This chart illustrates the entrapment protection requirements for the UL325 classes.
GATE OPERATOR ENTRAPMENT PROTECTION
UL325 Classification
CLASS I-CLASS IV
In order to complete a proper installation you must satisfy the entrapment
protection chart shown. That means that the installation must have one primary
means of entrapment protection and one independent secondary means of
entrapment protection. Both primary and secondary entrapment protection
methods must be designed, arranged or configured to protect against entrapments
in both the open and close directions of gate travel.
For Example: For a gate system that is installed on a single-family residence
(UL325 Class I) you must provide the following: As your primary type of
entrapment protection you must provide
• Type A - Inherent (built into the operator) entrapment sensing and at least
one of the following as your secondary entrapment protection:
• Type B1 - Non-contact sensors such as photoelectric sensors,
• Type B2 - Contact sensors such as gate edges
NOTE: UL requires that all installations must have warning signs placed in plain view
on both sides of the gate to warn pedestrians of the dangers of motorized gate
systems.
