Technical Tips:
Lights Turn On for Unknown Reasons
1. Lights may turn on occasionally 
during rain, snow and windstorms 
because the sensor detects 
changes in temperature. 
Solution: mount sensor in 
protected area.
•  If false detections constantly 
occur, reduce sensitivity (turn 
counterclockwise) until the 
problem stops.
2. Tilt the sensor lower; it may 
register movement from distant 
objects.
3. You may not be aware of animals 
triggering the sensor. Create an 
“Animal Alley” by aiming sensor 
or masking the lower portion of 
the lens with opaque weather-
proof tape to reduce triggering.

4. Although it is surge and transient 
protected, the sensor may 
occasionally turn on during 
extreme voltage surges.
5. A possible source of “mysterious” 
sensor activations are strong 
local radio signals. Check for 
nearby CB, Ham, VHF radio 
transmitters or cellular 
telephones. These signals may 
activate the sensor, but will not 
do permanent damage.
6. Check all the solutions 
 mentioned under “Lights Turn 
On and O.”
7. Check items #2, 4, 5, 6, and 7 
under “Lights Do Not Turn O.”
