I have a decent understanding of electronics, but having been in sales rather than installation, the nuts and bolts of wiring are certainly not my strength. Anyhow, what I want to do is very simple and I'm almost postive that I should be able to do it. In any case, we lost a number of electronics from a lightning strike a couple of weeks back. From simple deductive reasoning, I think the surge came in through phone lines. It took out the modem, our phone system, my ipod cable (but not the ipod itself) and a control panel in one of our alarm systems, among other things. The Ipod was plugged into the same wall socket as the phone system control box and of course, everything else was connected via phone cables from there. In any case, whether that was the path, really doesn't matter. I have pieced the alarm back together, but it is cumbersome at the least. The short question is that I have a couple of "zone expander" boxes and they still work perfectly, but they are designed to connect into a main alarm control board. Not only do they no longer make the model we had, they are also rather expensive and since we pieced our system together, we were really never using much of the main brain anyhow. The expander boxes monitor their zones independently. They provide automatic bypass should a zone continue to alert, and they also provide memory to let us know what zone(s) was/were triggered. Incidentally, this is a 12V system which is powered with deepcycle batteries that are charged with a maintenance free, completely automatic charge system. Again, we have 48 hours of backup, should power fail completely. In any case, here is the simple wiring question:
What I need is to wire up a relay to each of the expander boxes so that they will trigger a 12V signal -- not that it matters, but I could use a positive or a triggered ground -- when they receive either an open or closed circuit from the expander box. I know I should be able to do this, but keep spinning my wheels.
If possible, I want to use the 5-pin Bosch relays. Not only do I have them already, as well as pre-wired sockets for them, but they have proven to be very reliable,
The pins are labeled 30, 85, 86, 87 and 87a.
Again, I have access to 12V right there, and everything operates on DC 12V. The trigger out of the expander boxes can be either a common and closed circuit or a common and an open circuit. I should be able to do what I'm trying to do. The bottom line is that some configuration of the 5 pin relay should work as I need, and that is to throw 12V signal when receiving either an open or closed circuit signal.
Sorry about the lengthy post, but I just wanted to give you the insight, in case it matters. Thanks!
