Note: If at any time the red Status indicator begins to flash steadily, the System has entered a Lockout
condition. See

6.3.4 Optical Alignment Procedure with Mirrors
EZ-SCREEN LS sensors may be used with one or more corner mirrors for guarding more than one side of an area. The
MSM-... and SSM-... rear-surface glass mirrors are rated at 85% efficiency. Thus, excess gain and sensing range are
reduced when using mirrors; see Use of Corner Mirrors, under
Mechanical Installation Considerations
on page 28.
During any adjustments, allow only one individual to adjust any one item at any one time.
In addition to the standard optical alignment procedure, verify:
1. The emitter, receiver, and all mirrors are level and plumb.
2. The middle of the defined area and the center point of the mirrors are approximately the same distance from a
common reference point, such as the same height above a level floor.
3. There are equal amounts of mirror surface above and below the defined area such that the optical beams are not
passing below or above the mirror.
Note: A LAT-1-SS Laser Alignment Tool is very helpful by providing a visible red dot along the optical axis.

6.3.5 Remote Fixed Blanking
On cascade models, fixed blanking is available to, in effect, "disable" beams that would otherwise be continually blocked by
a stationary object. One or multiple areas within an EZ-SCREEN LS sensor pair may be "blanked out," with a minimum of
one beam between two blanked areas. The first sensing beam (CH1 synchronization beam) at the display end of sensor
must remain clear (cannot be blanked); any other beam may be blanked. All beams of a fixed blanked area must remain
blocked during operation in order for the OSSDs to remain ON.
The Remote Fixed Blanking feature can be used on an EZ-SCREEN LS cascade receiver as a stand-alone system or in a
cascaded system. A DELSEF-81D cordset used with a EZA-RBK-1 Remote Blanking Key Switch or a RDLS-8..D cordset
with a user-supplied switch and indicator provides a convenient means to program the blanked area. The remote
programming is effective on all receivers in the cascaded systems (for example, multiple areas can be blanked on different
sensor pairs). After programing, the DELSEF-81D cordset and EZA-RBK-1 Remote Blanking Key Switch can be removed
