PASSIVE INFRARED DETECTOR QUAD ZONE LOGIC Optex improves its patented "Multifocus Optics" technology to create "Quad Zone Logic" for accurate detection of humans. Using this logic the RX-40QZ has been designed to give extremely high false alarm protection with tolerance to spot temperature changes from curtains or small animals. Optex's Optical Quad Technology uses taller detection zones divided into upper and lower areas. It detects IR energy changes in both areas and then couples them for extremely accurate detections, offering very high reliability in hostile areas.
