NOTE: The same type of device shall not be utilized for both the primary and the secondary entrapment protection
means. Using 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 a Type B1 for one direction and a 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.
The Usage Classes are:
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
