Div 21 — Fire Suppression
Fire Suppression
NFPA 13 automatic sprinkler design — occupancy hazard classification, density/area demand, heads/risers/valves, waterflow + tamper devices, and the fire-pump screen.
Core Engine
SprinklerSpecCore Engine
Brief → occupancy hazard classification → NFPA 13 density/area demand → system type → heads/valves/devices BOM → fire-pump screen.
“40,000 sf retail + warehouse” → OH-2 wet system, head count + demand gpm @ psi
What you do
Describe the building, area, occupancy, and any unheated/water-sensitive areas (parking, data center, storage).
What you get
Occupancy hazard classification (light / ordinary / extra), system type (wet / dry / preaction / deluge / ESFR), sprinkler heads by response/K-factor/temperature, riser/control valves, waterflow + tamper devices (→ fire alarm), pipe type, hangers/seismic bracing, FDC, backflow + fire pump where the supply demands it — plus head-count, demand (gpm @ psi), hose/duration, and supply-adequacy checks and a device BOM.

Hydraulic / Demand Calc
NFPA 13 density/area take-off (head count, demand gpm, hose + duration, risers) + a water-supply / fire-pump screen.
30,000 sf / Ordinary Hazard 2 / 1 floor → heads, demand gpm @ psi, pump needed?
