Occupancy Sensors, Wall Switch, PassiveInfrared, Single Circuit, 500 Watts at 120V AC, Light Almond

Standard Passive Infrared Technology requires a clear, unobstructed line of sight for detection, because it senses occupancy as movement of heat emitted from the body against the background space. A segmented Fresnel lens divides a coverage area into zones. Movement across zones is interpreted as occupancy. Excellent for small room control.
