CAUTION

THE INSTALLED FM-200 SYSTEMS ARE MANUALLY ACTUATED.

IT IS IMPERATIVE YOU BECOME TOTALLY VERSED IN THE OPERATION

AND MAINTENANCE OF THESE SYSTEMS.

1.5 ENGINE ROOM. This manually actuated system is designed and installed to protect the Engine Room and

bilge (3-25-0-E), Frames 25 to 44. The physical location of this system, less FM-200 distribution piping and

nozzles, Electric Horn/Strobe, and Warning Lights (Amber Strobe), is installed outside of the protected space. Two

(2) each 600 pound cylinders and supporting components, installed on the forward bulkhead, Frame 42 1/2, A/C

and Emergency Generator Room (1-43-0-E), provide protection for the Engine Room and bilge. One (1) each 350

pound cylinder and supporting components, installed on the 7'-0" off centerline longitudinal bulkhead, Starboard

side, Frames 23 to 24, Tunnel (3-17-0-Q), provide protection for the Forward Engine Room

(MCC/Storeroom/Machine shop areas) and bilges.

1.6 TUNNEL. This manually actuated system is designed and installed to protect the Tunnel and bilge (3-17-0-Q),

Frames 17 to 25. The physical location of this system, less FM-200 distribution piping and nozzles, Electric

Horn/Strobe, and Warning Light (Amber Strobe), is installed outside of the protected space. One (1) each 350

pound FM-200 cylinder and supporting components, installed on the 7'-0" off centerline longitudinal bulkhead, Port

side, Frames 26 to 27, Engine Room (3-25-0-E), provide protection for the Tunnel and bilge.

1.7 BOW THRUSTER ROOM. This manually actuated system is designed and installed to protect the Bow

Thruster Room and bilge (3-5-0-E), Frames 5 to 17. The physical location of this system, less FM-200 distribution

piping and nozzles, Electric Horn/Strobe, and Warning Light (Amber Strobe), is installed outside of the protected

space. One (1) each 350 pound FM-200 cylinder and supporting components, installed on the 7'-0" off centerline

longitudinal bulkhead, Port side, Frames 19 to 20, Tunnel (3-17-0-Q), provides protection for Bow Thruster Room

and bilge.

1.8 PAINT LOCKER. This manually actuated system is designed and installed to protect the Paint Locker (1-0-2-

Q), Frames 0 to 13. The physical location of this system, less FM-200 distribution piping and nozzle and FM-200

Siren, is installed outside the protected space. One (1) each 125 pound FM-200 cylinder and supporting

components, installed on the 7'-0" off centerline longitudinal bulkhead, Port side, Frame 10, Bow Thruster Room (3-

5-0-E), provide protection for the Paint Locker.

1.9 A/C AND EMERGENCY GENERATOR ROOM. This manually activated system is designed

and installed to protect the A/C and Emergency Generator Room (1-43-0-E), Frames 42 1/2 to 52. The physical

location of this system, less FM-200 distribution piping and nozzles, Electric Horn/Strobe, and Warning Light

(Amber Strobe), is installed outside of the protected space. One (1) each 125 pound FM-200 cylinder and

supporting components, installed in the Stowage Locker (1-43-1-Q), Frames 43 to 44, provides protection for A/C

and Emergency Generator Room.

1.10 RELATED INSTALLATIONS. The Engine Room, Tunnel, and Bow Thruster Room FM-200

installations are supplemented by the installation of a Water Washdown System (WWS). This manually activated

system serves to quickly reduce compartment temperature prior to discharge of FM-200 agent, minimizes

production of Hydrogen Fluoride (HF) Gas generated as a result of FM-200 agent decomposition from contact with

hot surfaces and flame at temperatures above 1300F, aids in scrubbing of any HF Gas generated, and expedites

ventilation of the compartment. Operation instructions for the WWS are contained in TM 55-1925-223-10

paragraph 2-64.
