To reduce the current consumption of the unit during the purge process, the
voltage of the purge fan can be changed as follows:
Application
Purge fan voltage [V]
For optimum purge time
13.5
For lower current consumption or lower voltage
loss during the purge process
9
… 13.4

"Aspiration fan" web help
During the localisation of the fire site, the aspiration fan may have to be
supplied with a different voltage than during normal operation.
The operating voltage of the aspiration fan must be selected in such a way
that a running time difference of min. 2 s is maintained between two
aspiration apertures located in succession during fire site localisation. As the
air flow speed is highest between aspiration aperture A and B in symmetrical
pipe systems, the shortest transport times within the pipe system result here.
The following table provides some guideline values for setting the voltage of
the aspiration fan during a localisation procedure.

Table 64:
Aspiration fan
Reducing the voltage of the purge fan only makes sense if the voltage of
the aspiration fan is less than or equal to the voltage of the purge fan.
