Axis 2N Lift8 Brief Manual page 3

The machine room audio unit is intended for installation in the machine room or as an
intercom solution located in the reception.
Connector description
On the right side under the cover there are 3 connectors:
Bus connection
Loosen the screws to the right and open the connector cover. There is just one connector
under the cover: a bus connector. Pull out the terminal from the connector, connect the
wires and replace the terminal. Make sure that the polarity is maintained.
Warning
Connection to different, e.g. higher-voltage, cables leads to damage or

destruction of the audio unit.
Maintain polarity while connecting the audio unit to avoid audio unit error.

Caution
The audio unit is powered via a 2-wire bus. Disconnection of these wires

results in the audio unit switch-off.
Adress configuration
There is a group of jumpers under the
transparent front cover. Do not use any of
them if the machine room is only intended
for the given lift. The audio unit identifies
itself as the machine room for the given lift.
If the machine room is to be shared by
multiple lifts, configure the corresponding
pins 1–8 for the lifts to share the machine room (numbered 1–8 from left to right 1–8).
Note
This audio unit is always configured as the machine room and cannot have a

different location.
