INTRODUCTION
The ARC Plus remote monitoring and control system takes advantage of the scalability of TCP/IP to provide site-to-
site control, central monitoring and/or distributed access to hundreds of sites. Users can manage the system via
web browser, smartphone, tablet and optional telephone and software interfaces, in any combination. Multi-site
ARC Plus networks allow site-to-site control from the front panel of any ARC Plus or ARC Plus Touch, and
automatic coordination of multiple facilities via onboard macros.

network (Click or turn to

power is on.
