Level four is not always used, and when it is, there's a decimal between it and level three, as most specification numbers are only six digits. Let me show you an example. Here's a number for point address fire alarm system 28 31 02. Division number, or level one, is 28. 31 is a level two number, and the 02 is a level three number. If a level four number were being used, you see the decimal point would be added and that subsequent number would be added, 16. Let's go to a real specification and see if we can find this. Here it is, point address fire alarm system. You'll see it's listed after 27 0510, and below it, going further down. Keep going…
