Gallagher North America G51100 Live Fence Indicator

Product Description

The GALLAGHER NORTH AMERICA G51100 is a live fence indicator designed to provide at-a-glance voltage status on electric fence systems. The device flashes to confirm that a fence is energized, giving installers and operators a clear visual signal without requiring direct contact with the fence wire. A built-in low-voltage cutoff prevents false readings — the indicator will not flash when fence voltage drops below a functional threshold. The G51100 is built for outdoor use, with water-resistant and UV-resistant construction suited to continuous field exposure. It is used by agricultural fencing contractors, livestock managers, and utility maintenance crews.

The G51100 is suited for electric fence perimeters on farms, ranches, and managed grazing operations. The device mounts quickly by inserting the earth stake into the ground and clipping directly onto fence wire or tape. Its flash signal is visible from up to 3000 feet at night, making it practical for monitoring long fence runs or remote paddock boundaries. No tools are required for installation, and no wiring is involved. It functions as a passive monitoring device that stays mounted on the fence line for continuous status indication.

Key Features

• Visible flash signal readable from up to 3000 feet at night for remote monitoring
• Low-voltage cutoff prevents false-positive indication when fence is under-energized
• Clip-on installation attaches directly to fence wire or tape — no tools required
• Earth stake included for ground contact without additional hardware
• Water-resistant and UV-resistant housing rated for permanent outdoor installation

Compatibility

Designed as a general-purpose fence status indicator for electric fence systems using wire or tape conductors. Compatible with standard clip-on fence wire and tape configurations typical in agricultural and perimeter fencing applications.

Installation Notes

Installation is performed by placing the earth stake firmly into the ground near the fence line and clipping the indicator directly onto the live fence wire or tape. Verify that the fence energizer is powered off before handling fence components during setup. Once installed, restore power to the energizer and confirm the indicator flashes to validate proper fence voltage. No licensed trade is required for installation, but all electric fence systems should comply with applicable local agricultural and electrical codes.
