Fence Alert | High-Visibility Voltage Warning Light

Instant visual peace of mind. Know your fence is hot without leaving the porch.

The Fence Alert Warning Light is a rugged, “set-and-forget” beacon that clips directly onto your electric fence. It remains dormant while your fence is operating at full power, but the moment your voltage drops below your chosen threshold, it triggers a high-intensity strobe.

Whether it’s a fallen branch, heavy weed growth, or an energizer failure, you’ll see the warning light and know there has been a drop in voltage.

Why Use a Fence Alert?

• High-Intensity Flash: Engineered for maximum visibility during the day and piercing brightness at night.

• No Grounding Required: Simply clip it onto any live wire, rope, or tape. It operates entirely off the pulse of the fence.

• Adjustable Sensitivity: Features dual-stage trigger levels to suit your specific containment needs:

  • 1.0 kV (Low): Ideal for basic containment or sheep/cattle.

  • 2.5 kV (High): Best for sensitive livestock or high-pressure areas.

• Universal Compatibility: Designed to work with all pulsed energizers and all wire types, including high-tensile steel, aluminum, and portable poly products.

• Long-Life Battery: Operates on a standard lithium button cell (included), providing up to 5 years of standby life or weeks of continuous flashing.

Simple 3-Step Setup

1. Set Your Threshold: Toggle the internal switch to your preferred voltage floor.

2. Clip & Go: Snap the heavy-duty, weather-resistant clip onto your fence line.

3. Visual Check: If the light is dark, your fence is hot. If it’s flashing, you have a fault that needs attention.

Technical Specifications

• Visibility: Up to 1.5 km (approx. 1 mile) in ideal conditions.

• Compatibility: All pulsed energizers (Steel wire, Poly-wire, Poly-rope, Poly-tape).

• Trigger Levels: User-selectable 1.0 kV or 2.5 kV.

• Casing: Impact-resistant, UV-stabilized, and 100% waterproof.

• Power Source: Replaceable CR2032 Lithium Button Cell (Included).

Strategic Placement Tip

Install the Fence Alert in a high-visibility location—such as near a main gate, along a driveway, or within sight of a farmhouse window. If you see a red flash during your morning routine, you’ll know exactly when to grab your Fault Finder to begin troubleshooting.
