FIRE EXTINGUISHER- AUTOMATIC
OVERVIEW
The Fireboy automatic fi re extinguishing system is located
in the bilge at the forward engine bulkhead. See the illus-
tration. 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 fi re to
re-fl ash.
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 fumes and
using blowers.
Read the information in chapter 4 regarding the dash in-
stalled portion of the fi re extinguisher system. When the
system actuation starts you may hear a loud sound simiar to
that of small arms fi re, 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 actuation
time when a fi re occurs is dependent on the severity of
the fi re.
When the automatic fi re extinguisher activates IMMEDI-
ATELY SHUT DOWN ALL ENGINES, POWERED
VENTILATION (BLOWER), ELECTRICAL SYSTEMS
AND EXTINGUISH ALL SMOKING MATERIALS.
DO NOT OPEN THE ENGINE COMPARTMENT
IMMEDIATELY!
Allow the agent to “soak” the compartment for a period of
time and wait for hot metals and any fuels to cool before
inspecting for the fi re cause. Premature opening of the
engine compartment allows an in-rushing of oxygen and
could result in a fl ash-back. When the engine compart-
ment is opened have approved portable fi re extinguishers
ready to use.
OPERATION-AUTOMATIC
OPERATION-MANUAL
If a fi re 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 T-handle fi rmly and
release. A loud “rushing” or air” sound will be heard.
Complete discharge will take several seconds. DO NOT
OPEN THE COMPARTMENT IMMEDIATELY! Keep
the compartment closed for a period of time suffi cient to
allow the agent to soak all areas of the protected space.
This allows hot metals to cool.
