Provided with robust IP66 rated housing and UV protection, the Infrascan is designed for ongoing performance in harsh conditions. The Infrascan detects movement up to 18m at 110degrees with adjustable sensitivity, lux level and time delay, for control of LED or other lighting loads. Suitable for residential or commercial applications. The industry benchmark for outdoor motion sensors since 1984. New look, modern components, same trusted class-leading robustness. Manual Override Feature While the sensor is designed to switch a light on for a defined period set by the timer trimpot, the 750WPR5 can also be put into an override mode that keeps the light on for 8 hours. To do this, from its automatic operation mode, simply turn the wall switch controlling the sensor OFF-ON-OFF-ON within a 2-second period. To cancel out of this mode prior to the 8 hours expiring, simply turn the wall switch OFF-ON within 2 seconds Features PIR Motion detection up to 18m @ 110 degrees. Modern components and manufacturing processes. High reliability.
