The LightSync Photo Sensor monitors light levels and transmits data across the LightSync to the lighting control panels. Each sensor has 8 individual set points for on or off control with a selectable dead-band and is programmable to control any or all relays, groups, or presets. Each sensor has a built-in adjustable filter to eliminate false triggering from lightning or other light sources. This sensor can be used for daylight harvesting to shed lighting loads or used with a dimming module to dim loads. The indoor and outdoor photocell heads convert the analog light levels to a digital form and are UV resistant.
