Sensing Mode Configurations
In opposed-mode configuration, the emitter and receiver are
mounted opposite from each other to form a single beam (see
Figure 3-3). Opposed-mode configuration can be combined with
vertical corner mirrors for perimeter-guarding applications, as
shown in Figure 3-4 and described in Section 3.3.6.
Access-Guard Configurations
In access-guard configuration, the emitter and receiver are
used with two angled mirrors to create multiple beams from one
EZ-SCREEN Point System – in effect, forming a vertical light
grid using one beam. The ACCESS-GUARD kit is available for
constructing this configuration (see Figure 3-3 and Section 2.1).
