JUMP TO FULL CODE CHAPTER
Occupant sensor controls in warehouses shall comply with Section C405.2.1.2. Occupant sensor controls in open plan office areas shall comply with Section C405.2.1.3. Occupant sensor controls for all other spaces specified in Section C405.2.1 shall comply with the following:
- They shall automatically turn off lights within 20 minutes after all occupants have left the space.
- They shall be manual on or controlled to automatically turn on the lighting to not more than 50-percent power.Exception: Full automatic-on controls shall be permitted to control lighting in public corridors, stairways, restrooms, primary building entrance areas and lobbies, and areas where manual-on operation would endanger the safety or security of the room or building occupants.
- They shall incorporate a manual control to allow occupants to turn off lights.
