Step 5 Install Entrapment Protection - LiftMaster Elite Serie Manuel D'installation

To prevent SERIOUS INJURY or DEATH from a moving gate/door:
Entrapment protection devices MUST be installed to protect anyone
l
who may come near a moving gate/door.
Locate entrapment protection devices to protect in BOTH the open and
l
close gate/door cycles.

Step 5 Install Entrapment Protection

Entrapment protection MUST be installed according to the following UL
325 requirements:
Vertical gate/door operators require the installation of the first
l
external monitored entrapment protection device in the close
direction to function.
Every installation is unique. It is the responsibility of the installer to
l
ensure that ALL entrapment zones are protected with an external
monitored entrapment protection device, protecting both the open
and close gate/door cycles.
LiftMaster monitored external entrapment protection devices MUST
l
be used with LiftMaster operators to meet UL325 requirements,
see Accessories.
Test ALL entrapment protection devices after completing installation
l
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.
VERTICAL LIFT GATE ENTRAPMENT ZONE: Locations between a moving
gate or exposed operator components and a counter opposing edge or
surface where entrapment is possible up to 2.4 m (8 ft) above grade. Such
locations occur when the gap between a moving gate and fixed counter
opposing edges or surfaces, other than the ground or floor at the bottom of
the gate, is greater than 101.6 mm (4 in) and less than 406 mm (16 in) or
when the gap between a moving gate and fixed counter opposing edges or
surfaces at the bottom of the gate is less than 406 mm (16 in).
OVERHEAD PIVOT GATE ENTRAPMENT ZONE: Locations between a
moving gate or exposed operator components and a counter opposing
edge or surface where entrapment is possible up to 2.4 m (8 ft) above
grade. Such locations occur when the gap, measured in the horizontal
plane parallel to the roadway (such as a gate support post) and the gate
frame when the gate is in either the fully open position or fully closed
position, is greater than 57 mm (2-1/4 in ) and less than 406 mm (16 in)
or when the gap between a moving gate and fixed counter opposing edges
or surfaces at the bottom of the gate is less than 406 mm (16 in).
