Supplies, which are not included with your Sea-Fire system and should be at hand before
indicator light installation, are as follows:
1. Five (5) Ampere in-line fuse and holder
2. Sufficient length of insulated 16 AWG stranded wire.
3. Crimp on wire connectors.
4. Crimp pliers, hand tools.
Attach one wire lead from the in-line fuse to the ignition position on the starter switch. Connect
other lead from the in-line fuse to the indicator light. Connect remaining indicator lead to one of
the Sea-Fire cylinder pressure switch connector wires. Connect the remaining cylinder pressure
switch lead to common ground, which may be the negative battery buss at the control panel, or
directly to the engine block (see Figure 3).
CAUTION: Electrical systems vary from vessel to vessel and these directions may not be
applicable for your installation. Should you have any doubts of safely accomplishing this
installation, contact a qualified marine electrician or SEA-FIRE MARINE USA @ 410 687
5500 for technical assistance.

SYSTEM MAINTENANCE
Cylinder Inspection / Cylinder Testing
Model FG DOT 39 cylinders are non-reusable and do not require any testing.
Model FD DOT 4B, 4BW and 3AL cylinders are reusable and must be periodically tested. DOT
4B and 4BW cylinders may be inspected by an external visual inspection in accordance with
Section 3 of CGA C-6, Standard for Visual Inspection of Steel Compressed Cylinders, and shall
be performed every 5 years except the cylinders do not have to be emptied or stamped under
pressure. Inspection shall be made by competent personnel and results noted on a permanent
record tag. Alternatively the cylinders may be emptied and subjected to a hydrostatic test every
12 years in accordance with 49 CFR.
DOT 3AL cylinders must be emptied and subjected to a hydrostatic test every 12 years in
accordance with 49 CFR.
WARNING: DO NOT ATTEMPT TO DISASSEMBLE ANY PART OR COMPONENT OF THE
EXTINGUISHER. THIS UNIT IS PRESSURIZED AND SERIOUS INJURY COULD RESULT.
CONTACT THE FACTORY OR AN AUTHORIZED DEALER FOR SERVICE INFORMATION.
Before operating, visually check to insure indicator light is operational, and cylinder pressure
indicator is in the normal range. All fire suppression systems containing liquefied gas require
periodic weighing to ensure a fully charged unit. Pressure gauges indicate the ability to discharge
the agent but not the quantity of extinguishing agent. The cylinder (less bracket) must be weighed
on at least a semiannual basis and be replaced immediately if gross weight has decreased by
quantity noted on the specification label.
Never paint or obstruct the cylinder manifold or sensor valve/detector, as this will adversely affect
its operating characteristic. FD models are refillable, see nameplate on cylinder for instructions
and OUT OF WARRANTY REPLACEMENTS/RECHARGES section of this manual.
REMINDER:
• FREQUENTLY CHECK GAUGE FOR PROPER PRESSURE
• WEIGH CYLINDER TO INSURE AMPLE EXTINGUISHER AGENT

LIMITATIONS
Sea-Fire “FG” and “FD” model series FM-200
®
automatic fire extinguishers are designed and
tested to extinguish Class B (flammable liquid) fires in enclosed compartments only. Any open
doors or hatches will allow discharging agent to escape and will seriously affect the ability of the
agent to extinguish the fire.
Only one extinguisher may be used to protect a compartment. If more then one extinguisher is
used to achieve the required amount of agent concentration, there is no guarantee that several
extinguishers will actuate simultaneously as each extinguisher operates independently. Several
extinguishers may be used only if each independent extinguisher is capable of protecting the
entire volume of the compartment.
OPTIONAL EQUIPMENT
SDDA I — Panel mounted visual/audible discharge alarm unit
ESRS-2 — Panel mounted system status indicator with override switch for engine(s) restart. For
use with the ESRS engine shutdown system as a replacement or add-on second helm
station.
ESRS III,V,VII — Engine and powered ventilation (blower) shutdown system. Includes one circuit
control unit and one panel mounted ESRS-2 visual/audible system status indicator with
override switch for engine restart. Available with 3, 5, or 8 control circuits in 12 or 24 VDC
models.
ESRS-W/T III,V,VIII — Same as ESRS-MARK shutdown system, but also includes a factory-
installed nominal 20-second release timer on the engines control circuits. For use on
diesel engines that shutdown through activation of a momentary device (i.e. push button,
lever etc.).
SFAB 12 (24) — Discharge alarm bell 6" round 12 or 24 VDC models.
ESEH-10 — 10 foot (3.05 meter) extender harness for use with ESRS systems.
ESEH-30 — 30 foot (9.15 meter) extender harness for use with ESRS systems.
Clean agent (FM-200*) Portable Fire Extinguishers are also available.
Contact Sea-Fire or an authorized Sea-Fire dealer for details.
