#358 How Much Water Pressure is Required for Fire

Determining sprinkler water pressure-demand with design areas Fire protection engineers design sprinkler systems to control or suppress fires in the most challenging locations within a system. The building the system is protecting may have a variety of different hazards and fuel loads.

2.5" Adjustable Zone Control Pressure Regulating Valve

Model Number:4036 and 4038. Product Function:Used as a zone control valve for in-line application to regulate high-pressure sprinkler, standpipe and combined fire protection systems. Indicator bonnet shows whether valve is opened or closed. Adjustable indicating scale permits easy field setting. The valve is used to regulate inlet pressure to 400 PSI/27.5 bars. APPLYING VARIABLE SPEED PRESSURE LIMITING NFPA 13 and NFPA 14 allow the use of pressure control valves to reduce pressure to a sprinkler or standpipe system. However, currently, the use of master pressure reducing valves (a single pressure reducing that controls the water supply to multiple fire protection systems) is

Flow Switches vs. Pressure Switches in Fire Protection

In turn, it sends a signal to a fire alarm control panel, a notification device (like a bell), or both. Fire sprinkler pressure switches, on the other hand, watch for changes in pressure. Major manufacturers offer two main types of pressure switch:Alarm pressure switches, which monitor changes in water pressure Flow Switches vs. Pressure Switches in Fire Protection When that pressure rises or falls too far, the electrical contacts close, forming a circuit that sends a warning signal to a fire alarm control panel or sounds an alarm. Most pressure switches are adjustable, allowing installers to decide exactly what change in

    Pressure Maintenance (Jockey) Pumps Fire Protection

    1) The jockey pump stop point should equal the pump churn pressure plus the minimum static supply pressure. 2) The jockey pump start point should be at least 10 psi (0.68 bar) less than the jockey pump stop point. 3) The fire pump start point should be 5 psi (0.34 bar) less than the jockey pump start point. Pressure Maintenance (Jockey) Pumps Fire Protection Most stationary fire pump assemblies are installed with devices that automatically sense a pressure loss in a fire protection system, and start running to supply water or boost pressure in that system. From time to time, though, small water leaks, unwanted pressure drops, or even temperature changes may fool the fire pump into starting
