JLS-LL-EFS07-AUX is PIR sensor combines occupancy sensing with photocell. When used with 0-10V dim-to-off LED drivers, it enables any lighting manufacturer to deliver sensor-equipped fixtures with minimal engineering effort. It operates on 12V DC which can be supplied by a LED driver, which will save OEM cost on manufacturer side. Different modes can be selected according to different applications through JLS-LL-RM51 IR remote controller. The integrated photocell can switch the lights on and off for dusk to dawn control, so that lighting remains on overnight even without motion detection. Under daylight harvesting mode, the auto-calibration function can control the amount of electric light by measuring the overall combined natural and electric light to achieve the desired light level working with JLS-LL-SC01/SC02 receptacle.
