 TM 55-1905-223-10
a. Authority To Actuate FM-200 Systems. The authority to actuate the FM-200 fixed fire
extinguishing system protecting engine room, tunnel, bow thruster room, paint locker and
air conditioner and emergency generator room will be issued by the person in charge at the
scene.
b. Actuation Procedures, Engine Room FM-200 System. All fire scenarios and situations leading
to the decision when to actuate the FM-200 total flooding fire extinguishing system are not
intended to be discussed here. Refer to the US Army Fire Fighting Doctrine for guidance.
However, the following steps must be completed to effectively deploy the FM-200 as designed.
In the event the FM-200 Fixed Fire Fighting System is to be actuated, the following steps must
be accomplished prior to activation of the system.
(1) Evacuate All Personnel From Space.
WARNING
In the event the FM-200 System electric horn/strobe or warning
lights (amber strobe) are activated, leave the protected space
immediately.
FM-200 is being released within 60 seconds, death or serious
injury could occur.
The Watch Officer or on-scene commander must ensure all personnel have evacuated
the space and are all accounted for.
(2) Activate The Water Washdown System (WWS). In order to operate the WWS, the fire
main system must be charged. Ensure that the Bow Thruster Emergency Fire Pump is
placed on line to the maximum operating pressure.
WARNING
The Water Washdown System (WWS), installed to augment the
the engine room FM-200 System, shall be activated prior to
actuation of the FM-200 Fixed Fire Extinguishing System.
To provide adequate flow of seawater to the engine room WWS,
the bow thruster emergency fire pump must be operated at a
minimum pressure of 121 psi.
During operation of the WWS, sufficient fire main capacity exists
for four (4) 1 ˝ fire hoses at full stream or nine (9) 1 ˝ hoses
at spray.
Failure to operate bow thruster emergency pump at 121 psi could
result in equipment damage or serious injury to personnel.
