'Zone'element – parameters in the 'Details' tab
The following table describes the parameters in the 'Extinguishing activation
criteria' area of the 'Details' tab.
You will find information about all other parameters in chapter 'Configuring the
'Zone' [➙ 162]'.
Parameters Value Description
'Enabled for extinguishing' On/off
The parameter determines whether the
'Zone' element can be used as a cause
for the pre-activation or triggering of a
flooding zone.
When the parameter is activated, the
'Zone' element can be assigned with the
causes function 'Automatic release' for
a flooding zone.
'Request 'Automatic exting.
pre-activation''
0 ... n
n = Number of fire detectors or signal
inputs within a 'Zone' element
Top line: Minimum signal quantity for
danger level 2
Bottom line: Minimum signal quantity for
danger level 3
The parameter determines the number
of signals for danger levels 2 and 3 that
the detectors must transfer within the
zone so that the 'Zone' element can
transmit a pre-activation request for the
flooding zone in question to the
associated 'Extinguishing sector control'
element.
The request is evaluated within the
causes function 'Automatic release' for
the flooding zone in question.
Depending on the configuration of the
function, several zones may be required
to transmit a request before pre-
activation can actually be triggered. You
will find more information on this in
chapter 'Causes functions [➙ 359]'.
'Request 'Automatic exting.
release''
The parameter determines the number
of signals for danger levels 2 and 3 that
the detectors must transfer within the
zone so that the 'Zone' element can
transmit a extinguishing trigger request
to the associated 'Extinguishing sector
control' element.
The request is evaluated within the
causes function 'Automatic release' for
the flooding zone in question.
Depending on the configuration of the
function, several zones may be required
to transmit a request before
extinguishing can actually be triggered.
You will find more information on this in
chapter 'Causes functions [➙ 359]'.
