When the fire fighting system starts increasing pressure, water will flow into the system until reaching a balance between the water supplying with the system pressure. And the alarm check valve can put pressure on the fire pumps valve to prevent the water backflowing. Once the pressure comes to balance, the alarm check valve will be in operation state, and the middle chamber of its seat ring will be sealed. So if the alarm check valve was set at maintenance state, there will no alarm port to the alarm facility (alarm pressure switch).
