Description
When the NAPCO Adaptive Microwave/PIR Detector powers up, it's initialized in the first, most sensitive mode of its 12 sensitivity modes, enabling it to sample prevailing environmental conditions. Faced with hostility or tranquility, the Adaptive detector automatically selects the most appropriate detection mode accordingly, optimizing both intruder catch and stability. Each time the sensors detect a stimulus strong enough to generate a signal, but insufficient in strength to indicate an alarm, the detector will automatically change sensitivity modes, effectively widening the gap between the detected signal and its alarm threshold. Therefore, environmental disturbances, those that register by the PIR and/or microwave sensor, are better tolerated and the threat of false alarms or nuisance alarms is dramatically reduced, far surpassing the performance of conventional dual technology devices. And, because a dynamic Adaptive Detector literally adjusts to its surroundings minute-by-minute, once disturbances quiet, e.g., the space heater turns off again, the air conditioner stops blowing the blinds, power stops browning-out, animals vacate - the intelligent detector again escalates its sensitivity, mode by mode - so the premises always enjoys the greatest level of fast intruder-catch detection and false alarm protection possible. The Napco Adaptive Sensor is the most forgiving sensor available because it is so smart and makes the sensitivity and critical range adjustments an experienced alarm professional would, if one were standing by, 24-hours a day, seven days a week to make them. Any activity beyond the unit's protected area, detected by the microwave section is also automatically compensated for. The unit even actively tests both its channels (PIR and Microwave), regularly activating each, to make sure it is on-the-job, performing to specification.
