Local Control vs. Remote Control

The ACS 400 can be controlled from two remote control locations or from the control panel. Figure
44 below shows the ACS 400 control locations.
The selection between local control (LOC) and remote control (REM) can be done by pushing the
MENU and ENTER buttons simultaneously when the ACS100-PAN is used, and by pushing the
LOC/REM button when ACS-PAN is used.
