IMPORTANT SAFETY INSTRUCTIONS
Secondary Means of Protection Against Entrapment
As specified by Gate Operator Safety Standard, UL 325 (30A.1.1), automatic gate operators shall have an inherent
entrapment sensing system, and shall have
provisions for, or be supplied with,
at least one independent secondary
means to protect against entrapment. The 2000XLS utilizes
Type A,
an inherent (i.e., built-in) entrapment sensing system
as the
primary
type of entrapment protection. Also, the 2000XLS has
provisions for
the connection of
Type B1 or B2
protection to be used as the
secondary
type of entrapment protection, if desired.
1. For gate operators utilizing a non-contact sensor (e.g., photo-electric sensor– Type B1) in accordance with UL 325
(51.8.4 [h]):
A. Refer to the sensor manufacturer’s instructions on the placement of non-contact sensors for each type of
application.
B. Care shall be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the
gate is still moving.
C. One or more non-contact sensors shall be located where the risk of entrapment or obstruction exists, such as the
perimeter reachable by a moving gate or barrier.
2.
For gate operators utilizing a contact sensor (e.g., safety edge sensor– Type B2) in accordance with UL 325 (51.8.4 [i]):
A. One or more contact sensors shall be located at the leading edge, bottom edge, and post edge, both inside and
outside of a vehicular swing gate system.
B. A hard wired contact sensor shall be located and its wiring arranged so that the communication between the
sensor and the gate operator is not subjected to mechanical damage.
C. 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 transmission of the signals are not obstructed or
impeded by building structures, natural landscaping or similar obstruction. A wireless contact sensor shall
function under the intended end-use conditions.
You may want to consider adding photo beams to your installation. GTO Photo Beams
[R4222]
provide a “non
contact” means of entrapment protection.
ENTRAPMENT ALARM (UL 325; 30A.1.1A)
The 2000XLS Gate Operator is designed to stop and reverse within 2 seconds when the gate comes in contact with
an obstruction. Additionally, these operators are equipped with an
audio entrapment alarm
which will activate if the
unit obstructs
twice
while opening or closing. This alarm will sound for a period of 5 minutes, or until the operator
receives an intended signal from a hard wired entry/exit source (e.g. push button control or keypad) and the gate
returns to a fully open or fully closed position. Turning the power switch on the control box OFF and back ON will also
deactivate the alarm. Wireless controls such as transmitters and wireless keypads will not deactivate the alarm.
