Layout and function description:
fire extinguishing system (option)
The fire extinguishing system comprises
the following five main components: Ex-
tinguisher tank, detection agent tank,
detection line, extinguisher lines and ex-
tinguisher nozzles.
A trigger valve is fitted to the extinguish-
er tank. The trigger valve is connected
to the detection agent tank by the de-
tection line. The pressure (approxim-
ately 24 bar) of the detection agent tank
therefore acts on the trigger valve. Ex-
tinguisher lines are connected to the
extinguisher tank. The extinguisher lines
in the engine compartment are equipped
with extinguisher nozzles. The detection
agent tank is filled with nitrogen gas and
Glysantin.
In the event of a fire in the engine com-
partment or in the installation area of
the auxiliary heating unit, the detec-
tion line melts and the nitrogen gas
and Glysantin escape. The drop in pres-
sure in the detection line depressurises
the trigger valve on the extinguisher
