MOTION DETECTION
6.1 Adjust the Motion Sensor Orientation
1. To make any needed adjustments to the Motion Sensor (PIR) access the back panel of the NPVD by unscrewing the two
thumb screws.
2. The motion sensor is located to the far left side of the panel as you are facing the back of the NPVD. See
Figure 6
.
3. Adjustments can be made to the Sensor by rotating the adjustment wheel in either direction by moving it clockwise or
counter clockwise. The sensor can also be moved in an up and down orientation by unscrewing slightly the steering yoke
and sliding the sensor up or down then retightening.
4. The standard PIR detects motion by sensing left to right or right to left in a horizontal fashion. To change the orientation of
the sensor simply begin adjustments as explained in step 3 until the sensor begins to detect in the field of view desirable.
5. The following chart may be helpful when determining the pattern of movement most desirable for the area the NPVD is
installed in.
