INSTALLATION To prevent SERIOUS INJURY or DEATH from a moving gate: l ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. l Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate. l Locate entrapment protection devices to protect in BOTH the open and close gate cycles. l Locate entrapment protection devices to protect between moving gate and RIGID objects, such as posts, walls, pillars, columns, or operator itself. Step 6 Install Entrapment Protection Entrapment protection MUST be installed according to the following UL 325 requirements: l Swing gate operators require the installation of the first external monitored entrapment protection device to function. l Every installation is unique. It is the responsibility of the installer to ensure that ALL entrapment zones are protected with an external monitored entrapment protection device, protecting both the open and close gate cycles. l LiftMaster monitored external entrapment protection devices MUST be used with LiftMaster operators to meet UL325 requirements, see Accessories. l Test ALL entrapment protection devices after completing installation of the operator. For testing instructions, refer to the manual provided with your entrapment protection device. Definitions ENTRAPMENT: The condition when a person is caught or held in a position that increases the risk of injury. SWING GATE ENTRAPMENT ZONE: Locations between a moving gate or moving, exposed operator components and a counter opposing edge or surface where entrapment is possible up to 1.8 m (6 ft) above grade. Such locations occur if during any point in travel: a. The gap between the bottom of a moving gate and the ground is greater than 101.6 mm (4 in) and less than 406 mm (16 in); or b. The distance between the center line of the pivot and the end of the wall, pillar, or column to which it is mounted when in the open or closed position exceeds 101.6 mm (4 in). Any other gap between a moving gate and fixed counter opposing edges or surfaces or other fixed objects is less than 406 mm (16 in) (examples are walls, curbs, berms or other immovable objects).

To prevent SERIOUS INJURY or DEATH from a moving gate:
l
ALL gate operator systems REQUIRE two independent entrapment
protection systems for each entrapment zone.
l
Entrapment protection devices MUST be installed to protect anyone
who may come near a moving gate.
l
Locate entrapment protection devices to protect in BOTH the open and
close gate cycles.
l
Locate entrapment protection devices to protect between moving gate
and RIGID objects, such as posts, walls, pillars, columns, or operator
itself.
Step 6 Install Entrapment Protection
Entrapment protection MUST be installed according to the following UL
325 requirements:
l
Swing gate operators require the installation of the first external
monitored entrapment protection device to function.
l
Every installation is unique. It is the responsibility of the installer to
ensure that ALL entrapment zones are protected with an external
monitored entrapment protection device, protecting both the open
and close gate cycles.
l
LiftMaster monitored external entrapment protection devices MUST
be used with LiftMaster operators to meet UL325 requirements,
see
Accessories
.
l
Test ALL entrapment protection devices after completing installation
of the operator. For testing instructions, refer to the manual provided
with your entrapment protection device.

locations occur if during any point in travel:
a.
The gap between the bottom of a moving gate and the ground is
greater than 101.6 mm (4 in) and less than 406 mm (16 in); or
b.
The distance between the center line of the pivot and the end of the
