26. FM-200 alarm (figure 2, item 26). The FM-200 alarm indicates the FM-200 agent is being released into the engine

room and AMS 1.

27. Duplex strainer (figure 2, item 27). The duplex strainer removes sediment and other large solids from the raw water

used to cool the bow thruster engine (figure 2, item 15) and pump drive engine (figure 2, item 19).

28. Raw water strainer and Aqueous Film Forming Foam (AFFF) proportioner pressure gauges (figure 2, item 28). The raw

water strainer differential pressure gauge measures the differential pressure across the raw water strainer. Excessive

differential pressure indicates a clogged strainer. The AFFF proportioner pressure gauge indicates the pressure at the

AFFF proportioner.

29. MSD blower (figure 2, item 29). This blower aerates the sewage in the MSD to permit decomposition.

30. AFFF pump (figure 2, item 30). The AFFF pump supplies AFFF concentrate from the AFFF storage tank to the

proportioner.

31. MSD wet well (figure 2, item 31). The MSD wet well is where the chlorine from the table chlorinator disinfects the

effluent discharged from the media tank.

32. Sound powered telephone and storage box (figure 2, item 32). The sound powered telephone provides intraship

communication.

33. MSD media tank (figure 2, item 33). The MSD media tank is where sewage is biologically decomposed.

34. MSD discharge pump pressure gauge (figure 2, item 34). This gauge measures the discharge pump pressure.

35. MSD discharge pump (figure 2, item 35). The MSD discharge pump discharges effluent from the wet well overboard

after treatment.

36. Hot water recirculating pump pressure differential gauge (figure 2, item 36). This gauge indicates the pressure differen-

tial across the hot water recirculating pump.

37. Sewage holding tank (figure 2, item 37). The sewage holding tank (located below tank top level) holds the processed or

unprocessed sewage until it is pumped through the shore connection.

38. MSD motor controller (figure 2, item 38). The MSD motor controller provides overload protection and control for the

MSD discharge pump and blower.

39. Sewage holding tank level indicator (figure 2, item 39). This tank level indicator indicates the level of matter present in

the sewage holding tank.

40. Hot potable water recirculating pump motor controller (figure 2, item 40). This controller turns the hot potable water

recirculating pump ON and OFF.

41. AFFF pump motor controller (figure 2, item 41). This controller provides overload protection and control for the AFFF

pump.

42. Air compressor 2 motor controller (figure 2, item 42). This controller allows the operator to turn the air compressor 2

ON and OFF and to select AUTOMATIC operation.

43. Air compressor 1 motor controller (figure 2, item 43). This controller allows the operator to turn the air compressor 1

ON and OFF and to select AUTOMATIC operation situations.
