### About this product

The HAMMER 680 ENERGISER is an electric fence energizer from Hammer. It powers an electric fence, sending pulses along the wires so that the fence deters intruders and can warn you of a fault or a break.

### What to check before you buy

Size it to the length of your fence and the number of wire lines, with some margin for growth. Good earthing is essential for a fence to work well. Trim back any vegetation touching the wires, because it weakens the fence and can cause false alarms. Secom World can supply and install it for you, so ask us to look at your site if you would like advice on the setup.
