Guest Peter James Posted February 9, 2007 Share Posted February 9, 2007 All alarms are 12vdc but you are as everyone else has pointed out you are limitted to the size of your battery and how often you can change/charge it Pete Link to comment Share on other sites More sharing options...
arfur mo Posted February 9, 2007 Share Posted February 9, 2007 most large caravan shops sell alarms designed for touring caravans which are parked on fields over winter. you could also try boat chandlers as they offer similar systems for can you guess it? - boats. they use door contacts and trembler's (which require no current) for detection, scope paging if i remember correctly also did one. as for battery life modern systems designed for buildings as has been said will not last, but i could dust off a few designers based on simple cmos technology if you handy with a soldering iron. try these for starters http://uk.geocities.com/ronj_1217/mini.html regs alan If you think education is difficult, try being stupid!!!!

grocerjack Posted February 11, 2007 Author Share Posted February 11, 2007 Thanks everyone = keep the suggestions coming. Solar power would be great because where right on the Med and the place has around 320 days of sunshine per year - so if anyone knows of anything solar powered. It is a fixed mobile home as opposed to a caravan that can be towed. The Hoyle Exit guard looks interesting as well - is it easy to fit by someone like me (i.e a normal DIY sort of bloke)? We've got a bit of battle on with the site owners (Siblu) and we as a group of owners have suggezted a wireless system, but they're just not interested. All we get is the corporate //.B.W.F.// of "having security intersts at heart, striving to improve security etc) and yet anyone can go onto the site during the close season more or less unchallenged. Whatever solution I go for will be advised to a large number of other UK, and possibly French owners so it could be a good ad for a reliable system especially one that operates on Solar/battery power.

norman Posted February 11, 2007 Share Posted February 11, 2007 Ensure if you go the solar panel way that it is regulated as the cheapies are not and will boil the battery dry, also make sure as a rule of thumb that the panel will supply more than the alarm takes in quiescent mode. Here's one I made earlier. Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...

uski Posted February 25, 2007 Share Posted February 25, 2007 FYI, alarms system cannot be linked directly to the police in France (but they can be to monitoring stations), so avoid saying that as it is not very realistic As for the solar system... hmm... isn't it like putting the battery and the main supply of the siren directly accessible to the bad guys ? See what I mean ? :/ Thieves may think "oh he has something to protect" and prepare their attack :/ Link to comment Share on other sites More sharing options...
