dwdave Posted August 5, 2015 Share Posted August 5, 2015 I'm not with the panel nor my meter but can anyone tell me what the voltage of the galaxies alarm circuits are? I might guess at 12v because everything else post ac is 12v dc but I'd rather check. Quote 'till the next question ... Link to comment Share on other sites More sharing options...
JB_ Posted August 5, 2015 Share Posted August 5, 2015 Far as I remember, they are approximately 12volt when totally open circuit(nothing connected). Drop to 1.2v when the circuit is closed (1000ohms) and around 1.8v when the circuit is open (2000ohms). Why do you ask? Its not normally something that would ever get measured and it's not a 12v source you can actually power anything from. Quote Link to comment Share on other sites More sharing options...
dwdave Posted August 5, 2015 Author Share Posted August 5, 2015 I was just looking at a little shock sensor for an arduino which is just a n/c circuit. I don't think it would work with the panel though. Quote 'till the next question ... Link to comment Share on other sites More sharing options...
charlie6 Posted August 5, 2015 Share Posted August 5, 2015 Why do you think it wouldn't work, it's normally closed ? Quote Link to comment Share on other sites More sharing options...
dwdave Posted August 5, 2015 Author Share Posted August 5, 2015 Not sure I could work out how to connect it, it is n/c but runs a much lower voltage (3-5v). I could use a resistor to bring down the voltage though. Type this number into eBay 301361704368 Quote 'till the next question ... Link to comment Share on other sites More sharing options...

dwdave Posted August 5, 2015 Author Share Posted August 5, 2015 But could the arduino one work? Quote 'till the next question ... Link to comment Share on other sites More sharing options...

dwdave Posted August 5, 2015 Author Share Posted August 5, 2015 Haha, I want to use it for both the galaxy and an arduino / pi. I've got some vipers or the texecom impaq range earmarked for proper use. Quote 'till the next question ... Link to comment Share on other sites More sharing options...
MrHappy Posted August 5, 2015 Share Posted August 5, 2015 (edited) spend the £1 & show us how's it done...however I'd assume-you'll need to convert 12-5v to power it then,open collectors operating at 5v would need a relay for the galaxy ?used as an alarm shock sensor, as unstable as the middle east... add a volt free relay on the pi to operate when the shock does Edited August 5, 2015 by MrHappy Quote Mr Veritas God Link to comment Share on other sites More sharing options...
