Note—The same type of device shall not be utilized for both the primary and the secondary entrapment
protection means. Use of a single device to cover both the opening and closing directions is in accordance with
the requirement; however, a single device is not required to cover both directions. A combination of one Type
B1 for one direction and one Type B2 for the other direction is the equivalent of one device for the purpose of
complying with the requirements of either the primary or secondary entrapment protection means.
aEntrapment protection sensor types:
Type A - Inherent entrapment sensing systems.
Type B1 - A non-contact sensor (photoelectric sensor or the equivalent).
Type B2 - A contact sensor (edge sensor device or the equivalent).
Type C - Inherent adjustable clutch or pressure relief device.
Type D - An actuating device requiring continuous pressure to maintain opening or closing
motion of the gate.
Type E - An inherent audio alarm, which warns a minimum of 3 seconds before operation.
UL Usage Class Information:
The automatic vehicular operator must also be labeled as appropriate for both the type and usage class of the
gate. Installers must verify that the gate operator is labeled for the intended application. Note: Sliding gate
operators installed in Class I & II applications must not move the gate faster than 12 inches per second.
Class I:
Intended for use in a location with one to four single family dwellings, or a parking area associated
therewith.
Class II:
Intended for use in a commercial location or building such as a multi-family housing unit (five or more
single family units) hotel, garages, retail store or other building servicing the general public.
Class III:
Intended for use in an industrial location or building such as a factory or loading dock or other
locations not intended to service the general public.
Class IV:
Intended for use in a guarded industrial location or building such as an airport security area or other
restricted access locations not servicing the general public, in which access is monitored by security personnel
or via closed circuitry.
