SECONDARY ENTRAPMENT DEVICES
USAutomatic designs all control boards with secondary entrapment inputs. USAutomatic
recommends that UL325 listed secondary safety devices be installed with all installations.
USAutomaticrecommendsthatthesedevicesbeconnectedafterpropergateinstallationand

SAFETY INSTALLATION INFORMATION
4
WARNING
TO REDUCE THE RISK OF INJURY OR DEATH
1. READ AND FOLLOW ALL INSTRUCTIONS
2. Study the entire Safety Section paying particularly close attention to the entrapment zones
and be aware of these areas not only during use but also during any adjustments to the unit.
3. Do not attempt to enter the gate area while the gate is moving. Wait until the gate comes to
a complete stop.
4. Never let children operate or play with gate controls or any other activation device. Keep
remote control away from children.
5. DO NOT ALLOW CHILDREN TO PLAY IN THE AREA OF THE GATE.
6. Do not allow anyone to ride on the gate.
7. Always keep people and objects away from the gate.
8. NO ONE SHOULD CROSS THE PATH OF A MOVING GATE.
9. Operate the gate only when it is fully visible, free of persons or obstructions, and properly
adjusted.
10. Do not attempt to “beat the gate” while the gate is opening or closing. This is extremely
dangerous.
11. Test gate operator monthly. The gate must stop and reverse directions upon contacting a rigid
object or when the secondary entrapment device is activated.
12. After all adjustments have been made to the sensitivity (current sense) circuit, secondary
entrapment devices and all other external devices installed, the safety devices must be
checked again. Failure to adjust and retest the gate operator can increase the risk of injury
or death.
13. Verify that the emergency release (manual release) pin can be easily removed.
14. KEEP GATES PROPERLY MAINTAINED. Tighten all bolts and grease hinges and pivot points.
15. THE ENTRANCE IS TO BE USED BY VEHICLES ONLY. Pedestrians must use a separate
entrance.
16. All safety features required by UL 325 are incorporated in the capabilities of all USAutomatic
Control boards and should be utilized, including but not limited to, safety edges, photo
electric eyes, reverse sensing.
17. Test the current sense feature and all safety devices regularly to insure correct operation.
18. The USAutomatic battery charger is designed to operate with a recommended +12 VDC,
sealed maintenance free type Group U-1 battery. 30 amp hour minimum.
19. All control stations should be located at least 6 feet from any moving part of the gate
or operator.
20. Do not ever install any control device where a user will be tempted to reach through the gate
or fence to activate a gate.
21. Do not attempt to completely seal the control box. Battery needs some air ow.
22. SAVE THESE INSTRUCTIONS!!
