CONTROL HEAD
A cable operated control head is installed on the storage cylinder. The control head controls the discharge of FM-200 from
the storage cylinder. The control head has two methods of actuation. The primary actuation method is remote actuation via
a pull box located in the pilothouse. When the cable is pulled, the control head discharges FM-200 into the piping that leads
to the engine room. The secondary actuation method is local actuation via the manual lever mounted on the control head.
DISCHARGE NOZZLE
A 180 degree discharge nozzle, mounted in the engine room, centerline, overhead, discharges FM-200 into the engine room
after it is released by the control head. The discharge head ensures that the FM-200 is dispersed evenly throughout the
engine room to most effectively extinguish a fire.
PULL BOX
A remote pull box, located in the pilothouse behind the coxswain's seat, serves as the primary method of actuation for the fire
suppression system. The pull box is connected to the control head by a cable that is routed through a system of watertight
piping and corner pulleys.
