Configuring flooding zone control
Description
If the parameter is activated, the system issues a
fault if the pressure switch is not active after the
timeout period has expired.
After the timeout period has expired, the
extinguishing system switches to the ''Released'
phase' state in all cases.
If the parameter is activated, the system does not
trigger the flooding of the flooding zone if the
extinguishing agent supply for the flooding zone is
mechanically locked.
If the parameter is activated, the system switches to
the 'Not ready' state if the 'Reset' button has been
pressed and causes for the activation of
extinguishing are still present.
Possible causes are:
● Automatic activation: Alarms from automatic fire
detectors in the flooding zone are still active
● Manual activation: an actuated manual call point
which has not been manually reset yet
● Active pressure switch in the extinguishing agent
supply to the flooding zone
● Active signal for an external trigger by another
flooding zone
When the parameter is activated, the system will
indicate an error if the 'Emergency hold' switch is
actuated while the flooding zone is in the 'Quiet'
state.
