5. The End of Type E.
Type E (audible alarm) devices can no longer be used for entrapment protection. This change
was made because the Type E device is really a warning device, not an entrapment-protection device. Also, all gate
operator classes are now required to have an audio alarm that sounds when two successive obstructions are
encountered via a contact-type system.
6. Access Control Location for Emergency Use.
An exception has been added in the manufacturer’s instructional
requirements for the location of controls that operate the gate.
The instructional requirements state that these controls must be at least 6' away from any moving part of the gate. In the
new exception, “Emergency access controls only accessible by authorized personnel (e.g., fire, police, EMS) may be
placed at any location in the line-of-sight of the gate.”
7. Barrier-Arm Operator Exception.
An exception has changed for barrier-arm gate operators requiring entrapment
protection. The previous exception stated that a barrier-arm operator did not require entrapment protection if the arm
did not move toward a rigid object closer than 2'. The distance has been reduced to 16" so it more closely aligns with the
industry-defined entrapment protection provisions in ASTM F2200.
8. Gate Operator Class II and Class III Definitions.
The definitions for installation classes for gate operators were
modified. Class II now includes commercial locations
accessible
to the general public. Class III was refined to specify
industrial locations
not accessible
to the general public. These changes, while seemingly minor, may affect which gate
operator is suitable for a particular installation location.

VERITICAL BARRIER NOTE:
Barrier gate operators (arm) that is not intended to move toward a rigid objact closer than 16 inches (406mm)
are not required to be provided with a means of entrapment protection

TYPE C
Inherent entrapment protection system
Non-contact sensors such as photoelectric sensors or equivalents
Contact sensors such as edge sensors or equivalent devices
Inherent force limiting, inherent adjustable clutch or inherent pressure relief device
The same type of device shall not be used for both 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. Tice installer is required to install entrapment protection devices in each entrapment zone
TYPE D
Actuating device requiring constant pressure to maintain opening or closing motion of the gate
