguish-
ing System. The indicator light will illumi-
nate when the ignition switch is turned to
the ON position when the system is fully
charged. If the indicator light fails to illu-
minate after turning on the ignition switch,
carefully examine the exterior of the en-
gine/generator compartment for evidence
of a fi re that may have discharged the
system by looking for signs of “scorching”
and by your sense of smell.
