8.5.6 Fire-fighting function

Higher volume flow rates and pressures must be provided by the pressure booster
system in the event of a fire. When the "Fire" (J403) input is switched, all pumps start
up immediately, regardless of the protection devices fitted.
All warnings and messages output by the pump are ignored in this operating status.
(A fire alert has absolute priority.)
When the "Fire" input is restored to the original state the pumps return to their
previous operating status in line with their stop delay periods. All protective devices
and facilities then resume their operative effect.

8.5.7 Emergency power function (limitation of number of pumps)

If a building is equipped with an emergency power supply system, only a specific
number of pumps may frequently be operated simultaneously due to the limited
power supply available. This can be parameterised correspondingly in percent.
Emergency power is detected at one of inputs WSD1 to WSD3 (J 401). This is freely
configurable or can be assigned via parameter settings. When the original power
supply is restored, the pumps return to their previous operating status in line with
their start delay periods.
No automatic pump changeover is carried out as long as this function is active.
