 TM 55-1905-223-10
WARNING
The WWS should always be ready to immediately deploy by disengaging
the locking mechanism on the ball valve handle. Pad locking of this
handle should only occur during system maintenance or equipment
damage, death or serious injury could occur.
Actuate the FM-200 fixed fire extinguishing system in accordance with the instructions contained
in paragraph 2-63.d., and the FM-200 actuation placards located at the FM-200 actuation
stations.
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.
NOTE
Upon actuation of the FM-200 fire extinguishing system, a 60 second
delay in agent discharge will be experienced. During this delay, FM-200
system electric horn/strobe will sound, FM-200 warning bell will sound,
and the FM-200 warning light (amber strobe) will be illuminated.
Activation of the fixed FM-200 fire extinguishing system will result in automatic shut down of the
following equipment and ventilation system:
Bow Thruster Room Supply Fan
Bow Thruster Room Diesel Engine
WARNING
The Water Washdown System (WWS) is not designed nor intended to
be a stand alone fire extinguishing system. It is designed to be used
in conjunction with the installed FM-200 fixed fire extinguishing system.
In the event of an onboard fire emergency failure to activate the FM-200
fixed fire extinguishing could result in equipment damage, death or
serious injury.
Operate the WWS for a minimum of fifteen (15) minutes. During the WWS operating period,
approximately every three (3) minutes, open valve WWS-2, bow thruster room WWS strainer
blow off for approximately ten (10) seconds. This will allow any foreign matter to be flushed
from the in-line strainer basket.
WARNING
To reduce temperatures within the protected space and manage the risk
of HF exposure to humans, the WWS is designed and intended to be
operated for a minimum of 15 minutes. Failure to follow this procedure
to the full extent could result in serious injury or death to personnel.
