Anthony Hart Posted March 12, 2021 Share Posted March 12, 2021 Hi there. I'm totally new at this. The problem is I bought a wireless home burglar system from ebay some years ago and it became defective. I went ahead and bought what looked like a similar one but it wasn't and the new panel is not connecting with my old sensors. Both say they use 433mhz to work. My old sensors have a jumper block whereas the new ones don't. Anybody has any ideas how I can get the old sensors to work with the new panel?

sixwheeledbeast Posted March 12, 2021 Share Posted March 12, 2021 They are still possibly not compatible. Jumpers or DIP switches would indicate manually setting channels whereas without would have an enrollment method via the panel. You don't mention any model but TBH it all sound very old or DIY and not something anyone here would have used, most stuff moved to 868Mhz a decade ago.

PeterJames Posted March 12, 2021 Share Posted March 12, 2021 Just because something is the same frequency doesnt mean its compatible in the same way a yellow door from a ford wont fit a yellow vauxhall. You need to buy everything from the same manufacturer, and in most cases the same model too. Quote Link to comment Share on other sites More sharing options...

Anthony Hart Posted March 12, 2021 Author Share Posted March 12, 2021 Hi and thanks for all the replies. I'm really not sure about the actual age of the systems in question but they were new, according to the Ebay seller. And yes, there are pretty cheap (as I am) $40.00 t0 $50.00 US for a fair amount of sensors. a siren etc. etc. You can check them out there easily if you search for "wireless burglar alarm systems" and they sure do work! To address Mr. Sixwheeldbeast, you are correct my friend. The new panel uses an enrollment system unlike the old one which, as I mentioned, appears to use the jumper block. Not being sure how these things connect to each other I nevertheless suspect that it's not too complicated to get them to communicate. I would think that if I can determine what frequency the new panel uses to signal its sensors I should be able to program the jumpers in the old sensors appropriately. Am i making sense? I am attaching some pics to help out anyone who cares to take another shot at it. Quote Link to comment Share on other sites More sharing options...

Am i making sense? The new kit is possibly rolling code your old kit is fixed frequency. That said the newer detectors have antennas. I went to a couple of Chinese alarm factories around 5 years ago and they were not producing detectors with antennas in, so I would say those detectors are old stock which would suggest old tech Quote Link to comment Share on other sites More sharing options...

If it is this rolling code thing does that mean that what I want to do is impossible? Quote Link to comment Share on other sites More sharing options...
