Installation and Operations Manual — LXL Gate Operator
• at the leading edge, the trailing edge, and also post-mounted both inside and outside of, a
vehicular horizontal slide gate;
• at the bottom edge of a vehicular vertical slide gate; and
• at the entrapment point of a vehicular vertical pivot gate.
A wired contact sensor shall be located, and its wiring arranged, so that communication between
sensor and gate operator is not subjected to mechanical damage. A wireless contact sensor shall
be located where the transmission of the signals is not obstructed or impeded by building
structures, natural landscaping, or similar obstructions, and shall function under the intended end
use conditions.
For operators utilizing continuous pressure activating device (type D), controls must be placed so
that the user has full view of the gate area when the gate is moving. A placard must be placed
adjacent to the controls and no other activation devices shall be connected. Most importantly, an
automatic closing device shall not be employed.
2.3 Statements in Manufacturer's Instructions Concerning
Installation
Gate and fence dealers can expect to see in gate operator instructions the following statements:
1. The operator must be appropriate for the construction of the gate and the usage class of
the gate. The appropriate primary and secondary safety devices to be used are a major
consideration to support this requirement.
2. All openings of a horizontal slide gate, and the portion of the fence where the slide gate
passes, must be guarded or screened. These specific requirements in UL-325 that govern
this provision were developed to address "reach-through" occurrences. For example, slide
gates must have a protective cover 48 inches in height extending from the bottom of the
gate/fence panel.
3. All exposed entrapment points must be eliminated or guarded. It is up to the individual
gate and fence dealers to identify these points on a product-by-product basis, or on a job-
by-job basis.
4. Guarding must be supplied for exposed rollers. Exposed rollers are regarded as potential
pinch points.
2.4 Gate And Fence Dealer Documentation Suggestions
In dealing with the effects of the new provisions, here are some suggestions gate and fence
dealers may consider to expand their documentation of gate projects. One possibility is to
visually document, either via photography or videotape, the complete gate installation including
applicable signs and labels, and the owner receiving the instruction manual from the installer.
Other options could include the development and use of an installation checklist, a consumer
sign-off form, and a service/preventative maintenance contract.
