U.S. Automatic Sentry 300 Series Single Swing Gate Opener

U.S Automatic Sentry 300 Series Single Gate Opener is a simple Plug N GO installation with a self-explanatory control board that makes the system DIY friendly. The installation time is usually under one hour. This unit requires a 12-Volt dc battery (not included) that is charged by an AC (120 VAC) supplied transformer. The transformer is recommended to be within 1000' of the gate area. An additional extension cable is required if the AC power is more than 10' from the gate opener control box.

The Sentry 300 Series Gate Opener allows the option of using solar power (sold separately). Normally only one solar panel is necessary, and it will be capable of a high number of cycles per day. Any of the accessories added to this unit must be solar-friendly. To determine how many cycles to expect per day from your solar system you can review our solar region map.

Some of the characteristics of the U.S Sentry 300 control board are high-quality components and industry-leading ideas like auto-resetting fuses for motor protection avoiding unnecessary expenses on replacement of fuses. This control board also has built-in potentiometers to adjust the stop limits.

U.S Automatic Sentry 300 gate openers require welding for installation. This will secure the linear actuator mount to the gate hinge post. If the bolt-on bracket is used, additional maintenance will be needed to keep the brackets secure. To provide the correct support, and to fasten the linear actuator mount, we recommend installing the brackets using carriage bolts, lock nuts, and washers (Do Not Use Lag Type Bolts). Loose or unsecured installation of linear actuator mount will cause the unit to fail and not properly operate.

The type of gate, power supply, and contributing environmental factors determines whether or not additional supplies are needed. For further details, consult the product manual that comes with this gate opener model.
