You may not be allowing the unit time to
complete its warm-up period. Stand well out
of the detection range and wait (the warm-
up period should never exceed 5 minutes).
Occasionally, winds may activate the sensor.
Sometimes passages between buildings
etc. can cause a “wind tunnel” effect.
Ensure the unit is not positioned so as to
allow detection of cars/people using public
thoroughfares adjacent to your property.
Ensure that the unit is mounted securely,
even the slightest movement can result
in a false detection.
