Pet-Immune PIR Motion Detector


Pet-Immune Motion Sensors:IRP-29 Series

Designed to prevent false alarms triggered by pets or small animals, IR-31 is a microprocessor controlled PIR Motion Detector that offers quality detection and pet immunity up to 20 kilos/50 cm. The advanced Adaptive Digital Signal Processing (ADSP) algorithms in IR-31 guarantee high performance in sensitivity and reliability. The sensitivity levels of IR-31 can be adjusted to suit different premises. IR-31 leverages Climax’s industry-leading RF technologies to deliver super speed signal transmission and extensive communication range.

Easy and flexible to install, IR-31 sends regular supervision signals to check system integrity and has tamper-proof design to prevent the opening or removal of its housing. Technologically advanced and aesthetically appealing, IR-31 stands out as a broadly applicable device ready to make your home or business safer and smarter.
