Adjusting The Vertical Angle - Optex HX-40 Installation Instructions Manual

2-2

ADJUSTING THE VERTICAL ANGLE

For best performance, install detector parallel to the ground.
Decide the detection length. If you choose 9.0 m/5.5 m/4.0 m, mask the unnecessary lens with
masking seals. Refer to the 1-5 for the details.
Perform the walk test to check
if detector is parallel to the
ground.
If the detection length is
shorter than the designated
one (refer to page 5), change
the detector angle upward.
If the detection length is
longer than the designated
one (refer to page 5), change
the detector angle downward.
Caution>>
If the base of the unit is already parallel to the ground,
• Do not change the detection length by tilting the unit up or down. Detection length should
be adjusted with masking seal. Refer to 1-5 and 2-1 for the details.
Example (the ground is level)
0° is the right setting for 3.0 m
(9'10") height installation.
Adjust 1 click (2.5° upward) for 2.5 m
(8'2") height installation.
12.0 m (40')
* This is the case to have 12 m detection length.
If the detection length is
equal to the designated
one, adjustments have
been completed.
