RADION PIR and RADION PIR C are high performance, Passive infrared (PIR) based motion sensors that use advanced signal processing to provide superior catch performance and unsurpassed false alarm immunity.
PIR Signal Processing
Motion Analyzer II uses multiple thresholds and timing windows to analyze timing, amplitude, duration, and polarity of signals to make an alarm decision. The detectors tolerate extreme levels of heat and light from heaters and air conditioners, hot and cold drafts, sunlight, lightning, and moving headlights. There are three sensitivity settings.
Test Features
Externally visible, LED indicates alarm each technology independently.
Pet Immunity
The detector is able to distinguish between signals caused by humans and signals caused by pets such as a dog up to 13 kg (30 lb) or two dogs at 27 kg (60 lb) or up to ten cats. This provides immunity to false alarms while maintaining proper catch performance of human targets.
Draft and Insect Immunity
The sealed optical chamber provides immunity to drafts and insects.
Temperature Compensation
The sensor adjusts its sensitivity to maintain consistent catch performance at critical temperatures.
Battery Life Extension feature (PIR and TriTech)
In the normal operating mode, an alarm can be transmitted only after three (3) minutes have passed since the previous alarm restoral. This 3 minute lockout time reduces unnecessary RF transmissions in high traffic areas, thereby extending battery life.
