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.
• 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.
