Manual and Automatic Ventilation
For the ventilation of the lift shaft, the Control Unit can be
controlled by authorised persons via a manual ventilation
key switch [
Fig. 10
]. The louvre window or the ventilation
and smoke exhaustion hood are opened or closed manually
as required. The ventilation function can also be controlled
by other building control systems or by thermostats or sen-
sors installed in the shaft. To ensure the air quality in the
lift shaft, the smoke exhaustion flap can be opened via an
optional CO2 air quality sensor if necessary.
Approvals (abZ /aBG)
The use of a lift smoke exhaustion system, which normal-
ly keeps the „smoke exhaustion opening“ of the lift shaft
closed for the purpose of energy saving, as required by
building law, requires proof of use in accordance with the
model building regulations (MBO). The

system possesses this proof in the form of a combined „ge-
neral building supervision approval“ (abZ) with a „general
type approval“ (aBG).

The ventilation switch inputs of the
LSF 7000
are not intended as inter-
faces for devices for the detection and
evaluation of the shaft movement or the
presence of persons in the lift shaft.
