Cautions when using the outdoor photoelectric beam sensor (Daily maintenance)
1. In areas where there are trees or weeds, the photoelectric beams may get obstructed by overgrown branches or leaves.
As this may cause erroneous detection, be sure to trim down leaves and branches according to the growth of the plants.
Furthermore, the photoelectric beams may get obstructed by swaying branches or leaves due to wind. Keep in mind the swaying of leaves
and branches when trimming them.
2. Bine plants may wrap around the photoelectric beam sensors causing erroneous detections. Therefore, be sure to prune such plants
regularly.
3. Insects, bird droppings, or other natural phenomena may also soil the sensors causing erroneous detection. Be sure to clean the sensors
regularly.

In order to use these sensors correctly, read thoroughly this instruction manual and select the mounting
position and protection distance.
4.45" (113 mm)
7.24" (184 mm)

B: Coverage of light beam
Approx. 4ft (1.2 m)
Approx. 8ft (2.4 m)
Approx. 16ft (5.0 m)
As these sensors are designed to detect humans, install so that the center of the sensors are at a height of
approximately 2.6ft (0.8 m) from the ground when installing both on a wall and on a pole.
Approx. 2.6' (0.8 m)
As the infrared light leaves the transmitter, it expands into conic shape light beams.
The optical axis is in the center of the light beams. Arrange the reflector so
that the device on the opposite side is in the center of the light beams.
