Here is a full trip test on a dry sprinkler system. There are two gauges here. The one on the right is the water gauge, and air on the left. This test is to simulate if a sprinkler head is blown in case of fire. This is a small parkade, so the times will be fast.
In a dry sprinkler system the pipes are filled with air instead of water. This is to prevent freezing in the winter months. The device that separates the air and the water is called a dry pipe valve. It is a valve that has a clapper in it that is down when the system is supervised with air. When the air is released, the air pressure drops and eventually the pressure of the air cannot hold down the clapper. At this point the dry pipe valve trips, and water flows into the pipes to put the fire out.
