The Estate Swing automatic free exit vehicle detecting exit wand makes leaving your property a breeze. Any car driving towards the gate will be detected and the gate will automatically open. Installation for the wand is quite simple. The wand gets buried directly into the ground next to the driveway, not under it, so there is no saw cutting or paving to do. As metal moves past the sensor the gate opener is triggered to open. The exit wand comes in two models: standard and deluxe. The standard model is a simple time tested design great for residential applications. The standard comes with 50 feet of lead wire for a 4 wire connection to any gate opener control board. The deluxe model comes with 100 feet of lead wire for additional distances from the driveway gate. The added distance allows for a faster exiting of the property. In addition to the longer wire the deluxe model comes with a grounding strap attached to the exit sensor. The grounding strap allows the user to drive a grounding rod next to the wand which allows the dissipation of electrical noise that can cause false openings. With both models it is highly recommended to position the exit wand as far back from the gate as your property allows. This will give more time for the gate to open and less of a chance for the car exiting to move into the path of the gate. Cars need to be moving to trigger the wand, so further back the cars will not be slowing or stopping yet to wait for the gate. Note: Exit wands / sensors should not be used on properties in which the driveway gate is designed to keep in pets, children or live stock due to possibility for unintentional openings. Our suggestion is to use a keypad for exiting so the gate will only open when it is intended to by the code inputted into the keypad.
