several weeks or more.

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

surance company to find out if they have any requirements concerning this system.
