Microwave Signal Processing  
The DS820 and DS835 Series Detectors provide  
immunity to false alarms caused by pets. Passive  
Infrared and microwave processing provides excellent  
catch performance with freedom from false alarms.  
Pattern recognition circuitry identifies and ignores  
repetitive false alarm sources. Adaptive processing  
adjusts to background disturbances. This helps to  
reduce false alarms while maintaining catch  
performance.

Motion Analyzer II Processing  
Motion Analyzer II uses multiple thresholds and timing  
windows to analyze timing, amplitude, duration, and  
polarity of signals to make an alarm decision. It will  
not alarm on extreme levels of thermal and  
illumination disturbances caused by heaters and air  
conditioners, hot and cold drafts, sunlight, lightning,  
and moving headlights. Provides three sensitivity  
settings.

Functions  
Test Features  
Signal Processing  
Externally visible alarm LED flashes to indicate a  
trouble condition.  
Uses passive infrared and microwave technologies to  
provide an alarm condition when both fields of  
protection are simultaneously activated. Alarm signals  
must meet the signaling requirements of both  
technologies to activate an alarm. Adjustable PIR and  
microwave sensitivity.  
Draft and Insect Immunity  
The sealed optical chamber provides immunity to  
drafts and insects.
