WIND LOAD FACTORS & SITE PREP
Wind Load Factors & Site Prep
Wind load is always a factor when considering the appropriate gate for a particular site. Solid gate panels
produce a larger wind load than gates with slats or open decorative features. If you are installing a gate
system in high wind areas, the gate design will affect the load on the gate system. Because wind force acts
the same as an obstruction, it is important that gates be designed to present a relatively low surface area
for the wind to push on the gate panel.
If the gate is heavy and near the weight capacity of what the gate system can handle (see specifications for
FoldSmart on the back cover), make sure it has an open design that allows wind to flow through it. A solid
or semi-solid gate design under certain wind load conditions may cause damage to the gate system and is
not covered by the Wallace Perimeter Security Limited Warranty.
Several factors play into the calculations of the wind load on a gate panel. To find out the maximum wind
speed in areas around the United States/Canada or other regions, search for the relevant government
wind speed maps on the internet . If you don’t know how to calculate for wind load, ask a mechanical
engineer or site architect for assistance prior to installing the gate system and gate panels.
FoldSmart incorporates a Type-A inherent entrapment sensor (IES) into its design per UL 325 Safety
Standards. (More information about adjusting the adaptive IES software can be found in this manual
under “Adjusting the IES Sensitivity” on page 70 .) When the IES trips, it sends a signal to the gate
system to stop and reverse direction. This feature may be falsely triggered in excessively windy conditions
because the wind itself, acting over the surface area of the gate panel, can provide the necessary force to
trigger the IES.
Do not adjust IES sensitivity to
accommodate for inappropriately
designed gate panels. Loss of IES
sensitivity increases mechanical wear
on the gate hardware and the gate
system. It may also pose a safety
hazard. Compensating for wind loads
by adjusting the IES may set the IES
sensitivity to a level which, when
encountering an obstruction, ignores
the obstruction and fails to reverse
direction. For more information, refer
to “Adjusting the IES Sensitivity” on
page 70 .
