EQUIPMENT
A. Lighting Control Panels: Lighting control system shall consist of a master and remote panel(s)
controlled by a 32-channel digital time clock (DTC) that controls and programs the entire lighting
control system. The DTC shall supply all time functions and accept external inputs. The DTC
shall accept local control and display prompts to the user on an 8 line 21-letter display. The DTC
shall accept user input from keypad pushbuttons, connected computer, modem, Ethernet or
internet devices. All commands shall be in plain English. User help information shall display on
the DTC screen.
B. Digital Switches: All digital switches shall communicate via RS485, CAT5 patch cable with RJ45
connectors. Contact closure style switches are not acceptable. Any digital switch button function
shall be able to be changed locally (at the DTC or a PC) or remotely, via modem, Ethernet or
internet device. Refer to single line diagram for wiring details. Switches which cannot be
programmed remotely shall not be acceptable.
C. Photocells: Exterior (PCO) or interior (PCI) photocells shall provide numeric readout on the DTC display
in numerical values corresponding to foot-candles values. Each photocell shall provide a minimum of 14
trigger points. Each trigger point can be programmed to control any field configurable relay or zone. Each
trigger point shall be set through DTC, locally or remotely. Photocells that require the use of set screws or
manual adjustments at the photocell control card shall not be acceptable.
D. Accessory Devices: Accessory lighting control system interfaces to include a dry contact input interface,
