Electric Fence Timed fence lights - How many can I have on a fence?

[Jam Sandwich]

So I've been buying Nemtek electric fence 'timed lights' for the fence. Its quite a long stretch of fence and includes a car park area.
Ive got around 7 lights on the fence in various areas so if you are in the kitchen you can see a couple, or from the office, or the deck, car park etc.
Its so my staff can see at a quick glance if there is a problem somewhere when they are working or walking around.

The energiser is a Druid 114. Now some of the lights after a few months fail, Ive taken a couple back and had swop outs and when I went to the shop the other day I asked the guy if these lights are maybe only rated for certain voltages. He said no, you can use them on any fence (apparently the blue ones are for the stranded wire like at home and the black ones for the solid strand wire such as in a game reserve).

He then asked how many I have on the fence and when I told him the amount he said you cant have more than 4 on a fence in any zone (my fence, although a long stretch is just one zone).

Does this sound correct? The justification was that it creates too much resistance and voltage drop.
(I should add that the lights do have polarity and are wired in as such.)

Never knew these existed. What's the price and how does the timing work?

They just use the fence voltage pulses to power their LEDs so you can see if the fence is on. There's no timing as such...



Putting too many on a segment is just going to trigger the energiser to think the fence is shorted or damaged because there's too much current going from the live to the ground w ire.

They are from about R150 onwards...apparently the pulsing or flashing of the light slows down with less voltage...they work well for a quick glance especially at night.

I think I'm going to test the voltage and then remove them all and test again and see what's the difference. Unfortunately the app for the energiser only shows the fence as armed or not and if the siren is triggered. It doesn't indicate what the voltage is on the fence.

Keep them facing inside if you use, as the not blinking at night is an obvious "the fence isn't working" sign.

Yup. I have two . One on my gate section , which of course 'turns' off when the gate is open and disconnected from the thingee it connects into

Another on the other side of the wall.

With these two, I can see quickly if the fence is on or off cos we do have the ability to turn off the energiser with a remote, and the problem is sometimes, that button is pressed on our sherlo remote and we don't realise the fence is not 'energised'. Also have a home automation smart socket on the energiser plug. If I see it's below 5w (it means it's not on, so there is proactive alert there too)

How are you going to test the voltage, out of curiosity?

It doesn't slow down. You just get fewer of the LEDs lighting up as the voltage decreases.

Lick your fingers before testing to get better conductivity.

The voltage should only drop once you overload it. If you can find the current draw for them its easier to calculate how many you can add. I imagine its only 50mA or so so 20 of them would be an amp.

im guessing even less than 50ma

On these all of the 4 LEDs still light up together but with a slower rate pulsing rate.

• Normal flashing rate: Voltage is over ~7.5 kV.
• 25% slower than normal: Voltage is between 7.5 kV and 3 kV.
• 50% slower than normal: Voltage is between 3 kV and 2.5 kV.
• 75% slower than normal: Voltage has dropped below ~2.5 kV (down to 0.9 kV). [1]

With this.

Guy in the shop said it would be a significant difference if I removed them all and tested?

Lol...I've caught my forehead on that sodding fence before..I won't be licking fingers and touching wires that's for sure ..!

do let us know the results . i only have 2 . 1 on each of the end points of the fence

I personally can't see it making much of a difference. I do need a lot of lights so people are aware of the fence status as I'm not always there

crime is on the increase in that area. The energiser isn't centrally located with people able to notice what's the status on it so without the lights you can't really tell if it's on or not.....

I was carrying my son one time, and as I opened the small gate with the electrified rope fence at our holiday place and walked through the gate, I felt one moerse fokken shock. Turns out he grabbed the rope while I was going through the gate. Never seen his eyes that big.

He must have been 2-3 years old at the time. Lmfao.

JVA energizer got a reading screen build in. The enegizer does have a place to show it is on, like a 12 volt output. you could place some led's on that line to show it is on. But a fence should always be on, so always handle as such.
