Section 7
Adjusting Detection Pattern
Adjust the detection pattern according to the following
diagrams:
1. Pattern Angle Adjustment.
• The body of the sensor can be rotated from
0º to 5º (3 steps).
2. Pattern Width Adjustment.
Mask Adjustments for single and/or double doors.
Detection pattern will vary according to
objects, material, color and speed.
Section 8
Verification of Operation
1. After mounting, setting parameters and applying
power, walk test unit to verify detection pattern.
2. If the door does not operate properly, recheck the dip
switch settings and pattern adjustments.
3. After rechecking, if there is still a problem, adjust the
sensitivity.
• Adjust high (clockwise) to increase sensitivity.
• Adjust low (counter-clockwise) to decrease
sensitivity.
*****EXTREMELY IMPORTANT*****
After final set-up, test unit(s) completely to ensure that
proper coverage has been achieved (width, depth and
location of the pattern must be tested).
After the installation and operational check of the
system:
1. Place the proper labels on the door per ANSI/BHMA
A156.10 or any other applicable standard.
2. Instruct the owner of the door system operation and
how to test it. This should be checked on a daily
basis.
3. Instruct the owner on what to do if the door or any of
its components become damaged.
4. Strongly recommend to the owner that the complete
entry be inspected twice a year as part of the service
agreement.
