3.5 ENGINE ROOM FIRE-FIGHTING SYSTEM

The engine room is protected by its own fire-fighting system, with automatic or manual activation, which uses type NOVEC gas as extinguishing agent. The cylinder is installed on the bow bulkhead of the engine room.
The discharge is automatically activated by means of a glass flask filled with liquid; when the temperature rises, the liquid expands until the flask breaks, and the extinguisher discharge activates.

The vial is mounted on the cylinder itself The extinguisher can also be activated manually; the discharge is controlled by the tie rod located in the fire station in the left cabinet of the stern cockpit next to the descent into the engine room.
The system is equipped with a control unit which in case of discharge, automatically stops the engines, the generators and the extractors in the engine room.
In the main helm station there is a panel for the control of the fire fighting system, described hereunder:

1. Green light
• Indicates that the extinguisher is full.
2. Red light
• Indicates that the extinguisher is empty.
3. SILENCE button
• It turns off the acoustic signal which indicates that the system is operating and that the extinguisher is releasing gas.
4. DIMMER:
• It varies the brightness of the control lights of the CHARGE/ OVERRIDE panel.
5. OVERRIDE button
• When this button is pressed, the control unit which, in case of extinguisher discharge, stops the engines, generators and electric extractors, is cut OFF.
• In OVERRIDE position the control unit is disabled.

WARNING

The OVERRIDE button must be pressed only when navigating in confined waters or with a collision hazard and to restart the engines after the system’s discharge.

CAUTION

The OVERRIDE button must only be used in case of real emergency.

CAUTION

The engine room is equipped with fixed fighting system. To avoid asphyxia, leave the area before the system’s discharge. After discharge, ventilate the area before entering.
