ADJUSTING THE VERTICAL ANGLE

For best performance, install detector parallel to the ground.
Decide the detection length. To change the detection length, adjust the flap and plate
positions. Refer to the 2-2, 2-3 for the details.
Perform walk test to
ensure detector is
parallel to the ground.
If the detection length is
shorter than that which was
setup (refer to page 7), change
the detector angle upwards.
If the detection length is longer
than that which was setup
(refer to page 7), change the
detector angle downwards.

• If the base of the unit is already parallel to the ground, do not change the detection length
by tilting the main unit up or down. Refer to 3-1 for the details.
