SYSTEM DESCRIPTION
A.
The lighting control system is a networked system that communicates via communication wire.
The system must be able to communicate with digital centralized relay panels, small distributed
relay panels, fully distributed fixture level control by relays or dimmers, digital switches,
photocells, occupancy sensors, building management control, and other system interfaces. The
intent is to centralize all lighting control into one system. Lighting control systems shall have
the capability to be remotely controlled via the intent or building wide Ethernet Lan.
B.
System software shall provide real time status of each relay, each zone, and each group.
C.
Lighting control system shall be able to be monitored by and take commands from a remote PC.
At any time, should the remote PC go off-line all system programming uploaded to the lighting
control system shall continue to operate as intended.
