This system allows specific on/off setpoints based on the required level of illuminance. Parking lots and walkway luminaires, not on security lighting circuits, are scheduled off at a predetermined time in the evening with the LI panel’s time clock. Canopy lighting turns on at 20 footcandles, walkway lighting at 10 footcandles, and parking lot lighting at two footcandles. All security lighting turns off at dawn. A dataline switch is located in the reception office area for manual override of all exterior lighting groups.
