1-6 ILS Open Plus 3.0 Installation Manual
Site Survey
A site survey document should already have been completed for the intended installation.
Refer to the site survey document for details regarding physical installation, proper
grounding, proper electrical connections, etc.
Aisle Width
The spacing of the gates depends upon the gate configuration, but the maximum aisle
width distance (centerline to centerline) is 91 cm (36”), and minimum of 81.5 cm (32”).
Widths narrower than 81.5 cm (32”) does not meet ADA guidelines. The gate base should
be installed first as it provides the template necessary for securing the gate to the floor. See
“Determining the Mounting Holes” on page 1-10 to begin.
Gate Area Requirements
For maximum performance, the gates should have a clearance of at least 50 cm (19.7”)
between the antenna and objects that impact RF performance (such as metal). Otherwise,
the Reader range will be significantly reduced. At a minimum, the gates must have at least
a clearance of 20 cm (7.9”) clearance on all sides.
Orientation
The orientation of the gates should be determined and then maintained consistently
between multiple gate antennas across the adjacent aisles. This results in the electronics
bays all facing the same direction.
Multiple Gate Scenario
If multiple sets (one primary and up to 2 secondary) of gates are used, a minimum
separation of 8 m (26.2 ft) must be kept between the antennas or gates. For shorter
distances (1 m - 8 m [9.8 ft - 26.2 ft]) the Readers must be synchronized; otherwise the
Reader range will be significantly reduced.
