       Dynmaic FAQ
    What are the advantages of DC over AC?
    With a DC opener you don’t need an electrician to install it, is it safer because it is low voltage, and power is more readily available through everyday outlets.
    What is the range of use for the automatic driveway gate opening transmitters?

    The range of use for the automatic driveway gate opener transmitters would vary for each automatic driveway gate opener installation; varying on model installed and external factors. 

    The Estate Swing automatic driveway gate openers generally have a range of approximately 300 feet for the automatic driveway gate opener transmitters that comes with each system. .

    The published range for GTO and Lift Master radio controls is 50-100 feet, and must be used in line-of-sight of the gate for safety purposes.

    The Apollo automatic driveway gate openers generally have a range of approximately 300 feet for the automatic driveway gate opener transmitters that comes with each system (when bought from GateCrafters.com).

    How should I run my wire to my automatic gate lock?
    It runs from your control panel. What we suggest is running it along a vertical bar on the gate. You can use zip ties to hold it to the back, matching the color of the zip ties to that of your gate.
    Which automatic driveway gate opener to use with a wood gate?

    Privacy fences usually don't work well with swing automatic driveway gate openers because the solid surface acts as a "sail" in the wind. 

    This adds strain to the motor of the automatic driveway gate opener and generally trips safety sensors that are a part of all automatic driveway gate opener systems. Either you can use an automatic slide driveway gate opener or you would have to manually operate a swing driveway gate opener in windy conditions. It would also be recommended to use an automatic driveway gate lock to lock your driveway gate shut in the closed position. This takes pressure off of the automatic driveway gate opener’s arm when the wind pushes against the driveway gate.

    The easiest automatic driveway gate opener to manually operate would be the Estate Swing E-S 1600/1602 automatic driveway gate opener. The Estate Swing E-S 1600/1602 automatic driveway gate opener has a key release on the top that releases the gears and allows the driveway gate to be moved manually without having to remove the automatic driveway gate opener.
