Remote Control Multi-Drop Operation
Multi-Drop Functionality can control up to 4 units of the same type.
Types cannot be mixed.
At start up, the Panel will scan the full address range looking for
units and assigning a unit number to the units found (1 for the first,
2 for the second etc).
After the address scanning is complete, the display will show the
Main menu for the first unit found. Operation from this point on is
the same as that described for the particular unit type in the single
drop mode.
The Panel will continue to monitor the fault status of all units
found but can only display the settings and meter readings for one
unit at a time. To select a different unit, press the function key and
then use the up/down keys to select another unit number. The
address of the newly selected unit is shown at the far right side of
the display. Pressing the enter key takes you to the Main menu for
that unit.
