To prevent erratic operation and/or false alarms:
Wind will not directly cause false alarms, but could cause leaves or similar objects to fly or
wave into the beams. Therefore, do not mount near trees, bushes, or other leafy vegetation.
Do not mount where the transmitter or receiver could be splashed by water or mud.
Do not mount where the unit could be suddenly exposed to a bright light, such as a floodlight or
a passing automobile’s headlight.
Do not let sunlight or any direct beam of light enter the sensing spot of the transmitter. If
needed, mount so the receiver, not the transmitter, faces the sun.
Do not mount where animals could break the beams.
