SUGGESTIONS FOR INSTALLATION
Do not install in the following conditions:
Ensure the sensor’s line of
sight is free from any false
alarm sources such as
bushes, trees, etc. (Pay attention to these as they may
change seasonally).
Ensure the sensors
are mounted on a
stable and firm footing.
Ensure strong sunlight or
car headlights do not shine
directly on to the receiver.
(Within ±2° from the optical
axis is not recommended).
