Which instrument verifies water pressure across the sprinkler network?

• A. Pressure Gauges
• B. Alarms
• C. Piping Support
• D. Open-Grid Ceilings

Answer: (A)

The main idea is to have a device that reads actual pressure in the system so you can confirm the water pressure at different points meets the design requirements. Pressure gauges provide that direct reading. They are placed at strategic points—such as the main riser, test connections, and representative branch lines—so you can verify that the residual pressure stays above the minimum needed to deliver adequate sprinkler flow to all areas. This helps catch issues like a restricted supply, valve misalignment, or pump problems before they affect coverage. Alarms indicate that flow or a fault has occurred but do not continuously show system pressure; piping supports and open-grid ceilings are not measurement devices.
