2.4 External signal generator
The external signal generator (order no.
20162) for transmitting the acoustic warning
to other rooms can be connected if required.
2.5 Potential-free switch contact
As an option, an additional board with a
potential-free contact (order no. 80072)
can be connected to the central control
technology of the building. For connection
see the leaflet on potential-free contact.
In the event of backwater or a problem,
every alarm is sent via the potential-free
contact. During flap test (key function
"flap test") an alarm is given via the po-
tential-free contact when the flap reaches
the final position "closed".
2.6 Pump connection
The pump has already been installed and
only has to be connected (see 2.2).

extensions are available (art. no. 80889
probe, art. no. 80890 pump). The maxi-
mum cable length of 30 m must not be ex-
ceeded.
