REQUIRED to be installed in all areas accessible to potential entrapment and pinch
points.
• For a horizontal swing gate operator, at least one Monitored External Entrapment Sensor is
required in each direction of travel. Except, if there is no entrapment zone in one direction
of travel, it is not required to have a Monitored Entrapment sensor for that direction of
travel.
! If there is a possible entrapment zone in the open direction, an external sensor MUST be
connected to the “UL” input or the installation will not comply with UL 325.
! An external sensor connected to the “ReOpen” input terminal will protect against
entrapment ONLY in the closing direction.
• The installed sensor MUST be “10K Resistor Based”.
• You may connect up to FOUR monitored sensors, wired in parallel, to either the “UL” and/or
“ReOpen” terminals, for a total of 8 monitored sensors.
• Failure to install the required monitored entrapment protection sensor(s) may render the
gate operator INOPERABLE. The gate can be moved manually. Refer to page 11.
• Consult the installation manual of the sensor for detailed information about the usage,
installation and maintenance.
• Use only UL Recognized Component Edge Sensors and Photoelectric Sensors. Refer to pg 7.
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
