【正文】 Problems with conventional technology Threshold A F False Alarms Problems with conventional technology Threshold False Alarms No Detection a a a b b PIR39。s Amplification Processing Processing AM Signal NEXT? FM Signal PIR39。s The different amplification stages used in conventional PIR’s, cause the distortion of the detection signal and makes it impossible to utilize the full sophistication of the signal processing techniques. Without using amplifiers, all these distortions are totally eliminated providing the detector with a much better power to distinguish between real and false alarms New Relay Old Relay The use of a solid state relay instead of an electromechanical reed relay, totally eliminates mechanical problems very mon in conventional detectores, bringing to the NEXT a very high level of reliability. The End Back To Start
