ENTRAPMENT PROTECTION
This vehicular gate operator is equipped with an inherent adjustable current sensing system (Type A).
This system will sense an obstruction in both the opening and closing gate cycles, and will cause the
gate to reverse direction should an obstruction be encountered. If the system detects a second
obstruction before reaching the full open or close limit after the initial reversal, an alarm will activate
and the operator will require a reset before resuming normal operation. See Section 2 for more
information.
EXTERNAL ENTRAPMENT PROTECTION
Non-contact sensors must be installed to provide external entrapment protection. For gate operators
utilizing a non-contact sensor:
• See diagram below for placement of non-contact sensors.
• Care should be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips
the sensor while the gate is still moving, and
• One or more non-contact sensors shall be located where the risk of entrapment or
obstruction exists, such as the perimeter reachable by a moving gate or barrier.
Pedestrian Access
The gate must be installed in a location so that
enough clearance is supplied between the gate and
adjacent structures when opening and closing to
reduce the risk of entrapment. Swinging gates shall
not open into public access areas.
