3.4.1 Fire-ghtingsystemoperation
The xed re-ghting system operates automatically when the temperature
exceeds 79°C. The discharge is driven by an automatic system consisting
of a glass ask lled with liquid and installed on the extinguisher cylinder.
When the temperature around the ask reaches the preset level, the liquid
expands until the ask breaks and the extinguisher activates. The system
can also be activated manually.
By pulling the tie rod, the system stops the engines, the generators and the
electric extractors automatically.
A panel located in the main helm station on the main deck it allow extin-
guisher discharge monitoring.
In case of re in the engine room, operate as follows:
• Shut down both engines and generators, if running, by means of push-
buttons in the helm stations;
• Turn off the battery breakers and all magneto-thermal switches of the
AC;
• Remove the security pin from the re-ghting tie rod, by slipping it off;
• Pull tie rod safety (2) for extinguisher discharge. The extinguisher can be
automatically discharged, but pull the tie rod anyway.
CAUTION
If the re breaks out underway, perform the distress call “MAY DAY”; if
the yacht is in the harbour, advise the Port Authority and evacuate all un-
necessary personnel.
CAUTION
Do not delay the re ghting because of a rescue call.
CAUTION
To shut OFF the engines, do not only push the stop buttons but also al-
ways turn the keys.
CAUTION
Keep the re ghting control tie rod efcient; service them and check for
their operation at regular intervals (as per rules in force).
CAUTION
Before setting up for navigation, it is necessary to open the lock and to
have the crew access free and the re-ghting control panel as well.
Also check that the safety pin of the cylinders has been removed.
