From what I remember, there are quite a few questions regarding monitoring sprinkler systems, such as how many valves can you supervise with one circuit, how many flow switches can be supervised on one circuit, and waterflow bell delay time. It has been about a decade since I have seen the test so I don't remember too much more than that of what they ask you, but I believe they offer some practice tests which are very helpful. They did when I took the test and I don't know that I would have passed without those practice tests. They showed me what to study. Best of luck!
