Protect your home, business or industrial site with the Gallagher F31 Energiser, a high-performance security fence controller from the F-Series, built for the Gallagher monitored pulse fence system. It is a single platform that scales from simple, single-zone fence protection to fully networked, multi-controller perimeter security.
The F31 is the single-circuit model in the range. It delivers a strong, consistent pulse to deter intruders, and it constantly monitors the fence, reporting faults and attacks so you can respond quickly.
Key Features
- Powerful dual-pulse output: About 2.3J output per circuit with high-voltage dual pulse of up to 16kV for strong deterrence.
- Single-circuit design: One independent fence zone, ideal for compact and medium perimeters.
- Standalone or networked: Connect to your existing alarm panel using simple I/O connections, or integrate into a fully networked (HBUS) Gallagher security system.
- Smart alarm monitoring: Alarms for fence zone faults, missing battery, battery test failure, tamper, over-temperature, signal loss, conflicting sync masters and service mode.
- Clear on-unit display: Fence health and alarm status are visible right at the controller cover.
- Five-day alarm history: Historic alarm retention helps with troubleshooting and incident review.
- Voltage and temperature reporting: Internal temperature monitoring protects the unit and helps you spot problems early.
- Wide power input: Works on 90 to 265V AC, 50/60Hz, suitable for varied mains conditions.
- Easy maintenance: Service mode and a maintenance-friendly design keep upkeep simple.
- Pulse synchronization: Synchronize with other nearby electric fences to prevent interference.
- Backup power support: Support for external power management options so your fence stays live during outages.
Ideal Applications
- Residential homes, estates and gated communities
- Commercial premises, offices and warehouses
- Factories, industrial yards and depots
- Schools, hospitals and institutions
- Farms, lodges, fuel stations and perimeter walls
- Sites needing integration with an alarm panel or security management system
