:
This vehicular gate operator is equipped with an inherent (Type A) entrapment sensing device. The system will sense an
obstruction in both the open and close cycles, and will reverse the direction of the gate travel upon encountering an
obstruction. If the system detects a second obstruction before reaching the full open or close limit after the initial reversal, a
warning alarm will activate and the operator will require a reset before resuming normal operation. This is called a “Hard
Shutdown”. Please read and follow the “Shutdown Conditions” section of this manual for more directions.

REVENTION
:
Non-contact and/or contact sensors must be installed to provide external entrapment prevention in accordance with UL325
section 3.1. Use only UL325 compliant devices and low voltage (24V) devices. Carefully follow the installation manual for the
UL325 device used for installation, usage, and maintenance.
Non-Contact Sensors (Photo Beams):
Non-contact sensors generally are photoelectric cells or like devices. For gate operators utilizing non-contact sensors:
1. Refer to the diagram below for placement of non-contact sensors.
2. Use care to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still moving.
3. One or more non-contact sensors shall be located where a risk of entrapment or obstruction exists, such as the
perimeter reachable by a moving gate or barrier. Use caution when installing non-contact sensors since some
devices only cover a select area. For example, a photo beam will not cover the full height of a gate/fence area.
Refer to the diagram below.

Fence
Protect against all entrapments
areas that exist:
1. Between the gate and the adjacent
fence when the gate is in the open
cycle
2. The gate operator and the slide gate
when the gate is in the open and
close cycles
3. At the front end of the gate when the
gate is in the close cycle.
Open beams help protect
areas between the gate and
the adjacent fence. CAUTION:
This beam should be used in
conjunction with a contact
sensor.
Close beams help
prevent the gate from
hitting obstructions
during the close cycle.
