FM-200 LOCAL ACTUATION COMPONENTS
Figure 8. FM-200 Local Actuation Components
Table 8. FM-200 Local Actuation Components (refer to figure 8)
This control head permits both manual and pressure actuation
of the FM-200 discharge delay valve. When activated manually,
FM-200 discharge is activated without warning horns, strobe
lights or the FM-200 bell sounding.
Discharge Delay Valve
This valve determines the status of the 60-second delay. When
OPEN, the 60-second delay is overridden. When CLOSED, the
60-second delay is active.
Pressure Switch PS-1
When the FM-200 system is actuated, PS-1 automatically secures
engine room and AMS 1 ventilation, Ship's Service Diesel Generator
(SSDG) 1, SSDG 2, the bow thruster engine, the pump drive engine,
and the fuel oil transfer pumps. PS-1 also sounds an alarm bell and
energizes the amber strobe lights.
Pressure Switch PS-1A
When the FM-200 system is actuated, PS-1A energizes the warning
horns in the engine room and AMS 1, and the amber strobe lights
in the engine room, AMS 1, and AMS 2.
CO2 Discharge Valve
This valve controls the discharge rate of the CO2 gas from the
cylinder that actuates the FM-200 system.
