Fixed monitors, permit the use of fixed hydrant-mounted monitors or individual monitors connected to the fire main to apply water to the fire area. In this case, water is applied by operators manually opening valves to allow the flow of water. This procedure exposes operators to high heat fluxes and places them close to vessels under fire conditions. It is important to carefully study the plant and vessel layout if this method is elected. Proper placement, location, and quantity of fixed monitors must be reviewed and field tested to ensure that proper application and even distribution of water to all parts of the vessel are accomplished. In some cases, remote activation and operation are suggested when proper spacing of monitors is not a possibility. Additionally, annual testing and preventative maintenance are necessary to ensure parameters have not changed and coverage is still adequate.

Indeed. You can find further detail within OISD GDN 115, 116 and more specifically within STD 114, 150 and 158.
