Wet-pipe sprinkler systems
What are the "signs" to look for on the pressure guages of a wet-pipe sprinkler system to tell if the system has tripped?
A dry pipe system is easy, if the air pressure and water pressure guages are reading equal to each other, then it's tripped, but how do you tell on a wet-pipe system?

Depending upon the number of heads that have opened, there will likely not be a significant drop in pressure from the static pressure reading prior to the head activation.
Another indication is flooding inside the protected structure.

Water from the drains, motor gong sounding, "sweating" pipes. In a situation with multiple systems in one room you might find the activated zone by looking at the pipes that are sweating (cold water running through them) in the heated sprinkler room.

Any newer system is going to have a flow sensor in it as well, so just look for a lit indicator on the wall that corresponds to one of the pipes.Never argue with an Idiot. They drag you down to their level, and then beat you with experience!
