Normal mode / paging mode:
These jumpers (JP2) allow selection of the operation mode between normal and paging
mode. The unit is default configured to be used in paging mode.
Paging mode (default)
Normal mode
Paging mode: At power-on, all relays will be activated and will be switched
to background music mode. In case of power interruption (emergency
situation) the relays will return back to their idle state. This configuration is
recommended when using the ARU20x in music / paging announcement systems.
