Abstract: An occupancy sensor is provided with a separable override unit to selectively override the operation of the occupancy sensor at designated times and for selected time intervals. The occupancy sensor includes a light sensor for actuating the occupancy sensor and a light assembly when the ambient light is below a predetermined level and to deactivate the occupancy sensor when the ambient light is above a threshold level. The override unit having a light source is removably attached to the occupancy sensor. The override unit is coupled to the occupancy sensor to emit light to actuate the light sensor of the occupancy sensor, thereby preventing the occupancy sensor from being actuated regardless of the light level in the surrounding areas. A control unit is operatively connected to one or more override units for selectively controlling the normal operation of the occupancy sensor.
