Input field for time period

Description
Time period between the automatic activation of the
extinguishing process and the start of the process of
flooding the flooding zone with extinguishing agent.
During this pre-warning time, people have a window
of time in which they are able to leave the flooding
zone.
Period of time for which a warning will be issued to
any people in the flooding zone when extinguishing
has been triggered mechanically. This, for example,
is the case if the pressure sensor has detected an
extinguishing agent even though the flooding zone is
in an idle state and no alarms are present.
Time period between the activation of the
extinguishing process from another flooding zone
and the start of the process of flooding the flooding
zone with extinguishing agent. During this pre-
warning time, people have a window of time in which
they are able to leave the flooding zone.
Determines the discharge time. This is the time
period for which the 'Flooding' state lasts. During this
period, it will be ensured that the extinguishing agent
concentration in the flooding zone prevents fire.
NOTICE! This value can be a maximum of 30 min. in
accordance with EN 12094-1.
Time period in which the pressure switch must report
an extinguishing agent flow after the opening valves
on the extinguishing agent cylinders were opened.
The ''Released' phase' state cannot be reached if the
pressure switch does not report an extinguishing
agent flow within this time. In this case, the
extinguishing system issues a fault if it is configured
with the 'Fault if pressure switch not active when
timeout expires' parameter.
