4.6.5 Contact pressure gauge "extinguishing agent container"
FIGURE 4-11: Contact pressure gauge
1. Green area notating 10% pressure loss
Each valve has a connection for a contact pressure gauge. This connection is closed with a plug.
Pressure gauges must be ordered separately from the cylinders.
Since the connection is fitted with a check valve, the contact pressure gauge can be assembled
even if the extinguishing agent container is pressurized.
The automatic loss monitoring is set to a 10% pressure loss (scale area marked in green) based on
the nominal filling pressure.
