D.4.3) Minute Adjustment of depth coverage
Adjust the minute setting to move the detection area in close to the doors. Adjust the detection area
by sliding the minute area adjustment knob.
Note: Do not over tighten the adjustment knob
The direction where detection area is tilted toward the door is regarded as minus (-). There are 9
adjustment positions within the range between –4 to +4 degrees.
If the mounted height is 8 ft, each adjustment position (1 degree) causes the detection area to
move about 2 inches.
The adjustment knob is factory set to 0 degrees.
CAUTION:
When detection area is tilted toward the door, the bottom edge of the header can block the
sensor pattern if the sensor is installed too high on the header. Refer to page 7.
Do not use the adjustment knob to widen the detection area.
D.4.4) Adjusting for Width Coverage
The width coverage is achieved in seven increments as shown below. Up to six increments of
detection width can be turned off, resulting in a reduction in coverage for the entire width. This
may prove useful for the narrower openings on single slide or swing doors. All detection
areas except Area 4 can be turned off (see Figure 5). Under normal conditions, all seven areas
should be used. If any detection area zone is turned off, it will be necessary to check the
detection area to be sure the correct ANSI Standard is achieved.
Note: Sensed areas are not true rectangles but rectangular approximations. Pattern size will be
affected by floor surface color and texture.
