An audible “alarm” IF you loose 240v when on hookup?...

The reason I ask is....

Sometime in the early hrs ( whilst in bed) the power went off... ( i’m currently parked on the drive of an empty “doer-upper”... helping my lads with renovating it...)

BTW...The power cut was the whole area..

So unbeknown to me the Truma went into error mode ( it’s set to duel fuel winter mode)... and I was unaware (even after i’d got up and put light, tele and PC etc on) ...

That was until one of my lads txt’d asking if power off - he’d had notification from NPower that there was a problem...

I tend not to pay attention to the little Hookup symbol on the panel after establishing it’s plugged in..

Now!.. if this had happened in the freezing cold.... and for a longer period... the boiler dump valve may have kicked in etc..

One solution may be to take the fridge off of auto and put switch to 240v - and wait for that to bleep!.. but that defeats the object of Auto!..

So does anyone have anything - or retrofitted something to alert them?..

I bought a plug in alarm from ebay when some charming child unplugged my lead overnight. I haven't used it as yet as it is ridiculously load.

Well that`s our 14th year & still loving it.
Our fridge makes a right old din when it loses 240v power, certainly enough to wake you up.

We know if it goes off overnight as so does John's CPAP no good during the day though. Also had it unplugged by youths on a camp site, good job he can breathe without the machine.

We only use oil filled radiator when on hook up so if it goes cold, there's no power

Someone on Motorhome fun posted about their "power cut alarm" from Ebay.£5...they added a resistor to the circuit inside the plug as it was so loud

There seem to be many on eBay, most at reasonable price, although it looks like you will have to change the plug on most of them! Question is, do you really want to be woken by a 120Db alarm when the power drops??? Perhaps one of these, plus a defibrillator would be a good investment!!

We have a weather station in our van. If the temperature drops below a certain level, its alarm goes off.
This happens so rarely and usually in the night that neither of us can guess what the alarm is for. Stagger out of bed to search for the handbook in the now cold van. After several minutes I am very cold, shaking and trying to read small text without glasses. Give up and as I am now very cold I put on the Truma heater which takes an age to warm the van. I turn back to the now-silent weather stations manual and find that the alarm went off because the van was cold; I knew it was cold.
My heating had been provided on that occasion by a fan heater connected at a free Aires electrical point, that cut out at 4 a.m. It was mid-winter, France, with inches of snow on the ground.
Putting on a dressing gown and shoe-less I moved my outdoor socket to another post that was live.

All the gear, and no idea!
The panel in our encore 255 has a bleeping noise when our power is cut, I would have thought it would be common for that to happen, guess not!

Not complete solution but I leave the clothes peg on my water dump valve permanently so it never drops to automatically dump water.

Have wondered about using one of these, wasn’t sure if it might overload the campsite system, is yours a low voltage version?

Reasons please?


@houdini I am a full timer.. - I have adequate heating ... don’t hook up often... and storage would be an issue .. when not needed..
Does that suffice?.. :)

Thanks. Just wondered whether your reason was anything against that type of heating per se. :D

No ours doesn’t have an alarm but we have an aftermarket clock that goes off without leccy and flashes when it comes back on. When I get up for the loo in the night I can see it and know if all ok or there’s been a poet cut.

@Carol and Eddie and, I think, @andy63 use them ..I have one for hook up. It'snonly small and fits under the table ... Screwfix sell them so you can switch between 1000 and 2000 power.

I have a 700w one, it's small & keeps my PVC warm when on EHU - it has a thermostat & is normally only set to about halfway

I have heard of people successfully using smaller 450w oil filled radiators in their Mohos

I'm sure someone will post on this thread how careful we have to be because they leak - there's a fair bit of paranoia on here about lots of things :)

John asked about audible alarms to warn of ehu failure and now we are on heaters:LOL:
On the hook up alarm im sure something could be wired up using a relay and would be just a matter of sourcing a suitable alarm that didnt give you a heart attack :LOL:..never really given it any thought..
On the heater front i carry an electric convector with a few power options.. i find 750w keeps thevan comfortable most of the time..

Ours is a cheapy Lidl 1500W oil filled with 750/1500w switching. Waste of time the 1500w really, on 750w keeps the MH warm ... on 1500w the heating element keeps turning on and off as the temp rises meaning it is only connected probably half of the time giving the same general output as the 750w setting but without the eternal clicking of the thermostat. The problem is the heat transfer between the radiator and the air is not sufficient due to its small size.

@andy63 regards thread wandering, for me, this is nothing new, if you were to have a chat with me it would quickly become evident that half way through replying to your question I can forget the question ... pause .... look around ... see a butterfly ... and begin the chase... the advancing of the years
