FIRE EXTINGUISHER- AUTOMATIC

OVERVIEW
The Fireboy automatic fire extinguishing system is lo-
cated in the bilge at the forward engine bulkhead. See
the illustration. The system uses a environmentally friendly
agent FE-241 which has been approved by the EPA to
replace the old Halon agent. This system is formulated
only for use in the engine space or bilge of your vessel.
FE-241 is to be used with gasoline fuel systems only since
the agent will not "stall" diesel engines. This could cause
a fire to reflash.

OPERATION-AUTOMATIC

Fireboy systems are not nor are they intended to be ex-
plosion suppression devices. Boat owner's still need to
take normal precautions for checking gasoline fumes
and using blowers.
Read the information in chapter 4 regarding the dash in-
stalled portion of the fire extinguisher system. When the
system actuation starts you may hear a loud sound simiar
to that of small arms fire, followed by a rushing air sound.
The system will show actuation whenever the ignition
key is ON and the indicator light is OFF. The actual ac-
tuation time when a fire occurs is dependent on the se-
verity of the fire.
When the automatic fire extinguisher activates IMME-
DIATELY SHUT DOWN ALL ENGINES, POW-
ERED VENTILATION (BLOWER), ELECTRICAL
SYSTEMS AND EXTINGUISH ALL SMOKING MA-
TERIALS. DO NOT OPEN THE ENGINE COM-
PARTMENT IMMEDIATELY.
Allow the agent to "soak" the compartment for a period
of time and wait for hot metals and any fuels to cool be-
fore inspecting for the fire cause. Premature opening of
the engine compartment allows an in-rushing of oxygen
and could result in a flash-back. When the engine com-
partment is opened have approved portable fire extin-
guishers ready to use.

OPERATION-MANUAL

If a fire has started in the engine compartment where the
Fireboy is located, DO NOT WAIT FOR AUTOMATIC
ACTIVATION. Release the system manually. Close any
opened hatches leading to the engine compartment, shut
down all forced ventilation devices, engines, generators
and electrical components. Remove the safety pin from
the "Fire" T-handle, and pull firmly and release. A loud
"rushing" or air" sound will be heard. Complete discharge
will take several seconds. DO NOT OPEN THE COM-
PARTMENT IMMEDIATELY! Keep the compartment
closed for a period of time sufficient to allow the agent to
soak all areas of the protected space. This allows hot metals
to cool.
