  GTO 4000XLS Instruction Manual © 01.10.12  

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 4000XLS utilizes 

Type A, an inherent (i.e., built-in) entrapment sensing system 

as the 

primary type of entrapment protection. Also, the 4000XLS 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.

provide a “non contact” 

means of entrapment protection.  

The 4000XLS 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.
