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 photo-eyes,
•
Type B2
- Contact sensors such as gate edges or
•
Type D
- Constant pressure control.
•
Type E
- Built-in audio alarm.
