For this board to function, a UL 325 photo-eye safety device must be attached to the board and used in the operating system. This USAutomatic Gate Operator is NOT compatible with the EMX IRB-RET Photo Eyes.
USAutomatic Sentry 300 Series Single Swing Gate Opener
The Plug N Go design of all installed components and the easy-to-understand Sentry control board make this the simplest gate opener for the do-it-yourself installer. Typical installation time is under one hour.
The Sentry 300 automatic gate opener is powered by a 12-volt DC battery (not included). This battery is charged by the supplied transformer, which requires AC power (120 VAC) to be located either at the gate area or within 1,000 feet of it. If the AC power is more than 10 feet from the gate opener's control box, additional extension cable is required.
The automatic gate opener's solar charging method is optional and requires the Sentry solar panel kit (sold separately) for proper operation. Typically, only one panel will be required. The Sentry single swing gate opener is capable of a high number of cycles per day. For information on what you can expect from a solar-charged system, see the solar charging section of this site. Any accessories added to your gate opener must be solar-friendly and will be identified as such. Review the solar region map to determine the number of cycles per day you can expect from a solar-charged system.
The Sentry 300 control board features high-quality components and industry-leading innovations, such as auto-resetting fuses for motor protection. The outdated auto-type fuse that blows and must be replaced has been eliminated from this controller to avoid the unnecessary expense of purchasing fuses. Another patent-pending feature of the control board is the onboard potentiometers for adjusting stop limits.
The Sentry 300 Series Swing Gate Opener by USAutomatic is proudly manufactured in the US.
