Example of pre-activation / activation of the flooding zone
The parameters 'No. of zone requests for EXTINGUISHING PRE-ACTIVATION'
and 'No. of zone requests for EXTINGUISHING RELEASE' determine the
conditions that must be met for the flooding zone to transfer to the state ''Pre-
activated' phase' or ''Activated' phase'.
The following default settings are pre-configured for the 'Causes' function:
Number of requests
1
0
2
1
Meaning
The flooding zone switches to the state ''Pre-
activated' phase' when at least one request is
transferred from the assigned 'Zone' elements at
time t following a transition to the state ''Pre-
activated' phase'.
Following a transition to the ''Activated' phase' state,
the number of requests from the assigned 'Zone'
elements is not evaluated if the parameter value is
set to 0.
Regardless of quantity, requests sent after a
transition to the state ''Activated' phase' cannot
trigger the flooding zone's transition to the state
''Pre-activated' phase' in this example.
The flooding zone switches to the state ''Activated'
phase' when at least two simultaneous requests are
transferred from the assigned 'Zone' elements at
time t following a transition to the state ''Pre-
activated' phase'.
The flooding zone switches to the state ''Activated'
phase' when at least one request is transferred from
the assigned 'Zone' elements at time t following a
transition to the state ''Activated' phase'.
