Wu, PE, CBO, is a managing engineer at Exponent, Inc., a scientific and engineering consulting firm. The area of fire spread corresponds to the empirically derived area where fire sprinklers are expected to activate and subsequently contain the fire, referred to as the “design area” or “hydraulically most-remote area.” The simultaneous flow of sprinklers within the design area produces a hydraulic demand of both the flow of water (gallons per minute - gpm) and the system pressure (pounds per square inch - psi) needed to produce the proper sprinkler discharge density and droplet pattern over the design area. directions for lines with sprinklers operating in the remote area. The standard assumes a fire involving a particular fuel class and load will grow at a predetermined rate and intensity and will spread until it is confined by either the physical construction of the structure or operation of the fire sprinkler system. automatic fire sprinkler system design, installation, testing and inspection in the. This means they cannot be blocked by beams, trusses, soffits, or any other elements of your building’s construction. Show area used in hydraulic calculation(s). Show most hydraulically remote area(s) 10.
Show locations of all sprinklers by type - Must correspond to those shown in legend Must correspond to temperature rating shown in legend. Sprinkler heads must be unobstructed to provide maximum flow to the areas that need it. Indicate design type (gridded, closed-loop, etc.), area, and number of sprinklers in design area. AGFs Model 1211 RemoteTEST saves time and money by allowing the fire sprinkler inspectors test to be performed from a single location through a local switch.
Upright sprinklers are designed for installation on the top of sprinkler piping, with the deflector positioned above the orifice. NFPA 13, Standard for the Installation of Automatic Sprinkler Systems bases its fire control approach on occupancy hazards associated with specific occupancies: light, ordinary, extra hazard occupancy classifications. Because fire sprinklers are heat activated, sprinkler heads must be located high up on or near the ceiling. Sprinkler system designs for this sprinkler type are also classified by the number of sprinklers expected to operate during a fire at a given minimum required pressure.
