A warning device that tells you in a flash your Power Fence is operating. Voltage indication from a distance. Visible from 1000metres (300ft) at night. With a fence voltage of approximately 3kV or more the Livelite will flash with every energizer pulse. If the fence voltage drops below 3kV it will flash intermittently or not at all in severe cases. Tight connections and a good earth are required for best flash intensity from any energizer. Easy installation – attach red lead to electrified fence wire, green lead to earth for PowerPlus mains and battery (M & B) series energizers. Older energizers may flash brighter with leads reversed. If incorrectly connected the Livelite will operate dimly.
