Optex Passive Infrared Detector

Optex Passive Infrared DetectorMade By Optex CompanyPet Immunity PIR Motion DetectorPassive InfraredThe RX-40PI rejects false alarms caused by spot temperature changes such as small to medium sized animals, air conditioners, or moving curtains. Utilizing Quad Zone Logic, the RX-40PI couples signals from its 78 detection zones to determine the size of its target. Its high quality spherical lens and its dense detection pattern give the RX-40PI Catch and Pet Immunity that is superior to other single technology detectors. Sealed housing prevents drafts and insects from reaching the pyro element. RX-40PI's Quad Zone Logic recognizes humans and ignores most small animals (applies to animals 0 to 16 inches in height), providing multi segmented detectionzones over the detection area. A durable spherical lens obtains an accurate focal length for each detection zone and maximizes the performance of Quad Zone Logic. These signals are further analyzed by the “ECO” chip and signal processing circuit for accurate detection of humans and avoidance of most small animals. ECO chip includes temperature compensation circuit which controls sensitivity to improve stability against changes in environmental conditions Additional Features RFI Protection No alarm at 20 V/m from 100MHz to 1 GHz
