Interlogix NX-481 Indoor SAW PIR Pet Immune Motion Sensor.
A motion sensor (passive-infrared or PIR) detects movement within a specific area by sensing the infrared energy emitted from a body as it moves across the sensor's field of view (FoV). When this motion is detected, the sensor transmits an alarm signal to the control panel.
Use this motion sensor to protect locations where door/window sensors are impractical or not needed. For example, use a motion sensor to protect large areas or open floor plans. Motion sensors also provide backup protection for door/window sensors.
The Pet Immune SAW PIR (NX-481) utilizes advanced signal processing, a new custom designed lens, and a new custom designed sensing element. The combination of these improvements provides false alarm immunity for pets with a combined weight of up to 40 pounds while still providing superior human catch performance.
