NOTE: The same type of device shall not be utilized for both the primary and secondary entrapment protection means. Use
of a single device to cover both the openings and closing directions is in accordance with this 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 types:
Type A -
Inherent entrapment sensing system. See 31.1.5
TypeB1 -
Provision for connection of, or supplied with, a non-contact sensor (photoelectric sensor or the equivalent). See
31.1.6-31.1.9.
Type B2 -
Provision for connection of, or supplied with, a contact sensor (edge device or equivalent). See 31.1.7 and
31.1.10 - 31.1.12.
Type C -
Inherent adjustable clutch or pressure relief device. See 31.1.13.
Type D -
Provision for connection of, or supplied with, an actuating device requiring continuous pressure to maintain
opening or closing motion of the gate. See 31.1.14 and 31.1.15.
Type E -
An inherent audio alarm. See 31.1.16, 31.1.17 and 31.1.18.

1.4 Gate Operator Classifications
Four distinct types of classifications have been established:
• Class I: Residential usage, covering one to four single-family dwellings.
• Class II: Commercial usage where general public access is expected; a common
application would be a public parking lot or gated community.
• Class III: Industrial usage where limited access is expected; one example is a ware- house
property entrance not intended to serve the general public.
• Class IV: Restricted access; this includes applications such as a prison entrance that is
monitored either in person or via closed circuit television.
Gate speed shall be no greater than 1 foot per second in Class I and II applications.
