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.

Entrapment protection sensor types:
Type A - Inherent entrapment sensing systems.

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.
