REFLECTIVE SURFACE
Increasing the size of the test piece to block
extra beams causes a blocked condition.
The size of the test piece required to do this
determines the actual resolution.
At the midpoint of the defined area, a test piece (represented by the darker
sircle) with the specified system resolution does not cause a blocked
condition, due to an optical short circuit. Alignment indicator LEDs are ON
green and the OSSDs are ON.
For 0.1 to 3 m (4 in to 10 ft) Operating range: d = 0.13 m (5 in)
For Operating range > 3 m (> 10 ft): d = 0.0437 x R (m or ft)
Figure 15. Adjacent Reflective Surfaces
At the midpoint of the defined area, a test piece (represented by the darker circle in Figure 15 on page 33) with the specified
system resolution does not cause a blocked condition due to an optical short circuit. Green Alignment indicator lights are
On and the OSSDs are On. Increasing the size of the test piece to block additional beams causes a blocked condition. The
size of the test piece required to do this determines the actual resolution. Use the table below to calculate Dpf or Factor "C"
when a shiny surface causes an optical short circuit.

5.1.6 Use of Corner Mirrors
EZ-SCREEN LS may be used with one or more corner mirrors. Mirrors are not allowed for applications that would allow
undetected personnel access into the safeguarded area. The use of glass-surface corner mirrors reduces the maximum
specified emitter/receiver separation by approximately 8 percent per mirror, as follows:
