PROBLEM 3: Door operates by itself
CAUSE 1: Sensitivity too high
SOLUTION 1: Turn down sensitivity
CAUSE 2: Another sensor is too close by
SOLUTION 2: Change the frequency to each sensor
CAUSE 3: Sensor detects the door movement
SOLUTION 3: If the indicator LED is an Orange color,
adjust the pattern depth angle away
from the door
CAUSE 4: There is a cloth mat in the detection
pattern
SOLUTION 4: Turn the sensor power off and then on
again, and allow it 10 seconds to
reprogram
CAUSE 5: Detection pattern too far in front of the
door, detecting people passing by
SOLUTION 5: Adjust the detection pattern - move it
closer to the door
CAUSE 6: The condition of the monitored area is
varying (i.e., dusty, dirty, snow)
SOLUTION 6: The condition of the detection zone can
change due to heavy dust or dirty, heavy
snow or footprints being left in fresh
snow. This will cause the door to open
sometimes. Set the Presence Timer to a
short time. (See Section 5)
