Energy-Jason Posted January 1, 2017 Share Posted January 1, 2017 Hi All. I need a bit of help, im playing a bit with a IR camera that closes a external relay of a 12V circuit. The IR is in the garage so I hope it doesn't trigger by wind and so on. My question is, the typical sirens that ADT would install at your home. In order to make that oscillating tone , I imagine this wouod required a circuit? Or is this build into the back of the DC siren. Please excuse my ignorance, I just enjoy playing. Any help would be great. I am wondering if this is something I can buy off ebay. I love ebay. I buy all my glasses frames there, hehe. @superdiy, @JDP @plonkster, @Chris Hobsonthis might be up your alley. Plonk, Chris or JDP. Will appreciate.

___ Posted January 1, 2017 Share Posted January 1, 2017 Built into the unit. The alarm just supplies it with 12V.Sent from my GT-I9195 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Guest Posted January 1, 2017 Share Posted January 1, 2017 Yep as plonky said you just give it power and it will sound the correct way. ACDC express has a lot of them on the shelf. You can ask them to hook one up and you will see how they work. Quote Link to comment Share on other sites More sharing options...
