If your lights are staying on past the programmed occupancy time delay (10 minute default from factory), the following is two possibilities of what is keeping the lights on:
-The Sensor's "Minimum On Time" has not been disabled (15 minutes by default).
-If you have a passive dual-technology sensor (PDT), the microphone in the sensor may be triggered by noise.
Both functions can be disabled via push-button programming. The instructions are available on the product programming card.
