I have a question that is not covered by the National Electrical Code, but is mentioned in the Life Safety Code. I'm in charge of the facilities electrical of a large manufacturing facility and we are in the process of installing occupancy sensors throughout the building. It was brought to my attention that it is against code to put stairwell lighting on occ sensors.
After doing a lot of research, I concluded that occ sensors are allowed in the path of egress for non-emergency powered lighting, as long as the sensors fail safe.
What are your thoughts on this? I have been unsuccessful in finding any information in the cutsheets of the occ sensors we use indicating whether or not they fail safe (as in the relay fails closed).
