No trigger body movements
Figure 8 – no trigger
No trigger body movements are body movements which are too small to be recognized as valid body movements to trigger the detector.
In the example, shown by figure 9, a body walking into one side of the infrared beam zone, then back out the same side of the infrared beam zone will not trigger the detector. A body moving from position 1 to 2, into the infrared beam zone, will only create pulsing. A body moving from position 2 back to position 1 or from position 2 to position 3 (out of the same side of the infrared beam zone) may create further pulses but will not trigger the detector. This also applies if the body is moving in and out of the infrared beam zone from the other side.
