Ask any homeowner in Pakistan what their biggest concern about an electric fence is, and you will hear the same answer time and again: “What happens when the power goes out?”
Load shedding is a daily reality across Pakistan, from Lahore and Karachi to Islamabad. If your electric fence simply switches off every time the grid goes down, it is not providing security; it is providing a false sense of it.
This is why Nemtek’s battery backup system is a core part of what makes our installations a genuinely reliable security solution.
How Nemtek’s Battery Backup System Works
Nemtek energizers are designed with built-in battery backup as a standard feature. Here is how it works:
- During Normal Power: The energizer runs from mains electricity and simultaneously trickle-charges the battery.
- During a Power Cut: The energizer detects the failure within milliseconds and automatically switches to battery power. There is no gap or delay in your fence’s performance.
- When Power Returns: The energizer seamlessly switches back to mains supply and resumes charging the battery.
From an intruder’s perspective, nothing changes when the power goes out. The fence remains live and the alarm remains active.
The Nemtek 7Ah Backup Battery
The standard backup used in our installations is a 7Ah sealed lead-acid maintenance-free battery.
- Maintenance-Free: No topping up with water or corrosive spills.
- Automatic Charging: It is always ready because the energizer manages the charge.
- Duration: A fully charged 7Ah battery can run a typical energizer for 6 to 8 hours, covering the vast majority of load shedding events in Pakistan.
Extending Your Protection
For areas where outages regularly exceed 8 hours, we offer two advanced solutions:
1. Nemtek Battery Power Pack
This extended backup unit increases total capacity, allowing your fence to run for 15 to 16 hours. This is ideal for high-security installations or properties that are frequently unoccupied.
2. Solar-Powered Solutions
For the ultimate independence, Nemtek energizers are fully compatible with solar panel systems. A solar-powered fence operates entirely independently of the grid, meaning load shedding never affects your security.
Monitoring Your Backup Status
Knowing your fence is on battery power is vital for maintaining security. Nemtek offers several ways to stay informed:
- LCD Display: Models like the Druid show your battery’s charge level directly on the unit.
- WiFi Gateway: Sends a push notification to your smartphone the moment the power fails.
- GSM Module: Sends an SMS alert when the system switches to battery backup.
Common Mistakes to Avoid
In our experience at Durable Technologies, backup failures usually happen due to:
- Low-Quality Batteries: Generic batteries have a shorter life and lower actual capacity.
- Neglecting Replacement: Batteries typically need to be replaced every 3 to 5 years.
- Poor Installation: If the charging circuit isn’t wired correctly, the battery will never recharge.
At Durable Technologies, we include a high-quality battery and professional configuration in every installation to ensure you are never left vulnerable.
Frequently Asked Questions (FAQ)
Does the fence lose power for a moment during the switch? No. The switchover is automatic and instantaneous. There is no detectable gap in fence operation.
How often should I replace the backup battery? We recommend testing your battery every year and replacing it every 3 to 5 years to ensure it holds a full charge.
Can I upgrade my current fence to have better backup? Yes. In most cases, we can add a Battery Power Pack or a WiFi Gateway to your existing Nemtek system to improve your visibility and backup duration.
