The cheapest moment to stop an intruder is before he reaches the window. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Alarms trigger on cuts, shorts and low voltage. - Zones tell responders where to go. - Zoned fences are easier to fault-find and maintain. Quick answer A monitored energizer checks the fence voltage and raises an alarm when a wire is cut, shorted to earth or pulled together. Splitting a boundary into zones (separate sections, each monitored) means the alarm tells guards which stretch has the problem, and lets one section be switched off for repairs without disabling the whole fence.

False alarms? See [electric fence alarm fault](https://qyvea.co.ke/electric-fence-alarm-fault-kenya). ## Frequently asked questions How many zones should my fence have? Enough that each zone is short enough to find a problem quickly; long boundaries and estates benefit most. Why does my fence alarm keep going off? Usually vegetation, broken wires, loose connections or poor earthing. Can the fence alarm send me a message? With a GSM or monitoring module linked to the energizer, yes. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
