HI
Can any Club Members or indeed anybody who uses a loop alarm on their boats at shows tell me where they obtained them. Or has anybody got a circuit diagram to make one.

I built one from a Maplins kit a few years back but it seems it's no longer available. This looks just like it though http://www.ebay.co.uk/itm/LOOP-ALARM-/290890127857?pt=UK_DIY_Material_Electrical_Fittings_MJ&hash=item43ba6719f1 (http://www.ebay.co.uk/itm/LOOP-ALARM-/290890127857?pt=UK_DIY_Material_Electrical_Fittings_MJ&hash=item43ba6719f1)
Can't be bad for the current bid price!!

Not cheap at GBP 38.88, but battery operated, and key, for on off. Designed for what you want it for, security at shows.

Hello
why put it? I made dozens of exhibitions in the UK and I've never had a problem with theft
And it is very ugly .......
France in person does this and it is very rare that a flight.
Flights take place at the end when you put in the car, this is the risk

I seem to remember that they looped them at the Warwick show some years ago, may only have been the ones near the door before the entrance was widened.
-
:-)
yes we were near the door, Warwick, twice, and then on the sides and center. Never a problem.
Very nice exposure and good atmosphere, we had fun :-))
-
I don't know if anyone here has experienced model theft from a show?
I have done other shows, and theft of personal items (esp laptops and phones) usually occurs during the breakdown phase (clearing up at the end of the show).
The cheekiest one we had was a 42" plasma TV (when they were top technology) disappearing from the crowded stand, mid show, in Russia.
-
Yep. We left a box of batteries on the stand as we cleared up after the last Blackpool show. Sure enough, two very expensive F-size NiMH 7.2v packs went walkies. That said, no loop alarm would have prevented it. You tend to trust folk and then regret it.

This isn't what you're asking about, but it's something I noticed a while back in relation to a completely different application, although it might be of use (for some users) on here.
A couple of years back, the Wilko/Wilkinson store had pairs of magnetic window alarms. They were about the size of a small match-box and operated via a reed switch. When the two components were seperated, the alarm would scream.
They currently have a similar key-operated item (Shed Alarm) - which muight do the job for a fiver. http://www.wilko.com/house-garage+shed-alarms/wireless-alarm-door-and-window/invt/0276334 (http://www.wilko.com/house-garage+shed-alarms/wireless-alarm-door-and-window/invt/0276334) - especialy if the alarm is wired to the model, although the magnet could go in the hull and the alarm on boat stand.
Anyway, as I said, it's not what your asking about, but may be an economical solution to suit certain applications. Including the unfortunate battery theft mentioned above...
Andy
p.s. Just thought - Those personal alarms which require the removal of a 'stopper' plug may also serve a similar purpose. Just remember to change the draw string for something less easy to cut.

Didn't Deans Marine have a boat 'disappear' off their stand at Blackpool last year?
-
:((
Hello
Blackpool is it a strange place?
we are designers, we should be honest ....... between
With us a very rare locomotive tens of Kg disappeared exposure. Messages have been on forums all over europe and uk, we have never heard of this locomotive

You know, it beggers belief that stuff like this happen. I mean 99% of folk that go these shows are there for the love of model boats etc, they build them, display them, run them, they know the value of these models-not just monetary but in time etc. Why some folk would want to try and nick one is beyond me, but there will always be folk like this...such a sad thing.
Saying that, many moons ago we were on holiday and stopped off for a picnic, there was some model plane guys on the field. One had a lovely large B17 flying fortress-he flew it, landed it, took the wings off and it all folded away in his trailer. He got another plane and was flying that, while this was happening someone unhitched his trailer and nicked it and the plane!

Yes, but that was an enterprising interloper out of hours due presumably ("presumably" for legal reasons) to an assumed lapse of venue security before opening on the Sunday morning, not a light fingered visitor during show hours.

Here's a cheap option perhaps - 2x magnetic window alarms as mentioned by adross for £1.49

May or may not suit your application, but for the price might be worth a try. :-))

a good few year ago while at weymouth show there was a 5ft model canal boat stolen <*< with lots of people there too they found the model a few hours later in a bin at the back of one of the hotels <*< i dont think there was anything missing only some damage from where it was chucked into the bin!!!
i have a strong cord that lashed all my boat together while i was at that show but in general its normaly quiet safe at shows

That's the chappies - Noisy little b*****s they are too. All you need to do is doctor the switch slightly. I thought of either a shim to prevent it sliding back to the off position, or cutting it down and operating it with a pin.
A that price though, it's got to be worth thinking about as a back up if nothing else.

The alarm is to protect all the boats on our stand so the loop needs to be about 30mtrs long so these shed alarms are not suitable. I found this website www.selecsecurityproducts.co.uk (http://www.selecsecurityproducts.co.uk) 1 for £24.49 plus vat delivery, cables from Squires 1.2mtr £1.15 and 5 mtr £1.99.
Thanks for you suggestions

Slightly less encouraged to take my models to shows now!
Has anyone thought of making a loop alarm?
A quick Google search reveals a fairly simple circuit and a spare 7.2V or 12V lead acid battery could be used to power it, sirens must be cheap to find and the loop could be made from old bell type wire or pretty much any wire come to that, only one core needed and then you could make it any length you wanted.
Could possibly work out separate circuits for more than one loop or just make 3 or 4 of them, one for the boats on each table? Put a Tamiya type battery connector in the loop for connection and re-connection when moving the models and job done?

Some of these cables look like phono cables, it may be possible to extend the cables to the 30m you require using connectors. Or to have a local TV repair shop knock up a custom 30m cable.
Although a number of interconnected shorter cables would be easier to thread and unthread through a series of models.
-
@craig
You are correct, it would seem simple enough. You could use a constant ringing type doorbell, although I am sure there are plenty of sirens out there.
-
What about something like this.... only larger

Actually thinking about it I have a smoke alarm at home sitting on the table that has a sticker on it saying "Replace by Dec 2010" The smoke detecting abilities of smoke alarms does degrade over time, hence why they should be replaced but their ability to make hell of a noise doesn't!
I'll have a think and see if I can utilize that in some way and come up with a cheap solution. Would also double up as a warning if the display table bursts into flames! :)

Have you used it? it is very effective in order to catch the thief and there is no need because he screams siren strong

It would make one heck of a mess of your model boat though.

They are phono cables. The price for them from Squires it is very reasonable when you look at the price of connectors on there own.

Shed alarm should work, just replace the cable with a longer one..
By the way, the loop alarms (at least the ones we used when I worked for Curry's and Granada in the 80's) are quite easy to bypass as I was once shown :police:
See 2 pictures from the Warwick Show 2007
-
Also these, Not sure if it was a requirement of the show, but some stands do not seem to be wired, take a look at the last picture, There is definitely somebody eyeing up a few models there.. :}
-
From shows I have attended we always had someone to man the stand to keep an eye on things even during the pack up, some shows have a very good security system Harrogate is a good example the models have to be signed in by a steward two cards are singed one stays with the model for the whole show one stays with the person who owns that model no models can be taken out during the show they are there for 3 days I guess everywhere is different really

Be wary, the man in blue is everywhere, everywhere he takes pictures of models, there can be seen hide a battleship in the collar of his shirt. It is not large, these are bags to hide models

Meridienne used to supply loop alarms for the International Model Boat Show, and they have a system for booking models in and out.

At the Model Boat Convention the stands have to be manned by at least one club member. All models are on the stands for the duration of the show. With any sales from the chandlery the purchaser is given a receipt and they contact a committee member who checks the receipt and escorts them out.
