LightSync Photo Sensor 4

LightSync Digital Photo Sensor 4

Models: LSPSC4-P, LSPSC4-R

The LightSync Digital Photo Sensor 4 incorporates a space-saving 4 head controller in 1 module. As with our standard photocell controller it monitors the light levels and transmits the  data across the LightSync Digital data line 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 any or all relays, groups, or presets. Each sensor has a built in adjustable filter to eliminate false triggering from lightning or other sudden light sources. 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.
