12.8.4 Fixed fire-fighting system in the engine room
The engineroom is equipped with an independent firefighting system that
can be activated either automatically or manually and uses FE-241 as
extinguishing agent. The cylinder is fitted on the forward bulkhead of the
engineroom starboard.
The discharge is controlled automatically through a glass flask filled with
liquid; when the temperature in the engine room rises, the liquid expands
until the flask breaks and the extinguisher discharge activates. The flask
is fitted on the same cylinder.
The extinguisher can also be activated manually, the discharge is
controlled by the tie rod placed in the aft starboard cockpit inside of a
suitable peak closed with a hatch.
In the helm station is placed the control panel for the firefighting system.
The red indicator light will illuminate on the helm station panel or on main
electric panel and the buzzer sounds, indicating an overheat condition in
the engineroom.
Acknowledge the condition by briefly pressing the test button, located in
the helm station or on the main electric panel. The alarm horn will stop
sounding. The light will remain illuminated until the heat detectors reset
themselves.
The system can be tested at any time by pressing the relevant test button.
When the button is pressed, the light will illuminate, and the alarm horn
will sound.
Releasing the button will cause the light to go out, and the horn will stop
sounding. An open circuit in the heat detection system wiring will also
cause the monitor to respond as if there is an overheat condition.

CAUTION
The fire monitor system monitors your vessel for fire (overheat) in the
engineroom only. The fire system monitor is separate from the onboard
fixed fire extinguishing system.
The fire system monitor will not detect fire outside of the engineroom.
The combination fire and bilge flood monitor is tested and silenced using
the same switches and controlled by the same power fuses. It can be
disabled completely by removing the fuse in the D.C. main supply panel
located in the engineroom.
S
CAUTION
Toxic by-products are produced when the fire-fighting agent (FE-241)
extinguishes the fire. Avoid breathing the fumes.
Inhalation of FE-241 (clorotetrafluoroethane) in high concentrations
may cause death without warning. Read the manual provided with the
fire extinguishing system for complete information.
Most fire-fighting agents will stop engines by oxygen depletion. Agent
FE-241 may not stop your engines or generator. If the engines are not
stopped quickly, the extinguishing agent concentration may be rapidly
reduced.
In order to give FE-241 a chance to extinguish a fire, the concentration
must remain as high as possible. Do not open the engineroom access
hatch.
The fixed fire extinguisher will fight fires only in the engineroom. Fires
outside the engineroom should be fought with the portable hand-held
extinguishers.
