11.0 Maintenance
At least once a year, check the range and coverage in
accordance with Section 9.1 Memory, Day Mode, Night Mode,
and Walk Test. To ensure proper daily operation, instruct
the end user to walk through the outer edge of the
coverage pattern daily. This assures an alarm output
prior to arming.
12.0 Coverage Patterns
This product is factory assembled with the look down
zones (O, P, and Q) masked out. If you want to use these
zones, remove the masking tape from the lens (see Figure
15 and Figure 16).
Figures 17 and 18 show the optional barrier and long
range coverages.
