Adjustments Continued . . .

Loosen the two thumb screws. Estimate the direction to aim the sensor and tighten the thumbscrews just enough to hold the sensor in place.

NOTE: The top screw allows the sensor to rotate side to side. The bottom screw allows the sensor to rotate up and down.

Walk through the coverage area noting where you are when the lights turn on (also, the LED will flash several times when motion is detected). Loosen the thumbscrews and readjust the sensor as necessary. Tighten the thumbscrews (finger tight) when you are satisfied with the coverage direc- tion. Keep the sensor at least 1 inch (25 mm) from lamps and keep the controls facing downward.

Adjust RANGE as needed to increase or decrease the range. Too much sensitivity may cause false triggering in some environments.

For maximum range, the sensor must be aiming straight out.

Set the amount of TIME (1, 5, or 20 minutes) you want the lights to stay on after motion is detected at night.

Release the tab on metal door to allow door to close.

Long Coverage

The sensor is less sensitive to motion directly to- wards it, most sensitive to motion across its field of view.

When mounted 8 feet (2.4 m) from the ground, you may expect the range shown below. If mounted much higher the sensor may miss objects near the ground. If mounted much lower the sensor range may be reduced.
