Are there any new proxies the school system have not found?
Could be a bad alarm control unit but mostlikly you have a short in a wire or a bare wire that's touching metal that is usually the cause of alarm systems going off and being two sensitive if I was you I would have it looked at but if you do have a short or bare wire there is no fire risk they don't carry enough electricity to start a fire plus its DC power not AC
With the sprinkler systems you do not see the smoke detectors like you do in a house. They are equipt with sensors I do believe. It's a newer updated system, and they are not like the olds ones. I watched the installation of that system at a place I worked once. It's not what you're used to. I don't really know how to describe it other than that.
