Optex RX-40PI(C) Wired Indoor PIR Detector with Pet Immunity

Description

The
Optex RX-40PI is a residential pet immune passive infra-red (PIR) motion detector
featuring a 40' x 40' coverage area.
Optex improves its patented Multi-focus Optics technology to create Quad Zone Logic for accurate detection of humans. Using this logic the RX-40PI had been designed to to give extremely high false alarm protection with tolerance to spot temperature changes from curtains or small to medium size 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 with for extremely accurate detections. Offering very high reliability in hostile areas.
Quad Zone Logic & Multi-Focus Optics:
Optex has 2 different detection logics, Quad Zone Logic and Multi-Focus Optics. Each logic creates high vertical density detection zones by original optical technology to prevent false alarms. Normally, a detector uses twin elements to create two detection zones but Optex's detectors create an extremely high vertical zone density, two or three times the size of that in conventional PIRs. These taller zones capture the entire body mass of a person and enable detection of the smallest temperature contrast between them and the background.
