EXTERNAL ENTRAPMENT PROTECTION:
Non-contact and contact sensors must be installed individually or in combination with
each other to provide external entrapment protection.
Care should be exercised to reduce the risk of nuisance tripping, such as when a vehi-
cle 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 perim-
eter reachable by a moving gate or barrier.
A hardwired contact sensor shall be located and its wiring arranged so that the com-
munication between the sensor and the gate operator is not subjected to mechanical
damage.
A wireless contact sensor such as one that transmits radio frequency (RF) signals to
the gate operator for entrapment protection functions shall be located where the trans-
mission of the signals are not obstructed or impeded by building structures, natural
landscaping or similar obstruction.
DURING INSTALLATION
DISCONNECT POWER at the control panel before making any electric service pow-
er connection.
Be aware of all moving parts and avoid close proximity to any pinch points.
Know how to operate the manual release.
Adjust the unit to use the minimum force required to operate the gate smoothly even
during mid-travel reversing.
Place controls a minimum of 8 feet away from the gate so that the user can see the
gate and operate controls but cannot touch the gate or gate operator while operating
the controls.
Warning signs must be placed on each side of the gate or in high-visibility areas to
alert of automatic gate operations.
