This is a weather-resistant companion device that works with USAutomatic Sentry 300 gate openers equipped with the latest UL 325 obstruction sensing devices. The Nexx Gate App allows up to eleven users to securely open, close, and monitor their gate from anywhere in the world. The NEW Sentry "Blue" circuit board (500022) with the DB9 Port is required for full functionality from the mobile App. If installed on older units you will NOT have gate position status. A monitored safety device (550013) is, not only highly recommended, but also required for this board to function.
DISCLAIMER: IF SOLAR CHARGED SYSTEM THE CHARGING DEVICE MAY NEED TO BE UPGRADED TO ACCOMMODATE A 20 WATT SOLAR PANEL. SEE DESCRIPTION BELOW FOR DETAILS.
If you have a 6w solar panel (standard with older models) you will need to add an additional 10w solar (520026) panel or remove the 6w solar panel and replace it with our 20w solar panel (520030). If you have the discontinued charger (520007) you will also need to replace that with our 520001 charger. Failure to upgrade this will result in battery charging issues.
