The 'Operation' task card can be used to adjust global settings for extinguishing
under the 'Global extinguishing configuration' element.
'Global extinguishing configuration' – parameters in the 'Overview'
tab
Values Description
On/off The parameter determines whether the actuator on the extinguishing
agent cylinders is activated when the pressure switch transmits a
flow of extinguishing agent.
This is designed for faults when a flow of extinguishing agent is
detected and the extinguishing system is in the 'Quiet' state.
On
The parameter determines the dependency between the activation
criteria for zone requests to activate extinguishing and the criteria to
achieve the 'PRE-STAGE' and 'MAIN STAGE' events within a zone.
You will find information on configuring the zone requests for
activating extinguishing in chapter 'Configuring automatic
extinguishing activation [➙ 349]'.
You will find information on interpreting the zone requests within
flooding zone control in chapter 'Causes functions [➙ 359]'.
The parameter is switched on
The following conditions must be met for a 'Zone' element to transmit
'Request 'Automatic exting. pre-activation'' and 'Request 'Automatic
exting. release'' type requests:
● The corresponding criteria under 'Extinguishing activation criteria'
must be met and
● The 'Zone' element must transmit the event 'PRE-STAGE' or
'MAIN STAGE'.
Note: The request is stored temporarily for as long as the 'Zone'
element transmits one of the events. This also applies when the
criteria for the request under 'Extinguishing activation criteria' are no
longer met. The system does not withdraw the extinguishing request
until the 'Zone' element no longer transmits a 'PRE-STAGE' or 'MAIN
STAGE' event.
Off The parameter is switched off
A 'Zone' element transmits a 'Request 'Automatic exting. pre-
activation'' or 'Request 'Automatic exting. release'' type request when
the criteria for the request under 'Extinguishing activation criteria' are
met. The system withdraws the request when the criteria are no
longer met.
This means that the extinguishing request does not depend on
whether the 'Zone' element is also transmitting a 'PRE-STAGE' or
'MAIN STAGE' event at the same time.
