APPENDIX 3
Installation Tips
The R2E-100 active infrared pattern is made up of two narrow, side-by-side detection zones that project at slightly offset angles. See Figure 1 for
an illustration of the two detection zones in a typical installation. Figure 2 shows the relative position of the two zones or "spots" at a distance of 48"
below the sensor (as viewed from the floor).
For best performance, adjust the position of the circuit board assembly inside the mechanical enclosure so that both zones project slightly in front
of the door handle (see Figure 3). Refer to Section 8 of the User's Guide for detailed instructions about changing the angle of the circuit board
assembly.
Mount the mechanical enclosure to the wall or door header above the door so that both detection zones are located in the desired left-right position
relative to the door handle (see Figure 4). Ideally the detection zones will cover the full width of the door handle (left-right) to eliminate any "holes"
along the door handle.
NOTE: DO NOT DRILL A HOLE IN THE DOOR HEADER FOR THE HARNESS OR INSTALL ENCLOSURE SCREWS UNTIL THE DESIRED
LEFT-RIGHT POSITION OF THE SENSOR HAS BEEN TESTED AND CONFIRMED.
TROUBLESHOOTING
If the sensor goes into activation upon power-up, it is most likely the result of one of two parameters requiring further adjustment. First, check
the angle setting of the circuit board assembly in the clips (refer to Section 8 of the User's Guide). If the sensor is angled too closely to the
face of the door, the door handle will likely intersect the detection zone, thus causing a false detection. Next, turn down the RNG potentiometer
(counterclockwise), which will decrease the depth of the detection zone. In applications where there is a highly reflective background (e.g. smooth
tile or concrete floor), the RNG potentiometer can also be used as a sensitivity adjustment.
