I have 8 lithonia 4' LED wraparound lights in my basement, being controlled by 2 lithonia motion sensors model msx12 , mounted at opposite ends. my issue is the lights come on periodically when no one is around. fortunately i have the timer set low so they go off soon........motion sensors are wired in parallel......called lithonia , they dont have any idea why this is happening. basement ceiling is only 7ft, is that to low for motions, i wouldnt think so.....any clues?
