FM-200 FIRE SUPPRESSION SYSTEM
The engine room and Auxiliary Machine Space (AMS) 1 are fitted with a FM-200 fire suppression system. The
system is a manually actuated, stand-alone, total flooding fire suppression system. The system is capable of
extinguishing Class A, Class B, and Class C fires when properly deployed. The system consists of two 600 lb
(272 kg) FM-200 cylinder assemblies (figure 5, item 1), a 200 lb (91 kg) FM-200 cylinder assembly (figure 6,
item 1), control heads (figures 5 and 6, item 2), discharge nozzles (figures 5 and 6, item 3), and FM-200 pull
boxes (figures 7 and 8).
When the FM-200 system is actuated, ventilation to and from the engineering spaces, the ship's service diesel
generators, and the bow thruster and pump drive engines are automatically shut down to prevent FM-200 gas
from being extracted from the spaces. When a FM-200 pull box is actuated, horns sound, strobes flash, and the
FM-200 alarm bell sounds to alert personnel to evacuate the space. A 60-second delay is provided before the
FM-200 agent is released to allow for evacuation of the engineering spaces.
