What gets overridden- the turning on or the turning off?
George I am glad you asked as that is something I have wondered.
Most of the wall switch motion sensors I have installed can only be overridden to the 'off' mode. To override them to 'on' usually means getting into the adjustment section.
Here is the exception George is asking about.
210.70(A)(1)Exception No. 2: Lighting outlets shall be permitted to be controlled by occupancy sensors that are (1) in addition to wall switches or (2) located at a customary wall switch location and equipped with a manual override that will allow the sensor to function as a wall switch.
I have a related question.
110.26(D) Illumination. Illumination shall be provided for all working spaces about service equipment, switchboards, panelboards, or motor control centers installed indoors. Additional lighting outlets shall not be required where the work space is illuminated by an adjacent light source or as permitted by 210.70(A)(1), Exception No. 1, for switched receptacles. In electrical equipment rooms, the illumination shall not be controlled by automatic means only.
Does this rule out a motion sensor even if it can be overridden?
