The car is equipped with an FIA homologated fire extinguishing system.
AFFF extinguishing agent is used. The cylinder has two separate
chambers each with a capacity of two litres. The extinguishing agent is
discharged through three nozzles located in the engine bay and a further
three located within the cockpit.
The fire extinguisher is activated by a push button mounted on the
dashboard or by the emergency switch located on the left hand side of
the windscreen cowl.
The system's operating range is between -15° C and +60°C. The
extinguisher cylinder must be protected from frost and should never be
stored where the ambient temperature can drop below -15°C.
The operating pressure of system is 14 bars, and should be checked
regularly using the manometer mounted to the extinguisher bottle.
Attention: The extinguishing agent, extinguisher cylinder and
flexible pipes should be replaced after a maximum of 2 years
from the date of manufacture by original new spare parts.
The extinguisher system is live when the toggle switch on the trigger
box is set in the "System Active" position. The extinguisher is
discharged by pressing the dash mounted push button and/or by
pushing the button located on the windscreen cowl.
Hold the toggle switch on the trigger box in the "Battery Check" position.
If the battery charge state is good the trigger box warning lamp will

glow:
Check battery charge state (refer to 'Battery Installation').
Check the cable connection to the buttons (refer to 'Trigger box wiring
harness')
