14.4 Fire suppression system
14.4.1 Daily checks and maintenance
If there is a pressure gauge fitted, then check that the needle on the pressure meter for the
containers is within the green zone.
On semi-automatic fire fighting systems, check that the LEDs are working as specified
in the Operator's Manual. Perform a test - press the green test button (7) for at least 1
second. The diodes come on successively and conclude with an alarm test of signal and
lamp.
14.4.2 Annual maintenance
In many countries, insurance companies require proof that a qualified engineer has inspec-
ted and approved the fire fighting system annually. We recommend checking with your in-
surance company to find out if they have any requirements concerning this system.
14.4.3 Electric Welding, Steam Cleaning and High Pressure Cleaning
CAUTION
Risk of injury
The operator's panel on semi-automatic fire fighting systems must be disabled for the
following tasks:
u Electric welding, battery charging and start help. Harmful currents can damage the
electronics.
u Steam cleaning. The heat detectors are triggered at 120°C and could be activated by
the steam.
u High-pressure washing. Components or cables could be damaged by the jets and trig-
ger the system.
Once the semi-automatic fire fighting system is enabled again, make sure the LEDs and
the system work as specified in the Operator's Manual. Perform a test - press the green
test button on the operator's panel for at least 1 second. The diodes come on successively
and conclude with an alarm test of signal and lamp. A description of the operator's panel
can be found in the Operator's Manual
