Can the USAutomatic Patriot Gate Opener Operate Without the J2 Accessory Plug Connected?
The USAutomatic Patriot and Ranger gate openers are engineered to meet UL325 safety standards, which are designed to protect people and property from potential injury or damage caused by automated gates. One of the key features that enables this compliance is the J2 accessory plug on the control board.
The J2 plug acts as a connection point for monitored entrapment protection devices, such as photo eyes (infrared beam sensors) and safety edges (pressure-sensitive strips). These devices allow the gate system to detect obstacles in its path and stop or reverse movement to prevent accidents. Without these safety measures, the operator is not allowed to run under normal circumstances, it's a built-in safeguard.
However, during installation, testing, or troubleshooting, it's common for installers to work on the system before safety devices are wired in. This raises the question:
Can the gate still operate without anything connected to the J2 terminal?
The Short Answer: Yes, but only temporarily, and with safety risks.
Paraphrased from the official USAutomatic control board manuals, you can temporarily override the J2 safety requirement using the S4 push button. This function is specifically designed for use during setup, troubleshooting, or diagnostics, not for long-term or daily operation.
"If no monitored safety devices are connected, the gate operator will not run unless the S4 push button is pressed and held."
In practical terms, this means that when no photo eyes or safety edges are connected to the J2 terminal block, the control board recognizes that the system is unprotected and will automatically prevent gate movement. To bypass this and allow the gate to function temporarily, the installer or technician must manually press and hold the S4 button on the control board during operation.
This is a built-in safety feature that ensures the gate doesn't operate unintentionally without proper safeguards in place. It's intentionally designed as a momentary override, once the button is released or the cycle ends, the override is cleared, and the system will again require safety devices to function normally.
This override is only for short-term use during installation or maintenance. It should never be used as a permanent solution, as doing so disables key safety features intended to prevent injury or damage.
How the S4/S5 Override Works
- S4 (S5) is a physical push button located on the control board.
- To temporarily bypass J2, you must press and hold the S4 (S5) button while operating the gate.
- The override is not permanent, once released, the board will again require a safety device for operation.
- This method is strictly for setup, diagnostics, or temporary troubleshooting.
Note for older/discontinued models: The override button may be labeled S5 instead of S4. The function is similar, but always consult your specific model's manual for correct usage.
Safety Warning
Using the S4 override disables all monitored entrapment protection, meaning the gate will not detect obstacles. This poses a serious risk of injury or property damage. Never use S4 as a permanent workaround. It is intended only for temporary use during installation or testing by qualified personnel.

Review: Can the USAutomatic Patriot Gate Opener Operate Without the J2 Accessory Plug Connected?
Yes, USAutomatic gate openers can temporarily operate without safety devices connected to the J2 plug, but only when you press and hold the S4 (or S5) button. This override is meant only for testing and setup, and should never be used during normal operation.
For safe and compliant operation, always install the required monitored entrapment protection devices before putting the system into regular use.
