APPLICATION

FM-200® (CF3CHFCF3), the extinguishing agent, used in all Sea-Fire “FT’’ series fire extin­guishers, is a suitable EPA accepted alternate replacement for Halon. FM-200® is electrically
nonconductive and residue free extinguishing agent that requires no cleanup.

These features and the versatility of design make the “FT’’ series fire extinguisher ideal for a
broad range of applications. The systems are ideal for small volumes, 150 cubic feet or less,
that are difficult to access. These applications would include marine, recreational vehicles,
commercial and industrial use where flammable liquids are likely source of fire.

Application Examples:

• Engine Compartments (maximum 150 cubic feet)

• Bow Thrusters

• Small Generator Set Enclosures

• Consoles

• Electrical Enclosures

• Flammable Liquid Storage Areas

• Pump Enclosures

• Alternative Fuel Storage Areas
Sea-Fire “FT” extinguishers are designed to induce a minimum atmospheric concentration of

10.0% within the protected compartment.* The specification table in this manual lists the
minimum and maximum approved compartment volume (size) allowable for each model.
Volume can be determined by multiplying the compartment’s length x width x height which

equals the volume in cubic feet or meters (LxWxH=V).

Exception: If the boat manufacturer has placed a permanently affixed label in the compart­ment specifying the gross volume less the volume of permanently installed tankage, then
this volume may be used to determine the proper size extinguisher. Check specification table
for proper application before making installation.

REMINDER: Sea-Fire systems shall be considered as supplementary to the number of portable
fire extinguishers required on-board and are designed and intended for enclosed unoccupied
compartment installations that are not subject to direct weather or water.

SYSTEM OPERATIONS

Sea-Fire units described in this manual are automatically actuated by a heat actuated tube.
Discharge will occur as a result of direct flame impingement. The Sea-Fire FT system uses
the supplied length of temperature sensitive tubing as both detection and delivery system.
The tubing should be routed close to the hazard, where fire is likely to occur, but away from
heat sources that could accidentally cause it to operate. Upon flame impingement, the tubing
will rupture, and the extinguishing agent will discharge through the rupture point. No separate
discharge nozzle is needed.

CAUTION: IN CASE OF EXTINGUISHER DISCHARGE, DO NOT RUSH TO OPEN THE
PROTECTED COMPARTMENT. LET THE EXTINGUISHING AGENT WORK FOR SEVERAL
MINUTES. HAVE A PORTABLE EXTINGUISHER AVAILABLE AND USE CARE WHEN
OPENING THE COMPARTMENT.

AVOID BREATHING FIRE RELATED FUMES OR VAPOR.

NOTE: It is important to retain the designed vapor concentration within the compartment to
insure complete fire outage. Upon discharge, all powered ventilation (blowers) must be shut
down.

PRESSURE SWITCH

Sea-Fire “FT” series extinguishers are equipped with a factory installed pressure switch which
is intended for cylinder pressure supervision and may also be used to control other electrical
functions (engine shutdown, air exchange equipment, electric supply, etc.)

When using the pressure switch as an electrical disconnect for any equipment shutdown
function, a means of overriding (bypassing, shunting) the pressure switch must be provided
in order to return the affected equipment to an operational mode after extinguisher discharge
has occurred. The pressure switch is a single pole single throw (SPST) type that is normally
closed (NC) with the system in the charged condition. Discharge or loss of system pressure
will release the contacts to an open state thereby cutting off any electrical current flow.

NEVER USE PRESSURE SWITCH FOR ELECTRICAL LOADS OVER RATED CAPACITY.

SWITCH SPECIFICATIONS

4.0 AMPS AT 12 VDC 2.0 AMPS AT 28 VDC

For applications requiring larger load capacities, see OPTIONAL EQUIPMENT section IN
THIS manual or contact factory.

DIESEL ENGINES

Continued operation of diesel engine(s) and or powered ventilation units will deplete the
extinguishing agent and may cause a fire re-flash. Diesel engine(s) must be automatically

shutdown upon extinguisher discharge.

Note: Power ventilation (blowers) that exceeds one air change per minute within the protected
compartment must be automatically shutdown upon extinguisher discharge.*

*ABYC requirement - Standard A-4

GASOLINE ENGINES

WARNING: GASOLINE ENGINES AND FANS SHOULD BE AUTOMATICALLY OR
MANUALL Y SHUT DOWN AT TIME OF DISCHARGE.

Shutdown may be accomplished by interruption of the electrical circuit between the ignition
switch and the engine coils.

NOTE: Sea-Fire optional engine interrupt systems will automatically shut down engines and
powered ventilation upon discharge of the fire SUPPRESSION system. They are available in
12 and 24-volt models with 3, 5 or 8 control circuits, refer to OPTIONAL EQUIPMENT section
in this manual.

OTHER APPLICATIONS

• Engine Compartments (maximum 150 cubic feet)

• Bow Thrusters

• Small Generator Set Enclosures

• Consoles

• Electrical Enclosures

• Flammable Liquid Storage Areas

• Pump Enclosures

• Alternative Fuel Storage Areas
In case of a fire and system discharged, the electrical supply to the motor must be discon-

nected. Failure to do so may result in re-ignition after the FM-200® concentration depletes.
Disconnect may be accomplished by using a shutdown system. See OPTIONAL EQUIPMENT .

EXTINGUISHER INSTALLATION:

Step 1 Carefully remove extinguisher from carton and visually check for damage in shipment.
Step 2 To ensure that the extinguisher is operational, both the weight and pressure indicator

must conform with the extinguisher specification as shown on the nameplate. Weigh
extinguisher (less bracket) on an accurate calibrated scale before installing. Record
date and weight on tag provided for this purpose.

Step 3 Choose a suitable location inside or outside the protected area where accidental

damage is unlikely to occur.

Step 4 Ensure mounting surface is durable (Prefer no less than __ inch. Mounting on fiber-

glass surfaces: A backing washer (flat) or plate should be utilized if the thickness is
less than inch.

Step 5 Using the bracket as a template, drill (4) ____” diameter holes. Mount the bracket

using no less than Grade 5 corrosive resistant ____” fasteners. (See Figure 5)

Step 6 Install the extinguisher into the bracket and latch clamp.
Step 7 If required to route detection tube through a compartment wall, drill hole 25/64" diam-

eter, and utilize supplied grommet to protect tube from wear. (See Figure 6)

Figure 5

Step 8 Secure the detection tubing to the bulkhead by using the clips and screws supplied.

Nylon wire ties may be used in lieu of the clips and screws. Note: Do not exceed a
bend radius of 6 inches during the routing of the tube.

WARNING

WHEN INSTALLING THE DETECTION TUBING, DO NOT KINK THE TUBING AND DO
NOT EXCEED THE MINIMUM BEND RADIUS. FAILURE TO FOLLOW THESE DIRECTIONS
CAN RESULT IN A SYSTEM FAILURE. (See Figure 6)

Step 9 Ensure the spring nut fitting is on tube, and attach by carefully working the tube

completely down on the nipple fitting on cylinder assembly/ (Note: Do not kink tub­ing, if kink occurs, remove effected area with razor.

Step 10 Tighten fitting and tube to cylinder using 1/2" (12mm) wrench. Preferred torque

value is 3 - 4-1/2 inch pounds of force. Overtightening may cause tube to rupture.

Step 11 Activate system - Using a straight screwdriver, “open valve VERY SLOWL Y” counter

clockwise, 1/4 of a turn, to allow detection tube to fill with nitrogen.
Note: Label on valve indicates valve and system status. (ACTIVATE)
Step 12 After tubing is routed, and charged, verify there are no apparent damage, and that

the fitting ends of tubing are leak free.
Note: If a leak is detected, close valve, and re-tighten fittings. If leak persists, remove affected

zone and re-install. Ensure valve is open (Activate) at completion of installation.
