Operation Of Fireboy Engine Shutdown/Override System - Fireboy- Xintex ESC Series Owner's Manual & Installation Instructions

Operation of Fireboy Engine Shutdown/Override System

The Fireboy Engine Shutdown Control (ESC) System operates by means of relays. The Shutdown
Control Module is connected to the Fireboy Extinguisher by means of the Pressure Switch. When
the Pressure Switch opens on the Fireboy Extinguisher, the relays on the Shutdown Control
Module activate, disconnecting or connecting power to the connected systems.
The Status of the Engine Shutdown Control (ESC) System is displayed on the Helm Display Unit.
The Helm Display Unit has a Green and a Red LED located on the face, and a button to control
Override Mode. The Green LED will be illuminated in normal operation, indicating that the Fire
Extinguisher is charged. If the Extinguisher's pressure drops, then the Green LED will turn OFF and
the Red LED and horn will turn ON.
Press the Override button to activate the Override Mode. The Red LED will begin flashing,
indicating that you are now in Override Mode. You will now be able to restart your engines and
maneuver the vessel to safety. The Shutdown Control/Override System will remain in Override
Mode until it is manually deactivated by pressing the Override button while the system is
powered. To notify you that you are still in Override Mode, each time the engines are restarted,
both LEDs will illuminate, and the system will produce multiple beeps, then the Red LED will begin
flashing. Press the Override button again to exit Override Mode.
The DU-SBH-20 also has a button to control the brightness of the Green LED. Whenever the unit
is first powered on, the Green LED will be at its brightest setting. Press the button to cycle
through the three LED brightness settings.
