Safe, Unattended Operation of Powered Barrier Gates

Non-contact safety sensing for gates and automated closures to protect people and vehicles. SmartGate is designed for easy installation into existing facilities and can be configured to trigger an alarm event. The SmartGate system provides non-contact safety sensing for parking barrier gates and slide gates. Unlike older technologies, the SmartGate safety system has no narrowly focused light beams to keep aligned, no output lenses or sending units to keep clean, no bulbs or emitters to burn out, and no expensive in-ground installation. It does not need frequent adjustments or cleanings and functions with buildups of ice, water, snow and dust. The SmartGate system's invisible field puts safety sensing where it should be - moving with and preceding the hazardous closing gate arm. Patented technology provides the maximum area of safety sensing and the capability to sense both people and vehicles. Manufacturers, dealers, consultants, and end users have recognized SmartGate as the premier safety solution that helps to reduce the number of personal injury and vehicle damage claims and to cut overall liability exposure. The SmartGate non-contact safety system can easily be installed into any existing or new gate in about one hour. When alarmed, the SmartGate system sends signals that, when connected to the correct input on the gate operator, can signal to stop or reverse the motion of the closing gate arm. An invisible field surrounds the complete length of the gate arm. The larger the conductive object, the farther away the system will "see" it! The SmartGate safety system generates a weak RF energy field from a "Sense" antenna that is mounted along the length of the gate arm. Any conductive object introduced between the system's invisible field and the ground causes a change that is detected via the antenna causing SmartGate to provide an alarm signal to the gate controller.
