3.4 ENGINE ROOM FIRE-FIGHTING SYSTEM

The engine room is protected by its own fire-fighting system, with automatic or manual activation, which uses type FM200 gas as extinguishing agent. The cylinder is installed on the centre of the engine room.
The discharge is automatically activated by means of a glass flask filled with liquid; when the temperature in the engine room rises, the liquid expands until the flask breaks, and the extinguisher discharge activates.
The flask is fitted on the same cylinder. The extinguisher can also be activated manually; release is controlled by the tie rod located on the crew area access ladder.
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 fly bridge 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 lamps 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.
